Abstract:
... BACKGROUND: In explaining and predicting spatial vegetation patterns, ecologists have increasingly favoured the use of climatic water balance variables, including actual evapotranspiration (AET) and climatic water deficit (CWD), for representing the hydrologic and energetic environment experienced by plants. Much of the interest in these variables lies in their hypothesized potential to characteri ...

Abstract:
... Elevated atmospheric O₃ can inhibit the growth rate of various plants and increase metal content in their tissues owing to the oxidative damage, thereby affecting their phytoremediation efficiency. In this study, a series of O₃ fumigation treatments were designed to evaluate the dry weight, Cd content, and transpiration rate responses of Celosia argentea to different levels of O₃ (40, 50, 55, 60, ...

Abstract:
... Plant water isotopic compositions are widely used to describe patterns of soils water uptake. Although valuable, the technique only provides relative uptake distributions, which can be misleading. Without information on total transpiration, the technique cannot address central questions on drought response, competition, and species coexistence. ...

Abstract:
... Stomata control carbon and water vapor exchange between the leaves and the atmosphere, thus influencing photosynthesis and transpiration. Combinations of forest patches with different stand ages are common in nature, however, information of which stomatal traits vary among these stands and how, remains limited. Here, seven different aged forest stands (6, 14, 25, 36, 45, 55, and 100 years) were se ...

Active growth of tiller bud (TB) requires high amount of mineral nutrients; however, the mechanism underlying the distribution of mineral nutrients to TB with low transpiration is unknown. Here, we found that the distribution of Zn to TB is mediated by OsZIP4, one of the ZIP (ZRT, IRT‐like protein ...

We hypothesized that leaf hydraulic architecture may affect the degree to which gradients in H₂¹⁸O develop within leaves, influencing bulk leaf stable oxygen isotope enrichment (ΔL) and the degree to which the Péclet effect is relevant in leaves. Leaf hydraulic design predicted the re ...

In general, these strategies can be defined along a plant economics spectrum, which classifies plants depending on whether their growth rate is fast or slow, where fast growth is associated with high mortality, high water use, and high sensitivity to drought. Which strategy along this economy spectrum will be selected under different p ...
