Bioengineering photoreception regulation improves soybeans photosynthesis and crop yields [Full subscriber]
RIPE researchers have shown that bioengineering soybean plants to improve regulation of photoprotection – a natural process that enables plants to cope with damaging excess absorbed light energy in full sunlight – improved soybean seed yield by up to 33% in field trials.
Bioengineers identify the key genes and functions for sustaining microbial life [Registered]
According to the researchers, these findings could open up new avenues for cell engineering applications. Consider, for example, the genetic engineering of microbes to make value-added chemicals. This engineering process is typically done by making changes to the genetic makeup of a cell, which can end up toying with the cell’s core genes and functions, resulting in a “sick” cell.
Bioengineered bacteria helps produce isopropanol from solar energy [Registered]
They have created a system that uses bacteria (Ralstonia eutropha) to convert solar energy into a liquid fuel. Their work integrates an “artificial leaf,” which uses a catalyst to make sunlight split water into hydrogen and oxygen, with a bacterium engineered to convert carbon dioxide plus hydrogen into the liquid fuel isopropanol.
