Walls, toxicity and explosions: How plant cells protect themselves from salinity in soil
163278 web
(Carnegie Institution for Science) Roots face many challenges in the soil in order to supply the plant with the necessary water and nutrients. New work shows that one of these challenges, salinity, can cause root cells to explode if the risk is not properly sensed. Salinity has deleterious effects on plant health and limits crop yields, because salt inhibits water uptake and can be toxic for plants. But plant biologists discovered a never-before-described effect that salt has on the pl... www.eurekalert.org/pub_rele...

Study sheds light on how plants get their nitrogen fix
163223 web
(University of Tsukuba) Legumes are widely-consumed plants that use soil bacteria to obtain nitrogen through root nodulation. The process is energetically costly, and so legumes inhibit nodulation when soil nitrate is available. However, the mechanism that drives this inhibition is unknown. Researchers at the University of Tsukuba found that NRSYM1 is responsible for inhibiting nodulation in the presence of nitrate, and acts by directly regulating gene expression. The findings may aid ... www.eurekalert.org/pub_rele...

Bayer needs to ensure that a merger with rival Monsanto does not stifle competition in digital farming, the European Union's Competition Commissioner Margrethe Verstager told a German newspaper on Saturday. www.reuters.com/article/us-...

A genetic trigger adds branches to plants, could boost crop yields
162029 web
(American Chemical Society) When it comes to agriculture from branched plants, such as apple trees, the more branches that bear fruit, the better. But in the real world, there's a limit to the number of branches that plants make -- a gene tends to put the brakes on this splitting process called shoot branching. Today in ACS Central Science, researchers reveal a chemical that can reverse this limitation, possibly leading to improved crop production. www.eurekalert.org/pub_rele...

Weeds out of control
Herbicides can no longer control the weeds that threaten crop productivity and food security in the UK because the plants have evolved resistance, and future control must depend on management strategies that reduce reliance on chemicals. So concludes a nationwide epidemiological assessment of the factors that are driving the abundance and spread of the major agricultural weed, black-grass. www.sciencedaily.com/releas...

Efforts are needed to tap into the potential of nutraceuticals
A growing demand exists for nutraceuticals, which seem to reside in the grey area between pharmaceuticals and food. www.sciencedaily.com/releas...

Alien honeybees could cause plant extinction

(Anglia Ruskin University) New research indicates that introduced 'alien' honeybees are competing for resources with native bees and threatening the survival of plants that rely on interactions with specific pollinators. www.eurekalert.org/pub_rele...
