Isolation and functional characterisation of banana phytoene synthase genes as potential cisgenes

Regulation of Banana Phytoene Synthase (MaPSY) Expression, Characterization and Their Modulation under Various Abiotic Stress Conditions

Phytoene synthase (PSY) is a key regulatory enzyme of carotenoid biosynthesis pathway in plants. The present study examines the role of PSY in carotenogenesis and stress management in banana. Germplasm screening of 10 Indian cultivars showed that Nendran (3011.94 μg/100 g dry weight) and Rasthali (105.35 μg/100 g dry weight) contained the highest and lowest amounts of β-carotene, respectively i...

A third phytoene synthase is devoted to abiotic stress-induced abscisic acid formation in rice and defines functional diversification of phytoene synthase genes.

We 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. The two already known PSYs are under phytochrome control and involved in carotenoid biosynthesis in photosynthetically active tissues...

Genetic analysis of polyketide synthase and peptide synthase genes of ‎cyanobacteria as a mining tool for new pharmaceutical compounds

Cyanobacteria are considered a promising source for new ‎pharmaceutical lead compounds and a large number of chemically diverse and ‎bioactive metabolites have been obtained from cyanobacteria. Despite of ‎several worldwide studies on prevalence of NRPSs and PKSs among the ‎cyanobacteria, none of them included Iranian cyanobacteria of Kermanshah ‎province. Therefore, the aim of this study was t...

Cloning and phylogenetic analysis of phytoene synthase 1 (Psy1) genes in common wheat and related species.

Cloning and phylogenetic analysis of Psy1 genes in common wheat and its relatives would help to understand the genetic diversity and evolution of Psy1 gene in common wheat and its related species. In the present study, common wheat (AABBDD) and eight relative species, including T. urartu (A(u)A(u)), T. boeoticum (A(m)A(m)), T. monococcum (A(m)A(m)), Ae. speltoides (SS), Ae. tauschii (DD), T. di...
