A fungal-responsive MAPK cascade regulates phytoalexin biosynthesis in Arabidopsis

摘要

Plant recognition of pathogens leads to rapid activation of MPK3 and MPK6, two Arabidopsis mitogen-activated protein kinases (MAPKs), and their orthologs in other species. Here, we report that synthesis of camalexin, the major phytoalexin in Arabidopsis,
