IGLESIAS ANDREU, L. G. y TIVO FERNANDEZ, Y.. Protein polymorphism in Pinus hartwegii Lindl. at Cofre de Perote, Veracruz, Mexico. Rev. Chapingo ser. cienc. for. ambient [online]. 2008, vol.14, n.1, pp.5-9. ISSN 2007-4018.
We evaluate the globulins and total proteins composition in megagametophytes tissue from seeds collected in a natural population of Pinus hartwegii located at Cofre de Perote, Veracruz. Electrophoresis was performed in a discontinuous system of polyacrylamide gels (PAGE). Results shown a good resolution and repeatability in obtained protein profile. It was detected the presence of four haplotypes. The trees under study were classified in three groups. The group I that contained the majority of evaluated trees (70 %), was characterized for the presence of haplotype I. Our results suggest the presence of certain inbreeding degree in this population.
