A Third Phytoene Synthase Is Devoted to Abiotic Stress-Induced Abscisic Acid Formation in Rice and Defines Functional Diversification of Phytoene Synthase Genes   [PDF]

Plant Physiology, 2008
AbstractWe here report on the characterization of a novel third phytoene synthase gene (PSY) in rice (Oryza sativa), OsPSY3, and on the differences among all three PSY genes with respect to the tissue-specific expression and regulation upon various environmental stimuli.

Transcriptome-sequencing analyses reveal flower color formation in Strelitzia reginae

Biologia Plantarum, 2020
Strelitzia reginae is a popular cut flower that has blue petals and orange sepals. Flower color is an important plant trait; however, little is known about its molecular mechanisms in S. reginae.

Phytoene Synthase Gene ( PSY ) from Sweet Potato ( Ipomoea batatas Lam . ) Enhances Tolerance to Abiotic Stress

Brazilian Archives of Biology and Technology, 2018
Phytoene synthase (PSY) is the rate-limiting enzyme for carotenoid biosynthesis. To date, several studies focused on PSY genes in the context of abiotic stress responses.

Transcript Abundance of Phytoene Synthase 1 and Phytoene Synthase 2 Is Associated with Natural Variation of Storage Root Carotenoid Pigmentation in Carrot [PDF]

Journal of the American Society for Horticultural Science, 2014
Carotenoids are isoprenoid compounds synthesized in plants that serve as photoprotectants essential for photosynthesis and provide plant tissues with red, orange, and yellow pigmentation. These compounds are important in human health, because they serve as both vitamin A precursors as well as having antioxidant properties. Carrot (

In silico identification and analysis of phytoene synthase genes in plants

Genetics and Molecular Research, 2015
In this study, we examined phytoene synthetase (PSY), the first key limiting enzyme in the synthesis of carotenoids and catalyzing the formation of geranylgeranyl pyrophosphate in terpenoid biosynthesis. We used known amino acid sequences of the PSY gene in tomato plants to conduct a genome-wide search and identify putative candidates in 34 sequenced ...

The phytoene synthase gene family in the Grasses [PDF]

Plant Signaling & Behavior, 2009
Carotenoids are a complex class of isoprenoid pigments playing diverse roles in plants and providing nutritional value. Metabolic engineering of the biosynthetic pathway has been of interest to specifically address global vitamin A deficiency by breeding cereal crop staples in the Poaceae (Grass family) for elevated levels of provitamin A carotenoids ...

A carotenoid-deficient mutant in Pantoea sp. YR343, a bacteria isolated from the rhizosphere of Populus deltoides, is defective in root colonization

Frontiers in Microbiology, 2016
The complex interactions between plants and their microbiome can have a profound effect on the health and productivity of the plant host. A better understanding of the microbial mechanisms that promote plant health and stress tolerance will enable ...

Active Transposition of Insertion Sequences in Prokaryotes: Insights from the Response of Deinococcus geothermalis to Oxidative Stress

Antioxidants, 2022
Bacterial genomes contain numerous insertion sequences (ISs) as transposable elements involved in actions such as the sequestration, transmission, mutation and activation of genes that can influence the responsive capacity of the organism to ...
