Abstract excerpt

KEY MESSAGE: qRN5a, a novel QTL for increasing root number under low K in rice, was fine mapped to a 48.8-kb region on chromosome 5, and LOC_Os05g27980 is the most likely candidate gene. Potassium (K) is a mineral nutrient essential for plant growth and development, but the molecular mechanism for low-K (LK) tolerance in rice remains poorly understood. In our previous study, the quantitative trait locus (QTL)...
