Dataset on UAV RGB videos acquired over a vineyard property of Bodegas Terras Gauda at an early stage of Botrytis cinerea infection in 2021
<p>The videos were collected in a vineyard owned by Bodegas Terras Gauda, in June 2021. The videos were collected with a DJI Matrice 210 RTK UAV, which had a DJI Zenmuse X5S sensor onboard. A total of 4 rows were recorded with side videos. The flights were carried out on a sunny day with wind velocity lower than 0.5 m/s. Annotations of the grape clusters in the MOTS style are provided. </p>

Data for: Annotation resource for seven Botrytis cinerea isolates from greenhouses in Michigan
<p>Fungal plant pathogen <em>Botrytis cinerea</em> affects a variety of important agricultural systems, including greenhouse production. Seven isolates of B. cinerea were whole-genome sequenced to provide an additional resource providing insight regarding host specificity, fungicide resistance, and geographic relatedness in pathogen populations. Fasta files of each genome assembly, raw reads (fastq), and more information can be found under NCBI BioProject PRJNA984325. Annotation data is included here.</p>

Colonization of Solanum melongena and Vitis vinifera Plants by Botrytis cinerea Is Strongly Reduced by the Exogenous Application of Tomato Systemin
<p>Plant defense peptides are able to control immune barriers and represent a potential novel<br> resource for crop protection. One of the best-characterized plant peptides is tomato Systemin (Sys)<br> an octadecapeptide synthesized as part of a larger precursor protein. Upon pest attack, Sys interacts<br> with a leucine-rich repeat receptor kinase, systemin receptor SYR, activating a complex intracellular<br> signaling pathway that leads to the wound response. Here, we demonstrated, for the first time,<br> that the direct delivery of the peptide to Solanum melongena and Vitis vinifera plants protects from the<br> agent of Grey mould (Botrytis cinerea). The observed disease tolerance is associated with the increase<br> of total soluble phenolic content, the activation of antioxidant enzymes, and the up-regulation of<br> defense-related genes in plants treated with the peptide. Our results suggest that in treated plants,<br> the biotic defense system is triggered by the Sys signaling pathway as a consequence of Sys interaction<br> with a SYR-like receptor recently found in several plant species, including those under investigation.<br> We propose that this biotechnological use of Sys, promoting defense responses against invaders,<br> represents a useful tool to integrate into pest management programs for the development of novel<br> strategies of crop protection.</p>
Data from: The "Dr Jekyll and Mr Hyde fungus": noble rot versus gray mold symptoms of Botrytis cinerea on grapes
Many cryptic species have recently been discovered in fungi, especially in fungal plant pathogens. Cryptic fungal species co-occurring in sympatry may occupy slightly different ecological niches, for example infecting the same crop plant but specialized on different organs or having different phenologies. Identifying cryptic species in fungal pathogens of crops and determining their ecological specialization is therefore crucial for disease management. Here we addressed this question in the ascomycete Botrytis cinerea, the agent of grey mold on a wide range of plants. On grape, B. cinerea causes severe damages but is also responsible for noble rot used for processing sweet wines. We used microsatellite genotyping and clustering methods to elucidate whether isolates sampled on grey mold vs. noble rot symptoms in three French regions belong to genetically differentiated populations. The inferred population structure matched geography rather than the type of symptom. Noble rot symptoms therefore do not seem caused by a specific B. cinerea population but instead seem to depend essentially on microclimatic conditions, which has applied consequences for the production of sweet wines.

Data from: Tomato Sl3-MMP, a member of the Matrix metalloproteinase family, is required for disease resistance against Botrytis cinerea and Pseudomonas syringae pv. tomato DC3000
Background: Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases. MMPs have been characterized in detail in mammals and shown to play key roles in many physiological and pathological processes. Although MMPs in some plant species have been identified, the function of MMPs in biotic stress responses remains elusive. Results: A total of five MMP genes were identified in tomato genome. qRT-PCR analysis revealed that expression of Sl-MMP genes was induced with distinct patterns by infection of Botrytis cinerea and Pseudomonas syringae pv. tomato (Pst) DC3000 and by treatment with defense-related hormones such as salicylic acid, jasmonic acid and ethylene precursor 1-amino cyclopropane-1-carboxylic acid. Virus-induced gene silencing (VIGS)-based knockdown of individual Sl-MMPs and disease assays indicated that silencing of Sl3-MMP resulted in reduced resistance to B. cinerea and Pst DC3000, whereas silencing of other four Sl-MMPs did not affect the disease resistance against these two pathogens. The Sl3-MMP-silenced tomato plants responded with increased accumulation of reactive oxygen species and alerted expression of defense genes after infection of B. cinerea. Transient expression of Sl3-MMP in leaves of Nicotiana benthamiana led to an enhanced resistance to B. cinerea and upregulated expression of defense-related genes. Biochemical assays revealed that the recombinant mature Sl3-MMP protein had proteolytic activities in vitro with distinct preferences for specificity of cleavage sites. The Sl3-MMP protein was targeted onto the plasma membrane of plant cells when transiently expressed in onion epidermal cells. Conclusion: VIGS-based knockdown of Sl3-MMP expression in tomato and gain-of-function transient expression of Sl3-MMP in N. benthamiana demonstrate that Sl3-MMP functions as a positive regulator of defense response against B. cinerea and Pst DC3000.
