A nonproteinaceous Fusarium cell wall extract triggers receptor-like protein-dependent immune responses in Arabidopsis and cotton.

Fusarium wilt caused by the ascomycete fungus Fusarium oxysporum is a devastating disease of many economically important crops. The mechanisms underlying plant responses to F. oxysporum infections remain largely unknown.

Mutation in cyp51b and overexpression of cyp51a and cyp51b confer multiple resistant to DMIs fungicide prochloraz in Fusarium fujikuroi.

Background: Fusarium fujikuroi is a plant pathogen that causes rice bakanae disease. Prochloraz is an imidazole-class sterol, 14α-demethylase inhibitor (DMI), which has been in use for several years as a foliar spray to control Fusarium spp. on agriculturally important monocot crops.

Plant Sense: The Rise of Calcium Channels.

Although calcium (Ca) elevation triggered by abiotic and biotic stimuli has long been a documented phenomenon in plants, the mechanism underlying the control of Ca spikes remains elusive. Recent progress, reported by Tian et al., Wang et al.

Alternative Oxidase Is Involved in the Pathogenicity, Development, and Oxygen Stress Response of .

Alternative oxidase (AOX) is a ubiquinol terminal oxidase that is involved in fungal mitochondrial oxidative phosphorylation. In this study, we analyzed the roles of AOX in by generating BcAOX deletion mutants. The mutants exhibited defects in mycelial growth, sporulation, spore germination, and virulence.

The cloak, dagger, and shield: proteases in plant-pathogen interactions.

Plants sense the presence of pathogens or pests through the recognition of evolutionarily conserved microbe- or herbivore-associated molecular patterns or specific pathogen effectors, as well as plant endogenous danger-associated molecular patterns. This sensory capacity is largely mediated through plasma membrane and cytosol-localized receptors which trigger complex downstream immune signaling cascades. As immune signaling outputs are often associated with a high fitness cost, precise regulation of this signaling is critical.

Plant cell surface molecular cypher: Receptor-like proteins and their roles in immunity and development.

Plant receptor-like proteins (RLPs) are a family of transmembrane receptors which are distinguished from receptor-like kinases (RLKs) by their lack of a cytoplasmic kinase domain. RLPs continue to be implicated in a broad range of plant immunological and developmental processes as critical sensors or participants in receptor complexes on the plasma membrane. RLPs often associate with RLKs to activate or attenuate signal perception and relay.

The APEX Approaches: A Unified LRR-RK Network Revealed.

Leucine-rich repeat receptor kinases (LRR-RKs) represent a large and functionally diverse family of transmembrane proteins critical for signal recognition and transduction at the plant cell plasma membrane. Here, we discuss a recent report which used a systems-level approach to validate key paradigms by constructing an LRR-RK interaction network model.
