“…Thus, herbicide-resistant soybeans are the most likely to be grown commercially on a large scale in China . During transgenic soybean cultivation, exogenous genes can pose some environmental risks such as the resistance development of target-organisms and gene flow to wild relatives and other cultivated varieties via pollen. , The United States, Brazil, and Argentina, where GM soybeans are grown on a large scale, do not have natural wild soybean populations, as opposed to China, where many grow very close to soybean fields . Wild soybean has good environmental adaptability as well as salt, drought, and nitrogen stress tolerance, making it essential for the study of soybean evolution. , As cultivated soybean is a domesticated and improved version (Glycine soja, 2 n = 40, GC), the two provide a basis for studying genes under natural versus farmland conditions .…”
