Signals originating within plastids modulate organelle differentiation by transcriptionally regulating nuclear-encoded genes. These retrograde signals are also integral regulators of plant development, including leaf morphology. The clb5 mutant displays severe morphology defects due to Apocarotenoid Signal 1 (ACS1) accumulation in the developmentally arrested plastid. Transcriptomic analysis validates that ACS1 deregulates hundreds nuclear genes, suppression most genes encoding plastid...
A level of redundancy and interplay among the transcriptional regulators floral development safeguards a plant's reproductive success ensures crop production. In present study, an additional layer complexity in regulation meristem (FM) identity flower is elucidated linking carotenoid biosynthesis metabolism to determinate flowering. The accumulation subsequent cleavage diverse array ζ-carotenes chloroplast biogenesis 5 (clb5) mutant Arabidopsis results reprogramming meristematic gene...
Abstract Plant carotenoids are precursors to phytohormones and signaling molecules, playing critical roles in plant development, an emerging area of research. This study investigates the function undefined apocarotenoid ACS1 signal modulating particularly its impact on morphologenesis lateral organs apical meristems. By levels under varying light conditions, we demonstrate dynamic role leaf root development. Notably characteristic radial morphology clb5 mutant reverts normal even days...
