The study looked at a family of proteins called PP2C in soybeans to understand their evolution and functions. They found 134 different PP2C proteins in soybeans, with many of them being duplicated through evolution. These duplicated genes have different roles now. Some genes were lost over time, especially in one subfamily. The PP2C proteins evolved at a slower rate compared to other genes. Some of these proteins are important for controlling plant growth and development. This information can be useful for improving soybean crops.
