Crosstalk between abiotic and biotic stress responses: a current view from the points of convergence in the stress signaling networks.
TLDR
Emerging evidence suggests that hormone signaling pathways regulated by abscisic acid, salicylic acid, jasmonic acid and ethylene, as well as ROS signaling pathways, play key roles in the crosstalk between biotic and abiotic stress signaling. Expand
RRS1 and RPS4 provide a dual Resistance-gene system against fungal and bacterial pathogens.
TLDR
This work used map-based cloning and natural variation analysis of 19 Arabidopsis ecotypes to identify a dominant resistance locus against C. higginsianum and found that both RRS1 and RPS4 are required for resistance to R. solanacearum and Pst-avrRps4. Expand
Novel Plant Immune-Priming Compounds Identified via High-Throughput Chemical Screening Target Salicylic Acid Glucosyltransferases in Arabidopsis[W][OA]
TLDR
The results demonstrate that manipulation of the active free SA pool via SA-inactivating enzymes can be a useful strategy for fortifying plant disease resistance and may identify useful crop protectants. Expand
A single amino acid insertion in the WRKY domain of the Arabidopsis TIR-NBS-LRR-WRKY-type disease resistance protein SLH1 (sensitive to low humidity 1) causes activation of defense responses and
TLDR
The data suggest that SLH1 disease resistance signaling may be negatively regulated by its WRKY domain in the R protein and that the constitutive defense activation conferred by the slh1 mutation is inhibited by conditions of high humidity. Expand
Loss of NECROTIC SPOTTED LESIONS 1 associates with cell death and defense responses in Arabidopsis thaliana
TLDR
RNA gel blot analysis revealed that genes associated with disease resistance activation are upregulated in the nsl1 mutants and these plants contain elevated levels of salicylic acid (SA). Expand
ALBINO AND PALE GREEN 10 encodes BBMII isomerase involved in histidine biosynthesis in Arabidopsis thaliana.
TLDR
The histidine limitation induced by apg10 mutation causes dynamic changes of the free amino acid profile, suggesting the existence of a cross-pathway regulatory mechanism of amino acid biosynthesis in plants. Expand
Zepp, a LINE‐like retrotransposon accumulated in the Chlorella telomeric region
TLDR
Detailed sequence analysis of the Chlorella subtelomeric region revealed a novel mechanism of Zepp transposition; successive insertions of each Zepp element into another Zepp as a target, leaving a tandem array of their 3′‐regions with poly(A) tracts facing toward the centromere. Expand
A resource of 5,814 dissociation transposon-tagged and sequence-indexed lines of Arabidopsis transposed from start loci on chromosome 5.
TLDR
The generation of an additional collection of Dissociation (Ds) transposon-tagged, sequence-indexed lines of Arabidopsis thaliana is reported, which totals 17,668 lines and will contribute to progress in functional genomics of plants. Expand
A chemical biology approach reveals an opposite action between thermospermine and auxin in xylem development in Arabidopsis thaliana.
TLDR
The results suggest that the auxin signaling that promotes xylem differentiation is normally limited by SAC51-mediated thermos permine signaling but can be continually stimulated by exogenous auxin analogs in the absence of thermospermine. Expand
Sulfonamides identified as plant immune-priming compounds in high-throughput chemical screening increase disease resistance in Arabidopsis thaliana
TLDR
S sulfonamides potentiate Arabidopsis disease resistance by their novel chemical properties, and are suggested to act as salicylic acid analogs. Expand
