The rate of photosynthesis in paddy rice, Oryza sativa, often decreases around noon on sunny days because of water stress even under submerged conditions. Adachi et al. study a high-yielding indica variety with a relatively high hydraulic conductance in comparison with a standard, lower-yielding japonica variety, and find that a greater root surface area is responsible for the higher water uptake. They detect a chromosome region associated with this trait between RM3916 and RM2431 on the long arm of chromosome 4
