The bacterial quorum sensing signal DSF hijacks Arabidopsis thaliana sterol biosynthesis to suppress plant innate immunityThis study highlights that DSF, the quorum sensing signal produced by bacterial phytopathogens, is able to directly modulate plant plasma membrane dynamics by interfering with host lipid profile and thereby, suppress plant immunity responses.
CYP20-3 deglutathionylates 2-CysPRX A and suppresses peroxide detoxification during heat stressPosttranslational modification by a reduced glutathione determines distinctive quaternary structures and functions between two 2-cysteine peroxiredoxin A and B in the chloroplasts.
Genetic and molecular characterization of multicomponent resistance of Pseudomonas against allicinA pseudomonad isolated from garlic has multiple copies of genes on three genomic islands that confer resistance to allicin, a secondary plant product and defense substance that causes disulfide stress.
Metabolome-based prediction of yield heterosis contributes to the breeding of elite riceMetabolite profiles obtained from parental seedlings can predict yield heterosis of rice hybrids with correctly dissected population structure across different growth conditions.
Unfolded protein-independent IRE1 activation contributes to multifaceted developmental processes in ArabidopsisThe Arabidopsis unfolded protein response transducer IRE1 contributes to male gametophyte development using an alternative activation mechanism bypassing the unfolded protein-sensing domain.
Molecular characterization of Chlamydomonas reinhardtii telomeres and telomerase mutantsThis study characterizes the sequence, end structure, and length distribution of Chlamydomonas reinhardtii telomeres and shows that telomerase mutants are defective in telomere maintenance.
The m6A pathway protects the transcriptome integrity by restricting RNA chimera formation in plantsThis study reveals that an m6A-assisted polyadenylation pathway comprising conserved m6A writer proteins and a plant-specific m6A reader contributes to transcriptome integrity in Arabidopsis thaliana by restricting RNA chimera formation at rearranged loci.
Molecular characterization of CHAD domains as inorganic polyphosphate-binding modulesA domain of unknown function termed CHAD, present in all kingdoms of life, is characterized as a specific inorganic polyphosphate-binding domain.
A role for MED14 and UVH6 in heterochromatin transcription upon destabilization of silencingThe TFIIH component UVH6 and the mediator subunit MED14 are differentially required for the release of heterochromatin silencing, and MED14 regulates non-CG DNA methylation in Arabidopsis.
The Arabidopsis homolog of human G3BP1 is a key regulator of stomatal and apoplastic immunityArabidopsis homolog of human G3BP1 negatively regulates plant immunity and defense responses. Atg3bp1 mutant lines show constitutive stomata closure, expression of a number of key defense marker genes, and accumulate salicylic acid.
