Fig. 6From: Coordination between GROWTH-REGULATING FACTOR1 and GRF-INTERACTING FACTOR1 plays a key role in regulating leaf growth in riceModel for the functions of OsGRF1 and OsGIF1 in regulating growth. ABA, OsmiR396, and various stresses such as pathogens, ultraviolet (UV), drought, salt, etc., can downregulate the expression of OsGRF1, which is usually in a lower level, while gibberellin (GA) upregulates it. The interaction between OsGRF1 and OsGIF1 is necessary in promoting leaf growth via promoting the expression of cell-cycle-related genes. OsGIF1, which expresses in a higher level, may also work with other factor(s) to regulate other aspects of growthBack to article page
