On the structure and function of the phytoene desaturase CRTI from Pantoea ananatis, a membrane-peripheral and FAD-dependent oxidase/isomerase. [PDF]

PLoS ONE, 2012
CRTI-type phytoene desaturases prevailing in bacteria and fungi can form lycopene directly from phytoene while plants employ two distinct desaturases and two cis-tans isomerases for the same purpose. This property renders CRTI a valuable gene to engineer

Designing gRNAs targeting oil palm phytoene desaturase (EgPDS) gene and construction of vectors for oil palm CRISPR/Cas9 study

, 2022
The CRISPR/Cas9 system is a precise and versatile genetic tool used to induce site-specific manipulation in the targeted gene. This study elaborates on the strategy to select the gRNAs targeting the oil palm phytoene desaturase (EgPDS) gene, which ...

Phytoene and phytofluene overproduction by Dunaliella salina using the mitosis inhibitor chlorpropham [PDF]

, 2020
The halotolerant chlorophyte microalga, Dunaliella salina, is one of the richest sources of carotenoids and will accumulate up to 10% of the dry biomass as β-carotene, depending on the integrated amount of light to which the alga is exposed during a ...

The Carrot Phytoene Synthase 2 (DcPSY2) Promotes Salt Stress Tolerance through a Positive Regulation of Abscisic Acid and Abiotic-Related Genes in Nicotiana tabacum

Plants, 2023
Background: Carotenoids, which are secondary metabolites derived from isoprenoids, play a crucial role in photo-protection and photosynthesis, and act as precursors for abscisic acid, a hormone that plays a significant role in plant abiotic stress ...

Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

Advanced Science, EarlyView.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...
