Arabidopsis (Arabidopsis thaliana) MAP KINASE (MPK) proteins can function in multiple kinase cascades and physiological processes. For instance, MPK4 functions regulating development as well plant defense by participating two independent cascades: the MEKK1-MKK1/MKK2-MPK4 cascade promotes basal resistance against pathogens is guarded NB-LRR protein SUMM2, whereas ANPs-MKK6-MPK4 plays an essential role cytokinesis. Here, we report a novel for MKK6 immune responses. We found that similarly to...
Metacaspases (MCs) are structural homologs of mammalian caspases found in plants, fungi, and protozoa. Type-I MCs carry an N-terminal prodomain, the function which is unclear. Through genetic analysis Arabidopsis mc2-1, a T-DNA insertion mutant MC2, we demonstrated that prodomain metacaspase 2 (MC2) promotes immune signaling mediated by pattern-recognition receptors (PRRs). In responses constitutively activated. The receptor-like kinases (RLKs) BAK1/BKK1 SOBIR1 required for autoimmune...
Arabidopsis mitogen-activated protein (MAP) kinase 6 (MKK6) has previously been shown to play important roles in plant immunity and cytokinesis. Here we report that it is also involved the negative regulation of anthocyanin biosynthesis Arabidopsis. Elevated levels are observed mkk6 knock out mutant plants. RNA-sequencing analysis revealed expression level MYB75 (Myb transcription factor 75), which encodes a key positive regulator biosynthesis, up-regulated plants, suggesting increased...
