The RNA Export Factor ALY1 Enables Genome-Wide RNA-Directed DNA MethylationThe mRNA export protein ALY1 enables genome-wide RNA-directed DNA methylation, transposon repression, and transgene silencing.
The Protease WSS1A, the Endonuclease MUS81, and the Phosphodiesterase TDP1 Are Involved in Independent Pathways of DNA-protein Crosslink Repair in PlantsThe pathways of DNA-protein crosslink repair in plants are characterized by the protease WSS1A, the DNA endonuclease MUS81, and tyrosyl-DNA phosphodiesterase 1.
Plant U-Box40 Mediates Degradation of the Brassinosteroid-Responsive Transcription Factor BZR1 in Arabidopsis RootsBrassinosteroid signaling tightly controls the degradation of the transcription factor BRASSINAZOLE RESISTANT1 specifically in roots.
RUBY, a Putative Galactose Oxidase, Influences Pectin Properties and Promotes Cell-To-Cell Adhesion in the Seed Coat Epidermis of ArabidopsisA putative galactose oxidase, RUBY, promotes cell-to-cell adhesion between seed coat epidermal cells and modifies galactosylated RG-I pectin in the seed coat mucilage of Arabidopsis.
ETR1/RDO3 Regulates Seed Dormancy by Relieving the Inhibitory Effect of the ERF12-TPL Complex on DELAY OF GERMINATION1 ExpressionA module regulating seed dormancy is uncovered linking the ethylene and DELAY OF GERMINATION1 pathways, shedding light on the role of ethylene in controlling seed dormancy and pre-harvest sprouting.
PRX9 and PRX40 Are Extensin Peroxidases Essential for Maintaining Tapetum and Microspore Cell Wall Integrity during Arabidopsis Anther DevelopmentPRX9 and PRX40 are essential class III peroxidases that act redundantly to cross-link extensins in tapetal cell walls, which prevents tapetum swelling and enables pollen development.
ARC3 Activation by PARC6 Promotes FtsZ-Ring Remodeling at the Chloroplast Division SiteRecruitment of the chloroplast Min-system protein ARC3 to the organelle division site by PARC6 enables ARC3 to interact with and facilitate remodeling of the FtsZ ring during chloroplast division.
Channelrhodopsin-1 Phosphorylation Changes with Phototactic Behavior and Responds to Physiological Stimuli in ChlamydomonasRapid changes in the phosphorylation status of the light receptor ChR1 help the motile green alga Chlamydomonas reinhardtii adapt its phototactic sensitivity to varying environmental conditions.
The Cytochrome b6f Complex Is Not Involved in Cyanobacterial State TransitionsCyanobacterial state transitions, which balance photosystem activities during photosynthesis, depend on the plastoquinone pool redox state but not on cytochrome b6f or phosphorylation reactions.
