DOI: 10.1021/acs.jproteome.7b00809

Abstract: The membrane protease LonB is an essential protein in the archaeon Haloferax volcanii and globally impacts its physiology. However, natural substrates of the archaeal Lon protease have not been identified. The whole proteome turnover was… read more here.

DOI: 10.1093/plphys/kiaf365

Abstract: Carotenoids serve critical biological functions through their essential contributions to organismal survival and health. As a widely consumed fruit species, peach (Prunus persica) provides humans with valuable carotenoid sources, and these compounds also substantially enhance… read more here.

DOI: 10.1590/1678-4324-2018160558

Abstract: 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. In this study, two phytoene synthase encoding genes, IbPSY1 and… read more here.

DOI: 10.3389/fpls.2018.00255

Abstract: Strigolactones (SLs) are apocarotenoid phytohormones synthesized from carotenoid precursors. They are produced most abundantly in roots for exudation into the rhizosphere to cope with mineral nutrient starvation through support of root symbionts. Abscisic acid (ABA)… read more here.

recommendations! Published in 2022 at "Frontiers in Plant Science"

DOI: 10.3389/fpls.2022.884720

Abstract: Phytoene synthase (PSY) catalyzes the first committed step in the carotenoid biosynthesis pathway and is a major rate-limiting enzyme of carotenogenesis. PSY is highly regulated by various regulators and factors to modulate carotenoid biosynthesis in… read more here.

DOI: 10.3390/plants12101925

Abstract: 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… read more here.
