Journal ArticleDOI
Characterizing the Saltol Quantitative Trait Locus for Salinity Tolerance in Rice
Michael J. Thomson,Marjorie de Ocampo,James Egdane,M. Akhlasur Rahman,M. Akhlasur Rahman,A.G. Sajise,Dante Adorada,Dante Adorada,Ellen Tumimbang-Raiz,Eduardo Blumwald,Zeba I. Seraj,Rakesh Singh,Glenn B. Gregorio,Abdelbagi M. Ismail +13 more
TL;DR: While the Saltol locus presents a complex scenario, it provides an opportunity for marker-assisted backcrossing to improve salt tolerance of popular varieties followed by targeting multiple loci through QTL pyramiding for areas with higher salt stress.
Journal ArticleDOI
Salinity tolerance, Na+ exclusion and allele mining of HKT1;5 in Oryza sativa and O. glaberrima: many sources, many genes, one mechanism?
TL;DR: Significant variation in salinity tolerance exists within both cultivated Oryza species, and this is the first report of significant tolerance in O. sativa and O. glaberrima.
Journal ArticleDOI
Exploring novel genetic sources of salinity tolerance in rice through molecular and physiological characterization
M. Akhlasur Rahman,Michael J. Thomson,M Shah-E-Alam,Marjorie de Ocampo,James Egdane,Abdelbagi M. Ismail +5 more
TL;DR: New salt-tolerant landraces were identified that are genetically and physiologically distinct from known donors and could provide new sources of quantitative trait loci/alleles for salt tolerance for use in molecular breeding.
Journal ArticleDOI
Physiological Responses of Contrasting Rice Genotypes to Salt Stress at Reproductive Stage
Maria Elisa B. Gerona,Maria Elisa B. Gerona,Marjorie P. Deocampo,James Egdane,Abdelbagi M. Ismail,Maribel L. Dionisio-Sese +5 more
TL;DR: Physiological measurements and pollen viability analysis revealed that Sadri (moderately tolerant at the seedling stage) is sensitive to salt stress at the flowering stage, which will be useful in breeding salt tolerant varieties at both seedling and reproductive stages by selecting appropriate genotypes and phenotypes.
