Abstract excerpt

Mitogen-activated protein kinase (MAPK) cascades regulate growth, development, stress responses, and immunity in plants by transmitting signals from upstream regulators to downstream components. In this study, we identify a MAPK cascade composed of MAPK kinase kinase 19 (MKKK19), three MAPK kinases (MKK3/MKK5/MKK9), and MAPK 6 (or MPK6) that is involved in Arabidopsis leaf senescence. The kinase oxidative...
