Vertical farms with their soil-free, computer-controlled environments may sound like sci-fi, but there is a growing environmental and economic case for them, according to new research laying out radical ways of putting food on our plates.
Microplastics, tiny plastic particles less than 5 millimeters in length, can now be found throughout the ocean and other aquatic ecosystems, and even in our seafood and salt. As microplastics have become ubiquitous, scientists have become concerned about their transfer from the environment to the food chain and their potential impact on human health.
Grapevine is infected by more than 90 viruses, with new viral species discovered yearly as a result of the newer technology introduced by High-Throughput Sequencing (HTS). Within the last decade, HTS is used for virome identification (the assemblage of viral genomes), which in turn helps plant pathologists with future research.
Guam is home to “Cycas micronesica”, an arborescent cycad species that is facing threats from several invasive insect pests. The once widespread tree has been decimated from the forests on Guam and the nearby island of Rota, leading the International Union for Conservation of Nature to list the gymnosperm tree species as endangered.
Findings pave the way for developing environmentally friendly fungicides. Fungal diseases cause substantial losses of agricultural harvests each year. The fungus Botrytis cinerea causing gray mold disease is a major problem for farmers growing strawberries, grapes, raspberries, tomatoes and lettuce. To mitigate the problem, they often resort to applying chemical fungicides which can lose their effectiveness over time.
Crop hybrid technologies have contributed to the significant yield improvement worldwide in the past decades. However, designing and maintaining a hybrid production line has always been complex and laborious. Now, researchers have developed a new system combining CRISPR-mediated genome editing with other approaches that could produce better seeds compared with conventional hybrid methods and shorten the production timeline by 5 to 10 years.
New research shows, in a world first, a recreation of the evolution of flowering plants through time – a complete angiosperm ‘time-tree’.
A new study has analyzed one environment-sensitive genic male sterile (EGMS) line that exhibited fertility transition under specified environmental conditions.
After several years of experimentation, scientists have engineered thale cress, or Arabidopsis thaliana, to behave like a succulent, improving water-use efficiency, salinity tolerance and reducing the effects of drought. The tissue succulence engineering method devised for this small flowering plant can be used in other plants to improve drought and salinity tolerance with the goal of moving this approach into food and bioenergy crops.
Many small regulatory elements, including miRNAs, miRNA binding sites, and cis-acting elements, comprise only 5~24 nucleotides and play important roles in regulating gene expression, transcription and translation, and protein structure, and thus are promising targets for gene function studies and crop improvement.
