Light drives photosynthesis, but excessive light can be harmful. Plants protect themselves by converting surplus energy in their chloroplasts into heat for dissipation. PhD student Sanchali Nanda helped validate a novel instrument that monitors the stress levels of plants and used it to gain new insights on their energy dissipation mechanisms.

PhD student Varvara Dikaya has studied how plants adjust to cold by focussing on the protein PORCUPINE (photo: Nabila El Arbi).
Plants have developed versatile processes to react to cold temperatures. Varvara Dikaya studied PORCUPINE, a protein that is part of a hub regulating responses to environmental cues like cold. In her PhD thesis, she showed that there is not just a single link between PORCUPINE and cold signalling, but multiple intertwined passes that act simultaneously.

Scientists at Umeå University have found a way to break open the protective walls of pollen grains – one of the hardest biomaterials in the world – without damaging the inside cell and its components. This achievement opened the possibility to isolate and study mitochondria – parts of the cell essential for energy production. To their surprise, several proteins that are key for maintaining the energy production of the mitochondria, were nowhere to be found.

Today is the 10th International Day for Women and Girls in Science. The goal is to highlight the need to advance gender equality and celebrate diversity in science. UPSC has been striving for gender balance already since 2007 and has currently achieved it, but the work to create a more diverse, inclusive and equitable environment continues.

PhD student Nabila El Arbi (right) successfully defended her PhD thesis that was supervised by Markus Schmid (left). The central dogma of biology states that DNA is transcribed into RNA, which is then translated into proteins, assuming that one gene contains the information for one protein. However, RNA modifications like alternative splicing can produce multiple proteins from a single gene. Not much is known about this in plants, but PhD student Nabila El Arbi dived into the unknown and started to enlighten it.
