A genetic screen for increasing metabolic flux in the isoprenoid pathway of Saccharomyces cerevisiae: Isolation of SPT15 mutants using the screen

Metabolic Engineering Communications, 2016
A genetic screen to identify mutants that can increase flux in the isoprenoid pathway of yeast has been lacking. We describe a carotenoid-based visual screen built with the core carotenogenic enzymes from the red yeast Rhodosporidium toruloides.

Unraveling transcriptomics of sorghum grain carotenoids: a step forward for biofortification

BMC Genomics, 2023
Background Sorghum (Sorghum bicolor [L.] Moench) is a promising target for pro-vitamin A biofortification as it is a global staple crop, particularly in regions where vitamin A deficiency is prevalent.

The Intellectual and Technical Property Components of pro-Vitamin A Rice (GoldenRiceTM): A Preliminary Freedom-To-Operate Review [PDF]

, 2000
Rice is a staple food for millions of people, predominantly in Asia, but lacks essential nutritional components such as Vitamin A. This is very important for over 180 million children and women of child bearing age who suffer from Vitamin A deficiency in

Chromosome‐Level Genome Assembly of the Allotetraploid Gynostemma pentaphyllum Provides Novel Insights Into the Biosynthesis of Ginsenoside and Gypenoside LVI

Plant Biotechnology Journal, EarlyView.
ABSTRACT Gynostemma pentaphyllum, a herb used in tea and traditional Chinese medicine, shows geographic variation in its production of valuable dammarane‐type ginsenosides and gypenoside LVI between populations from Suining (SN) and Nanning (NN). To elucidate the mechanisms underlying this differential metabolite accumulation, a chromosome‐level genome

Seed‐specific overexpression of phytoene synthase: increase in carotenoids and other metabolic effects [PDF]

The Plant Journal, 1999
SummaryA bacterial phytoene synthase (crtB) gene was overexpressed in a seed‐specific manner and the protein product targeted to the plastid in Brassica napus (canola). The resultant embryos from these transgenic plants were visibly orange and the mature seed contained up to a 50‐fold increase in carotenoids. The predominant carotenoids accumulating in

Integrated metabolic profiling and transcriptome analysis of pigment accumulation in Lonicera japonica flower petals during colour-transition

BMC Plant Biology, 2021
Background Plants have remarkable diversity in petal colour through the biosynthesis and accumulation of various pigments. To better understand the mechanisms regulating petal pigmentation in Lonicera japonica, we used multiple approaches to investigate ...

Overexpression of beta-carotene hydroxylase enhances stress tolerance in Arabidopsis [PDF]

, 2002
Plant stress caused by extreme environmental conditions is already a principal reason for yield reduction in crops. The threat of global environment change makes it increasingly important to generate crop plants that will withstand such conditions ...

A Natural LTR Retrotransposon Insertion in the Promoter of GhNAC140‐Dt Boosts Cotton Lint Yield

Plant Biotechnology Journal, EarlyView.
ABSTRACT Transposable elements (TEs) are fundamental drivers of crop evolution and domestication. Whereas the underlying mechanisms of TE‐mediated gene activation remain poorly understood. Lint percentage is an important yield component in cotton. Here, we report a retrotransposon insertion in the promoter of GhNAC140‐Dt, a secondary wall NAC encoding ...

The yl Gene of Maize Codes for Phytoene Synthase [PDF]

Genetics, 1996
Abstract The cloned yl locus of maize was sequenced and found to encode phytoene synthase. Different “wild-type” alleles of the locus were found to differ by the insertion of transposable elements in their promoter and polyA addition regions, and by the length of a CCA tandem repeat series, without any obvious effect on function of the ...

Functional Characterization and in Silico Analysis of Phytoene Synthase Family Genes Responsible for Carotenoid Biosynthesis in Watermelon (Citrullus lanatus L.)

Agronomy, 2020
Carotenoids are the main pigments in watermelon (Citrullus lanatus L.) fruit and contribute to its aesthetic and nutritional value. Phytoene synthase (PSY) is reported to be the first rate-limiting enzyme in carotenogenesis and controls the carotenoid ...
