Lutz‐Carrillo, Dijar J., Gregory M. Southard, and Loraine T. Fries, 2010. Global Genetic Relationships Among Isolates of Golden Alga ( Prymnesium parvum ). Journal of the American Water Resources Association (JAWRA) 46(1):24‐32. DOI: 10.1111/j.1752‐1688.2009.00388.x Abstract: Prymnesium parvum is considered among the most harmful algal species in the world for finfish and other gill breathing organisms. Although it is globally distributed, with the exception of Antarctica, P. parvum is usually associated with coastal and brackish waters. Historically, P. parvum incidents were recorded in the eastern hemisphere; however, in 1985 it was detected in inland Texas waters. We used DNA sequence variation of the first internal transcribed spacer in the nuclear ribosomal operon (ITS1) among multiple samples of P. parvum from Texas and other locales to address the possible origins of P. parvum in Texas and the United States (U.S.). With the exception of a sample from Diversion Lake, other samples from Texas, South Carolina, and Wyoming exhibited limited genetic variation and were similar in sequence to a sample from Scotland. The Diversion Lake sample was similar in sequence to samples from Denmark and Norway, and the Maine sample was highly similar to samples from England. These results suggest multiple independent introductions of P. parvum to the U.S.
