The Swedish university has placed the blame on a guest researcher from China who reported results that the research group was unable to recreate later. Tao Huang, the researcher in question, denies any wrong doing and claims the results are valid. From the article, Ove Nilsson who is the research professor from the Faculty of Science and Agriculture at Umeaa University told AFP, "Chinese researchers are under a lot of pressure from their country and are expected to produce a maximum amount of results in order to get a job." The research initially claimed to have proven that the florigen molecule that controls plant blooming plays the role of messenger in the process."
