• Biologists from the University of Leicester have found that chloroplast biogenesis is regulated by the ubiquitin proteasome system (UPS), a process that causes unwanted proteins in cells to break down.
  • Researchers theorize that they can use specific proteins to regulate chloroplast function, including “the conversion of chloroplasts into highly-pigmented chromoplasts during the ripening of fruit.” (details of how SP1 gene may be important in controlling fruit ripening available through link below)
  • Study that was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) can help improve crop yields and reduce food waste.
