Alfalfa (Medicago sativa) is a legume grown in many parts of the world as a source of animal fodder. It is prized in the forage industry for its high protein content and biomass yield. Recently, alfalfa protein has found applications in aquaculture, pet food industry and human diet. Furthermore, it is seen as an environmentally beneficial crop, with positive impacts on biodiversity and soil nitrogen conservation.
Scientists have warned of the ‘devastating’ impact that fungal disease in crops will have on global food supply unless agencies across the world come together to find new ways to combat infection. Worldwide, growers lose between 10 and 23 per cent of their crops to fungal infection each year, despite widespread use of antifungals. An additional 10-20 per cent is lost post harvest. Academics predict those figures will worsen as global warming means fungal infections are steadily moving polewards, meaning more countries are likely to see a higher prevalence of fungal infections damaging harvests.
According to a new study ditches in forestry-drained peatlands release less methane into the atmosphere than what has previously been estimated.
New research has identified a new protein complex in plants that regulates temperature response by the circadian clock. As climate change influences daily and seasonal temperature patterns – such as warmer nights and winters – it is critical to better understand how plants interpret and react to thermal cues.
An international team of researchers has fully sequenced the genome of a climate resilient bean that could bolster food security in drought-prone regions.
Plant trichomes are highly specialized structures that develop from the epidermal pavement cells of different plant tissues. They are known to defend plants from biotic and abiotic stresses such as water loss, insect-inflicted damage, pathogen attacks, deadly ultraviolet radiation, and leaf temperature reduction. A research team from China recently utilized computer vision, artificial intelligence, and deep learning techniques to develop an automatic algorithm to count and measure maize trichomes.
Over the past few decades, it has become obvious that climate change, and consequent extreme weather events, can wreak havoc on crop yields. Concerningly, there is a large disparity in agricultural vulnerability between developed and developing countries. In a new study, researchers have looked at major food grains in India to understand the long- and short-term effects of climate change on crop yields.
Researchers have reconstructed the evolutionary history of a highly specific olfactory receptor in the Egyptian cotton leafworm, a crop pest. This receptor plays an essential role in moth reproduction because it allows males to recognise the female sex pheromone. The scientists determined that the receptor appeared around 7 million years ago and that eight amino acids underlie receptor-pheromone binding. Their findings can guide the development of biocontrol strategies directed against this pest.
Botanists and paleontologists have identified a fossil chili pepper that may rewrite the geography and evolutionary timeline of the tomato plant family.
Anthropogenic climate change has, together with the intensive use and destruction of natural ecosystems through agriculture, fishing and industry, sparked an unprecedented loss of biodiversity that continues to worsen. In this regard, the climate crisis and biodiversity crisis are often viewed as two separate catastrophes. An international team of researchers calls for adopting a new perspective. In their review study they recommend (in addition to complying with the 1.5-degree target) protecting and restoring at least 30 percent of all land, freshwater and marine zones, establishing a network of interconnected protected areas, and promoting interdisciplinary collaboration between political institutions, which often operate independently.
