Patterns of pollen dispersal in a small population of Pinus sylvestris L. revealed by total-exclusion paternity analysis

Article Abstract:

Patterns of pollen dispersal were investigated in a small isolated, relict population of Pinus sylvestris L. consisting of 36 trees, where a total-exclusion battery comprising chloroplast and nuclear microsatellites was used to assign paternity to 813 seeds collected from 34 trees. The results showed that the number and distribution of potential pollen donors in small populations strongly influence the patterns of effective pollen dispersal.

Properties of AFLP markers in inheritance and genetic diversity studies of Pinus sylvestris L

Article Abstract:

Using the AFLP method with three Scots pine nucleotides produced large number of amplified bands. Such markers have been observed in 4 other crosses, with 83% of the bands mapping in at least one cross. The AFLP technique seems to be an efficient way to quickly generate large numbers of markers that permits constructing and comparing linkage maps.

High variability of chloroplast DNA in three Mediterranean evergreen oaks indicates complex evolutionary history

Article Abstract:

High variability of chloroplast DNA variation was studied in three evergreen Quercus species, Q. suber, Q. ilex L., and Q. coccifera L., of oaks. The results reported remarkable differences in haplotype richness between species.
