We have constructed a new CO2 microsensor with a tip diameter as small as the thinnest of human hairs. This new microsensor can be positioned in plant tissues in controlled laboratory experiments as well as in the...
Pedersen et al. describe a new amperometric CO2 microsensor and an O2 microsensor elucidated the dynamics in leaf pCO2 and pO2 during light–dark cycles for C3 Lobelia dortmanna (Campanulaceae) and CAM Littorella...
Messina (Melilotus siculus, Fabaceae) is a waterlogging-tolerant annual forage legume, but data were lacking for the effects of waterlogging on nodulated plants reliant on N2 fixation. Konnerup et al. find that plants...
Root cortical aerenchyma (RCA) provides an adaptation to low nutrient availability by reducing the metabolic cost of soil exploration. Hu et al. use radiolabelling to investigate uptake of phosphate, sulphate and...
There are plant biology journals that seem to concentrate on a single taxon (you know the ones I mean!) – e.g. The Plant Journal and The Plant Cell. There are others devoted to the molecular biology of plants, such as...
Nicaraguan teosinte Zea nicaraguensis, a species found in frequently flooded areas, is useful germplasm for breeding flooding-tolerant maize. Mano and Omori select flooding-tolerant lines using a library of...
Radial O2-loss barrier induction and arenchyma formation Many wetland species form both aerenchyma and a barrier to radial oxygen loss (ROL) in roots, which enhance internal O2 diffusion to the root apex. Shiono et al...
When in flooded soil, soybean, Glycine max, produces aerenchyma and hypertrophic stem lenticels. Shimamura et al. (pp. 277–284) investigate the oxygen dynamics in these tissues and find that hypertrophic lenticels on...
