Re: Collab Digest, Vol 49, Issue 4
What do you think we should call "little" millet? Thank you Don for alerting us to new genetic developments of little millet. Outside this correspondence community, "little" millet discussions can be extremely confusing. Foxtail millet seeds are a third the size of proso, and proso is considered a small seed. "Little" millet has even smaller seed than foxtail. We need nomenclature so the public can identify different millets. Proso, although an odd word, seems appropriate. Foxtail millets, I suggest, we should refer to as "Italian" millets taken from the Latin name, Setaria italica. (German R is a commonly planted variety, but calling foxtail millet "German" millet would be even more confusing.) Since "little" millets have at least nine different names, in various languages seven begin with "S." They are Shavan, Sama, Saamai, Samalu, Sava, Suan, Saame, and I might as well throw in the Malayalam "Chama" (which could sound like and "S"). Therefore, I propose we standardize an English name for "little" millet beginning with the letter "S." Topic is open to all. What do you think we should call "little" millet?....Gary Wietgrefe On Sun, Feb 15, 2026 at 5:00 PM <collab-request@lists.millets2023.space> wrote:

A near-complete genome of little millet (Panicum sumatrense) has been decoded by an Indo-Canadian team led by the ICAR - Indian Institute of Millets Research's Global Centre of Excellence on Millets.
Little millet is an allotetraploid, like its cousin, proso or broomcorn millet (P. miliaceum), meaning that it has two sets of chromosomes. That evolution would have long predated its domestication, which occurred prior to the Early Harappan period in the Indus valley region some 5000 years ago.

Abstract from the research article:
"Little millet is a hardy and nutrient-rich cereal which improves food and nutritional security in marginal environments. Despite its importance, genomic resources for this orphan crop have been limited. Here, we report a high quality, chromosome-scale genome assembly of little millet comprising 18 chromosomes and 59,045 genes. Eleven chromosomes are assembled from telomere to telomere, revealing an 850 Mb tetraploid genome that closely resembles broomcorn millet. Comparative analyses indicate early stages of diploidization, characterized by gene loss and subgenome-specific expression biases that vary across genes and tissues. Resequencing of 300 accessions uncovers extensive genetic diversity, including single-nucleotide polymorphism and structural variants. Genome-wide association studies identify genetic loci linked to grain micronutrient traits, including several associated with high iron content. These genomic and phenotypic resources provide a foundation for molecular breeding and marker-assisted selection, enabling the improvement of little millet as a climate-resilient crop to support global food and nutritional security."
Other institutional partners in the research include University of Saskatchewan, National Research Council Canada / Conseil national de recherches Canada, and University of Agricultural Sciences, Bangalore.
