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.
