Outline of Final Research Achievements

Since the lateral root primordium size is a major factor that determines the root system morphology and regulates the water absorption capacity under drought stress, it is extremely important for stable rice production under a poor environment to elucidate the control mechanism of the lateral root primordium size. Here, we tried to characterize some rice mutants that produce big size of lateral root primordia and isolate and analyze each mutant’s causative gene. As a result, it was clarified that changes in cell wall extensibility and auxin localization are involved in the control of lateral primordium size.

Academic Significance and Societal Importance of the Research Achievements

近年、世界的な干ばつが頻発する中、根系改良による耐乾性育種が注目されている。本研究の成果から、イネの根系形態を可塑的に変化させる能力を強化し、乾燥ストレス耐性に優れる品種を作出する上での有用な手がかりが得られた。
