Chromosome region for high hydraulic conductance in rice

Chromosome region for high hydraulic conductance in rice

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
