Protein root discovery seals future of climate-proof plants

Researchers have discovered a protein that seals plant roots to regulate the uptake of nutrients and water from the soil, the discovery could help develop climate proof crops that require less water and chemical fertilizers.

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 ...

Biology trumps chemistry in open ocean

Single-cell phytoplankton in the ocean are responsible for roughly half of global oxygen production, despite vast tracts of the open ocean that are devoid of life-sustaining nutrients. While phytoplankton's ability to adjust ...

Genes controlling mycorrhizal colonization discovered in soybean

Like most plants, soybeans pair up with soil fungi in a symbiotic mycorrhizal relationship. In exchange for a bit of sugar, the fungus acts as an extension of the root system to pull in more phosphorus, nitrogen, micronutrients, ...

Exploring the genetic basis of the root economics spectrum

By analyzing the acquisition-conservation tradeoff in root systems among different plants, ecologists have put forward the root economics spectrum (RES) hypothesis. Some plant species have finer and cost-effective absorptive ...

Length of pregnancy influenced by placenta structure

The nine-month pregnancy in humans is influenced by the structure of the placenta, according to new research into the evolution of reproduction in mammals which ends a 100-year mystery.

Better anchor roots help crops grow in poor soils

A metabolite in plants that regulates the growth of anchor roots—vital for sustaining water and nutrient uptake in plants—has been identified and may have useful applications in agriculture.

Fungi adapted to mines boost plant growth

(PhysOrg.com) -- Repopulating the moon-like terrain around abandoned mines is slow, plodding work, but a new Indiana University Bloomington report in Applied Soil Ecology suggests symbiotic fungi specifically adapted to toxic ...

Clues to bee health found in their gut microbiome

The local environment plays a pivotal role in the health and diversity of the gut microbiome of wild bees which could help detect invisible stressors and early indicators of potential threats, say York University scientists ...
