This artical summarized the research progress on hydrotropism of plant root system internationally from three aspects such as,how to induce hydrotropism by roots,root cap is the site of apperceiving humidity gradient,and the research on hydrotropism at the molecular level.
向水性对于陆地植物至关重要。
Roots tend to grow towards water in a soil, they show positive hydrotropism.
根的生长倾向于有水的土壤，表现出正向水性。
Growth or movement in a sessile organism toward or away from water, as of the roots of a plant.
