| Title: Expression of delta1-pyrroline-5-carboxylate synthetase gene during drought in rice ( Oryza sativa L ) .
| | Author: Choudhary NL Sairam RK Tyagi A | | Journal: Indian J Biochem . Biophys . Citation: V : 42 ( 6 ) P : 366-70 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub16955737 Accession (PMID): 16955737 | Matching Sentences:
[ Sen. 1, subscore: 2.00 ]: The 45-days-old seedlings of drought resistant ( N-22 , CR143-2-2 ) and susceptible rice ( Oryza sativa L ) genotypes ( Panidhan , Pusa-169 ) were subjected to osmotic stress in PEG-6000 solution of -10 and -16 bar and the relative water content ( RWC ) , proline content , and pyrroline-5-carboxylate synthetase ( P5CS ) activity and its P5CS expression were studied .
[ Sen. 5, subscore: 2.00 ]: The EcoRI , BamHI and XbaI restricted DNA of N-22 and Panidhan genotypes were hybridized with Arabidopsis P5CS sequence and a single band ( approx 2 . 4 kb ) was observed , however , P5CS expression was more in N-22 as compared to Panidhan .
[ Sen. 3, subscore: 1.00 ]: Proline content and P5CS activity increased both in susceptible and tolerant genotypes ; the increase was higher in tolerant genotypes .
[ Sen. 4, subscore: 1.00 ]: Higher proline levels in tolerant genotypes were due to increased P5CS activity .

| Title: Biosynthetic Mechanism of 2-Acetyl-1-pyrroline and Its Relationship with Delta ( 1 ) -Pyrroline-5-carboxylic Acid and Methylglyoxal in Aromatic Rice ( Oryza sativa L ) Callus .
| | Author: Huang TC Teng CS Chang JL Chuang HS Ho CT Wu ML | | Journal: J Agric Food Chem Citation: V : P : Type: Publisher | | Literature: oryza Field: abstract Doc ID: pub18680302 Accession (PMID): 18680302 | Matching Sentences:
[ Sen. 5, subscore: 2.00 ]: The expression levels of P5CS1 and P5CS2 genes were found to be significantly higher in aromatic rice than nonaromatic rice .
[ Sen. 4, subscore: 1.00 ]: Specific enzyme activities of Delta ( 1 ) -pyrroline-5-carboxylic acid-synthetic enzyme including Delta ( 1 ) -pyrolline-5-carboxylic acid synthetase ( P5CS ) and ornithine aminotransferase ( OAT ) increased significantly in aromatic rice varieties .
[ Sen. 7, subscore: 1.00 ]: Upregulation of P5CS in aromatic rice Tainung 72 may contribute to the increase of Delta ( 1 ) -pyrroline-5-carboxylic acid level and thus leads to the accumulation of an extra amount of 2-acetyl-1-pyrroline .

| Title: Characterization of the gene for delta1-pyrroline-5-carboxylate synthetase and correlation between the expression of the gene and salt tolerance in Oryza sativa L | | Author: Igarashi Y Yoshiba Y Sanada Y Yamaguchi-Shinozaki K Wada K Shinozaki K | | Journal: Plant Mol . Biol . Citation: V : 33 ( 5 ) P : 857-65 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub9106509 Accession (PMID): 9106509 | Matching Sentences:
[ Sen. 3, subscore: 2.00 ]: The deduced amino acid sequence of the P5CS protein ( OsP5CS ) from O sativa exhibited 74 . 2% and 75 . 5% homology to that of the P5CS from Arabidopsis thaliana and Vigna aconitifolia , respectively .
[ Sen. 4, subscore: 1.00 ]: 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 .
[ Sen. 7, subscore: 1.00 ]: It was observed that the expression of the P5CS gene and the accumulation of proline in DGWG steadily increased , whereas those in IR28 increased slightly .

| Title: Exogenous proline and trehalose promote recovery of rice seedlings from salt-stress and differentially modulate antioxidant enzymes and expression of related genes .
| | Author: Nounjan N Nghia PT Theerakulpisut P | | Journal: J Plant Physiol Citation: V : 169 P : 596-604 Type: In-Process | | Literature: oryza Field: abstract Doc ID: pub22317787 Accession (PMID): 22317787 | Matching Sentences:
[ Sen. 5, subscore: 1.00 ]: Salt stress ( S , NaCl ) resulted in growth reduction , increase in the Na ( + ) /K ( + ) ratio , increase in Pro level and up-regulation of Pro synthesis genes ( pyrroline-5-carboxylatesynthetase , P5CS ; pyrroline-5-carboxylate reductase , P5CR ) as well as accumulation of hydrogen peroxide ( H ( 2 ) O ( 2 ) ) , increased activity of antioxidative enzymes ( superoxide dismutase , SOD ; peroxidase , POX ; ascorbate peroxidase , APX ; catalase , CAT ) and transcript up-regulation of genes encoding antioxidant enzymes ( Cu/ZnSOD , MnSOD , CytAPX , CatC ) .
[ Sen. 6, subscore: 1.00 ]: Under salt stress , exogenous Pro ( PS ; Pro+NaCl ) reduced the Na ( + ) /K ( + ) ratio , further increased endogenous Pro and transcript levels of P5CS and P5CR , but decreased the activity of the four antioxidant enzymes .
[ Sen. 9, subscore: 1.00 ]: Transcription of P5CS and P5CR was upregulated , the activities of SOD and POX decreased , the activity of APX increased and the transcription of all antioxidant enzyme genes upregulated .
