Overexpression of , an F-box gene from , increased the plant branching in tobacco and rice.

Tea plant ( [.]) is one of the most important crops in China, and tea branch is an important agronomic trait that determines the yield of tea plant. In previous work focused on GWAS that detecting GWAS signals related to plant architecture through whole genome re-sequencing of ancient tea plants, a gene locus TEA 029928 significantly related to plant type was found. Sequence alignment results showed that this gene belonged to the F-box family. We named it . CsBRC-GFP fusion proteins were mainly localized in the plasma membrane. By comparing the phenotypes of transgenic tobacco and WT tobacco, it was found that the number of branches of transgenic tobacco was significantly higher than that of wild-type tobacco. Through RNA-seq analysis, it was found that affects the branching development of plants by regulating the expression of genes related to brassinosteroid synthesis pathway in plants. In addition, overexpression of in rice could increase tiller number, grain length and width, and 1,000-grain weight.
