TL;DR: High molecular weight forms of SBEII demonstrated a higher affinity for in vitro glucan substrates than monomers, providing direct evidence for the existence of protein complexes involved in amylopectin biosynthesis.

TL;DR: The data demonstrate continuous synthesis and degradation of carotenes and Chl a in photosynthesizing leaves and indicate distinct acclimatory responses of their turnover to changing irradiance.

TL;DR: Under low light, leaves invested less in structural components and more in light harvesting, as manifested by low leaf dry mass per area (LMA) and enhanced mass-based accumulation of chlorophyll and carotenoids, especially lutein and neoxanthin.

TL;DR: This work investigates carotenoid and apocarotenoids formation in Arabidopsis in response to enhanced pathway flux upon PSY overexpression and shows that, in chloroplasts, surplus PSY was partially soluble, localized in the stroma and, therefore, inactive, whereas the membrane-bound portion mediated a doubling of phytoene synthesis rates.

TL;DR: Inhibition of carotenoid biosynthesis by NF may initially enhance metabolic flux in the pathway upstream of phytoene, presumably compensating for short supply of β-C.
