A genome-wide view of the gene regulatory network governed by WRKY33 has identified key targets that negatively regulate ABA biosynthesis to provide immunity against infection by a necrotrophic fungus.
A chewing herbivore induced WRKY transcription factor induces jasmonate-dependent defences and supresses gibbererellin-dependent growth, the latter of which renders rice plants more susceptible to secondary infestation by a piercing-sucking herbivore.
Genetic and biochemical analyses demonstrate that cell-surface lectin receptors can potentially function as extracellular NAD+-binding receptors and provide direct evidence for extracellular NAD+ being a bona fide endogenous signaling molecule in plants.
Plants and humans use a shared mechanism, the eukaryotic metabolic sensor TARGET OF RAPAMYCIN protein kinase and its substrate, an RNA-binding protein called LARP1, to coordinate post-transcriptional gene expression.
Allelic MLA immune receptors have an exceptional propensity to directly detect sequence-unrelated pathogen effectors and this feature might have facilitated functional diversification of the receptor in the host population.
Structure/function studies of a plant pathogen effector in complex with a host disease resistance protein domain reveal the molecular basis for recognition and underpin future engineering of immunity in crops.
