A Purdue University scientist has found a new soybean gene which can help in the development of newer types of the legume.

Jianxin Ma (Jen-Shin Ma), an assistant professor of agronomy, used the research model plant Arabidopsis thaliana to discover the soybean gene that controls whether the plant's stem continues to grow after flowering.

The find is a significant key to diversifying the types of soybeans growers can produce all over the world.

Ma said: "The approach that we used in this study proves to be promising for rapid gene discovery and characterization in soybean.

"With the genomic resources and information available, we spent only six months pinpointing and confirming the candidate gene - the time it takes to grow one generation of soybean."

Soybean plants generally fall into two categories: determinate plants whose main stem tips stop growing after flowering, and indeterminate plants that continue main stem growth after flowering.

In the United States, indeterminate soybeans are grown in the northern states, while determinate are grown in the southern states, Ma said.
