Disease relevance of Plant Diseases

• Rhizobium infection and nodulation: a beneficial plant disease [1]?
• The antimicrobial metabolite 2,4-diacetylphloroglucinol (2,4-DAPG) contributes to the capacity of Pseudomonas fluorescens strain CHA0 to control plant diseases caused by soilborne pathogens [2].
• Lysobacter enzymogenes strain C3, a biological control agent for plant diseases, produces multiple extracellular hydrolytic enzymes and displays antimicrobial activity against various fungal and oomycetous species [3].
• Phenazines produced by members of several bacterial genera are biologically active metabolites that function in microbial competitiveness, the suppression of soil-borne plant diseases and virulence in infectious disease [4].
• Zwittermicin A is a novel antibiotic produced by Bacillus cereus UW85, which suppresses certain plant diseases in the laboratory and in the field [5].

High impact information on Plant Diseases

• The extracellular domain contains 25 tandem leucine-rich repeats that resemble repeats found in animal hormone receptors, plant disease resistance genes, and genes involved in unknown signaling pathways controlling plant development [6].
• Nitric oxide functions as a signal in plant disease resistance [7].
• This is the first study that implicates thioredoxin activity in the regulation of plant disease resistance [8].
• A gain-of-function mutation in a plant disease resistance gene leads to constitutive activation of downstream signal transduction pathways in suppressor of npr1-1, constitutive 1 [9].
• SGT1b was identified recently as a factor involved in plant disease resistance signaling, and SGT1 from barley and tobacco extracts was shown to interact with SCF ubiquitin ligases [10].

Chemical compound and disease context of Plant Diseases

• Intraspecific protoplast fusion was used to produce stable prototrophic recombinants of Streptomyces melanosporofaciens EF-76, a biocontrol agent of plant disease producing geldanamycin [11].

Biological context of Plant Diseases

• The L6, N, and RPS2 genes, which control resistance to three widely different pathogen types, are the foundation of a class of plant disease resistance genes that can be referred to as nucleotide binding site/leucine-rich repeat resistance genes [12].
• Taken together, these results suggest that the tobacco myb1 gene encodes a signaling component down-stream of SA that may participate in transcriptional activation of PR genes and plant disease resistance [13].
• A major class of plant disease resistance (R) genes encodes leucine-rich-repeat proteins that possess a nucleotide binding site and amino-terminal similarity to the cytoplasmic domains of the Drosophila Toll and human IL-1 receptors [14].
• Nod2 and its homologue, Nod1, are members of a growing family of cytosolic factors related to the apoptosis regulator Apaf-1 and a class of plant disease resistance proteins [15].
• Salicylic acid (SA) plays a key role in plant disease resistance and hypersensitive cell death but is also implicated in hardening responses to abiotic stressors [16].

Associations of Plant Diseases with chemical compounds

• Involvement of specific calmodulin isoforms in salicylic acid-independent activation of plant disease resistance responses [17].
• The effect of the abiotic stress hormone abscisic acid on plant disease resistance is a neglected field of research [18].
• A plant disease resistance gene, of the kind involved in "gene-for-gene" interactions with pathogens, has been cloned and found to encode a putative serine/threonine kinase [19].
• Various environmental isolates of B. cepacia are, however, capable of degrading environmental pollutants, such as trichloroethylene, 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), etc., and are also highly effective in controlling plant diseases caused by nematodes and fungi [20].
• Vitamin B1 functions as an activator of plant disease resistance [21].

Gene context of Plant Diseases

• Molecular recognition of pathogen attack occurs inside of plant cells in plant disease resistance specified by the Arabidopsis genes RPS2 and RPM1 [22].
• Reduced expression of AKR2 by using the antisense technique results in small necrotic areas in leaves accompanied by higher production of H2O2, similar to the hypersensitive response to pathogen infection in plant disease resistance [23].
• RAR1 and its interacting partner SGT1 play a central role in plant disease resistance triggered by a number of resistance (R) proteins [24].
• Instead, our findings demonstrate that this response is mediated by a cytosolic, plant disease resistance-like protein called CARD4/Nod1 [25].
• Previous work has shown that RPS5 encodes a member of the nucleotide binding site-leucine rich repeat class of plant disease resistance genes [26].
