ZmMKK1, a novel group A mitogen-activated protein kinase kinase gene in maize, conferred chilling stress tolerance and was involved in pathogen defense in transgenic tobacco.

Abstract excerpt

As an important intracellular signaling module, the mitogen-activated protein kinase (MAPK) cascades have been previously implicated in signal transduction during plants responsing to various environmental stresses as well as pathogen attack. The mitogen-activated protein kinase kinase acts as the convergent point of MAPK cascades during a variety of stress signaling. In this study, a novel MAPKK gene, ZmMKK1, in...
