Dear Colleagues,

We sincerely and warmly invite you to participate in the 6th Symposium on Plant Signaling & Behavior (PSB 2020), which will be held 27th-30th March 2020, in Haikou, a coastal city in Hainan Province of China. Haikou is the biggest city and capital of Hainan island, also named eastern Hawaii. Hainan is one of the free trade areas and the only international tourism island in China. International visitors from 59 countries can stay here VISA-FREE for 30 days. This symposium is held on behalf of the Society of Plant Signaling and Behavior, which was established in 2005 as the Society of Plant Neurobiology and changed its name in May 2009. The community is gathered by plant molecular biologists, physiologists and ecologists from different countries. The goal of this field is to illuminate the structure of the information network that exists within plants, among plant individuals and between plant and environments. This symposium is hosted by Hainan University, the only key university located in the tropical region of China. In December 2008, Hainan University was approved to be a state key university of “Project 211” and in 2018, the University was listed as a State “Double First-Class” Discipline Development University. The disciplines of animal and plant sciences were listed in ESI 1% in 2018. Hainan University will welcome all international scientists, academics and students for exchanging knowledge and stimulating innovation. This symposium will be held in the International Academic Exchange Center on the university campus, by a beautiful lake with mangroves and other tropical plants. Hainan province is called “Eastern Hawaii” since it is located at the same latitude. After the symposium, we will organize a post-symposium tour to Sanya city or a research visit to the biggest conservation zone for mangroves, Dong Zhai Gang Park. We are looking forward to meeting you in March, 2020, the most beautiful season in Hainan.
