Description
Yusuke Hoshino, Sachiko Horie, Masayuki Maki, and Ikumi Dohzono report a 2025 study on how a wild plant copes with pollen from a new kin species. Pollen from the wrong species can cut seed yield, yet plants that live near kin may have grown some guard over time. Proof from species with a known contact past is rare, so the team used two sorrel kin in Japan.
One sorrel is native and the other is a new arrival, and each grows both near and far from the other. Crosses with the wrong pollen cut seed yield in the native plant, most of all in groups that live near the kin. A second test, with right pollen first and wrong pollen next, also cut seed yield. The pattern defies the plain hope that near groups guard best.
