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.
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.
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.
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.
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.
Expression of plant immune genes is controlled by the opposing actions of ubiquitin ligases and deubiquitinases that modify the master coactivator NPR1, thereby regulating its intrinsic transcriptional activity.
