“…The roles of these elicitors have almost a similar promotive effect when alpha-amylase activity was recorded. In quiescence strategy of plants, particularly, the rice varieties having SUB1 allele are characterized to induce ethylene for downregulation of few genes, α-amylase being the predominant of those (22). Undoubtedly, less exhaustion of carbohydrates through solubilization for respiratory flask is the prime determinant for quiescence strategy.…”

Abstract:In the present study, the sensitivity of two chemical elicitors: polyamine (PA) and salicylic (SA) acid were exercised for submergence sensitivity in Swarna Sub1A rice variety. Under 5 days of submergence, the antioxidation responses were more distinguished in plants against control. Along with the anti-oxidation modules, significant changes in biomolecule loss were registered through lipid and protein oxidation by 1.91 and 1.46 -fold respectively. PA and SA treated plants were the reliever to recover the membrane potential. Total carbohydrate and reducing sugars were varied under submergence by down regulation of 36.66 and 44.44% as compared to control. This was also supported by regulation of α-amylase activity under submergence that also recovered significantly with PA and SA treatments against submergence. In association with carbohydrate metabolism, Under submergence Swarna Sub1A recorded to be prone with oxidative stress through O 2. -(1.55 fold) and peroxide (1.70-fold) over-accumulation but recovered as PA and SA applied. In both cases, sustenance of non-enzymatic anti-oxidant like total carotenoid and lycopene content were also contributory through down-regulation. The enzymatic anti-oxidation paths like SOD, GPX, CAT and GR were regulated by 11.11, 19.54, 13.65, 10.03% declined respectively and thoroughly discussed with reference to PA and SA interactions.

“…Researchers are attempting to improve photosynthesis in C 3 plants with the aim of boosting yield by achieving overexpression of C 4 -cycle enzymes [89]- [91] but much work remains to accomplish this goal. In a recent review [92], the potential of transgenic approach in improving rice production has been shown by identifying a range of traits that can be addressed to develop transgenic for commercial adoption and cultivation. Response of a plant to environmental stress can range from altered gene expression and cellular metabolism to changes in crop yields [93].…”

Ability to modify plants at the genomic level by advanced molecular technology has enhanced the scope of improvements in plant traits attempted earlier through conventional breeding methods. Techniques such as genetic transformation have opened new vistas whereby functional genes, not commonly present in a particular species can be added from other species. The traits incorporated into the genetically engineered plants in the beginning were confined to those governed by dominant genes, e.g. insecticide resistance and herbicide tolerance but advancements with time now also permit the transfer of complexly inherited traits such as drought and cold tolerance. Transgenic technology is also useful in understanding gene expression and metabolic pathways which can then be used to harness the full genomic potential of the plant. This review presents a narrative on development of transgenics and their use for the improvement of field, industrial and pharmaceuticals crops. In addition, discussions are made on current status on genetically modified crops, hurdles to genetic engineering, overcoming strategies and future scope.

Morphological analysis revealed differences between the three transgenic BrTSR53-OX rice and the wild-type rice. The germination rates of the three transgenic BrTSR53-OX lines of rice were significantly higher than that of the wild type rice, indicating that they were more tolerant to 200 mM NaCl than the wild type rice. In addition, the three transgenic BrTSR53-OX rice lines had significantly longer length of root and shoot compared to the wild type rice. These results suggest that the BrTSR53 gene played an important role in the tolerance of rice to salt stress. Therefore, it might be a potential target for the purpose of improving salt tolerance of rice and other crops.
