In Sept. 21, Dr. Francisco Vilaplana from KTH KTH Biotechnology/Glycoscience Division and Wallenberg Wood Science Centre (WWSC) visited our center. Dr. Vilaplana has a long-term study on the characterization of complex cell wall and energy-reserve polysaccharides by the use of advanced chromatographic and mass spectrometric techniques coupled with biochemical approaches. His research mainly focused on the intramolecular substitution pattern and the macromolecular architecture. SCCB has established bilateral collaboration with him on starch structure of root crops and the joint experiment data were discussed during his visit. Accompanied by center members, Dr. Vilaplana also visited the center and greenhouse. His visit promotes the bilateral cooperation in the future. Prof. Peng Zhang, Dr. Jun Yang and Dr. Wenzhi Zhou attended the discussion.
