Expression analysis of Arabidopsis mpk11 mutant treated with flg22

Project description:Arabidopsis MPK11 is activated and plays a role in the flg22 sensing. Mitogen-activated protein kinases (MAPKs) mediate cellular signal transduction during stress responses, as well as diverse growth and developmental steps in eukaryotes. Pathogen infection or treatment with conserved pathogen-associated molecular patterns (PAMPs) such as the bacterial flagellin-derived flg22 peptide are known to activate three Arabidopsis thaliana MAPKs, MPK3, MPK4 and MPK6. Several stresses, including flg22 treatment, are known to increase MPK11 expression but activation of MPK11 has not been shown. Here, we show that MPK11 activity can indeed be increased through flg22 elicitation. Expression profiling using a small-scale microarray for defense-related genes revealed that cinnamyl alcohol dehyrogenase 5 (CAD5) requires MPK11 for full flg22-induced expression. An mpk11 mutant showed increased flg22-mediated growth inhibition but no altered susceptibility to Pseudomonas syringae, Botrytis cinerea or Alternaria brassicicola.

Role of MPK4 in pathogen-associated molecular pattern-triggered alternative splicing in Arabidopsis

Project description:Alternative splicing (AS) of pre-mRNAs in plants is an important mechanism of gene regulation in environmental stress tolerance but plant signals involved are essentially unknown. Pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) is mediated by mitogen-activated protein kinases and the majority of PTI defense genes are regulated by MPK3, MPK4 and MPK6. These responses have been mainly analyzed at the transcriptional level, however many splicing factors are direct targets of MAPKs. Here, we studied alternative splicing induced by the PAMP flagellin in Arabidopsis.
