how do roots control water uptake Roots serve a vital role among other functions in extracting water from the soil transporting it to the shoot and sustaining transpiration To fulfill this function
Plant roots mediate water uptake from the soil and have developed a number of adaptive traits such as hydrotropism to aid water foraging Hydrotropism Most plants secure the water and minerals they need from their roots Water moves from the soil to the roots stems and ultimately the leaves where transpiration occurs The roots absorb enough water to

Root hairs connect roots to the soil extend the effective root radius and greatly enlarge the absorbing surface area Although the efficacy of root hairs in nutrient We emphasize root water uptake and transport as the gateway for plant water supply complementing traditional emphases on shoot processes and stomatal
We review how aquaporins can play an important role in affecting root water transport properties hydraulic conductivity Lp and thus alter water uptake plant water The root system is the first actor for plant water uptake through its spatial architecture and the distribution of hydraulic conductance along root axes and branching orders

The model allows for a high capability of roots to take up water in the presence of high rates of transpiration high demands for water from the shoot By This Perspective explores how water availability regulates root architecture and water transport capacity hydraulics from sensing mechanisms to novel responses
At the single root scale local soil hydraulic status and plant physiology strongly control water uptake At the whole root system level these local spatially interacting processes Water is lost from the leaves via transpiration approaching p 0 MPa at the wilting point and restored by uptake via the roots A plant can manipulate p via its ability to manipulate s and by the process of

how do roots control water uptake - In particular it is shown that the differential soil drying produced by diurnal root water uptake drives a significant upward redistribution of moisture both through a
