Proximity-labeling using engineered biotin ligases TurboID and miniTurbo enables detection of cell-type-specific and low abundance protein complexes and subcellular proteomes in Arabidopsis and other plants.
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.
The maize CLAVATA receptor, FEA2, functions in the perception of two different ligands, and remarkably that signaling from these different inputs is differentiated by the receptor interacting with two different downstream components.
Functional analyses provide evidence for a complex Nod factor signalling where NFRe is necessary for maintaining an optimal symbiotic signalling in the susceptible root zone, and initiation of nodule primordia on the expanding root system.
Step-wise processing of plant peptide hormone precursors by subtilisin-like proteinases in consecutive compartments of the secretory pathway is required for formation and secretion of the bioactive peptides.
