Gene Expression and Sequence Analysis of BADH1 Gene in CLSU Aromatic Rice (Oryza sativa L.) Accessions Subjected to Drought and Saline Condition.

The BADH1 was characterized by investigating its association to aroma, drought and salinity stress through sequence and gene expression analysis using the selected aromatic rice accessions from Central Luzon State University, Philippines. Polymorphisms including SNPs, were observed in genomic analysis between the resistant check and the susceptible varieties during saline condition. On the other hand, BADH1 transcript level in tolerant varieties revealed that during salt treatment, the salt tolerant check Pokkali and moderately salt tolerant accession Leyte Special have increased transcript level compared to non-treated saline condition relative to actin. The downstream investigation of the BADH1 using genomic and transcriptomic approach is important information to elucidate the molecular mechanism of fragrance development among aromatic rice in CLSU and its response to abiotic stresses.
