THE SCIENTIFIC RESEARCH PROGRAM


    What are the genetics of Astrophytum and Lophophora?
            The Institute's president, Dr. Martin Terry (who holds the required DEA and Texas Department of Public Safety registrations to conduct research on peyote) worked with Drs. James Manhart and Alan Pepper on population genetics projects involving star cactus and peyote for 2-½ months during the summer of 2005 at Texas A&M University.
            The star cactus population genetics work is part of a multi-species project on endangered plants in South Texas that has been funded at Texas A&M by the U.S. Fish and Wildlife Service (USFWS) and the U.S. Geological Survey (USGS).
            Dr. Terry is one of the investigators on the grant.

          The peyote research was started previously by Terry at Texas A&M and, during the summer of 2006, some significant progress was made on the technical details of characterizing the genetic diversity of different peyote populations.

        An exciting field study occurred in 2007 that enabled the successful collection and purification of DNA samples from a number of the known Lophophora species in Mexico. Samplings were obtained from more than one population each of L. diffusa, L. fricii, L. koehresii & L. williamsii.
            How these samples are collected in the field.
            The results of the ongoing analysis is hoped to contribute to our actual understanding of how these plants are related to each other.
