Gene Details:

• MSU gene ID: LOC_Os05g38150
• RAPdb gene ID: Os05g0455500
• Gene Symbol: OsP5CS OsP5CS1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The ZFP179 transgenic rice exhibited significantly increased tolerance to oxidative stress, the reactive oxygen species (ROS)-scavenging ability, and expression levels of a number of stress-related genes, including OsDREB2A, OsP5CS OsProT, and OsLea3 under salt stress.
• In both rice lines, salt-stress induced OsP5CS1 gene expression, suggesting that proline accumulation occurs via OsP5CS1 gene expression during salt stress.
• An increase in the endogenous ABA level was required for the induction of OsP5CS1 gene expression by salt stress.
• Under salt stress, topical ABA application-induced OsP5CS1 gene expression only in the salt-resistant line but up-regulated OsP5CR gene expression in both rice lines, suggesting that the increased proline accumulation and salt resistance induced by topical ABA application may result from the up-regulation of OsP5CR and not, directly at least, from OsP5CS1.
• Exogenous ABA induces salt tolerance in indica rice (Oryza sativa L.): The role of OsP5CS1 and OsP5CR gene expression during salt stress.
• Over-expression of OsCOIN in transgenic rice lines significantly enhanced their tolerance to cold, salt and drought, accompanied by an up-regulation of OsP5CS expression and an increase of cellular proline level.
• Moreover, the levels of expression of OsP5CS mRNA and content of proline under salt stress condition were compared between a salt-tolerant cultivar, Dee-gee-woo-gen (DGWG) and a salt-sensitive breeding line, IR28.
• Northern blot analysis revealed that the gene for P5CS (OsP5CS) was induced by high salt, dehydration, treatment of ABA and cold treatment, while it was not induced by heat treatment.
• A cDNA for delta1-pyrroline-5-carboxylate (P5C) synthetase (cOsP5CS), an enzyme involved in the biosynthesis of proline, was isolated and characterized from a cDNA library prepared from 14-day-old seedlings of Oryza sativa cv.
