Description

Asselin and co-workers in Canada cleared up in 2026 which germ gene soybean plants truly spot when they fight off root rot. The rot germ, Phytophthora sojae, sheds switch proteins that plant guard genes can catch. One guard, Rps6, was long tied to a switch called Avr4/6. In soil hunts, the team found two odd germ strains where two near switch genes had swapped parts, a rare gene cross. That fluke let them split the pair.

Tests on plants with each guard told a clean tale. Just the form of the mate switch, Avr3c, matched which plants sickened or stood. In a leaf cell test, Avr3c alone set off the guard's kill call, while Avr4/6 did naught. Full gene reads of both strains mapped the swap end to end. The team names Avr3c the true match for Rps6, a fix that sharpens field tests for breed choice.
