Description
Jingwen Yu and a large team hunt for rice genes that leave plants open to root-knot worms, publishing their findings in 2026. The worm Meloidogyne graminicola bores into rice roots and cuts yields across Asia, yet few resistant rice types are known. Genome-wide scans, multi-layer molecular data, and gene tests pointed to a factor named Rsf1, which codes a small cysteine-rich protein. A single letter change in the gene's switch region separated types by risk.
Plants with the risky letter made much more Rsf1 once worms attacked, while the safer letter kept levels low and plants held up better. A regulator called Myb44 was shown to drive Rsf1 output. Knocking the gene out in rice and in a model weed both raised resistance, pointing to a shared weakness that breeders could target.
