The study found that there are parallel genetic choices in domestication of different crops

hypnotic regulatory gene G was selected in parallel in soybeans and rice. Map from the Institute of Genetic Development of the Chinese Academyusing genome-wide association analysis, the researchers identified for the first time the G gene that specifically controls the skin green of soybean species. Interestingly, subsequent studies have found that the G gene is strongly selected during the domestication of soybeans, and that wild soybeans are all G allied variants that control green skin. Because the green color of wild soybeans is obscured by black, it is not possible to choose wild soybeans based on the color of the skin, so the researchers speculate that G may also be involved in regulating other important domestication symptoms.
researchers further found that the G gene that controls the green skin of soybean seeds is also involved in regulating soy seed sleep. In addition, G and its congener genes were selected during the domestication of soybeans, rice and tomatoes, and were involved in the regulation of seed sleep in soybeans, rice and athropomorthic mustard.
the study first reported that the G gene that regulates seed sleep is selected in parallel in the domestication of different crops, the first gene to be reported to be selected in parallel in the domestication of multiple crops. Based on this, the researchers believe that when people domesticate a new species, they may first consider changing these genes, which are selected in parallel, to optimize their regulated agro-artistic features, in order to speed up domestication.
, crop domestication is the origin of modern agriculture, which is of great significance to the development of agriculture. In the process of domestication of different crops from wild to cultivated species, some agronomous features show the phenomenon of convergence and domestication, such as the disappearance of granulation, the coarseness of stems and stems, the enhancement of top advantage, and the weakening of seed sleep. Whether the genes that control these features are chosen in parallel in the domestication of different species has always been an important scientific proposition in evolutionary research.
