Abstract: | Gomortega keule (Molina) Baillon is an endangered, rare species, the only representative of its genus, and endemic to Central Chile. Populations
of this tree are now fragmented and few individuals can be found in any of them. Genetic diversity was studied in 33 individuals
from three populations in Cauquenes, a coastal mountain area (35°58'S-72°41'W). Fifteen InterSimple Sequence Repeat primers
were used to determine the degree of similarity between and within populations. This revealed that 30% of the variation exhibited
was between populations while 70% was within; nevertheless individuals were clearly clustered in a pattern which reflected
a narrow base of diversity. Three other species from the Laurales order were used in order to provide an external reference
as to the degree of diversity. In addition, an external wild population from the native species, Peumus boldus, was used to verify the utility of the markers. We show that the primers are effective in quickly giving an estimate of the
degree of diversity of a population, thus giving important topical information relevant to preserving endangered species.
Aspects of the conservation and management policy for the species in order to maintain the remaining populations and to preserve
the genetic resources are discussed. |
