“…Erratic rainfall can cause imbalances in the soil moisture, vegetation, and microclimate of forest areas [63], and extreme rainfall can accelerate soil erosion. Furthermore, the incidence of disease outbreaks is accumulated each year due to climate change [64]. These factors pose significant threats to the survival of C. japonicum.…”

Cypripedium japonicum is an endangered terrestrial orchid species with high ornamental and medicinal value. As global warming continues to intensify, the survival of C. japonicum will be further challenged. Understanding the impact of climate change on its potential distribution is of great significance to conserve this species. In this study, we established an ensemble species distribution model based on occurrence records of C. japonicum and 13 environmental variables to predict its potential distribution under current and future climatic conditions. The results show that the true skill statistic (TSS), Cohen’s kappa statistic (Kappa), and the area under the receiver operating characteristic curve (AUC) values of the ensemble model were 0.968, 0.906, and 0.995, respectively, providing more robust predictions. The key environmental variables affecting the distribution of C. japonicum were the precipitation in the warmest quarter (Bio18) and the mean temperature in the driest quarter (Bio9). Under future climatic conditions, the total suitable habitat of C. japonicum will increase slightly and tend to migrate northwestward, but the highly suitable areas will be severely lost. By 2070, the loss of its highly suitable habitat area will reach 57.69–72.24% under representative concentration pathway (RCP) 4.5 and 8.5 respectively, and the highly suitable habitats in Zhejiang and Anhui will almost disappear. It is noteworthy that the highly suitable habitat of C. japonicum has never crossed the Qinba mountainous area during the migration process of the suitable habitat to the northwest. Meanwhile, as the best-preserved area of highly suitable habitat for C. japonicum in the future, the Qinba mountainous area is of great significance to protect the wild germplasm resources of C. japonicum. In addition, we found that most of the changes predicted for 2070 will already be seen in 2050; the problem of climate change may be more urgent than it is believed.

“…This period interrupted long-term Cenozoic cooling and is markedly different from the period immediately following, which was characterized by cool temperatures and much lower sea levels ( Methner et al 2020 ). In our study, we were not able to estimate the ancestral geographical distribution of Botrytis as its members co-exist with agricultural crops all around the world (see multiple reports of various Botrytis species in different countries; Zhang et al 2009 ; Saito et al 2014 ; Li et al 2015 ; Erper et al 2019 ; Chen et al 2020 ; Jeon et al 2020 ; Mansouripour and Holmes 2020 ; Meeboon and Shinohara 2020 ; Moparthi et al 2020 ). Therefore, it is not possible to precisely pinpoint ancient species radiations with respect to particular geographical events as was done, for instance, for the Chinese medicinal fungus Sanghuangporus ( Zhu et al 2019 ).…”

Tests based on the dN/dS statistic are used to identify positive selection of non-synonymous polymorphisms. Using these tests on alignments of all orthologues from related species can provide insights into which gene categories have been most frequently positively selected. However, longer alignments have more power to detect positive selection, creating a detection bias that could create misleading results from functional enrichment tests. Most studies of positive selection in plant pathogens focus on genes with specific virulence functions, with little emphasis on broader molecular processes. Furthermore, no studies in plant pathogens have accounted for detection bias due to alignment length when performing functional enrichment tests. To address these research gaps, we analyse 12 genomes of the phytopathogenic fungal genus Botrytis, including two sequenced in this study. To establish a temporal context, we estimated fossil-calibrated divergence times for the genus. We find that Botrytis likely originated 16-18 million years ago in the Miocene and underwent continuous radiation ending in the Pliocene. An untargeted scan of Botrytis single copy orthologues for positive selection with three different statistical tests uncovered evidence for positive selection among proteases, signalling proteins, CAZymes and secreted proteins. There was also a strong over-representation of transcription factors among positively selected genes. This over-representation was still apparent after two complementary controls for detection bias due to sequence length. Positively selected sites were depleted within DNA binding domains, suggesting changes in transcriptional responses to internal and external cues or protein-protein interactions have undergone positive selection more frequently than changes in promoter fidelity.

“…To extend this analysis to 2023, we used a combination of the search terms “ Botrytis cinerea ” and “first report” in Google Scholar and PubMed to identify reports of B. cinerea on new hosts. From this survey, we identified 41 new plant species (including 21 new genera) as hosts of this pathogen (Aktaruzzaman et al., 2017 , 2022 ; Azevedo et al., 2020 ; Cao et al., 2020 ; Chen et al., 2017 , 2019 , 2020 , 2021 ; Dumin et al., 2020 ; Fekrikohan et al., 2022 ; Feres et al., 2018 ; Freitas & Pereira, 2022 ; Fu et al., 2018 ; Garibaldi et al., 2016 , 2017 , 2022 ; Guo et al., 2021 ; Isidoro‐Gonzales et al., 2023 ; Jeon et al., 2020 ; Jin et al., 2022 ; Li et al., 2016 , 2022 , 2023 ; Liu et al., 2017 ; Paula et al., 2018 ; Plaza et al., 2018 ; Reboledo et al., 2021 ; Silva, Corrêa, et al., 2016 ; Silva, Lisboa, et al., 2016 ; Song et al., 2017 ; Wang, Jin, et al., 2017 ; Wang, Jing, et al., 2017 ; Wang, Yang, & Bai, 2017 ; Xue et al., 2016 , 2017 ; Yang, Chen, et al., 2020 ; Yang et al., 2020a , 2020b ; You et al., 2020 ).…”

Botrytis cinerea Pers. Fr. (teleomorph: Botryotinia fuckeliana) is a necrotrophic fungal pathogen that attacks a wide range of plants. This updated pathogen profile explores the extensive genetic diversity of B. cinerea, highlights the progress in genome sequencing, and provides current knowledge of genetic and molecular mechanisms employed by the fungus to attack its hosts. In addition, we also discuss recent innovative strategies to combat B. cinerea.TaxonomyKingdom: Fungi, phylum: Ascomycota, subphylum: Pezizomycotina, class: Leotiomycetes, order: Helotiales, family: Sclerotiniaceae, genus: Botrytis, species: cinerea.Host rangeB. cinerea infects almost all of the plant groups (angiosperms, gymnosperms, pteridophytes, and bryophytes). To date, 1606 plant species have been identified as hosts of B. cinerea.Genetic diversityThis polyphagous necrotroph has extensive genetic diversity at all population levels shaped by climate, geography, and plant host variation.PathogenicityGenetic architecture of virulence and host specificity is polygenic using multiple weapons to target hosts, including secretory proteins, complex signal transduction pathways, metabolites, and mobile small RNA.Disease control strategiesEfforts to control B. cinerea, being a high‐diversity generalist pathogen, are complicated. However, integrated disease management strategies that combine cultural practices, chemical and biological controls, and the use of appropriate crop varieties will lessen yield losses. Recently, studies conducted worldwide have explored the potential of small RNA as an efficient and environmentally friendly approach for combating grey mould. However, additional research is necessary, especially on risk assessment and regulatory frameworks, to fully harness the potential of this technology.
