Genome-wide identification of the tea plant bHLH transcription factor family and discovery of candidate regulators of trichome formation
Abstract Leaf trichomes play vital roles in plant resistance and the quality of tea. Basic helix-loop-helix (bHLH) transcription factors (TFs) play an important role in regulating plant development and growth. In this study, a total of 134 CsbHLH proteins were identified in the Camellia sinensis var...
