| Title: Identification of QTL and association of a phytoene synthase gene with endosperm colour in durum wheat .
| | Author: Pozniak CJ Knox RE Clarke FR Clarke JM .
| | Journal: Theor . Appl . Genet . Citation: V : 114 ( 3 ) P : 525-37 Year: 2007 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub17131106 Accession (PMID): 17131106 | Matching Sentences:
[ Sen. 4, subscore: 2.00 ]: Sequencing confirmed the presence of four Psy genes in each parent , corresponding to a two member gene family designated as Psy1-1 , Psy1-2 and Psy2-1 and Psy2-2 .
[ Sen. 6, subscore: 2.00 ]: Using Psy1-1 and Psy2-1 allele-specific markers and chromosome mapping , the Psy1 and Psy2 genes were located to the group 7 and 5 chromosomes , respectively .
[ Sen. 8, subscore: 1.00 ]: The Psy1-1 locus co-segregated with the 7B QTL , demonstrating an association of this gene with phenotypic variation for endosperm colour .
[ Sen. 9, subscore: 1.00 ]: This work is the first report of mapping Psy genes and supports the role of Psy1-1 in elevated levels of endosperm colour in durum wheat .

| Title: Gene duplication in the carotenoid biosynthetic pathway preceded evolution of the grasses .
| | Author: Gallagher CE Matthews PD Li F Wurtzel ET .
| | Journal: Plant Physiol .
Citation: V : 135 ( 3 ) P : 1776-83 Year: 2004 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub15247400 Accession (PMID): 15247400 | Matching Sentences:
[ Sen. 6, subscore: 2.00 ]: 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 .
[ Sen. 7, subscore: 1.00 ]: Using a heterologous bacterial system , we demonstrate enzyme function of PSY1 and PSY2 that are largely conserved in sequence except for N and C-terminal domains .

| Title: Nucleotide diversity and molecular evolution of the PSY1 gene in Zea mays compared to some other grass species .
| | Author: Fu Z Yan J Zheng Y Warburton ML Crouch JH Li JS | | Journal: Theor Appl Genet Citation: V : 120 P : 709-20 Year: 2010 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub19885651 Accession (PMID): 19885651 | Matching Sentences:
[ Sen. 1, subscore: 1.00 ]: Phytoene synthase ( PSY ) , which is encoded by the phytoene synthase 1 ( PSY1 ) gene , is the first rate-limiting enzyme in the plant carotenoid biosynthetic pathway .
[ Sen. 2, subscore: 1.00 ]: In order to examine the genetic diversity and evolution pattern of PSY1 within the Andropogoneae , sequences of 76 accessions from 5 species ( maize , teosinte , tripsacum , coix , and sorghum ) of the Andropogoneae were tested , along with 4 accessions of rice ( Oryza sativa L ) included as outliers .
[ Sen. 7, subscore: 1.00 ]: The phylogenetic tree based on full-length sequences of PSY1-like regions supported the monophyletic theory of the Andropogoneae and the closest relationship between Zea and Tripsacum among the Andropogoneae .

| Title: Deciphering the genomic structure , function and evolution of carotenogenesis related phytoene synthases in grasses .

[ Sen. 3, subscore: 1.00 ]: PSY are nuclear enzymes encoded by a small gene family consisting of three paralogous genes ( PSY1-3 ) that have been widely characterized in rice , maize and sorghum .
[ Sen. 4, subscore: 1.00 ]: RESULTS : In wheat , for which yellow pigment content is extremely important for flour colour , only PSY1 has been extensively studied because of its association with QTLs reported for yellow pigment whereas PSY2 has been partially characterized .

| Title: Isolation and functional characterisation of banana phytoene synthase genes as potential cisgenes .

[ Sen. 9, subscore: 1.00 ]: We provide evidence that PSY in banana is encoded by two paralogs ( PSY1 and PSY2 ) , each with a similar gene structure to homologous genes in other monocots .
[ Sen. 11, subscore: 1.00 ]: Functional analysis of PSY1 and PSY2 in rice callus and E coli demonstrates that both genes encode functional enzymes , and that Asupina PSYs have approximately twice the enzymatic activity of the corresponding Cavendish PSYs .
