New findings show that a micro RNA from the shoot keeps legume roots susceptible to symbiotic infection by downregulating a gene that would otherwise hinder root responses to symbiotic bacteria. These findings help us understand what it takes to make nitrogen-fixing symbiosis efficient, and what we need to do to exploit it agronomically.

"Health trumps politics,” said Iowa State Senator David Johnson before taking the stage at a raucous rally in Des Moines last winter to support strengthening the state’s water quality. In the marble rotunda of the state capitol, he rose to denounce the nitrogen and phosphates that have been flowing in ever-increasing quantities into Iowa’s public water supplies — and was cheered by the small crowd of family farmers, concerned mothers, and his new political allies, the legislature’s drastically outnumbered Democrats. Johnson had been one of the longest-serving Republicans in Iowa until he left the party to become an independent in 2016 after defying it  repeatedly on one of the most divisive issues in Iowa — the integrity of the state’s water.

Scientists have determined for the first time that Amazon’s waterlogged coastal mangrove forests, which are being clear cut for cattle pastures and shrimp ponds, store significantly more carbon per acre than the region’s famous rainforest.

Current climate change models might be overestimating how much carbon dioxide plants can suck from the atmosphere.

Researchers have perked up at the opportunity to brew some coffee-growing solutions.

The natural world has had billions of years of evolution to perfect systems, creating elegant solutions to tricky problems.

A growing world population means that more food is needed which in turn may require more land to grow food crops. More agriculture, however, results in increased irrigation, particularly for food crops such as maize and wheat – especially in dry regions. Combined with the use of fertilizer, this leads to salt accumulation in soils. To be able to use saline soils, naturally salt-tolerant plants, the so-called halophytes, are of great interest. The pseudo-cereal quinoa (Chenopodium quinoa) is one of them. Quinoa originated in the Andean region and is adapted to harsh environmental conditions. In the South American mountain range, the cereal-like plant has been used as a food crop for 7000 years. Gluten-free and high in vitamins, the edible seeds have now found their way into European supermarkets.

Connecting Environmental Sustainability with the Science oBrock University biology professors are among a group of researchers participating in a Canada-wide research cluster aimed at boosting the nation’s organic farming sector.

Insect pollinators that have survived the impacts of agricultural intensification may have a greater ability to resist future environmental changes than previously thought, a new study has found.

Scientists have discovered that moths may play a much broader role as plant pollinators than previously suspected.
