Serine protease inhibitors (serpins) are found in all kingdoms of life and play essential roles multiple physiological processes. Owing to the diversity superfamily, phylogenetic analysis is challenging prokaryotic serpins have been speculated acquired from Metazoa through horizontal gene transfer due their unexpectedly high homology. Here, we leveraged a structural alignment diverse generate comprehensive 6,000-sequence phylogeny that encompasses life. We show addition central "hub" highly...
Chloroplasts act as environmental sensors, enabling rapid plant stress responses through operational retrograde signaling. While these signals operate on minutes-to-hours' time scales, their cumulative impact and function across a plant's lifecycle in field conditions remains unknown. We investigated if signaling's transient changes to gene expression have effects by generating wheat mutants with primed SAL1-PAP pathway responsiveness. After confirming photosynthesis drought resilience under...
Abstract PHYTOENE SYNTHASE (PSY) is a rate-limiting enzyme catalysing the first committed step of carotenoid biosynthesis, and changes in PSY gene expression and/or protein activity alter composition plastid differentiation plants. Four genetic variants (psy-4, psy-90, psy-130, psy-145) were identified using forward genetics approach that rescued leaf virescence phenotypes abnormalities displayed by Arabidopsis CAROTENOID ISOMERASE (CRTISO) mutant ccr2 (carotenoid chloroplast regulation 2)...

ABSTRACT PHYTOENE SYNTHASE (PSY) is a rate-limiting enzyme catalysing the first committed step of carotenoid biosynthesis, and changes in PSY gene expression and/or protein activity alter composition plastid differentiation plants. Here we identified four genetic variants ( psy −4 , −90 −130 −145 ) using forward genetics approach that rescued leaf virescence phenotypes displayed by Arabidopsis CAROTENOID ISOMERASE (CRTISO) mutant ccr2 chloroplast regulation 2 when grown under shorter...
