Application of GRMZM2G417164 in stomata development

The invention relates to the technical field of maize gene engineering, in particular to application of a maize GRMZM2G417164 gene in adjustment of stomata development. The maize GRMZM2G417164, serving as a transcription factor, regulates some genes associated with the stomata development, and adjusts an associated process of maize stomata development. A series of experiments prove that a proteincoded by the GRMZM2G417164 gene controls transfer of a signal from a guard mother cell to a subsidiary mother cell and a final longitudinal division of the guard mother cell to form a guard cell. After the gene is mutant, a plant cannot form a normal guard cell and a normal subsidiary cell. Therefore, deep research and analysis on GRMZM2G417164 gene functions has an important theoretical significance and a practical application value for exploring a maize stomata development mechanism and improving maize resistance.
