Summary

The changing environments pose serious challenges to global agriculture and place unprecedented pressures on the sustainability of agriculture production. Climatic changes have been influencing the severity of environmental stress imposed on vegetable crops. Vegetable production is threatened by various abiotic stresses such as increased soil salinity, drought, temperature fluctuations, and so on. Success in breeding for varieties better adapted to abiotic stresses depends upon the concerted efforts by various research domains including plant and cell physiology, molecular biology, genetics, and breeding. The use of modern molecular biology tools for elucidating the control mechanisms of abiotic stress tolerance and for engineering stress-tolerant crops is based on the expression of specific stress-related genes. In this chapter, we have reviewed the studies reported on various factors responsible for abiotic stress in plants especially in vegetables with reference to chili pepper and onion. Physiological and molecular changes at genetic level during the stress response of plants are discussed briefly. This chapter emphasizes on the recent efforts to improve abiotic stress tolerance in crop plants by employing some of the stress-related genes and transcription factors in chili pepper and onion plants. The conventional breeding methods can be complemented by an array of biotechnological tools to augment vegetable production by saving time and resources. Molecular and genomics analyses have facilitated gene discovery and enabled genetic engineering using several functional or regulatory genes to activate specific or broad pathways related to abiotic stress tolerance in plants. There is a clear and urgent need to introduce stress tolerance genes into crop plants, in addition to establishing gene stacking or gene pyramiding.
