Genbank accession number
- Key message
- PSY3 was the only paralog for which transcripts were induced in roots and abiotic stress also affected leaf PSY2 transcript levels; PSY1 mRNA was not elevated in any tissues tested
- We show that both maize and rice possess and express products from duplicate PSY genes, PSY1 (Y1) and PSY2; PSY1 transcript accumulation correlates with carotenoid-containing endosperm
- Connection
- OsPSY~OsPSY3, PSY2, PSY3, a new member of the phytoene synthase gene family conserved in the Poaceae and regulator of abiotic stress-induced root carotenogenesis, PSY3 was the only paralog for which transcripts were induced in roots and abiotic stress also affected leaf PSY2 transcript levels; PSY1 mRNA was not elevated in any tissues tested

- OsPSY~OsPSY3, PSY2, A third phytoene synthase is devoted to abiotic stress-induced abscisic acid formation in rice and defines functional diversification of phytoene synthase genes, The regulatory differences are mirrored by cis-acting elements in the corresponding promoter regions, with light-responsive elements for OsPSY1 and OsPSY2 and an ABA-response element as well as a coupling element for OsPSY3
- OsPSY~OsPSY3, PSY2, A third phytoene synthase is devoted to abiotic stress-induced abscisic acid formation in rice and defines functional diversification of phytoene synthase genes, Since the genomic structures of OsPSY2 and OsPSY3 are comparable, we conclude that they originated from the most recent common ancestor, OsPSY1
