Article Synopsis
- A major gene locus, SC9.1, was identified as the key regulator of brown seed color in broomcorn millet, a cereal crop known for its diverse seed colors.
- Through genetic mapping and analysis of crossbred populations, researchers found that the trait is controlled by a single dominant locus located on chromosome 9.
- The gene longmi004412 was pinpointed as the specific gene responsible for the brown seed coloration, paving the way for future advancements in crop breeding and genetic research.
Article Synopsis
- The study analyzed the GRF family genes in broomcorn millet using bioinformatics and transcriptome sequencing, revealing that there are 21 GRF genes unevenly distributed across 12 chromosomes.
- The PmGRF proteins range from 224 to 618 amino acids in length and are located primarily in the nucleus, with evidence of varying expression levels tied to different plant heights.
- Seven specific GRF genes were identified as influential in broomcorn millet plant height, as their expression levels differed between a dwarf variety and a tall variety at key growth stages.
Article Synopsis
- Two key genetic loci related to tiller and axillary branch numbers in foxtail millet were pinpointed: qTN5.1 for tiller number and qAB9.1 for axillary branches, with candidate genes identified in specific mapped regions.
- The study utilized a foxtail millet cultivar and its wild relative, Setaria viridis, to explore how these traits impact plant structure and biomass through constructing segregating populations.
- Through transcriptome analysis and bulk segregant analysis, important genes involved in vegetative branching were found, potentially aiding in breeding efforts for more desirable foxtail millet varieties.
Broomcorn millet (Panicum miliaceum L.) is an orphan crop with the potential to improve cereal production and quality, and ensure food security. Here we present the genetic variations, population structure and diversity of a diverse worldwide collection of 516 broomcorn millet genomes.

However, the genes underlying the regulation of plant height in broomcorn millet are rarely reported. Here, an F population derived from a cross between a normal variety, "Longmi12," and a dwarf mutant, "Zhang778," was constructed.

Identification of QTL responsible for morpho-agronomic and yield-related traits facilitates dissection of genetic control and breeding in cereal crops. Here, based on a Yugu1 × Longgu7 RIL population and genome-wide resequencing data, an updated linkage map harboring 2297 bin and 74 SSR markers was constructed, spanning 1315.
View Article and Find Full Text PDFBackground: Foxtail millet (Setaria italica) has been developed into a model genetical system for deciphering architectural evolution, C photosynthesis, nutritional properties, abiotic tolerance and bioenergy in cereal grasses because of its advantageous characters with the small genome size, self-fertilization, short growing cycle, small growth stature, efficient genetic transformation and abundant diverse germplasm resources. Therefore, excavating QTLs of yield component traits, which are closely related to aspects mentioned above, will further facilitate genetic research in foxtail millet and close cereal species.
Results: Here, 164 Recombinant inbreed lines from a cross between Longgu7 and Yugu1 were created and 1,047,978 SNPs were identified between both parents via resequencing.
