Pollen contamination trends in a maturing Douglas-fir seed orchard

Creator:

Adams, W. T., Hipkins, Valerie D., Burczyk, J., and Randall, W. K.

Abstract:

Pollen contamination was investigated in one block (block 4) of a 10-block Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seed orchard complex in western Oregon. Blocks (25 clones each) represent different breeding zones; thus, contaminant pollen sources not only included the adjacent natural stand of Douglas-fir, but also other blocks within the...

Repeated sequences associated with inversions and length mutations in the chloroplast genomes of Pseudotsuga and Pinus

Creator:

Hipkins, Valerie D.

Abstract:

To help understand the mechanisms of conifer chloroplast genome evolution, we characterized the nucleotide sequences of Douglas-fir (Pseudotsuga menziesiz) and Monterey pine (Pinus radiata) chioroplast DNA that are associated with a length mutation hotspot and inversion. The chloroplast DNA ofthese two conifers are characterized by shared large inversions that are...
