Omics of Climate Resilient Small Millets

Abstract

Barnyard millet (Echinochloa spp) is a wide-adaptive crop that produces larger seeds compared to other minor millets. It is one of the most important minor millet crops that is predominantly cultivated for human consumption in Asia and livestock feed in the United States. Barnyard millet has incredible resilience to biotic and abiotic stresses. Grains are highly nutritious with significant amount of protein, carbohydrate, fiber, and, most notably, micronutrients (iron and zinc) than other staple cereals. Despite these benefits, barnyard millet has received little attention in genetic and genomic studies for many years. Progress has been made in develo** genetic and genomic resources over last few years, thanks to the reducing cost of sequencing technologies in polyploid and orphan millets species as well. Recently, the genome of wild and transcriptome sequences of cultivated Echinochloa species has facilitated the understanding of the genetic architecture of important agronomic and micronutrient traits. In this chapter, we discuss the importance of barnyard millet in the current climatic scenario and highlight the up-to-date status of genetic and genomics research and the research gaps that need to be addressed in this crop. This chapter also provides an overview of deploying omics approaches to study the barnyard millet for better understanding of crops’ nutritional richness and tolerance to environmental stresses.
