甘蓝型油菜OSCA家族基因鉴定及其在非生物胁迫下的表达分析
Identification of the OSCA family genes and expression analysis under abi-otic stress in Brassica napus
摘要
Abstract
Hyperosmolarity-gate calcium-permeable channels(OSCA)play a significant role in the response of plants to abiotic stress.To elucidate the response mechanism of BnaOSCA family members under abiotic stress,this study identified 37 OSCA genes from the whole genome of Brassica napus and analyzed the gene structure,protein properties,and expression patterns.The results showed that these 37 OSCA genes were unevenly distributed on 13 chromosomes and could be divided into three subfamilies.Members of the same subfamily had conserved gene structures and conserved motifs,and the promoter regions of BnaOSCA family genes contained a variety of cis-acting elements related to abiotic stress and hor-mone responses.The collinearity analysis results indicated that gene loss occurred during the evolution of the BnaOSCA family genes,and gene family expansion also took place.Under salt and drought stress,the relative expression levels of BnaOSCA family genes varied,indicating that BnaOSCA family genes played different regulatory roles in the response to abiotic stress.This study provides a basis for further perfecting the regulatory network of BnaOSCA family genes.关键词
