Nature: Tolerance of phosphorus deficiency in traditional rice | Abiotic stress tolerance and GM crops | Scoop.it

Phosphorus is a limiting nutrient in soil, and globally. This new Nature article, by a group of researchers at the International Rice Research Institute (IRRI) and collaborators, identifies a gene from traditional rice varieties that confers tolerance to phosphorus limitation.

Furthermore,

"Here we show that overexpression of PSTOL1 in [modern] varieties significantly enhances grain yield in phosphorus-deficient soil. Further analyses show that PSTOL1 acts as an enhancer of early root growth, thereby enabling plants to acquire more phosphorus and other nutrients."
