YUCCA (YUC) proteins catalyse the rate-limiting step for endogenous auxin biosynthesis.

Phylogenetic tree showed that all BnYUC members were divided into 2 evolutionary clusters, including 7 sub-groups. Among the sub-groups, CladeⅠ-C consisted 20 members, evolved independently from <em>Arabidopsis thaliana</em>, and motif 10 was unique. Genomic collinearity analysis showed that <em>YUC</em> collinear gene pairs widely existed in <em>Brassica</em> species, indicating that this family has a high retention rate in the evolution. Expression profile suggested that the BnYUC family genes tended to express in specific growth/development stages as well as suffering stress/hormone treatments. It suggested that dominant expression of specific members existed with each development stage or treatment, indicating that each BnYUC might have a clear division of work, and play a given biological function. This work was expected to build a basis for further study of the involvement of BnYUC in growth, development and stress response.</p></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"7 3","pages":"Pages 103-111"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096242822000252/pdfft?md5=ed96d9e27dce0f6fd72baa7474673abc&pid=1-s2.0-S2096242822000252-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41729279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The result revealed that, about 252.1 ha (0.4%) and 113.1 ha (0.2%) were highly suitable for sesame and groundnut respectively. Result showed that most parts of the study area were moderately suitable for sesame and groundnut productions. Specially, the central and western parts of the study area were highly suitable and moderately suitable for sesame production.
