Summary

Sesame, one of the important oilseed crops, is valued for its high quality oil rich in polyunsaturated fatty acids (PUFA) and thus offers excellent health benefits. The oil also has unique antioxidative property that increases its keeping quality by preventing oxidative rancidity. However, the research efforts for developing improved sesame cultivars having tolerance to biotic and abiotic stresses have been rather meager so far. Sesame is largely cultivated in marginal lands by resource-poor farmers and is thereby prone to several abiotic stresses. The crop possesses effective tolerance to drought due to its extensive root system. Preliminary studies have been carried out in sesame regarding salt, drought, and heavy metal stress. Parameters such as root and shoot morphology, cuticle thickness, antioxidative enzymes, malondialdehyde, proline content, and so on have been assessed under stressed and control conditions. Role of stress-associated genes and their products such as lipid transfer proteins, caleosins, steroid dehydrogenase, phytostatins, γ-aminobutyric acid, metallothioneins involved in diverse stresses are under investigation. The presence of phenylpropanoid compounds, namely, lignans, an innate nonenzymatic antioxidant defense mechanism against reactive oxygen species in sesame, is a special area being researched. However, the areas that still remain untouched include waterlogging and chilling stress, both of which are highly detrimental to the crop survival. Inspite of huge repertoire of germplasm collection, limited research efforts on the use of conventional and biotechnological methodologies have resulted in minimal success in developing abiotic stress-tolerant cultivars. The absence of efficient in vitro regeneration protocols further compounds challenges for development of desired novel genotypes. The possible strategies that could be helpful in incorporating abiotic stress tolerance in plants have been discussed here along with the fundamental studies dealing with different stresses and their effects on sesame, followed by information on stress-related genes under focus in sesame.
