Evolution and diversity of CO2 concentrating mechanisms in cyanobacteria.
Cyanobacteria have developed an effective photosynthetic CO2 concentrating mechanism (CCM) for improving the efficiency of carboxylation by a relatively inefficient Rubisco. The development of thisExpand
Tobacco aquaporin NtAQP1 is involved in mesophyll conductance to CO2 in vivo.
Leaf mesophyll conductance to CO(2) (g(m)) has been recognized to be finite and variable, rapidly adapting to environmental conditions. The physiological basis for fast changes in g(m) is poorlyExpand
The Arabidopsis thaliana aquaporin AtPIP1;2 is a physiologically relevant CO₂ transport facilitator.
Cellular exchange of carbon dioxide (CO₂) is of extraordinary importance for life. Despite this significance, its molecular mechanisms are still unclear and a matter of controversy. In contrast toExpand
Function of Nicotiana tabacum Aquaporins as Chloroplast Gas Pores Challenges the Concept of Membrane CO2 Permeability[W]
Photosynthesis is often limited by the rate of CO2 diffusion from the atmosphere to the chloroplast. The primary resistances for CO2 diffusion are thought to be at the stomata and atExpand
A new measurement technique reveals rapid post-illumination changes in the carbon isotope composition of leaf-respired CO2.
We describe an open leaf gas exchange system coupled to a tunable diode laser (TDL) spectroscopy system enabling measurement of the leaf respiratory CO(2) flux and its associated carbon isotopeExpand
The physiological basis for genetic variation in water use efficiency and carbon isotope composition in Arabidopsis thaliana
Ecologists and physiologists have documented extensive variation in water use efficiency (WUE) in Arabidopsis thaliana, as well as association of WUE with climatic variation. Here, we demonstrateExpand
Do bryophyte shoot systems function like vascular plant leaves or canopies? Functional trait relationships in Sphagnum mosses (Sphagnaceae).
Vascular plant leaf traits that influence photosynthetic function form the basis of mechanistic models of carbon exchange. Given their unique tissue organization, bryophytes may not express similarExpand
Evolutionary significance of isopreneemission from mosses.
Isoprene emission has been documented and characterized from species in all major groups of vascular plants. We report in our survey that isoprene emission is much more common in mosses and fernsExpand

The Chlamydomonas reinhardtii cia3 Mutant Lacking a Thylakoid Lumen-Localized Carbonic Anhydrase Is Limited by CO2 Supply to Rubisco and Not Photosystem II Function in Vivo
The Chlamydomonas reinhardtii cia3 mutant has a phenotype indicating that it requires high-CO2 levels for effective photosynthesis and growth. It was initially proposed that this mutant was defectiveExpand
