Phytoene Desaturase: Genes, Enzymes and Phylogenetic Aspects
Journal of Plant Physiology, 1994Summary Recent work on phytoene desaturases and also on ζ-carotene desaturase is presented and discussed. This involves functional complementation of phytoene desaturation by heterologous expression of different genes coding for this enzyme originating from Rhodobacter capsulatus, Erwinia uredovora, and Synechococcus and the enzymatic ...

Phytoene synthase (PSY) and phytoene desaturase (PDS), which catalyze the first and second steps of the carotenoid biosynthetic pathway, respectively, are key enzymes for the accumulation of carotenoids in many plants. We isolated 2 partial cDNAs encoding PSY (AsPSY-1 and AsPSY-2) and a partial cDNA encoding PDS (AsPDS) from Allium sativum. They shared

Phytoene synthase (PSY) and phytoene desaturase (PDS), which catalyze the first and second steps of the carotenoid biosynthetic pathway, respectively, are key enzymes for the accumulation of carotenoids in many plants. We isolated 2 partial cDNAs encoding PSY (AsPSY-1 and AsPSY-2) and a partial cDNA encoding PDS (AsPDS) from Allium sativum. They shared

Pest Management Science, 2014
AbstractTwo major classes of herbicides include inhibitors of protoporphyrinogen oxidase (PPO) and phytoene desaturase (PDS). Plants can evolve resistance to PPO and PDS inhibitors via several mechanisms that include physical changes, resulting in reduced uptake, physiological changes, resulting in compartmentalization or altered translocation, and ...

Carotenoid diversity: a modular role for the phytoene desaturase step
Trends in Plant Science, 1998Abstract Carotenoids play a crucial role in light harvesting and are essential photoprotective agents in photosynthesis. It has also been suggested that their ability to scavenge harmful radicals may offer protection against cancer and heart disease.

Protein Expression and Purification, 1997
Conditions were developed for heterologous expression in Escherichia coli of the membrane-bound cyanobacterial/plant-type phytoene desaturase (PDS) from Synechococcus in an active form. Decrease of growth temperature for the transformant to 28 degrees C resulted in an increase of proteins in a supernatant fraction obtained after pressure disruption (20

The first carotenoid biosynthetic gene from the basidiomycetous yeast Xanthophyllomyces dendrorhous was isolated by heterologous complementation in Escherichia coli. The isolated gene, denominated as crtI, was found to encode for phytoene desaturase. The coding region is interrupted by 11 introns.

Discovery of Novel Pyridazine Herbicides Targeting Phytoene Desaturase with Scaffold Hopping
Journal of Agricultural and Food ChemistryPhytoene desaturase (PDS) is a critical functional enzyme in blocking ζ-carotene biosynthesis and is one of the bleaching herbicide targets. At present, norflurazon (NRF) is the only commercial pyridazine herbicide targeting PDS. Therefore, developing new and diverse pyridazine herbicides targeting PDS is urgently required. In this study, diflufenican (

[Cloning and functional characterization of phytoene desaturase in Andrographis paniculata].
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2016A full-length cDNA of phytoene desaturase (PDS) gene from Andrographis paniculata was obtained through RACE-PCR. The cDNA sequence consists of 2 224 bp with an intact ORF of 1 752 bp (GeneBank: KP982892), encoding a ploypeptide of 584 amino acids. Homology analysis showed that the deduced protein has extensive sequence similarities to PDS from other ...

An efficient CRISPR/Cas9-mediated editing of phytoene desaturase in hexaploid sweetpotato
Plant ScienceCRISPR/Cas9-mediated gene editing has emerged as a pivotal tool for functional genomics and crop improvement. For the first time, we applied CRISPR/Cas9-mediated editing to the IbPDS gene in the purple-fleshed cultivar 'XZS-8', achieving mutation efficiencies up to 98.18 %.
