Abstract excerpt

Protein phosphorylation has pivotal roles in ABA and dehydration stress signaling in higher plants. However, little is known about MITOGEN-ACTIVATED PROTEIN KINASE KINASE KINASE KINASE (MAP4K) in dehydration tolerance. Here, we report MAP4K1 and MAP4K2 are involved in dehydration tolerance. Mutations in MAP4K1 or MAP4K2 did not show obvious phenotype whereas map4k1 map4k2 double mutant exhibited the dwarf...
