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.
