A WRKY transcription factor gene may be involved in regulating soybean seed size.

He Chaoying, a plant research team of the Chinese Academy of Sciences, has found for the first time that a WRKY transcription factor gene may be involved in regulating soybean seed size, which provides a new way of thinking for analyzing the genetic variation basis of soybean seed size and understanding the process and mechanism of soybean domestication.
results were published online online in the Journal of Experimental Botany.
found that the SoyWRKY15a gene, located in the seed size-related site range, was expressed differently between cultivated soybeans and wild soybeans. The
population analysis showed that the gene's position in cultivated soybeans and the sequence of bit coding regions in wild soybeans were exactly the same, but the expression of the former in the fruit was significantly higher than that of the latter, and the expression and regulation area of the latter were significantly related to the seed size, implying that the size of the regulated seeds.
further analysis found that the variation in the number of CT in soyWRKY15a's 5' non-translation zone affected its expression, while the variant pattern of the regulatory zone 1x indicates that the gene is likely to be associated with soybean domestication.
, according to the small editor, cultivated soybeans from wild soybeans domesticated.
soybean seeds have increased significantly during this domestication process, little is currently understood about the genetic variation that causes this difference.
