PtHMGR overexpression enhances tolerance of salt and drought

Overexpression of PtHMGR enhanced the stress resistance of poplar.

Where did the first flowers grow?

Botanists have tried to understand the conditions that led to the evolution of the first flowers by reconstructing the niches from which the earliest flowering plants diverged.

What factors make a deadly carrot so dangerous?

The deadly carrot might sound as likely as the killer tomato, but decoding the defences of Thapsia garganica might have a big pay-off in the future.

A new study reveals how the cuticle protects maize leaves

The cuticle is a waxy covering of a leaf that helps prevent water-loss. A new study of adult maize leaves shows it's not a simple structure.

Trees fight infections by building barricades, but how?

Trees fight infections by trapping pathogens in one part of the tree. Hugh Morris and colleagues have been reviewing how trees use secondary metabolites in order to control the process.

X-ray CT scanning can boost tree-ring research

A new technique to scan tree rings offers to yield precious new data on past climates.

How do marshes migrate?

New research shows that marsh plants may be lying in wait in marshes-to-be, waiting for geological processes to catch up.

Even a small change in topography can help tides drive an oxygen pump

For pioneer species in the marshes, it's a case of grow fast or die young. But the differences in growth speed can be caused by tiny changes in geography.

A plant thought to aid Nothofagus may be out-competing it

The idea was simple, Proteaceae plants are experts at releasing phosphorus from soils, so planting them alongside Nothofagus should provide the beeches with natural fertilizer. The reality is more complex.

How kelp protects coasts

Some protection from waves crashing on the shore could be found in what lies beneath the surface.

Why do some columbines make life harder for their pollinators?

The flowers of Aquilegia eximia, the serpentine columbine, face downward, but the hummingbirds that pollinate it prefer horizontal flowers, so why do the flowers face the wrong way?

How arbuscular mycorrhizal fungi talk to plants before colonisation
