Simulated Herbivory Leads Grasses to Pass Fungal Symbionts to Their Offspring

Many grasses host symbiotic fungi, Epichloë spp. These fungi can help grasses tolerate herbivory, or help repel herbivores. But how do these...

Thismia and its unusual number of specialist relationships.

Plants sometimes specialise. Catering for a specific partner can ensure a reliable source of food or pollination. At the same time, relying on that...

What can you do with a holobiont?

It's said all plants are holobionts. If that's true why bother creating a new word? What value does the word holobiont bring that plant doesn't already have?

Effects of plant polyploidy on the legume-rhizobia mutualism

Polyploidy alters plant genomes, phenotypes, and abiotic interactions. The effects of polyploidy on plant-biotic interactions however are less well known. One important plant-biotic interaction is...

Plectocarpon lichenum: the parasite that makes itself comfortable when it moves into a lichen

What happens when an unwanted visitor infects a lichen? Plectocarpon lichenum makes it harder for its host to eject it.

How do you grow a palm? The secret’s in the soil.

An investigation on a tiny island reveals that microscopic fungi can dictate the destiny of giants, opening the possibility of mycorrhizal-driven speciation.

The lachrymatory tale of the barnacle and the bacterium

For Valentine's Day Nigel Chaffey finds a tale of an unlikely couple who have set up home together, though it ends in tears.

Antarctic endophytes improve drought tolerance in lettuce plants

Climate change has limited the availability of water for irrigating crops throughout many regions of the world. Indeed, current models of climate change predict...

Mycorrhizal fungi and distribution of specialized orchids

The use of a widespread fungal operational taxonomic unit in P. deformis enables a broad distribution despite high mycorrhizal specificity.

A mutualistic endophyte alters the niche dimensions of its host plant

Mutualisms can play important roles in influencing species coexistence and determining community composition. However, few studies have tested whether mutualisms may affect species distributions...

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....

How do you get more DNA down a pollen tube?

A common event for flowering plants is whole genome duplication (WGD), where a plant gets extra chromosomes. It’s often studied in mature...

Simulating the effects of local adaptation and life history on the ability of plants to track climate shifts

Local adaptation is common but not universal in plants and results from the interplay of gene flow with natural selection. Gene flow...
