茶树GASA基因家族的生物信息学分析
Bioinformatics analysis of GASA gene family in tea tree
摘要
Abstract
GASA (Gibberellic acid-stimulated in arabidopsis) is a group of plant-specific transcription factors related to plant growth,development and stress response. Using a bioinformatics approach to explore the whole genome sequence of tea tree,29 GASA genes were identified in the tea tree genome and numbered according to the chromosomal arrangement as CsGASA1-CsGASA29. Phylogenetic analysis,conserved motif analysis,collinearity analysis,cis-acting element analysis and expression analysis were performed to show that CsGASA is classified into three subfamilies and encodes 64-218 amino acids;a total of six conserved motifs are identified;four CsGASA are originated from segmental duplication events,and five CsGASA from tandem duplication events;53％ of the cis-acting elements are the key links in plant environmental response;some of CsGASA gene expression are response to drought,low temperature and salt stresses,and CsGASA3 gene is highly expressed only in roots.关键词
