Widespread fungal disease in plants can be controlled with a commercially available chemical that has been primarily used in medicine until now. This discovery was made by scientists from Martin Luther University Halle-Wittenberg (MLU) and the University of the State of Paraná in Brazil. In a comprehensive experiment the team has uncovered a new metabolic pathway that can be disrupted with this chemical, thus preventing many known plant fungi from invading the host plant.
A new study finds that glyphosate residue from herbicides in manure fertilizer decrease the growth of strawberry and meadow fescue as well as runner production of strawberry.
Stripe rust is one of the most destructive wheat diseases in the world, especially in the United States. While the disease can be controlled by chemicals, those may be harmful to humans, animals, and the environment and the application can cost millions of dollars. Rather than use chemicals, many farmers would prefer to grow wheat varieties that resist stripe rust and the development of such varieties is a top priority for wheat breeding programs.
The collaboration revealed that the symbiotic relationship between plants and fungi provides nitrates to plants, which could lead to reduced fertilizer use.
The amount of synthetic microfiber we shed into our waterways has been of great concern over the last few years, and for good reason: Every laundry cycle releases in its wastewater tens of thousands of tiny, near-invisible plastic fibers whose persistence and accumulation can affect aquatic habitats and food systems, and ultimately our own bodies in ways we have yet to discover.
Researchers at the Western Pacific Tropical Research Center at the University of Guam have documented what biologists call a "host shift" of the coconut rhinoceros beetle in Guam. The beetle, first documented as an invasive species in Guam in 2007, has been devastating the island's ubiquitous coconut trees and is now also burrowing into Guam's endangered native cycad tree, Cycas micronesica.
Synthetic auxin products have given growers an important option for managing weed populations resistant to glyphosate and other herbicides. But according to an article featured in the journal Weed Technology, there is one important downside to dicamba, 2,4-D and other synthetic auxins. They often move off-target and can cause severe injury to sensitive plants growing nearby.
Despite the importance of changes in root architecture to exploit local nutrient patches, mechanisms integrating external nutrient signals into the root developmental program remain poorly understood. "Here, we show for the first time that local ammonium supply stimulates the accumulation of auxin in the root vasculature and promotes auxin diffusion and lateral root formation to build a highly branched root system", says Prof. Nicolaus von Wirén from the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK).
CABI scientists have led the first assessment of naturalised, invasive and potentially invasive plant species present in Laikipia County, Kenya, which hosts the highest populations of endangered large mammals in the country. The research led by Dr Arne Witt suggests that a range of invasive alien plants pose a series risk to the County - home to the second-highest number of endangered wildlife in East Africa including elephant, rhino, Grevy's zebra, reticulated giraffe and wild dogs.
Phosphorus is essential for agriculture, yet this important plant nutrient is increasingly being lost from soils around the world. The primary cause is soil erosion, reports an international research team led by the University of Basel. The study in the journal Nature Communications shows which continents and regions are most strongly affected.
