Abstract
AbstractSmall millets are known for their nutritional values, nutrient use efficiency, and extremely high levels of tolerance against abiotic stresses. Small millets exhibit a high level of molecular complexity due to their polyploidy nature and hence unraveling molecular networks controlling the above traits was challenging. Recent reports elucidated the role of noncoding RNAs (ncRNAs) in regulating an array of genes involved in stress tolerance and nutrient use efficiency traits. NcRNAs remained unexplored due to the lack of suitable platforms to identify, analyze, and characterize their expression. Advancements in Next Generation Sequencing and bioinformatics platforms have enabled the completion of several whole genome sequencing and transcriptome profiling projects in small millets that led to the discovery of a large number of ncRNAs and understanding of their expression and regulatory mechanism(s). This chapter discusses various classes of ncRNAs in small millets and their putative roles in modulating plant responses against drought, salt, cold, etc. Further, databases and online tools pertaining to the identification and analysis of Noncoding RNAs are presented.KeywordsSmall milletsNoncoding RNAsExpression profilingGene regulationBioinformatics toolsStress-responsive miRNA
