Description
Gul and colleagues published a 2026 study on a gene family that loosens plant cell walls in sorghum. Expansins let walls stretch so plants can grow and adapt to stress. Sorghum is a hardy grain, yet its expansin family had gone unmapped. The team catalogued the full set across the sorghum genome.
They found 68 expansin genes, mostly in two large subfamilies overall. Gene copies grew through both small and large duplications over time. Many expansins switched on strongly in roots and fast-growing tissues. Under drought tests, a subset rose sharply, confirmed by a second method. Three hub genes may lead breeding work for drought-tough sorghum. Wall loosening under drought may help roots keep drinking longer.
