Abiotic stresses are the main factors that restrict some areas to practice agriculture worldwide. Rice, a staple food for more than half of the world?s population, has limited tolerance to cold stress. In subtropical areas, early planting exposes rice seedlings to cold stress which impairs their development, turning them more vulnerable to other stresses such as herbicide injury. The objective of this study was to evaluate the effect of cold stress combined with bispyribac-sodium application on molecular patterns of rice seedlings. A growth chamber experiment was conducted twice in 2012 at University of Arkansas, Fayetteville, AR, US. The treatments were composed by: factor A - rice cultivars: IRGA 424 (cold tolerant) and EPAGRI 109 (cold susceptible); factor B - bispyribac-sodium application and a untreated check; and factor C - cold for two days before herbicide spray (short term acclimation), cold for two days immediately after spray (non-acclimated plants); cold since emergence (long term acclimation) and a warm check. Quantitative gene expression at 48 hours after herbicide application (HAT) of OsRAN2 and OsFAD8 - cold; OsGSTL2 and CYP72A21 - herbicide related markers were recorded. OsRAN2 and OsGSTL2 showed good response to cold, herbicide and cultivars, characterizing a cross-talk and indicating that these |
