Members of the GRAS gene family encode transcriptional regulators that have diverse functions in plant growth and development such as gibberellin signal transduction, root radial patterning, axillary meristem formation, phytochrome A signal transduction, and gametogenesis. We identified 142 GRAS genes, including JTY(49), LWM(47) and F106(46),all genes were divided into 11 subfamilies.
