WRKY70 modulates the selection of signaling pathways in plant defense.
Cross-talk between signal transduction pathways is a central feature of the tightly regulated plant defense signaling network. The potential synergism or antagonism between defense pathways is determined by recognition of the type of pathogen or pathogen-derived elicitor. Our studies have identified WRKY70 as a node of convergence for integrating salicylic acid (SA)- and jasmonic acid (JA)-medi...
متن کاملBIK1 function in plant growth and defense signaling.
Plant pathogens can be categorized based on their feeding habits, specifically whether they are biotrophic and feed off of living host tissues, or if they are necrotrophic and feed off of dead and decaying tissues. Not surprisingly, when attacked by pathogens with different feeding habits, plants employ different but overlapping defense strategies to limit pathogen growth and disease developmen...
متن کاملNitric oxide and salicylic acid signaling in plant defense.
Salicylic acid (SA) plays a critical signaling role in the activation of plant defense responses after pathogen attack. We have identified several potential components of the SA signaling pathway, including (i) the H(2)O(2)-scavenging enzymes catalase and ascorbate peroxidase, (ii) a high affinity SA-binding protein (SABP2), (iii) a SA-inducible protein kinase (SIPK), (iv) NPR1, an ankyrin repe...
متن کاملEndosomal trafficking and signaling in plant defense responses.
Plant defense responses are initiated by ligand-receptor recognition. The receptor may contain a motif for endocytosis and endocytosis is important for defense signaling in some cases. Recently, endosomal trafficking during defense has begun to be elucidated. In some cases, defense receptors are internalized into early endosomes, recycled back to the plasma membrane (PM) on recycling endosomes,...
متن کاملRevealing the Elusive Plant Epitranscriptome
RNA is decorated by various chemical modifications that affect the stability and localization of this fragilemolecule. These diverse, highly conserved, covalent modifications also help RNA perform its crucial roles in the cell. Over 100 RNAmodifications have been identified, primarily in noncoding RNAs (e.g., tRNA and rRNA). Less is known about the chemical modification of mRNA, although there ...
