Oxygen isotopic composition (Δ18OLW) of leaf water can help improve our understanding of how anatomy interacts with physiology to influence leaf water transport. Leaf water isotope models of Δ18OLW such as the Péclet effect model have been develop

Yerba mate (Ilex paraguariensis) has both economic and cultural importance in South America. However, due to a lack of quality control during processing, adulteration can occur. The aim of the study was to measure adulteration of yerba mate brands ma

C4 grasses often outperform C3 species under hot, arid conditions due to superior water and nitrogen use efficiencies and lower rates of photorespiration. A method of concentrating CO2 around the site of carbon fixation in the bundle sheath (BS) is r

Diffusion of CO2 from the leaf intercellular air space to the site of carboxylation (gm ) is a potential trait for increasing net rates of CO2 assimilation (Anet ), photosynthetic efficiency, and crop productivity. Leaf anatomy plays a key role in th

Leaf carbon isotopic composition correlated well with transpiration efficiency, while leaf oxygen isotopic composition was confounded by leaf length in the C4 grasses Setaria viridis and Setaria italica.

Stable hydrogen isotope ratios of plant lignin methoxyl groups have recently been shown to record the hydrogen isotopic composition of meteoric water. Here we extend this technique towards tracing water source variations across a saltwater to freshwa

The oxygen isotope ratios of tree ring cellulose have a great potential as proxy for the oxygen isotope ratios of source water, which is related to climate. However, source water isotopic signatures can be masked by plant physiological and biochemica

Previous mangrove tree ring studies attempted, unsuccessfully, to relate the δ18O of trunk cellulose (δ18OCELL) to the δ18O of source water (δ18OSW). Here, we tested whether biochemical fractionation associated with one of the oxygen in the cellu

We studied the influence of environmental conditions in different vegetation types of the Brazilian savanna (cerrado s.l.) on CO 2 assimilation and water use efficiency of Styrax ferrugineus , S. camporum and S. pohlii , which are morphologically sim

Summary The current isotope tree ring model assumes that 42% of the sucrose oxygen exchanges with stem water during cellulose synthesis and that the oxygen isotope biochemical fractionation is c. 27‰. However, previous studies have indicated that t
