Genome Engineering Tools for Functional Genomics and Crop Improvement in Legumes

Deteriorating environmental conditions and ever-increasing population have led to one of the biggest challenges of producing food sufficient to feed the world. New methods/tools are required to generate high-yielding crop plants to meet the food demand of the world population. Legumes are very important food crops especially in the developing countries. Genome-editing methods, like zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced palindromic repeat (CRISPR)/CRISPR-associated 9 (Cas9), can serve as important tools in studying the role of legume genes in controlling various agronomic traits, such as resistance/tolerance to biotic and abiotic stresses, nitrogen fixation, desired oil accumulation in seeds, etc. in legumes. These methods along with bioinformatics tools are being used to generate new genetic variations via deleting/editing endogenous gene sequence(s), which are involved in various cellular and/or metabolic pathways to enhance crop productivity. These methods can also be used to add and/or delete transgenes from the existing transgenic events. Genome engineering technologies have a promising future in legume genome editing owing to their efficacy and versatility.
