Historically credited as being the first bacterium ever characterized as a plant pathogen, fire blight is a bacterial disease that leads to significant losses of pear and apple. The role of insects in the spread of this disease has been long studied. In a new study, plant pathologists based at Cornell University and Cornell AgriTech take a hypothesis that has been more or less ignored for 100 years and provided support for its validity.
A seven-year analysis of almost 10,000 Harmful Algal Blooms (HAB) events worldwide over three decades will be published by the HAB Programme of UNESCO's Intergovernmental Oceanographic Commission. More than 100 scientists in 112 countries contributed to the synthesis and analysis of HAB data gathered from 1985 to 2018 -- a first-ever big data approach to detecting changes in the costly phenomenon's global distribution, frequency, and intensity.
Scientists of Tomsk Polytechnic University, in cooperation with the Czech colleagues have developed a new hydrogel for agriculture. It is meant to retain moisture and fertilizers in soil. The difference of the new hydrogel from other formulations is that it is made entirely of natural components and degrades in soil into nontoxic products to humans, animals, and plants. The research results are published in the Journal of Cleaner Production (IF: 7, 246; Q1).
Scientists have conducted a 'molecular dissection' of a part of the virus that causes foot-and-mouth disease, to try and understand why the pathogen is so infectious. A team of scientists from the University of Leeds, UK, and University of Ilorin, in Nigeria, has investigated the significance of the unusual way the virus's genome - or genetic blueprint - codes for the manufacture of a protein called 3B. The protein is involved in the replication of the virus.
A team from the Diverfarming project has found microplastics in 92% of the faeces of sheep fed in intensive agricultural zones of Murcia that they analysed
Bread wheat can grow in highly diverse regional environments. An important reason for its great genetic variety is the cross-hybridization with many chromosome fragments from wild grasses. This is shown by the genome sequences of 10 wheat varieties from four continents, which an international consortium including researchers from the University of Zurich has now decoded.
A research team led by the University of Washington and Pacific Northwest National Laboratory has shown that microbes taken from trees growing beside pristine mountain-fed streams in Western Washington could make phosphorus trapped in soils more accessible to agricultural crops.
A common insecticide that is a major hazard for honeybees is now effectively detected in honey thanks to a simple new method.
A 'game changing' study deciphering the genetic material of the desert locust by researchers at the University of Leicester, could help combat the crop-ravaging behaviour of the notorious insect pest which currently exacerbates a hunger crisis across many developing countries.
UC San Diego researchers have identified the first key biological switch that sounds an alarm in plants when plant-eating animals attack. The mechanism will help unlock a trove of new strategies for improved plant health, from countering crop pest damage to engineering more robust global food webs.
