Abstract:
... Resurrection plants are unique among higher plants because of their ability to withstand long periods of dehydration without damages. In this study, leaf epidermis and palisade mesophyll of three resurrection species, Haberlea rodopensis, Ramonda serbica and Ramonda myconi, grown under full desiccation and benign conditions, were analyzed by differential interference contrast microscopy. Detailed ...

Abstract:
... Isoflux-based isotopic flux partitioning (isoflux-based IFP) separates net ecosystem exchange flux (NEE) into net photosynthesis (FA) and nonfoliar respiration (FNR), and avoids the spurious correlation of component fluxes found in statistical flux partitioning. Canopy photosynthetic discrimination (Δcanopy) is a key variable in isoflux-based IFP, but it ignores diffusional and respiratory fractio ...

Abstract:
... C₃ photosynthesis is often limited by CO₂ diffusivity or stomatal (gₛ) and mesophyll (gₘ) conductances. To characterize effects of stomatal closure induced by either high CO₂ or abscisic acid (ABA) application on gₘ, we examined gₛ and gₘ in the wild type (Col‐0) and ost1 and slac1‐2 mutants of Arabidopsis thaliana grown at 390 or 780 μmol mol⁻¹ CO₂. Stomata of these mutants were reported to be in ...

Abstract:
... Plant aquaporins constitute a large family of proteins involved in facilitating the transport of water and small neutral molecules across biological membranes. In higher plants they are divided into several sub-families, depending on membrane-type localization and permeability to specific solutes. They are abundantly expressed in the majority of plant organs and tissues, and play a function in pri ...

Abstract:
... Various environmental variables interact with UV-B radiation (280–315 nm), among them temperature. In many plants epidermal UV screening is induced by low temperature even in the absence of UV irradiation. On the other hand, low temperature can aggravate damage caused by UV-B radiation. We investigated the interaction of UV-B radiation and low temperature in Arabidopsis thaliana (L.) Heynh. Exposu ...

Abstract:
... Fresh leaf spectral reflectance is primarily influenced by leaf water content and structural aspects such as the inter-cellular spaces within the spongy mesophyll, which also interfere with the estimation of the leaf nitrogen content. It is therefore essential to identify spectral bands that are least affected by the above perturbing factors for improving leaf nitrogen estimation for fresh leaves ...

Abstract:
... Quantification of leaf respiration is important for understanding plant physiology and ecosystem biogeochemical processes. Leaf respiration continues in the light (RL) but supposedly at a lower rate than in the dark (RDₖ). However, there is no method for direct measurement of RL and the available methods require nonphysiological measurement conditions. A method based on isotopic disequilibrium qua ...

Estimates of mesophyll conductance (gm), when calculated from chlorophyll fluorescence, are uncertain, especially when the photosystem II (PSII) operating efficiency is measured from the traditional single saturation pulse methodology. The multiphase flash method has recently been recommended to replace the single saturation pulse method, allowing a more reliable estimation of gm. Also, many resea ...

Abstract:
... Mesophyll conductance (gₘ) is known to affect plant photosynthesis. However, gₘ is rarely explicitly considered in land surface models (LSMs), with the consequence that its role in ecosystem and large‐scale carbon and water fluxes is poorly understood. In particular, the different magnitudes of gₘ across plant functional types (PFTs) are expected to cause spatially divergent vegetation responses t ...
