Description
Benjamin Wee Y and colleagues map gene networks that help hemp cope when phosphorus runs short. Phosphorus is a core plant nutrient, and hemp, shaped by centuries of human selection for fiber and seed, handles poor soils better than many crops. Their 2026 study grew hemp under rich and poor phosphate supply and read gene activity across roots, leaves, and other organs, then grouped genes that rose and fell together.
Twelve gene groups appeared, tied to jobs such as root growth, fiber making, and flowering. Two groups, one in leaves and one in roots, tracked the plant's phosphorus state closely, and both overlapped with genes marked by domestication. A gene called SPX3 sat at the hub of the leaf response, while root shape changes ran through known regulator families. Hormones called strigolactones also steered the root response.
