From: Selection for Oil Content During Soybean Domestication Revealed by X-Ray Tomography of Ancient Beans
(a) Seven archaeological soybeans from different periods and three modern soybeans are compared with each other and with modern water-saturated (MS), modern cultivated (MC) and modern wild (MW) soybeans. The blue shading separates the data into two: modern cultivated and wild soybean and archaeological soybeans S1 and S4 in the upper region, and others in the lower region. (b) Compares modern cultivated and wild soybeans, S2 and S3. The negative correlation between the oil and protein content of S2 and S3 is indicated. Modern cultivated soybean has a higher oil content than the modern wild seed. (c) Three Longshan period soybeans: S4–6. A negative correlation between the oil and protein content is indicated in S5 and S6. However, S4 shows an unusual distribution.
