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 Fungal Cytochromesc

Yeast, 1997
The CYC1 gene encoding cytochrome c in the yeast Candida albicans was cloned by complementation of a cytochrome c-deficient mutant of Saccharomyces cerevisiae, and its DNA sequence was determined. The analysis of the amino acid sequences of cytochrome c from 14 fungal species and two isoforms from S.

Phylogenetic Relationships of a Large Marine Beggiatoa

Systematic and Applied Microbiology, 1999
Based upon 16S rRNA sequence and phenotypic similarities, a large, uncultured Beggiatoa sp. from the Bay of Concepción (Chile), is very closely related to the Chilean Thioploca species Thioploca araucae., whose filaments grow as sheathed bundles. The formation of sheathed filament bundles, the key character to distinguish the genus Thioploca from ...

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.

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.

Classification and Phylogenetic Relationships of Chalcidoidea

Chalcidoidea have a long history that dates back to mentions by Aristotle, but with the first chalcids described as other hymenopterans by Linnaeus. As species were correctly placed in later treatments, their early family classifications were diverse, even until very recently.

PHYLOGENETIC RELATIONSHIPS AMONG EXTANT BRACHIOPODS

Cladistics, 1995
Abstract—The monophyletic status of the Brachiopoda and phylogenetic relationships within the phylum have long been contentious issues for brachiopod systematists. The relationship of brachiopods to other lophophore‐bearing taxa is also uncertain; results from recent morphological and molecular studies are in conflict.

Phylogenetic relationships of theJuglandaceae

Plant Systematics and Evolution, 1994
A cladistic analysis of molecular data from the chloroplast generbcL was used to examine the taxonomic relationships of the walnut family (Juglandaceae). In addition, chemical and morphological data from a previous study byHufford (1992) were incorporated, expanded, and analyzed independently and in combination with the molecular data.

THE PHYLOGENETIC RELATIONSHIP OF OPHIOGLOSSACEAE

TAXON, 1988
SummaryThe systematic position of Ophioglossaceae was examined using available evidence from recent anatomical and morphological studies. Although the Ophioglossaceae are free‐sporing vascular plants like the Filicopsida, and are therefore commonly placed in that group, the character correlation of eustelic or sympodial primary vascular system of stem,

Phylogenetic relationships of the marsupials

Geobios, 1982
Abstract A phylogeny of the Metatheria, based on the synthesis of cranial, dental, and postcranial hard morphology, and external pedal morphoclines, is presented and discussed. The expanded concept Pediomyidae includes North American Cretaceous and most Palaeogene marsupials.
