“…OsTAC1 controls tiller angle in rice [ 3 ], and changes in TAC1 have since been linked to upright tiller or branch angles in other plant species, including Arabidopsis [ 14 ], rice [ 15 ], poplar [ 4 ], peach [ 16 , 17 ], and apple [ 18 ]. OsTAC4 participates in the regulation of rice tiller angle, and influences the endogenous auxin content, ultimately leading to reduced gravitropism and a tiller-spreading phenotype [ 19 , 20 ].…”

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.

Background: The tea plant (Camellia sinensis) architecture not only affects tea quality and yield, but also influences the efficiency of automatic pruning of tea plants. However, the molecular mechanism of branch angle that important aspect of plant architecture is poorly understood in tea plant. Results: In the present study, three CsLAZY genes were identified from the tea plant genome data through sequence homology. Phylogenetic tree displayed that the CsLAZY genes have high sequence similarity with LAZY genes from other plant species, especially those in woody plants. The expression patterns of the three CsLAZYs in eight tissues were surveyed, and we further verified the expression levels of the key CsLAZY1 transcript in different tissues among eight tea cultivars, demonstrating that CsLAZY1 was highly expressed in stem. Subcellular localization analysis showed that CsLAZY1 protein was localized in the plasma membrane. Remarkably, CsLAZY1 was transferred into Arabidopsis thaliana to investigate its potential role in regulating shoot development, demonstrating that the over-expressed plants responded more effectively than the wild types under gravity processing in light and dark. The results indicate that CsLAZY1 plays an important role in regulating shoot gravitropism in tea plant.Conclusions: The results provide evidence that CsLAZY1 may plays a critical role in regulating shoot gravitropism, and further affecting stem branch angle in tea plant.
