Scientists studying how tiny algae renew old or damaged cell proteins say their findings could be useful in developing crops suited to climates in which weather changes quickly.
Researchers found that the speed at which protein renewal takes place dictates how quickly they can adapt to environmental changes, such as a sudden frost or drought.
The team found that renewal rates vary between proteins according to their role and their location within cells. Proteins that carry out photosynthesis – the process that converts sunlight into energy – renew quickly because they are at risk of light damage. Conversely, proteins that protect DNA in plant cells are at little risk of damage, and renew slowly.
The findings, by researchers at the University of Edinburgh, could help breed crops incorporating proteins that respond quickly to changing conditions. Conversely, it could also assist development of high-yield crops in stable environments, where little adaptation to conditions is required.
Scientists made their discovery by developing a method to detect how quickly algae take up nitrogen – which is used to produce proteins – from their food. The study was funded by the Biotechnology and Biological Sciences Research Council and the Engineering and Physical Sciences Research Council, and published in the Journal of Proteome Research.
Dr Sarah Martin of the University of Edinburgh's Centre for Systems Biology, who led the study, said: "Until now, we knew that plants replaced their old and damaged proteins, but we had no idea how long this process took for individual proteins, or how this varied between different parts of the plant. Our findings will be useful in understanding more about how plants are programmed for survival."

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
