番茄BURP结构域基因家族全基因组鉴定及表达分析OA北大核心CSTPCD

BURP domain proteins are unique to plants and play different roles in plant stress,growth and development.To identify BURP domain genes(SlBURP)and their expression in tomato,a total of 12 SlBURP genes were identified in tomato.The phylogenetic analysis classified 12 SlBURP genes into 7 subfamilies,which had significant differences in conserved motifs and gene structures among the different subfamilies.The extensive presence of stress,growth,hormone,and light-responsive elements in the promoter sequences of SlBURPs suggested that this family had crucial role in abiotic stress.Covariance analysis indicated that members of tomato and Arabidopsis BURP gene families were derived from the same ancestor.The RT-qPCR results showed that the expression levels of SlBURP6,SlBURP7,SlBURP8 and SlBURP12 were abundantly in leaves;the expression levels of SlBURP2,SlBURP6,SlBURP7 and SlBURP8 increased after salt treatment;the expression levels of SlBURP5,SlBURP8,SlBURP9 and SlBURP12 increased during fruit development under plant regulator treatment.In summary,SlBURP genes played important roles in both stress and growth of tomato.
