Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. An international team of plant biologists has demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein. A better understanding of the processes that regulate root branching at the molecular level could contribute to improving plant growth and therefore crop yields.
In a comprehensive review of breeding salinity tolerance in plants, researchers argue that the main reason research advances have not been translated into commercial salt-tolerant crop varieties for farmers is that this has not been a priority for plant breeders. However, with increasing impacts of climate change due to sea-level rise and storm surges forcing seawater further inland, the need to increase crop salinity tolerance is becoming more urgent, and so priorities will change.
Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information that are responsible for this variation. A research team has now developed a method to identify precisely these special differences in genetic information. Using the example of maize, they demonstrate the great potential of their method and present regions in the maize genome that may help to increase yields and resistance to pests during breeding.
Researchers have discovered the secrets behind how plants move sugar using a protein called the SUC transporter. This breakthrough solves a long-standing mystery of the plant ‘heart’ and sheds new light on how plants defend themselves from pests.
Tomatoes, bananas, cabbages, melons, pumpkins and cucumbers… are just some of the 150 crops of commercial interest that are victims of Fusarium oxysporum, one of the most important pathogens in the world due to the millions of dollars in losses it is responsible for and its ability to attack different types of plants. Although it can go unnoticed in the soil for more than 30 years, when it detects the roots of a host plant, it grows towards them, colonizing its vascular system and causing crops to wilt.
New research has tracked Japanese hanami (flower viewing) via social media images, producing an unprecedented map of cherry blossoms across Japan to document their annual bloom and calculate its peak in major cities.
A new study analyzed DNA from ancient local winegrape seeds discovered at archaeological excavations in the Negev.
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.
