- Abstract
SROs (Similar to rcd one) are plant-specific gene families. In this study, 9 CsSRO gene family members were identified from tea tree genome by bioinformatics method and named as CsRCD1--4 and CsSRO1--5 respectively. All coding proteins of the 9 CsSRO genes have characteristic structural domains PARP and RST, and have similar conserved motifs. The CsSRO genes were divided into 3 groups based on phylogenetic tree analysis, with the group Ι containing CsRCD1--4, the group Ⅱ containing CsSRO1, CsSRO2 and the group Ⅲ containing CsSRO3--5. Gene structure analysis shows that this gene family contained 4 to 9 exons. Analysis of transcriptome data from 8 tea tree tissues shows that CsRCD1/CsRCD3/CsRCD4 might play an important role in different developmental stages of tea plants. Most CsSRO genes were highly expressed in roots and mature leaves. Upstream promoter region analysis found a large number of cis-acting elements closely related to plant development, hormones and stress response. Further expression analysis shows that 9 CsSRO genes were induced by drought and abscission acid treatments, suggesting CsSRO genes may be closely related to drought resistance.
