Catalogued from PDF version of thesis. Includes bibliographical references (pages 36-40). The study was conducted on transgenic rice, BR75, a high-yielding but salt-sensitive genotype previously transformed with the Pc_PVA1 gene, at the Plant biotechnology Laboratory of Dhaka University. The aim was to identify presence of the transgene and to assess the response of transgenic seedlings to salt stress. The transgene originated from wild halophytic rice Porteresia coarctata, endemic to coastal Bangladesh and was expected to confer salt tolerance to the transformed sensitive rice, BR75. The wild type or untransformed BR75 and the two transgenic genotypes derived from its transformation, P-46-1 and P-9-4 were used for this experiment. DNA was extracted from the wild type and T1 generation of the transgenic plants. PCR analysis followed by gel electrophoresis was performed with the isolated DNA. Then the performance of transgenic BR75 T2 population in saline condition was investigated. Seedling screening was done following the standard evaluation system (IRRI), and the chlorophyll content of the seedlings were also measured. The results of the validation study were found to be positive, that is to confirm their tolerance status as opposed to the wild type. The two transgenic varieties in this study performed much better than the wild type BR75 in saline condition because these had higher survival rate and chlorophyll content. The present study was conducted with a small subset of the T2 population. In future, more tests like the leaf disk senescence assay, determination of Na:K ratio under saline stress, mRNA analysis needs to be done for a more detailed evaluation. Finally, the transgenic plants should be trialed in the natural saline environment using standard Biosafety Protocols. Eera Ashrafy Anonna B.
