How to break down cell walls in sugarcane
One way of improving the usefulness of a plant crop might come not from studying where the plant cells grow, but where they die.

New CO2 microsensor reveals old secrets of plants
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...

CO2 and O2 dynamics in aquatic C3 or CAM plants
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...

Waterlogging tolerance in the forage legume Melilotus siculus
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...

Creative Destruction: How Death Leads to Function
Marcos Buckeridge explains how death and destruction in sugarcane roots can lead to the development of gas spaces, which improve root function.
Root cortical aerenchyma inhibits radial nutrient transport
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...

Your botanical ‘one-stop shop’
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...

Flooding tolerance in interspecific introgression lines in Zea
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
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...
Oxygen transport via aerenchyma in soybean
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...
