Abstract：
Sugars derived from photosynthesis, specifically sucrose, are the primary source of plant energy. Sucrose is produced in leaves and transported to the roots through the phloem, serving as a vital energy source. Environmental conditions can result in higher or lower photosynthesis, promoting anabolism or catabolism, respectively, thereby influencing the sucrose budget available for roots. Plants can adjust their root system to optimize the search for soil resources and to ensure the plant\'s adaptability to diverse environmental conditions. Recently, emerging research indicates that SNF1-RELATED PROTEIN KINASE 1 (SnRK1), trehalose 6-phosphate (T6P), and TARGET OF RAPAMYCIN (TOR) collectively serve as fundamental regulators of root development, together forming a signaling module to interpret the nutritional status of the plant and translate this to growth adjustments in the below ground parts.
摘要：
来自光合作用的糖，特别是蔗糖，是植物能量的主要来源。蔗糖在叶片中产生，并通过韧皮部输送到根部，作为重要的能源。环境条件可以导致更高或更低的光合作用，促进合成代谢或分解代谢，分别,从而影响根可用的蔗糖预算。植物可以通过调整根系来优化土壤资源的寻找,保证植物对不同环境条件的适应性。最近,新兴研究表明，SNF1相关蛋白激酶1(SnRK1)，海藻糖6-磷酸（T6P），和Rapamycin（TOR）的目标共同充当根系发育的基本调节剂，一起形成一个信号模块来解释植物的营养状况，并将其转化为地下部分的生长调整。
