Abstract

This scientific report provides an update of the Xylella spp. host plant database, aiming to provide information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp. Upon a mandate of the European Commission, EFSA created and regularly updates a database of host plant species of Xylella spp. The current mandate covers the period 2021–2026. This report is related to the eighth version of the database published in Zenodo in the EFSA Knowledge Junction community, covering literature published from 1 July 2022 up to 31 December 2022, and recent Europhyt outbreak notifications. Informative data have been extracted from 21 selected publications. Twelve new host plants were identified and added to the database. Nine plant species were reported from Portugal and naturally infected by subsp. multiplex or unknown (i.e. not reported). Three plant species were successfully artificially infected by subsp. fastidiosa. No additional data were retrieved for X. taiwanensis, and no additional STs were identified worldwide. New information on the tolerant/resistant response of plant species to X. fastidiosa infection were added to the database. The overall number of Xylella spp. host plants determined with at least two different detection methods or positive with one method (between sequencing and pure culture isolation) reaches now 433 plant species, 197 genera and 68 families. Such numbers rise to 690 plant species, 306 genera and 88 families if considered regardless of the detection methods applied.

Keywords: Xylella spp., Xylella fastidiosa, host plants, database, data extraction, subspecies, sequence types

1. Introduction

1.1. Background and terms of reference as provided by the requestor

In the context of Article 31 of Regulation (EC) No 178/2002, EFSA was asked by the European Commission DG SANTE to provide technical assistance in the field of plant health as regards the regulated harmful organism Xylella fastidiosa, as per letter to EFSA's Director dated 30 June 2016 (Reference ARES (2016) 3126989).

EFSA was requested to further specify and update the host plants database of X. fastidiosa available in 2016 (EFSA, 2016) taking into account the different X. fastidiosa subspecies and strains (with particular reference to the European isolates), with the inclusion of information on non‐susceptible plants and varieties and negative results of diagnostic tests when available. EFSA was requested to maintain and update this database periodically and to make new releases available on the EFSA website, together with a Scientific Report. The database should focus on plants confirmed to be infected by at least two detection methods in field conditions or via vector transmission under experimental conditions. Such request was for the period 2016–2020.

This mandate was extended by the European Commission DG SANTE for the period 2021–2026, with the aim to continue the update of that database. EFSA is requested to deliver two updates per year of the database.

1.2. Interpretation of the terms of reference

EFSA delivered in September 2018 a renovated database of host plants of Xylella spp., taking into account both species of the genus Xylella (X. fastidiosa and X. taiwanensis) (EFSA, 2018), which was last updated in January 2023 (EFSA, 2023). Raw data and interactive reports were published in Zenodo 1 in the EFSA Knowledge Junction community and in Microstrategy 2 platform, together with a Scientific Report.

As per terms of reference (ToR), EFSA was requested to maintain and update the Xylella spp. host plant database for the period 2021–2026, and to publish new releases online together with a report twice per year. This scientific report provides a new update on the database of host plants of Xylella spp. published in January 2023 (EFSA, 2023). An extensive literature search was conducted to retrieve recent publications on the topic and new informative data on host plant species of Xylella spp. were collected. Such report provides information on the literature review and a detailed view on the currently known host plants of Xylella spp.

2. Data and methodologies

The methodologies developed for the Xylella spp. host plant database published in 2018 (EFSA, 2018) were applied in this report.

The process was divided in the following steps:

  • Extensive literature search to identify relevant references.

  • Selection of studies based on title, abstract and full text.

  • Data extraction of relevant information.

  • Data analysis and reporting.

2.1. Extensive literature search

The review question, ‘Which plant species can host Xylella / Xylella associated disease?’ was broken down into key stages using the P/O conceptual model described in the EFSA systematic review guidance (EFSA, 2010):

  • Population of interest (P)

The population of interest is that of plant species, worldwide.

  • Outcome (condition of interest) (O)

The outcome (condition of interest) is that of Xylella spp. infection.

Two main elements were considered for the extensive literature search: The sources of information (Table 1) to be consulted and the search strategy (Table 2).

2.1.1. Information sources

The search strategy was run in all databases listed in Table 1 via the Web of Science (Clarivate Analytics) and Scopus platforms with no language or document type restriction.

2.1.2. Search terms

The syntax of the search string, developed for the Xylella spp. host plants database published in 2018 (EFSA, 2018), was adapted and run into each platform databases listed in Table 1 on 1 February 2023. As the scope of the search was to retrieve references published after June 2022, the selected time span was from 1 July 2022 up to 31 December 2022. The search strings and the number of retrieved references are shown in Table 2.

The collected references were downloaded and imported into an EndNote X9 library (Clarivate Analytics). Duplicates and references already included in the update published in January 2023 (EFSA, 2023) were removed using EndNote X9 and the remaining references were uploaded on DistillerSR online 3 together with the full texts in portable document format (pdf).

Twenty‐four Europhyt outbreak notifications 4 (accessed on 1 March 2023) were also included.

2.2. Study selection

The collected references were screened for relevance in two steps:

  1. Title and abstract screening.

  2. Full‐text screening of the references that passed the first step.

Inclusion/exclusion criteria were applied in each step and two reviewers worked in parallel screening the references.

The first step required the reviewers to answer two questions, listed in Table 3, considering only title and abstract of the references. The aim of this step was to select only references presenting original research data on Xylella or Xylella‐associated disease.

Table 3.

2.3. Data extraction

Informative data listed in Table 5 were extracted from the selected references. For each reference, the first reviewer performed the data extraction whereas the second reviewer conducted the quality check of the extracted data. Data extraction from each reference can generate one or several records. A record is defined as a unique combination of data related to a detection event, and it corresponds to a single Excel row of the files published in Zenodo (see Section 2.4.1).

2.4. Data warehouse

A harmonised data model has been established to collect data on Xylella spp. host plants. The aim was to establish a harmonised data flow for the collection and the collation of an extensive literature review generated data in the plant health domain. Data are stored in EFSA Scientific Data Warehouse (S‐DWH), after that an ETL (Extract, Transform, Load) procedure is applied in order to harmonise and calculated the statistics.

2.4.1. Data management

The collected data have been submitted to the EFSA Data Collection Framework (DCF). DCF is the upfront system in the EFSA pipeline of data collection tools and allows a first step of harmonisation against the EFSA controlled reference terminology (aka EFSA catalogues). Data have been then included in the S‐DWH by means of a standardised Extract Transform Load (ETL) procedure and they have been further analysed and managed to generate needed statistics.

Data are available as interactive reports on the Microstrategy platform at the following link: https://www.efsa.europa.eu/en/microstrategy/xylella

Raw data and related metadata are published in Zenodo in the EFSA Knowledge Junction community, this report refers to version 8 (https://doi.org/10.5281/zenodo.1339343).

2.4.2. Data reporting

Data reporting was designed to distinguish the Xylella spp. host plant species, based on the number and type of detection methods applied for each finding. Different combinations of detection methods were considered:

  1. Plant species positive with at least two detection methods (among symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between sequencing and pure culture isolation).

  2. The same as point A, but also including microscopy: plant species positive with at least two detection methods (among microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between sequencing and pure culture isolation).

  3. Plant species positive with at least one detection method (among symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation).

  4. Plant species positive with at least one detection method including microscopy (microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation).

  5. All positive plant species reported, regardless of the detection methods (positive records but without the detection method specified, symptom observations, microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing, pure culture isolation).

3. Results

3.1. Results of the literature review

The extensive literature search was conducted on 1 February 2023 on Web of Science and Scopus platforms and 164 references were collected. Duplicates and references already included in EFSA (2023) were removed and 111 references were uploaded in DistillerSR and screened for relevance. Results of the screening process are shown in Figure 1.

Figure 1.

Figure 1

Flow diagram of the screening process

In the first step, i.e. title and abstract screening, 68 references were excluded either because they do not focus on Xylella or Xylella‐associated diseases and/or they are not primary research studies. The selected 43 references were subjected to the second step of the screening process, i.e. the full‐text screening. Twenty‐one references, in which Xylella spp. are studied in association with a host plant, were selected. Twenty‐four Europhyt outbreak notifications 5 containing informative data were also included in the data extraction. Totally, 45 references (listed in Appendix E) were included in this update of the database and from which informative data listed in Table 5 were extracted.

3.2. Update of records already included in the database

Scientific names of plant species, genera and families are reported, as far as possible, according to the taxonomy of the EPPO Global Database (EPPO, 2023) that is constantly being updated. Therefore, changes of scientific names of plant species, genera and families in the Xylella spp. host plant database are related to the update of the taxonomy in the EPPO Global Database.

Records referring to Europhyt outbreak notifications, that may contain incomplete data, are updated whenever additional information (e.g. further identification of the plant species, X. fastidiosa subspecies, ST) become available. The plant species Rhamnus sp. (EPPO code ‘RHASS’) and Spartium sp. (‘SPUSS’) reported in Europhyt outbreak notification n. 1157 (Update 4) have been modified in Rhamnus alaternus (‘RHAAL’) and Spartium junceum (‘SPUJU’), respectively, following communication received by the French NPPO.

3.3. Host plant species of Xylella spp.

The updated numbers of host plant species, genera and families (according to the different categories reported in Section 2.4.2) are reported in Figure 2 and Table 6. The number of plant species raised to 433 according to category A [i.e. plant species positive with at least two detection methods (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between: sequencing, pure culture isolation)] to 690 plant species of category E (i.e. all positives plant species reported, regardless of the detection methods).

Compared to the previous update of the database published in January 2023 (EFSA, 2023), 12 plant species (and two genera) were identified as new hosts of X. fastidiosa. Those plant species and genera were not previously reported in the database. Details of those new hosts of X. fastidiosa are summarised in Table 7.

Nine new plant species have been found to be naturally infected. All of them have were reported infected by X. fastidiosa in Portugal. The subspecies identified in those plants was multiplex (one plant species) or unknown (eight plant species). Artificial infection with X. fastidiosa subsp. fastidiosa has been successful in three new plant species belonging to Salicaceae family.

The overall number of host plant species infected naturally, artificially and in unspecified conditions by the different X. fastidiosa subspecies and according to the different categories is reported in Tables 8, 9 and 10. The plant species behind the numbers shown in those tables are listed in Appendicies A, B and C. In those appendices, the full lists of plant species infected by the different X. fastidiosa subspecies naturally, artificially and in not specified conditions according to the five categories are shown.

The highest number of plant species naturally infected is still recorded for X. fastidiosa subsp. multiplex (213 according to category A, up to 221 for category E), followed by subsp. fastidiosa and subsp. pauca. In artificial infection, 42 plant species (category A and 83 for category E) were successfully infected by X. fastidiosa subsp. fastidiosa. Twenty plant species were artificially infected by subsp. pauca and 19 by subsp. multiplex (category A), up to 33 and 36 for category E (for pauca and multiplex, respectively).

No new host plants were reported for the pathogen species Xylella taiwanensis, that so far was recorded only in Pyrus pyrifolia plants.

3.4. X. fastidiosa sequence types and host plants association

The full list of plant species infected by the different X. fastidiosa sequence types (ST) under natural, artificial and unspecified conditions is reported in Appendix D. For each plant species, the number of records 6 reporting infection by a specific ST is counted. For natural infection, the country where the plant species have been identified is also reported, whereas for artificial and unspecified infection only the total number of records is presented in the appendix.

Totally, 2,493 records reporting information on 265 plant species infected by 89 different STs have been reported in the database. No additional STs have been identified compared to the previous version of the database (EFSA, 2023). Most of the records (1,793) refer to natural infections that were reported in North, Central and South America (United States of America, Mexico, Honduras, Costa Rica, Ecuador, Brazil and Argentina), Asia (Israel) and Europe (Portugal, Spain, France and Italy). The highest number of records for artificial infections belongs to STs of subsp. fastidiosa and pauca, with 256 records registered for both subspecies. While ST1 (subsp. fastidiosa) remains the most used ST in artificial infections, now with 250 records, ST53 (subsp. pauca) is the most reported genotype in natural infections (475).

3.5. Tolerant and resistant responses of plant species

Information on tolerant and resistant response of plant species to X. fastidiosa infection have also been reported in the database. The list of plant genera and species for which tolerant and resistant response has been identified is reported in Table 11. Fifteen additional records that include this information have been inserted in the database compared to the previous version (EFSA, 2023). Information on tolerant/resistant status is available for 73 plant species with a total number of 728 records. The most studied genera remains Vitis, Citrus and Prunus (417, 175 and 70 records, respectively), confirming the important economic value of these crop plant species.

To the aim of this study, different tolerant/resistant response to X. fastidiosa infection has been grouped into 11 categories, as reported in Table 12. Those categories include the plant response/s for which the authors of the publication considered that plant as tolerant/resistant to X. fastidiosa infection. One hundred and thirty‐eight publications, which match 728 records, for the most part (457) reporting artificial infections, return information on tolerance and resistance outcome to X. fastidiosa infection. In 46 publications, the authors consider the plant tolerant or resistant, but without adding further details, whereas in 24 publications (and 243 records), the plant is designated tolerant or resistant based on a lower bacterial population it harbours. In 235 cases, this finding comes from artificial infections. The lack of infection and the lack or reduction of symptoms (78 records in each case) are the two most reported tolerant/resistant outcomes in natural infections.

4. Conclusions

Following a request from the European Commission, EFSA was asked to create, maintain and regularly update a database of host plant species of Xylella spp. This scientific report summarises the most interesting information reported in the new version of the database (version 8).

An extensive literature search was performed including all scientific papers published up to 31 December 2022, as well as additional Europhyt outbreak notifications (last accessed on 1 March 2023).

By these searches, 45 publications were selected and informative data were extracted. Twelve host plant species and two genera were identified as new hosts of X. fastidiosa. Those plant species and genera were not previously reported as hosts of X. fastidiosa. Nine new plant species (Castanea sativa, Genista triacanthos, Grevillea rosmarinifolia, Lonicera periclymenum, Mentha suaveolens, Platanus × hispanica, Pyracantha coccinea, Quercus pyrenaica, Ulex micranthus) have been found to be naturally infected by X. fastidiosa subspecies multiplex or unknown (i.e. not reported) in Portugal. Three new plant species (Populus tremula, Populus × canescens, Salix caprea) were successfully artificially infected by X. fastidiosa subspecies fastidiosa. No new data was retrieved for X. taiwanensis.

Compared to the previous version of the database (EFSA, 2023), no additional STs have been identified worldwide. Information on tolerant/resistant status were reported for 73 plant species in 138 publications, with a total number of 728 records. The most studied and reported plant taxa are still the economically important genera Citrus, Prunus and Vitis.

The overall number of Xylella spp. host plants reaches now 433 plant species, 197 genera and 68 families for category A [i.e. plant species positive with at least two detection methods (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between sequencing and pure culture isolation)], till 690 plant species, 303 genera and 88 families for category E (i.e. all positives plant species reported, regardless of the detection methods).

A further update of the EFSA database on Xylella spp. host plants is planned for January 2024 with the aim to provide useful information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp.

Data are available as interactive reports on the Microstrategy platform at the following link: https://www.efsa.europa.eu/en/microstrategy/xylella

Raw data and related metadata are published in Zenodo in the EFSA Knowledge Junction community, this report refers to version 8 (https://doi.org/10.5281/zenodo.1339343).

Appendix A – Host plant species naturally infected

1.

List of host plant species, naturally infected, of X. fastidiosa subsp. unknown (i.e. not reported in the publication), subsp. fastidiosa, subsp. fastidiosa/sandyi, subsp. morus, subsp. multiplex, subsp. pauca, subsp. sandyi, subsp. tashke and X. taiwanensis according to categories A, B, C, D, E (as reported in Section 2.4.2):

  1. Plant species positive with at least two detection methods (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between: sequencing, pure culture isolation).

  2. The same as point A, but also including microscopy: plant species positive with at least two detection methods (among: microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between: sequencing, pure culture isolation).

  3. Plant species positive with at least one detection method (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation).

  4. Plant species positive with at least one detection method including microscopy (microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation).

  5. All positives plant species reported, regardless of the detection methods (positive records but without the detection method specified, symptom observations, microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing, pure culture isolation).
