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

Mistletoe-ing around the tree reduces growth in forests

It might seem romantic, but the last thing a tree wants is an embrace under mistletoe.

Bamboosting growth: why does bamboo grow so fast?

What is it that gives bamboo its rapid growth? One team has been looking for the answer not with the fastest plants, but with the slower variants to see what they lack.

Too much tubulin flips cell wall flexibility

Joseph Stinziano investigates how something you might find in jam controls how easily trees open or close access their leaves.

Where is the water? A new way to ‘see’ the water in tall trees

Water flows down, so how can even the tallest trees draw it up to the top of the canopy?

Recovering from winter: how conifers overcome their own seasonal affective disorder

Evergreen conifers face a unique challenge during winter: it is too cold for photosynthesis, but their leaves still absorb light energy. This can be...

Growing after attack: what predicts tree responses to herbivores?

Trees can face significant threats from herbivores, particularly ones that defoliate (i.e. eat leaves and reduce leaf area). After being attacked by defoliators, trees...

A forester’s guide to productivity: predicting the largest trees

Trees have been, are, and will continue to be a valuable renewable resource for myriad products from construction materials to books. To keep up...

Becoming a better locksmith: a new method speeds up our ability to unlock secrets of past climates

Chemical isotopes in tree rings can help us learn about past environments, but how can you extract them without interfering with measurements?

Could drought stress in trees affect air quality?

With climate change, trees will experience an increased frequency of stress events (i.e. drought, heat stress) causing both direct effects (e.g. CO2 uptake through...

To cope, or not to cope: tropical rainforest tree leaves show little response to drought

Drought will become more severe in tropical rainforests as climate change continues. This could cause widespread tree mortality in these forests, unless the trees...

A scorched leaf policy? A mangrove tree uses oxidative stress against an insect pest

One major pest of mangrove forests in China is a leaf-mining insect, which burrows into the upper layer of the leaf. Insect attack not...

New grapevine model better predicts whole-canopy gas exchange

Models considering only the maximum photosynthetic capacity for all leaves over-estimated net carbon dioxide exchange by nearly a third.

Phylogeny, age and adaptive evolution of genus Allium

The genus Allium L., one of the largest monocotyledonous genera and one that includes many economically important crops with nutritional and medicinal...

Plants from different climates can react to drought in similar ways

How do plants react when circumstances change? One method can be to evolve a local adaptation. Another can be be phenotypic plasticity,...

Not All Pine Needles Are Identical: Lower Crown Loss in Pinus radiata

When fungal infection comes to Pinus radiata, it can run through the bottom of the crown of the tree, removing its leaves....
