Newly discovered 'scarecrow' gene might trigger big boost in food production
With projections of 9.5 billion people by 2050, humanity faces the challenge of feeding modern diets to additional mouths while using the same amounts of water, fertilizer and arable land as today.

How salt stops plant growth
Until now it has not been clear how salt, a scourge to agriculture, halts the growth of the plant-root system. A team of researchers, led by the Carnegie Institution's José Dinneny and Lina Duan, found that not all types of roots are equally inhibited. They discovered that an inner layer of tissue in the branching roots that anchor the plant is sensitive to salt and activates a s

Plants adapt to drought but limits are looming, study finds
Scientists with the U.S. Department of Agriculture, or USDA, and their partners have determined that water demand by many plant communities can fluctuate in response to water availability, indicating a capacity for resilience even when changing climate patterns produce periodic droughts or floods. But their research also suggests that a limit to this resilience ultimately could threaten the su

Photosynthesis: The last link in the chain
For almost 30 years, researchers have sought to identify a particular enzyme that is involved in regulating electron transport during photosynthesis. A team at Ludwig-Maximilians-Universität (LMU) in Munich has now found the missing link, which turns out to be an old acquaintance.

Boosting galactan sugars could boost biofuel production
Galactan is a polymer of galactose, a six-carbon sugar that can be readily fermented by yeast into ethanol and is a target of interest for researchers in advanced biofuels produced from cellulosic biomass. Now an international collaboration led by scientists at the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI) has identified the first enzyme capable of substantially boosting t

To outsmart malarial drug resistance, research team develops new whole-plant strategy
Malaria brings misery and death to millions in the developing world each year, and fighting it keeps medical researchers up at night because the mosquito-borne parasite Plasmodium falciparum, which causes the deadliest form of the disease, has developed resistance to every drug thrown at it. Resistance has cut short the useful life of nearly every therapy tried so far, expe

Do palm trees hold the key to immortality?
For centuries, humans have been exploring, researching, and, in some cases, discovering how to stave off life-threatening diseases, increase life spans, and obtain immortality. Biologists, doctors, spiritual gurus, and even explorers have pursued these quests—one of the most well-known examples being the legendary search by Ponce de León for the "Fountain of Youth."

Tracking gene flow in marine plant evolution
A new method that could give a deeper insight into evolutional biology by tracing directionality in gene migration has just appeared in EPJ Data Science.

Long-distance solute transport in trees improved by intercellular pathways in living woody tissues
As large organisms, trees face some remarkable challenges, particularly regarding long-distance transport and communication. In addition to moving water and nutrients from their roots to their leaves, they must also integrate cell-to-cell communication over large areas. Furthermore, in order to function as a single, cohesive organism they must be able to effectively and efficiently send vital sub

What happens to plant growth when you remove gravity?
It is well known that plant growth patterns are influenced by a variety of stimuli, gravity being one amongst many. On Earth plant roots exhibit characteristic behaviours called 'waving' and 'skewing', which were thought to be gravity-dependent events. However, Arabidopsis plants grown on the International Space Station (ISS) have proved this theory wrong, according to a study published in

Tiny algae shed light on photosynthesis as a dynamic property
One of the first chemical reactions children learn is the recipe for photosynthesis, combining carbon dioxide, water and solar energy to produce organic compounds.

The hungry caterpillar: Beware your enemy's enemy's enemy
When herbivores such as caterpillars feed, plants may "call for help" by emitting volatiles, which can indirectly help defend the plants. The volatiles recruit parasitoids that infect, consume and kill the herbivores, to the benefit of the plant. However, such induced plant odours can also be detected by other organisms.

Scientists discover new way in which plants control flower production
Flowers don't just catch our eyes, they catch those of pollinators like bees as well. They have to, in order to reproduce. Because plants need to maximize the opportunity for pollinators to gain access to their seeds, variations in the timing of flowering can have profound effects on flower, fruit, and seed production, and consequently agricultural yields.
