The mechanistic understanding of isotope fractionation processes is increasing but we still
lack detailed knowledge of the processes that determine the isotopic composition of the tree …

In the last decade, our understanding of the processes underlying plant response to drought,
at the molecular and whole-plant levels, has rapidly progressed. Here, we review that …

▪ Abstract The use of stable isotope techniques in plant ecological research has grown
steadily during the past two decades. This trend will continue as investigators realize that …

A mechanistic model is presented to quantify both the physical and biochemical fractionation
events associated with hydrogen and oxygen isotope ratios in tree-ring cellulose. The model …

Based on measurements of δ 18 O and δ 13 C in organic matter of C 3-plants, we have
developed a conceptual model that gives insight into the relationship between stomatal …

With the development of rapid measurement techniques, stable oxygen isotope analysis of
plant tissue is poised to become an important tool in plant physiological, ecological …

We compiled hydrogen and oxygen stable isotope compositions (δ2H and δ18O) of leaf
water from multiple biomes to examine variations with environmental drivers. Leaf water δ2H …

A small proportion of water molecules contain the heavier isotopes of hydrogen and oxygen.
There is a tendency for these heavier molecules of water to accumulate in leaves during …

Cotton (Gossypium hirsutum L. cv. CS50) plants were grown at two levels of relative
humidity (RH) and sprayed daily with abscisic acid (ABA) at four concentrations. Plants …

Within the realm of the newly evolving discipline of environmental sciences, the stable-
isotope methodology is being used to an ever-increasing extent, especially in the study of …
