Background  Branch angle is a pivotal component of tea plant architecture. Tea plant architecture not only affects tea quality and yield but also influences the efficiency of automatic tea plant pruning. However, the molecular mechanism controlling the branch angle, which is an important aspect of plant architecture, is poorly understood in tea plants.    Results  In the present study, three  CsLAZY  genes were identified from tea plant genome data through sequence homology analysis. Phylogenetic tree displayed that the  CsLAZY  genes had high sequence similarity with  LAZY  genes from other plant species, especially those in woody plants. The expression patterns of the three  CsLAZYs  were surveyed in eight tissues. We further verified the expression levels of the key  CsLAZY1  transcript in different tissues among eight tea cultivars and found that  CsLAZY1  was highly expressed in stem. Subcellular localization analysis showed that the CsLAZY1 protein was localized in the plasma membrane.  CsLAZY1  was transferred into  Arabidopsis thaliana  to investigate its potential role in regulating shoot development. Remarkably, the  CsLAZY1  overexpressed plants responded more effectively than the wild-type plants to a gravity inversion treatment under light and dark conditions. The results indicate that  CsLAZY1  plays an important role in regulating shoot gravitropism in tea plants.    Conclusions  The results provide important evidence for understanding the functions of  CsLAZY1  in regulating shoot gravitropism and influencing the stem branch angle in tea plants. This report identifies  CsLAZY1  as a promising gene resource for the improvement of tea plant architecture.
