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 field, and has already revealed some old secrets of submerged aquatic plants.

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...

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...

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...

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...

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...

Radial O2-loss barrier induction and arenchyma formation

Radial O2-loss barrier induction and arenchyma formationMany wetland species form both aerenchyma and a barrier to radial oxygen loss (ROL) in roots, which enhance...

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...

What creates Gentiana diversity in mountains?

The Qinghai-Tibetan Plateau (QTP) is extremely rich in species, but why? One recent explanation is the mountain‐geobiodiversity hypothesis (MGH) by Mosbrugger et...

How does variation in traits of Tunisian oak seeds affect survival?

Oaks are the dominant species of tree in many Mediterranean forests. However, the climate of the Mediterranean basin is predicted to change...

How Important Is Leaf Realism in Functional-Structural Plant Modelling?

Making a realistic plant in a computer model is possible, but is it necessary. All the computations generating the plant slow down...
