Ovule and seed production patterns in relation to flower size and floral symmetry
Animal pollinated flowers show two types of floral symmetry, actinomorphy (radial symmetry) with several planes of symmetry or zygomorphy (bilateral symmetry) with just one symmetry plane.

Strigolactones interact with other plant hormones in many situations
Strigolactones are interesting phytohormones in their own right, but Luke Omoarelojie and colleagues say we should be looking at cross-talk with other hormones too.

Drying out defenses: drought reduces tree defense system
Drought stress is becoming increasingly common with climate change, with negative impacts on tree growth and survival. The mechanisms of drought mortality in trees are often

A tome for the phloem: Tree Physiology’s Special Issue on Phloem
Phloem is a crucial tissue in trees, responsible for transporting carbon and cycling of nutrients throughout the plant. However, there is comparatively little information on phloem

Waking up to respiration: leaf respiration in the light alters our interpretation of ecosystem carbon fluxes
In plants, respiration is usually inhibited in the light compared to the dark. Measuring respiration in the light is particularly difficult, because photosynthesis and photorespiration are

Fueling the fire – how is stem growth respiration linked to stem growth?
Understanding how forests grow and how they metabolize carbon is crucial to ecosystem carbon flux, feedbacks between vegetation and climate, and the forestry. However, a key

Can less water mean tastier herbs?
We all love fresh herbs for cooking – but are they sustainable? Latest research shows that the water footprint of potted herbs can be reduced and at the same time, flavour and quality improved

Trading food for water – trees exude more carbon under drought stress
Plants secrete carbon compounds into soils through their roots, affecting microbes in such a way that nutrient availability in the soil can increase. This root exudation

Pining for resistance: a new way to assess pine susceptibility to fungal diseases
McAllister et al. demonstrate the utility of rh-qPCR to quantify ophiostomoid fungi in situ from MPB and pine DNA extracts

The benefits of sleeping in
The early bird catches the worm, but does the frost catch the early plant? A new article in AmJBot says there are advantages for a plant to germinate late.

Pollution isn’t always good for trees
You might be surprised that it has any positive effects, but anthropogenic Nitrogen has been boosting the nutrients for sugar maples in Michigan. But these benefits are likely to be lost in the future due to rising CO2 concentrations.
