A Key ABA Catabolic Gene, OsABA8ox3, Is Involved in Drought Stress Resistance in Rice
Expressions of ABA biosynthesis genes and catabolism genes are generally co-regulated in plant development and responses to environmental stress. Up-regulation of OsNCED3 gene, a key gene in ABA biosynthesis, has been suggested as a way to enhance plant drought resistance but little is known for the role of ABA catabolic genes during drought stress. In this study, we found that OsABA8ox3 was th...
متن کاملSustained low abscisic acid levels increase seedling vigor under cold stress in rice (Oryza sativa L.)
Stress-induced abscisic acid (ABA) is mainly catabolized by ABA 8'-hydroxylase (ABA8ox), which also strictly regulates endogenous ABA levels. Although three members of the ABA8ox gene family are conserved in rice, it is not clear which stressors induce expression of these genes. Here, we found that OsABA8ox1 was induced by cold stress within 24 h and that OsABA8ox2 and OsABA8ox3 were not. In co...
متن کاملKey Genes Involved in Wheat Response to Salinity Stress and Mapping their Gene Network
Extended Abstract Introduction and Objective: Considering the importance of salinity in wheat and the multigene nature of this trait, the present study was conducted to investigate the expression of key genes involved in the response of wheat to this stress and to create their network. Material and Methods: In this study, the expression of key genes (HKT, DREB, bZIP, NAC, and WARKY) involved...
متن کاملRice OsGL1-6 Is Involved in Leaf Cuticular Wax Accumulation and Drought Resistance
Cuticular wax is a class of organic compounds that comprises the outermost layer of plant surfaces. Plant cuticular wax, the last barrier of self-defense, plays an important role in plant growth and development. The OsGL1-6 gene, a member of the fatty aldehyde decarbonylase gene family, is highly homologous to Arabidopsis CER1, which is involved in cuticular wax biosynthesis. However, whether O...
متن کاملABA-induced Polypeptide Accumulation in Drought Tolerant Rice
It has been estimated that the growing of rice occupies one-third of the world’s total cultivatable land area devoted to cereal crops. As a food stable supply, rice is considered to be the single most important food crop for more than one-half of the world’s population, most of who live in developing countries. The importance of rice can be appreciated when one considers that this cereal crop a...
