A single soybean gene shapes branching and regional adaptation

Crop Improvement

If you've ever wondered why a soybean or bean variety that thrives in one garden zone sprawls or stays stunted in another, this gene helps explain how plants tune their shape to local day length.

Soybean plants grown near the equator look different from those grown farther north, partly because of a gene called TMS6 that controls branching. Researchers found that natural variants of this gene, which likely respond to day length, help soybean plants adjust their growth habit to match the latitude they're grown in. This gives breeders a genetic marker they can use to design soybean varieties suited to specific regions.

Key Findings

1

TMS6 gene variants regulate branching architecture in soybean plants

2

Natural allelic diversity at the TMS6 locus correlates with the latitude where soybean landraces originated

3

Findings provide a candidate gene target for breeding regionally adapted soybean varieties

chevron_right Technical Summary

Scientists identified a soybean gene called TMS6 that controls how much a plant branches, and different natural versions of this gene help soybean varieties thrive at different latitudes, offering breeders a tool to design better-adapted crop varieties.
