Genome-wide Identification and Analysis of LBD Gene Family in Salvia miltiorrhiza
The members of the later organ boundaries domain(LBD)family of Salvia miltiorrhia LBD(SmLBDs)were systematically screened and identified using bioinformatics methods,and their expression patterns were analyzed under high temperature stress(37 ℃).The results showed that there were 52 SmLBDs in Salvia miltiorrhiza,which could be divided into 7 groups:groupⅠ,groupⅡ,groupⅢ,groupⅣ,groupⅤ,groupⅥ and groupⅦ.The amino acid residues of the 52 proteins encoded by SmLBDs ranged from 103 to 298,the relative molecular weights ranged from 11.29 to 31.72 kDa,and the isoelectric points were distributed from 4.44 to 10.71.All of 52 SmLBDs were hydrophilic proteins,and most of them were located in the nucleus.In addition,the expression patterns of 52 SmLBDs under high temperature stress(37 ℃)were analyzed,and the expression levels of 7 genes were decreased,and 37 genes were increased,especially the expression level of SmLBD8,SmLBD40 and SmLBD44 was significantly increased,indicating that these genes may be related to the heat resistance of Salvia miltiorrhiza.
