Panicum miliaceum
Information about Panicum miliaceum Genome
Broom millet (Panicum miliaceum), also known as common millet or proso millet, is a C4 grass species and an ancient tetraploid (2n = 4x = 36) with a genome size of approximately 887.8 Mb. It is primarily cultivated in resource-poor areas of Asia and Africa, particularly in northern China and eastern Europe, where it has been grown for approximately 10,000 years. Broomcorn millet serves as a staple food crop and is highly valued for its strong tolerance to abiotic stresses, such as drought, high salinity, and low water requirements, making it suitable for cultivation in marginal regions. A high-quality de novo genome assembly of broomcorn millet was achieved through a combination of PacBio sequencing, BioNano optical mapping, and Hi-C (in vivo) mapping[1]. The assembly spans approximately 848.4 Mb (N50 of ~8.24 Mb), covering ~95.6% of the estimated genome.

Genome Re-sequencing Projects and Variation Identification
Recently, 1,094 weedy and cultivated broomcorn millet accessions have been re-sequenced:
● 2024 - Lu et al. Genomic variation in weedy and cultivated broomcorn millet accessions uncovers the genetic architecture of agronomic traits[2].
We gathered these data, and present in the Genome Variation Map (GVM).
