چکیده

Plants must adapt to their environment and require mechanisms for sensing their surroundings and responding appropriately. An expanded family of more than 200 leucine-rich repeat (LRR) receptor kinases (LRR-RKs) transduces fluctuating and often contradictory signals from the environment into changes in nuclear gene expression. Two LRR-RKs, BRASSINOSTEROID INSENSITIVE 1 (BRI1), a steroid receptor, and FLAGELLIN SENSITIVE 2 (FLS2), an innate immune receptor that recognizes bacterial flagellin, act cooperatively to partition necessary growth-defense trade-offs. BRI1 and FLS2 share common signaling components and slightly different activation mechanisms. BRI1 and FLS2 are paradigms for understanding the signaling mechanisms of LRR-containing receptors in plants.

Brassinosteroids modulate the efficiency of plant immune responses to microbe-associated molecular patterns.

Metazoans and plants use pattern recognition receptors (PRRs) to sense conserved microbial-associated molecular patterns (MAMPs) in the extracellular environment. In plants, the bacterial MAMPs flagellin and elongation factor Tu (EF-Tu) activate distinct, phylogenetically related cell surface pattern recognition receptors of the leucine-rich repeat receptor kinase (LRR-RK) family called FLS2 an...

A microRNA cascade in plant defense.

MicroRNAs (miRNAs) and other small interfering RNAs (siRNAs) play an important regulatory role in the growth and development of eukaryotes. miRNAs in plants are known to regulate the expressionof a number of key developmental and stress-related genes. New insight into miRNA function was gained recently with the discovery that several miRNA families target genes encoding nucleotide binding site–...

Nuclear Accumulation of the Arabidopsis Immune Receptor RPS4 Is Necessary for Triggering EDS1-Dependent Defense

Recognition of specific pathogen molecules inside the cell by nucleotide-binding domain and leucine-rich repeat (NB-LRR) receptors constitutes an important layer of innate immunity in plants. Receptor activation triggers host cellular reprogramming involving transcriptional potentiation of basal defenses and localized programmed cell death. The sites and modes of action of NB-LRR receptors are,...

Disruption of PAMP-induced MAP kinase cascade by a Pseudomonas syringae effector activates plant immunity mediated by the NB-LRR protein SUMM2.

Pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) serves as a primary plant defense response against microbial pathogens, with MEKK1, MKK1/MKK2, and MPK4 functioning as a MAP kinase cascade downstream of PAMP receptors. Plant Resistance (R) proteins sense specific pathogen effectors to initiate a second defense mechanism, termed effector-triggered immunity (ETI). In a screen...

Brassinosteroids modulate plant immunity at multiple levels.

U pon detection of microbe-associated molecular patterns (MAMPs), plants usually shift cellular activities from normal growth to defense responses called microbeor pathogen-induced immunity (MTI or PTI) (1, 2). Effective regulation of the tradeoffs between growth and immunity according to physiological and pathological conditions is critical for plant fitness in nature. The leucine-rich repeat ...
