Xanthophylls are a class of carotenoids that important micronutrients for humans. They often found esterified with fatty acids in fruits, vegetables, and certain grains, including bread wheat (Triticum aestivum). Esterification promotes the sequestration accumulation carotenoids, thereby enhancing stability, particularly tissues such as harvested grain. Here, we report on plant xanthophyll acyltransferase (XAT) is both necessary sufficient esterification XAT contains canonical...
Peyote (Lophophora williamsii) is an entheogenic and medicinal cactus native to the Chihuahuan desert. The psychoactive hallucinogenic properties of peyote are principally attributed phenethylamine derivative mescaline. Despite isolation mescaline from over 120 years ago, biosynthetic pathway in plant has remained undiscovered. Here, we use a transcriptomics homology-guided gene discovery strategy elucidate near-complete l-tyrosine We identified cytochrome P450 that catalyzes 3-hydroxylation...
Abstract Opium poppy accumulates copious amounts of several benzylisoquinoline alkaloids including morphine, noscapine, and papaverine, in the specialized cytoplasm laticifers, which compose an internal secretory system associated with phloem throughout plant. The contiguous latex includes abundance related proteins belonging to pathogenesis-related (PR)10 family known collectively as major (MLPs) representing at least 35% total cellular protein content. Two MLP/PR10 proteins, thebaine...
SUMMARY: Ninety-three coryneform bacteria were tested with various acids and bases on the basis of these tests, five strains identified as Brevibacterium linens. This identification correlated that made by other methods, thus confirming suggestion Grecz & Dack (1961) B. linens could be certain colour reactions. Further studies indicated reactions are probably associated presence a specific carotenoid-like substance located in bacterial membrane.
PROTON GRADIENT REGULATION 5 (PGR5) is essential for generating proton motive force across thylakoid membranes in C 3 plants and supporting photoprotection under fluctuating light conditions. It proposed that this function achieved by regulating cyclic electron flow around Photosystem I. During the evolutionary transition from to 4 photosynthesis, leaf abundance of PGR5 has increased, coinciding with a rise rate. To investigate contribution we generated model monocot Setaria viridis null...
ABSTRACT Metabolic feedback is proposed to modulate nuclear gene expression and carotenoid biosynthesis in plastids, however few mechanisms have been identified so far plants. Utilising mutants, overexpression lines, chemical inhibitors, we demonstrate that Arabidopsis LYCOPENE EPSILON CYCLASE ( εLCY ) mRNA levels correlate with changes β-carotenoid accumulation. Transgenic seedlings harbouring the 5’ leader sequence fused FIREFLY LUCIFERASE FiLUC showed reporter responsiveness metabolic...
