It is our great honor to welcome you to the 3rdBeijing International Symposium on Molecular Plant Pathology (3rd BISMPP), hosted jointly by the China Society of Plant Protection (CSPP), the State Key Laboratory for Biology of Plant Diseases and Insect Pests (SKLBPI) and the Beijing Society for Plant Pathology (BSPP). I hope you are as excited as we are to be in Beijing, China’s beautiful and historic capital city for our gathering to exchange research results and ideas. As a continuing effort after the previous two BISMPPs held in Beijing in 2011 and 2013, this meeting will continue cover a wide range of scientific topics regarding molecular plant pathology and plant disease control, and help our colleagues build new international collaborations. We are confident that you will enjoy the discussions with scientists around the world to discuss new developments and future directions.
