Abstract:
Expansin, a vital component of plant cell wall, involves in various physiological activities of plants. In the present study, RNA interference (RNAi) vector of rice expansin gene OsEXPB7 was constructed and introduced into rice cultivar Nipponbare by Agrobacterium-mediated transformation. The quantitative PCR analysis revealed the suppression of OsEXPB7 in transgenic lines. Compared with wild-type, the OsEXPB7 down-regulation primary generation (T0) transgenic plants exhibited a shorter plant height and smaller size in grains. T1 transgenic seedlings showed retardant growth and drooping leaf phenotype. The growth defect could be partially compensated with gibberellin (GA) treatment. Under flooded conditions, the transgenic seedlings showed slower stem elongations than that of wild type plants. It suggested that OsEXPB7, probably regulated by GA, might play an role in influencing rice development through adjusting the extension of cell wall. Fig 9, Tab 3, Ref 30
