Cytokinin downregulates Photosystem II photochemistry during prolonged darkness in a phytochrome B‐dependent manner

New Phytologist, Volume 250, Issue 6, Page 3846-3866, June 2026.
Cytokinin–phyB signaling modulates PSII photochemistry during prolonged darkness. Summary Cytokinins (CKs) delay dark‐induced senescence, but how they tune photosynthetic function in darkness remains unclear. We investigated the effects of classical aromatic CK benzylaminopurine and CK‐derived compound 1‐(2‐methoxyethyl)‐3‐(1,2,3‐thiadiazol‐5‐yl)urea ...

Localization of the PE methylation pathway and SR-BI to the canalicular membrane

Journal of Lipid Research, 2003
To better understand the regulation of biliary phospholipid and cholesterol excretion, canalicular membranes were isolated from the livers of C57BL/6J mice and abundant proteins separated by SDS-PAGE and identified by matrix-assisted laser desorption ...

Metabolic Enzyme MeHNL11 Regulates MeCAS1b Transcription for Cyanide Reutilization in Response to Nitrate Deficiency in Cassava

Plant Biotechnology Journal, Volume 24, Issue 6, Page 4121-4135, June 2026.
ABSTRACT Cassava (Manihot esculenta Crantz) exhibits exceptional tolerance to infertile soils and contains abundant cyanogenic glucosides (CGs). Previous research has indicated that CGs can serve as a significant reservoir of organic nitrogen in plants.

MTAP Deletions in Cancer Create Vulnerability to Targeting of the MAT2A/PRMT5/RIOK1 Axis

Cell Reports, 2016
Homozygous deletions of p16/CDKN2A are prevalent in cancer, and these mutations commonly involve co-deletion of adjacent genes, including methylthioadenosine phosphorylase (MTAP).
