Description Accepted date: 12 September 2020
Crop improvement relies on modulating the genes and genomic regions underlying key traits, either directly or indirectly. Direct approaches include overexpression, RNA interference, genome editing, etc., while breeding majorly constitutes
the indirect approach. With the advent of latest tools and technologies, these strategies could hasten the improvement of crop
species. Next-generation sequencing, high-throughput genotyping, precision editing, use of space technology for accelerated
growth, etc. had provided a new dimension to crop improvement programmes that work towards delivering better varieties
to cope up with the challenges. Also, studies have widened from understanding the response of plants to single stress to
combined stress, which provides insights into the molecular mechanisms regulating tolerance to more than one stress at a
given point of time. Altogether, next-generation genetics and genomics had made tremendous progress in delivering improved
varieties; however, the scope still exists to expand its horizon to other species that remain underutilized. In this context, the
present review systematically analyses the diferent genomics approaches that are deployed for trait discovery and improvement in major species that could serve as a roadmap for executing similar strategies in other crop species. The application,
pros, and cons, and scope for improvement of each approach have been discussed with examples, and altogether, the review
provides comprehensive coverage on the advances in genomics to meet the ever-growing demands for agricultural produce.
