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 …

Phytoene synthase (PSY) is the first committed enzyme of the carotenoid biosynthesis
pathway and the most important point of regulation. Carotenoids are precursors of abscisic …

Abscisic acid (ABA) plays a vital role in mediating abiotic stress responses in plants. De
novo ABA biosynthesis involves cleavage of carotenoid precursors by 9-cis …

Abiotic stress stimuli induce the increased synthesis of abscisic acid (ABA), which is
generated through the cleavage of xanthophyll precursors. To cope with the increased …

Abscisic acid (ABA) is an important regulator of plant responses to environmental stresses
and an absolute requirement for stress tolerance. Recently, a third phytoene synthase …

Carotenoids are plastidial isoprenoids required for photoprotection and phytohormone
production in all plants. In tomato (Solanum lycopersicum), carotenoids also provide color to …

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 …

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 …

Carotenoids are plastidial isoprenoids essential for the protection of photosynthetic tissues
against excess light. They also serve as precursors of apocarotenoid hormones such as …

Carotenoids are plastidial isoprenoids required for photosynthesis and production of
hormones such as abscisic acid (ABA) in all plants. In tomato (Solanum lycopersicum) …
