Researchers discover that chloroplasts control ripening in crops [Registered]

Biologists may have unearthed the potential to control ripening in crops by manipulating the functions of chloroplasts, the parts of plant cells responsible for photosynthesis. Researchers in the University of Leicester’s Department of Biology discovered that chloroplasts are affected by the ubiquitin proteasome system (UPS) – a process which causes the breakdown of unwanted proteins in cells, previously thought to only act on central parts of the cell. As a result, the researchers believe they may be able to use specific proteins to regulate the functions of chloroplasts – such as the conversion of chloroplasts into highly-pigmented chromoplasts during the…
