Experiments with the common morning glory reveal drought drives faster evolutionary changes in floral signals and rewards critical for plant-pollinator interactions compared to pollinator declines.

How Summer Heat Kills Fragile Flowers
New research reveals how heatwaves and drought together can rapidly and irreversibly damage flowers through a process called runaway cavitation.

How Wheat Outsmarts Drought
Scientists reveal how wheat's unique hydraulic system can cleverly reroute water supply to safeguard its reproduction during severe water shortages.
Drought damages a plant’s perfume
Bees may be using their sense of smell to detect and avoid stressed plants.
Poor acclimation to drought in subalpine forest tree seedlings
How do subalpine fir and Engelmann spruce seedlings respond to experimental drought when grown under field conditions?

Resilience of crops confirms that drought alone did not cause a ‘collapse’ in Mayan civilisation
In the 800s, Mayan cities in southeastern Mexico and Central America were abandoned - just as drought hit the region. But a botanical study shows that the connection between drought and depopulation was not simple.

Warm nights without respite accelerates the death of seedlings in a drought
A combination of morphological and physiological traits contribute to drought mortality, along with responses to night warming.
Plants drink in unknown ways on gypsum hills
Gypsum soils are dry and can be found in arid environments. Chemistry shows that a surprising variety of plants survive in them by getting water locked in crystals.
Drought response of European beech trees is not straight forward
Drought and rising temperatures can cause massive forest diebacks around the world. When a tree is experiencing drought, “shedding off” the leaves can enhance tree water status by reducing canopy transpiration. Whilst...

Pink monkeyflowers are a sign of local adaptation
Botanists find petal colour can signal a monkeyflower’s drought tolerance.
Global climate change and grasslands: soil microbial diversity to the rescue!
New study the journal New Phytologist reveals the importance of soil microbial diversity for tolerating or recovering from drought, warming and nitrogen deposition.
Quantifying root and shoot growth in wheat using X-ray Computed Tomography
How are relationships between root and shoot growth incluenced by drought and soil type in wheat?
Thicker roots: to grow or not to grow? Investigating the dynamics of secondary root growth
Secondary growth of the roots of annual dicots has functional significance with regards to soil resource acquisition and transport, interactions with soil organisms and carbon sequestration.
From computer to field: can in silico modelling can help us to optimise rice for possible droughts?
Advances in computational models may allow us to quickly predict responses of important food crops to environmental stresses in the field, and to identify the genetic basis of these.
