Researchers have identified a gene that could help engineer drought-resistant crops. The gene, called OSCA1, encodes a protein in the cell membrane of plants that senses changes in water availability and adjusts the plant's water conservation machinery accordingly.
An upcoming genetics investigation into the symbiotic association between soil fungi and feedstock plants for bioenergy production could lead to more efficient uptake of nutrients, which would help limit the need for expensive and polluting fertilizers.
By understanding the secret of how lizards regenerate their tails, researchers may be able to develop ways to stimulate the regeneration of limbs in humans. Now, a team of researchers is one step closer to solving that mystery.
In a new study, a thermosensitive collagen hydrogel remained as a liquid when kept at temperatures below 10C and gelled when the temperature was increased to 37C in an incubator for 30 minutes, which was used as an extracellular matrix and combined with bone marrow mesenchymal stem cells to construct tissue-engineered peripheral nerve composites in vitro.
In a boon to stem cell research and regenerative medicine, scientists have created a computer algorithm called CellNet as a 'roadmap' for cell and tissue engineering, to ensure that cells engineered in the lab have the same favorable properties as cells in our own bodies.
