花椒SABATH基因家族鉴定及其在盐胁迫下的表达模式分析
Genome-Wide Identification and Expression Profiling of SABATH Gene Family in Zanthoxylum bungeanum in Response to Salt Stress
摘要
Abstract
The SABATH gene family plays a crucial role in plant growth and stress response by promoting the methylation of plant hormones and other small molecules.In this study,we identified 68 ZbSABATH genes from the genome of Zanthoxylum bungeanum(Zb).Phylogenetic tree and genetic structure analyses revealed that the ZbSABATH genes were clustered into five evolutionarily conserved subgroups.Further-more,synteny analysis showed that 46(68％of the total)genes may undergo the duplication events by tandem or fragment repeats to enlarge the genome during evolution.The promoter sequences of the Zb-SABATH genes contain numerous cis-acting elements,suggesting that the gene functions are related to plant hormones,stress response,and growth and development.The expression profiling under salt stress treatments indicated that 39 genes were clustered into four groups due to their distinct expression patterns.Notably,higher expression levels of ZbSABATH55,ZbSABATH58,ZbSABATH14,and ZbSABATH22 under salt treatments suggested their critical roles in responding to salt stress.This study provides a theo-retical basis for the further study of functions of the ZbSABATH gene family.关键词
