Climate change has posed a challenge for food security all over the world in the form of fluctuating crop yields and novel disease outbreaks in plants. Human society's overdependence on a few food crops does not seem a wise precedence. There are numerous underutilized/orphan/neglected legumes growing in the Indian desert regions that can come to the rescue and act as balanced and sustainable sources of nutrients and health-benefitting nutraceuticals. However, challenges such as low plant yield, unidentified metabolic pathways and off-flavor in the food products derived from them prevent the realization of their full potential. Conventional breeding techniques are too slow to achieve the desired modifications and cater to the sharply rising demand for functional foods. The novel gene editing tools like CRISPR-Cas provide more precise tool to manipulate the target genes with or without introduction of foreign DNA and therefore, have better chances to be accepted by governments and societies. The current article reports some of the relevant 'gene editing' success stories with respect to nutraceutical and flavor profiles in the popular legumes. It highlights gaps and future potential, along with areas requiring caution, in underutilized edible legumes of the Indian (semi) arid regions like Prosopis cineraria, Acacia senegal and Cyamopsis tetragonoloba.
