In plants, mitogen activated protein kinases (MPKs) are involved in various signaling pathways that lead to biotic and abiotic responses as well as that regulate developmental processes. Among them, MPK6 and its closely related homologue, MPK3, act redundantly and are known to be involved in asymmetric cell divisions of meristemoid mother cells in stomata development and of zygotes in Arabidopsis . Loss-of-function mutants of GLE4 / OsMPK6 , which is an orthologue of MPK6 in rice, showed a defect in polarity establishment in early stage of embryogenesis...
