On November 30, 2020 an online scientific seminar was held at the Institute of Molecular Biology and Biotechnologies. A junior researcher of the Proteomics laboratory Aynura Pashayeva gave a report on the topic "Dynamic organization of photosynthetic complexes in plant thylakoid membrane". The recent developments in unravelling the role of the LHCII and PSII core protein phosphorylation in the dynamic function of plant thylakoid membrane upon changing environmental cues, particularly the light intensity were emphasized. Within the framework of the seminar, the main aspects of the topic were announced, the most problematic issues and ways to resolve them were discussed.
