Whole genome assembly of the Little Millet (Panicum sumatrense) genome: A climate resilient crop species

Abstract Little millet ( Panicum sumatrense ) belongs to one of the largest genera, Panicum comprising of 500 species that are distributed especially in tropical and sub-tropical Asia as well as Africa. This is a climate resilient crop that has the ability to adapt to adverse growing conditions, especially drought. Added to this is the better nutritional profile of little millet, which has higher iron and fibre contents as compared with rice. These characteristics make it an important crop species that would be pivotal for ensuring food security. Generating genomic resources for the species is significant and will have implications in crop improvement. Therefore, in the present study we report the de novo whole genome sequence of P. sumatrense . Long read sequencing and Hi-C based scaffolding resulted in a total of 279 scaffolds with N50 of 7.8Mb. The genome was annotated to predict protein coding genes and orthologous groups were analysed after comparison with various plant genomes. This high-quality genome assembly can be a valuable resource as future reference for genomic studies in this crop and related crop species.
