The study reveals the complex adaptive mechanisms of plants in response to water stress by deeply analyzing the physiological and molecular responses of rice roots and leaves under drought conditions. In terms of morphological structure adjustment, the root system optimizes water absorption by increasing length and root hair density, as well as adjusting growth strategies; Leaves reduce water evaporation by reducing surface area and adjusting stomatal density. At the molecular level, both roots and leaves exhibit similar and different gene expression patterns, involving pathways such as dehydration responsive element binding (DREB) signaling. Future research needs to address issues such as the interaction between root systems and soil microorganisms, differences in root systems among different rice varieties, and the molecular mechanisms of photosynthesis and transpiration. Through advanced molecular biology and genetic techniques, the search for new drought resistance genes is expected to provide scientific basis for drought tolerance breeding. Deeply exploring the molecular interaction network between roots and leaves will better elucidate the mechanism of rice's drought resistance and provide important support for the sustainable development of global agriculture.
