Numerous DNA extraction methods failed to remove contaminants that interfere with
restriction digests of Cuphea DNA. The method described here removes those contaminants …

A survey of cpDNA restriction-site variation for 22 species representing five of the six
subfamilies of the palm family was conducted. Phylogenetic reconstructions based on the …

We used restriction fragment analysis of chloroplast, nuclear, and mitochondrial DNA to
study phylogeny in the genus Pinus. Total genomic DNA of 18 to 19 pine species that …

The variability in chloroplast DNA type of 20 Rubus genotypes was examined by Southern
hybridization. DNA extracted from the Rubus accessions was digested with two restriction …

A high frequency of paternal plastid transmission occurred in progeny from crosses among
normal green alfalfa plants. Plastid transmission was analyzed by hybridization of …

Allozyme differentiation at 13 loci was studied in populations of Pinus tabulaeformis, P.
densata, and P. yunnanensis from China. It was previously suggested that P. densata …

Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) ovules were used to study the method of
pollen tube formation and penetration of the nucellus, the movement of the body cell down …

Restriction fragment analysis and heterologous hybridization of chloroplast (cp) DNA was
used to develop species-specific markers for P. tabulaeformis, P. yunnanensis and P …

Chloroplast DNA (cpDNA) was purified from blue spruce (Picea pungens Engelm.) and
Engelmann spruce (P. engelmannii Parry ex Engelm.), and was digested with several …

Within-species variability of a restriction site in the chloroplast (cp) DNA in Pinus monticola
has been surveyed. Frequencies of two variants of the cp genome are significantly different …
