CSU biologists have traced the stability of plant mitochondrial genomes to a particular gene - MSH1 - that plants have but animals don't. Their experiments, described in Proceedings of the National Academy of Sciences, could lend insight into why animal mitochondrial genomes tend to mutate.
The discovery unveils the molecular machinery that plants use to weave cellulose chains into cable-like structures called 'microfibrils.'
Positive news for 'ohi'a restoration in Hawai'i! A new USGS study indicates that 'ohi'a seedlings planted into sites with active Rapid 'Ohi'a Death (ROD) infections can survive for at least one year. ROD is a newly emerging disease that has killed at least 1 million 'ohi'a - a tree that is foundational to the Hawaiian landscape and culture. Its loss is detrimental to endangered birds and plants, ecosystem processes, and the cultural heritage of Hawaiians.
Genetically speaking, the loaf of bread you stress-baked during the COVID-19 shutdown is more complex than you think. Wheat's 16 billion genes, organized in not one but three semi-independent genomes, can overlap or substitute for one another, making things extremely tricky for geneticists trying to enhance desirable traits in the world's most widely grown crop.
With increasing drought conditions in the Texas High Plains, researchers test sorghum and pearl millet as alternatives to corn.
The need to cover an open wound on cycad stem cuttings has been confirmed by the Western Pacific Tropical Research Center at the University of Guam in a study published in the Tropical Conservation Science journal on April 27. And the scientists have shown that the list of products that effectively fulfill this purpose is not restrictive.
The protein could help develop drought-resistant plant varieties and products that reduce losses related to climate change.
Researchers from the School of Biological Sciences and Swire Institute of Marine Science at the University of Hong Kong are working to understand how the coral symbiosis may respond to global warming through changes in their microbiome, specifically their symbiotic algae. Using a newly developed method they revealed , which may be a determining factor in the sucthe metabolic function of algae changes in response to competition with other speciescess or failure of certain host-symbiont combinations.
A method to extract carbohydrates and phycobiliproteins from algae was developed that does not kill the algae during harvest or rely on solvents for extraction and purification. This novel method uses mechanical shearing to 'milk' the desired compounds, greatly reducing the production cost of algae-derived compounds.
Large blocks of 'plug and play' genes play a super-sized role in adaption-and may help fill lingering gaps in Darwin's theories
