Previous studies have revealed the involvement of WRKY members in plant defense against V. dahliae, but the underlying mechanisms involved need to be further elucidated. Here, we demonstrated that Gossypium hirsutum WRKY DNA-binding protein 33 (GhWRKY33) functions as a negative regulator in plant defense against V. dahliae. GhWRKY33 expression is induced rapidly by V. dahliae and methyl jasmonate, and overexpression of GhWRKY33 reduces plant tolerance to V. dahliae in Arabidopsis. Quantitative RT-PCR analysis revealed that expression of several JA-associated genes was significantly repressed in GhWRKY33 overexpressing transgenic plants. Yeast one-hybrid analysis revealed that GhWRKY33 may repress the transcription of both AtERF1 and GhERF2 through its binding to their promoters. Protein–protein interaction analysis suggested that GhWRKY33 interacts with G. hirsutum JASMONATE ZIM-domain protein 3 (GhJAZ3). Similarly, overexpression of GhJAZ3 also decreases plant tolerance to V. dahliae. Furthermore, GhJAZ3 acts synergistically with GhWRKY33 to suppress both AtERF1 and GhERF2 expression. Our results imply that GhWRKY33 may negatively regulate plant tolerance to V. dahliae via the JA-mediated signaling pathway.</div>","PeriodicalId":20224,"journal":{"name":"Plant Diversity","volume":"45 3","pages":"Pages 337-346"},"PeriodicalIF":4.8,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49791587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study shows that neither model parameter exhibits phylogenetic signals (Pagel's λ and Blomberg's K both approach zero). This is the case regardless of whether all tree species in our data set were analyzed as a whole or tree species in different taxonomic groups (gymnosperm and angiosperm), leaf duration groups (evergreen and deciduous), or ecological groups (tropical, temperate and boreal) were analyzed separately.

Despite their acknowledged importance, little attention has been paid to the study of orchids distributed in northern territories. In this study, we determined the syntaxonomical diversity and ecological parameters of orchid habitats in two of Europe's largest protected areas, the Pechoro-Ilychsky Reserve and the Yugyd Va National Park (northeastern European Russia), and then compared our findings to those in other parts of orchid distribution ranges. For this purpose, we studied 345 descriptions of plant communities (releves) containing species from Orchidaceae and defined habitat parameters using Ellenberg indicator values with the community weight mean approach, nonmetric multidimensional scaling (NMS), and relative niche width. We found that orchids were distributed in eight habitat types and 97 plant associations. The largest number of orchid species is found in forest communities. Half of the orchid species under study occur in the mires and rock habitats with open vegetation. Several orchids consistently occur in areas disturbed by human activity. In addition, our study indicates that the main drivers of orchid distribution across the vegetation types are light and soil nitrogen. Our analysis of the ecological parameters of orchid habitats indicates that some orchid species can be classified as habitat specialists that are confined to a relatively narrow ecological niche in the Urals (e.g., Goodyera repens, Cypripedium guttatum and Dactylorhiza maculata).

The Fargesia bamboos are important components of the subalpine forest ecosystems that provide food and habitat for many endangered animals, including the giant panda. However, species-level identification of Fargesia is difficult. Moreover, the rapid radiation and slow molecular evolutionary rate of Fargesia pose a significant challenge to using DNA barcoding with standard plant barcodes (rbcL, matK, and ITS) in bamboos. With progress in the sequencing technologies, complete plastid genomes (plastomes) and nuclear ribosomal DNA (nrDNA) sequences have been proposed as organelle barcodes for species identification; however, these have not been tested in bamboos. We collected 196 individuals representing 62 species of Fargesia to comprehensively evaluate the discriminatory power of plastomes and nrDNA sequences compared to standard barcodes. Our analysis indicates that complete plastomes have substantially higher discriminatory power (28.6%) than standard barcodes (5.7%), whereas nrDNA sequences show a moderate improvement (65.4%) compared to ITS (47.2%). We also found that nuclear markers performed better than plastid markers, and ITS alone had higher discriminatory power than complete plastomes. The study also demonstrated that plastomes and nrDNA sequences can contribute to intrageneric phylogenetic resolution in Fargesia. However, neither of these sequences were able to discriminate all the sampled species, and therefore, more nuclear markers need to be identified.</div>","PeriodicalId":20224,"journal":{"name":"Plant Diversity","volume":"45 2","pages":"Pages 147-155"},"PeriodicalIF":4.8,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49795992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
