Última Heterogeneous genetic structure in a natural population of Raulí (Nothofagus nervosa) Ciencia e Investigación Agraria Carrasco,Basilio; Eaton,Lafayette; Letelier,Luis; Díaz,Carole; García-Gonzáles,Rolando. Heterozygote deficiencies in natural populations of outbreeding tree species are common and thought to be due mainly to biparental inbreeding. Inbreeding is believed to be caused by family structure within populations, a product of limited seed dispersal and probably limited pollen dispersal. Although both theory and simulation studies predict that structure should be apparent where trees are isolated by distance, most studies of structure in natural populations have detected only a weak spatial genetic structuring. In this contribution, we compare the use of spatial autocorrelation methodology and F statistics with the concept of relatedness to examine the spatial genetic structure in the natural population of a native southern beech and to explore the...

Ano: 2011 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-16202011000300014 Genetic characterization of Japanese plum cultivars (Prunus salicina) using SSR and ISSR molecular markers Ciencia e Investigación Agraria Carrasco,Basilio; Díaz,Carole; Moya,Mario; Gebauer,Marlene; García-González,Rolando. The genetic characterization of 29 elite Japanese plum cultivars (Prunus salicina) and 4 Prunus cultivars was carried out by analyzing 97 Simple Sequence Repeat (SSR) alleles and 232 binary Inter Simple Sequence Repeat (ISSR) loci. A high level of genetic variability was found for these two molecular markers among the Japanese plum cultivars compared to other Prunus species. On average, the variability found by analyzing the SSR alleles were Na = 12.1, Ne = 5.2, Ho = 0.9, He = 0.8 and F= -0.127, whereas ISSR yielded values of h = 0.15 and I = 0.27. The genetic relationship among cultivars was estimated with Principal Coordinate Analysis (PCA) and a Bayesian clustering approach using the software program Structure. This program identified two subgroups... Tipo: Journal article Palavras-chave: AMOVA; Bayesian analysis; Genetic distance; PCA; Plum; Structure.
