Revisiting the Decoded Genomes to Promptly Reveal their Genomic Perspectives

Post Arabidopsis thaliana, 55 genomes comprising 49 different plant species have been decoded by use of clone-by-clone, whole genome shotgun and next-generation sequencing approaches. The structural outcomes of these sequenced genomes shed light on their genomic constitution, particularly the way genes, transposable elements and genetic markers are orga-nized within the genomes. The functional outcomes provide a brief account of specific phenotypic trait characteristics of crop genomes by digging deep into the genetic make-up of transcription factors, regulato-ry elements and gene families governing multiple ag-ronomic traits in these crop plants. The comparative and evolutionary outcomes deduce the genetic basis of biological diversity and basic process of ge-nome evolution by analysing the syntenic relationships among genes and genomes/chromosomes of the se-quenced crop plants. Therefore, a revisit to published genome sequence landmarks in 30 major cultivated food crops constituting major groups (cereals, leg-umes, vegetables, fruits, oil seeds and fibres) would significantly assist us to gain a detailed insight into their genome organization and dissect the structural, functional, comparative and evolutionary intricacies for identifying species- and lineage-specific genes con-trolling multiple characteristics in crop plants. The es-sential inputs obtained will be helpful in devising efficient strategies to develop high-yielding climate-ready crop varieties through translational genomics.
