PHYLOGENETIC RELATIONSHIPS IN SEED PLANTS

Cladistics, 1985
Abstract— The phylogenetic relationships of nineteen extant and fossil seed plants are considered. Analysis of 31 characters produced ten topologically similar and equally parsimonious cladograms. A strict consensus tree derived from these cladograms places Lyginopteris as the sister taxon to the other seed plants included.

Phylogenetic relationships of Proteroglyphae toxins

Toxicon, 1972
Abstract The amino acid sequences of eleven Proteroglyphae toxins were used in setting up a phylogenetic relationship between these toxins. A probable sequence of genetic events leading to this relationship is postulated.

Phylogenetic relationships of Rhododendroideae (Ericaceae)

American Journal of Botany, 1997
The Rhododendroideae are usually recognized as a subfamily within Ericaceae. This group has been considered primitive (i.e., occupying the ancestral or basal position relative to all other Ericaceae) due to the occurrence of separate petals in several taxa, deciduous corollas, and septicidally dehiscent capsules.

Taxonomy and phylogenetic relationship of zokors

Journal of Genetics, 2020
Zokor (Myospalacinae) is one of the subterranean rodents, endemic to east Asia. Due to the convergent and parallel evolution induced by its special lifestyles, the controversies in morphological classification of zokor appeared at the level of family and genus.

Phylogenetic relationships among vertebrate visual pigments

Vision Research, 1994
Genomic DNA fragments in exon 4 of chicken, goldfish and salmon visual pigments were amplified by polymerase chain reaction, using oligonucleotide mixtures as primers, and hypothetical phylogenetic trees were drawn up from the deduced amino acid sequences.

1.5.2 Phylogenetic relationships

1996
Publisher Summary This chapter reviews previous concepts and offers some additional new thoughts about the phylogenetic relationships of Eriophyoidea with other lineages of mites, along with implications for the relative age of the group. It also reviews recent concepts about phylogenetic relationships among family-level groupings within the ...

Phylogenetic relationships among Vibrio anguillarum plasmids

Plasmid, 1984
Results of restriction endonuclease analysis and Southern blot hybridization suggest that the R-plasmids from Vibrio anguillarum strains isolated in Japan can be divided into at least four groups of homology depending on the time of their isolation and geographical source.

Phylogenetic relationships among Spanish goats breeds

Animal Genetics, 2005
SummaryWe partially sequenced the mitochondrial hypervariable region 1 (HVR1) in 60 goats belonging to six Spanish breeds. The analysis of these and previously published sequences reveals a weak phylogeographical structure in the Iberian Peninsula breeds. Individuals from a single breed did not group into a single cluster. Furthermore, individuals from

Phylogenetic Relationships of Angiosperms

2015
This chapter concentrates on angiosperms or flowering plants, which are considered the dominant land plants and sister to a group that includes all other extant seed plants. Angiosperms have a long fossil record going back to the earliest Cretaceous period, and they possibly originated during the Jurassic period more than 140 million years ago.

Phylogenetic Relationships of Dengue-2 Viruses

Virology, 1993
RNA oligonucleotide fingerprinting studies on a large number of virus isolates previously demonstrated considerable genetic variation in isolates of dengue (DEN)-2 serotype. We report the entire envelope (E) glycoprotein gene and deduced amino acid sequences of 16 DEN-2 viruses and the phylogenetic relationships of these, plus 17 additional published ...
