![]() Two clusters, which were inconsistent with the distribution of eco-geographical regions in China, were inferred from STRUCTURE, Neighbor-Joining, and principal component analysis, indicating a partially mixed distribution of Chinese green foxtails. A high degree of molecular diversity was detected in these accessions, with an average of 33.5 alleles per locus. In the present study, 288 green foxtail accessions, which were collected from all geographical regions of China, were analysed using 77 simple sequence repeats (SSRs) that cover the whole genome. As the ancestor of foxtail millet ( Setaria italica), an ancient cereal of great importance in arid regions of the world, green foxtail is crucial for the study of domestication and evolution of this ancient crop. Green foxtail ( Setaria viridis) is a new model plant for the genomic investigation of C4 photosynthesis biology. Jia, Guanqing Shi, Shenkui Wang, Chunfang Niu, Zhengang Chai, Yang Zhi, Hui Diao, Xianmin Molecular diversity and population structure of Chinese green foxtail revealed by microsatellite analysis. The implications of these findings for understanding the history of foxtail millet domestication and cultivation in ancient civilizations are significant. ![]() Our research gives a meaningful method of separating foxtail millet and green foxtail. Our results also revealed that the husk phytolith morphologies of foxtail millets from China and Eastern Europe are markedly different from those from Western Europe. This means certain morphotypes of phytoliths are relatively reliable tools for distinguishing foxtail millet from green foxtail. Discriminant function analysis reveals that 78.4% of data on foxtail millet and 76.9% of data on green foxtail are correctly classified. The size of ΩIII type phytolith of foxtail millet is bigger than that from green foxtail. Our research shows that the silicon structure of ΩIII from upper lemmas and paleas in foxtail millet and green foxtail can be correspondingly divided into two groups. In this paper, the silicon structure patterns in the glumes, lemmas, and paleas from inflorescence bracts in 16 modern plants of foxtail millet and green foxtail from China and Europe are examined using light microscopy with phase-contrast and a microscopic interferometer. Phytolithic analysis provides a meaningful method for identifying this important crop. Phytolith Analysis for Differentiating between Foxtail Millet ( Setaria italica) and Green Foxtail ( Setaria viridis)įoxtail millet ( Setaria italica) is one of the oldest domesticated cereal crops in Eurasia, but identifying foxtail millets, especially in charred grains, and differentiating it from its wild ancestor, green foxtail ( Setaria viridis), in the archaeobotanical remains, is still problematic. ![]() Zhang, Jianping Lu, Houyuan Wu, Naiqin Yang, Xiaoyan Diao, Xianminįoxtail millet ( Setaria italica) is one of the oldest domesticated cereal crops in Eurasia, but identifying foxtail millets, especially in charred grains, and differentiating it from its wild ancestor, green foxtail ( Setaria viridis), in the archaeobotanical remains, is still problematic.
