A team involving Kobe University researchers has succeeded in developing Target-AID, a genome editing technique that does not cleave the DNA. The technique offers a method to address the existing issues of genome editing. It is expected that the technique will be applied to gene therapy in the future in addition to providing a powerful tool for breeding useful organisms and conducting disease and drug-discovery research.
Field studies in two Florida locations evaluated and compared anaerobic soil disinfestations (ASD) and chemical soil fumigation (CSF) performance on weed and nematodes control, and on fruit yield and quality of fresh-market tomato. Results indicated that ASD (applied using a mixture of composted poultry litter and molasses as carbon source) may be a potentially sustainable alternative to conventional CSF for controlling plant-parasitic nematodes and weeds without causing negative effects on fruit yield and quality.
A study evaluated the influence of nitrogen fertility levels on biomass and concentrations of nutritionally important carotenoid and chlorophyll pigments in purslane. Two purslane cultivars were grown in nutrient solution culture under four nitrogen concentrations. Results showed no influence of nitrogen treatment concentration on purslane shoot tissue fresh weight accumulation. Nitrogen treatment significantly influenced purslane shoot tissue beta-carotene, lutein, neoxanthin, total carotenoids, chlorophyll a, chlorophyll b, total chlorophyll, and the chlorophyll a to b ratio.
A new study from University of Michigan researchers challenges the widely held assumption that biofuels such as ethanol and biodiesel are inherently carbon neutral.
Plants are adapting to increasing atmospheric CO2 according to a new study from the University of Southampton. The research, published in the journal Global Change Biology, provides insight into the long-term impacts of rising CO2 and the implications for global food security and nature conservation.
Humans utilize forests and watercourses in a way that depletes ecosystem habitats, biodiversity and ecosystem services. Many areas are restored to break the trend, but to succeed you need to consider not only the ecosystem in mind, but also surrounding ecosystems. This according to researchers in Umeå in Sweden in an article published in BioScience.
Nature abounds with examples of mutualistic relationships. Think of bees pollinating flowers whose nectar nourishes the bees. Each species benefits the other, and together their chances of survival are better than if they lived apart. Now scientists at MIT have found that such mutualistic relationships aren't always set in stone. Depending on environmental conditions, once-simpatico species can become competitors, and in extreme cases, one species can even drive the other to complete extinction.
Scientists from the University of New Hampshire have unlocked a major genetic mystery of one of the ancestors of cultivated strawberry. A genetic analysis conducted by New Hampshire Agricultural Experiment Station researchers, which took four years to complete, aims to improve modern cultivation efforts of strawberry growers.
It's a familiar hazard of vacation time: While you're conspicuously absent, your colleagues in the office forget to water and fertilize the plants -- often leaving behind nothing but a brownish skeleton. Whether a plant thrives or wastes away depends above all on whether its roots get enough water and nutrients. Geophysicists at the University of Bonn have now visualized such processes for the first time using electrical impedance tomography.
Analytical approach could accelerate the development of new preservation treatments delivering environmental benefits and help in the design of bio-inspired smart actuators.
