Roots are pivotal for anchorage of land plants in the soil and for efficient uptake of water and mineral nutrients, thus playing a crucial role in plant fitness. The root system is composed of embryonic roots (primary root in Arabidopsis, primary and seminal roots in a few cereal crops) and...
(Reproduced from Taylor HM and Klepper B (1975) Water uptake by cotton root systems: an examination of assumptions in the single root model. Soil Science 120: 57–67.) In addition to an expression such as eqn [9], a second, similar type of equation can describe the flux over the root...

The gene acts by enhancing early root growth, conferring a globally larger root system to the plant, with enhanced root length and root surface area, contributing to an increased uptake of P, and of other nutrients (N and K). The gene is expressed in the zone of crown root initiation ...
The concept behind creation of tie-ridges is to optimize water infiltration, improvement of soil-water management, enhancement of root growth and nutrient uptake, and enhancement of rooting depth which is also supported by FAO (2000). Therefore, tie-ridge would play a significant role in productio...
The root system performs essential functions during plant development, including anchoring and water and nutrient uptake. For instance, a deep, thick, and branched root system is correlated with better survival under adverse conditions, such as water or nutrient deficits. The structure of a root sys...
(Figure1); in other words, roots are more water stressed than leaves. In the field, root also is the earlier organ under drought because plants uptake water through their roots. When soils become dry, roots sense this water deficit and produce chemical signals to transport to leaves via the...
Thus, using the water stable isotope-based multivariate linear mixed model, the current research is aimed at the quantitative investigation for root water uptake patterns of Nitraria, a prevalent desert shrub species in arid environments of Northwest China with an important windbreak and sand fixation...
We propose two possible explanation for this phenomenon: (1) a wider leaf area available for photosynthesis would produce higher amounts of photosynthates available to develop other organs; (2) a more complex root system would allow a more efficient water and nutrient uptake, allowing faster ...
N starvation during the establishment phase may have led to a limited link between shoot and root growth whereas in the second segment, the roots already profit from a higher N uptake resulting in a positive feedback from the shoot. This observation supports the hypothesis of de Kroon et al....
