Score: 6.00 | Title: Overexpression of Rab16A gene in indica rice variety for generating enhanced salt tolerance .
| Author: Ganguly M Datta K Roychoudhury A Gayen D Sengupta DN Datta SK | Journal: Plant Signal Behav Citation: V : 7 P : Year: 2012 Type: Publisher | Literature: oryza Field: abstract Doc ID: pub22499169 Accession (PMID): 22499169 | Matching Sentences: [ Sen. 4, subscore: 2.00 ]: The Rab16A transcript also increased gradually with seed maturity , with its maximal accumulation at 30 d after pollination ( DAP ) ie , fully matured seeds , explaining the protective role of Rab16A gene during seed maturation . [ Sen. 1, subscore: 1.00 ]: We report here the overexpression of Rab16A full length gene ( promoter + ORF ) , from the salt-tolerant indica rice Pokkali , in the salt-susceptible indica rice variety Khitish , via particle bombardment . [ Sen. 5, subscore: 1.00 ]: Enhanced tolerance to salinity was observed in the plants transformed with Rab16A . [ Sen. 7, subscore: 1.00 ]: All these results indicated that the overproduction of RAB16A protein in the transgenics enable them to display enhanced tolerance to salinity stress with improved physiological traits . [ Sen. 8, subscore: 1.00 ]: Our work demonstrates the profound potential of Group 2 LEA proteins ( to which RAB16A belongs to ) in conferring stress tolerance in crop plants through their genetic manipulation .

Score: 5.00 | Title: Transgenic tobacco plants overexpressing the heterologous lea gene Rab16A from rice during high salt and water deficit display enhanced tolerance to salinity stress .
| Author: RoyChoudhury A Roy C Sengupta DN | Journal: Plant Cell Rep Citation: V : 26 P : 1839-59 Year: 2007 Type: MEDLINE | Literature: oryza Field: abstract Doc ID: pub17554543 Accession (PMID): 17554543 | Matching Sentences: [ Sen. 3, subscore: 2.00 ]: Expression of Rab16A transcript driven by its own promoter ( stress inducible ) in T2 progenies , only when triggered by salinity/ABA/PEG ( Polyethylene glycol ) -mediated dehydration , but not at the constitutive level , led to the stress-induced accumulation of RAB16A protein in the leaves of transgenic plants . [ Sen. 7, subscore: 2.00 ]: These findings establish the potential role of Rab16A gene in conferring salt tolerance without affecting growth and yield , as well as pointing to the fact that the upstream region of Rab16A behaves as an efficient stress-inducible promoter . [ Sen. 1, subscore: 1.00 ]: The full length Rab16A , from the indica rice Pokkali , was introduced into tobacco by Agrobacterium-mediated transformation .

Score: 3.00 | Title: Glucose modulates the abscisic acid-inducible Rab16A gene in cereal embryos .
| Author: Toyofuku K Loreti E Vernieri P Alpi A Perata P Yamaguchi J | Journal: Plant Mol . Biol . Citation: V : 42 ( 3 ) P : 451-60 Year: 2000 Type: ARTICLE | Literature: oryza Field: abstract Doc ID: pub10798615 Accession (PMID): 10798615 | Matching Sentences: [ Sen. 1, subscore: 1.00 ]: Glucose effects on the expression of the abscisic acid-inducible Rab16A gene were examined in rice and barley embryos . [ Sen. 2, subscore: 1.00 ]: Glucose feeding to rice embryos negatively affects the endogenous abscisic acid content and represses the promoter activity of the Rab16A gene . [ Sen. 3, subscore: 1.00 ]: Glucose repression of the Rab16A gene takes place both at a transcriptional and a post-transcriptional level .

Score: 3.00 | Title: Comparative functional analysis of three abiotic stress-inducible promoters in transgenic rice .
| Author: Rai M He C Wu R | Journal: Transgenic Res Citation: V : P : Year: 2009 Type: Publisher | Literature: oryza Field: abstract Doc ID: pub19357984 Accession (PMID): 19357984 | Matching Sentences: [ Sen. 1, subscore: 1.00 ]: To identify minimal effective promoters for driving abiotic stress-inducible transgene expression in rice , we selected promoter elements of three stress-responsive genes , viz . rab16A coding for dehydrin , OsABA2 coding for zeaxanthin epoxidase , and a gene coding for a hypothetical protein ( HP1 ) based on the presence of ABA- , salt and drought-responsive cis-acting elements . [ Sen. 4, subscore: 1.00 ]: The rab16A and HP1 promoters resulted in high levels of constitutive expression . [ Sen. 5, subscore: 1.00 ]: While induction of GUS activity was generally two to threefold for all the treatments in roots for both the promoters , induction in leaves was generally insignificant , the exceptions being rab16A in response to continuous salt stress and HP1 in response to water deficit .

[ Sen. 2, subscore: 1.00 ]: The activity of rab16A promoter was induced by ABA and osmotic stresses in various it issues of vegetative and floral organs . [ Sen. 3, subscore: 1.00 ]: In anthers and embryos , rab16A promoter was active in the absence of ABA .
