Abstract
Stomata,the specialized structure in plant epidermis,play an important role in transpiration and gas exchange between plants and the environment.Arabidopsis YDA(AtYDA),a kinase(MAPKKK4) in MAPK cascade,negatively regulates stomatal development.The loss-of-function mutation of AtYDA leads to significant increase in the production of leaf stomata,whereas the expression of constitutively active form of AtYDA(ΔN-YDA) results in repressed stomatal formation in leaf epidermis.In this study,we cloned two orthologs of AtYDA in rice,namely OsYDA1 and OsYDA2.Overexpression of either of these genes in Arabidopsis resulted in a significant decrease in stomatal density and water-loss rate.Likewise,the transgenic Arabidopsis plants expressing ΔN-OsYDA1 and ΔN-OsYDA2 displayed a dramatically reduced stomatal index phenotype.Taken together,these results demonstrate a conserved role for OsYDA and AtYDA in regulating stomatal development.
