Electrophoretic Evidence and Plant Systematics

Applications of Electrophoretic Data in Avian Systematics

ABSTR^CT.--This paper is a survey of applications of electrophoretic techniques in ornithology, with an emphasis on post-1970 publications. The majority of electrophoretic studies of birds have been limited in a variety of ways. Many have dealt with "domesticated" species or have been limited to the examination of blood and/or egg-white proteins. Problems in comparing results from different stu...

Genomics, bioinformatics, and plant systematics

Genomics and bioinformatics are emerging disciplines that have the potential to fundamentally alter current approaches to molecular systematics. The sequencing of eukaryotic genomes has demonstrated the ability to obtain and interpret nucleotide sequences at a scale and efficiency that was unimaginable just a few years ago. The immense amount of sequence information generated by genome projects...

Plant Systematics: Beginnings and Endings

Zea systematics: ribosomal ITS evidence.

Ribosomal internal transcribed spacer (ITS) sequences were used to evaluate the phylogenetics of Zea and Tripsacum. Maximum likelihood and polymorphism parsimony were used for phylogenetic reconstructions. Zea ITS nucleotide diversity was high compared to other plant species, but approximately equivalent to other maize loci. Coalescence of ITS alleles was rapid relative to other nuclear loci; h...

Plant systematics in the age of genomics.

As plant biologists enter a new era in which comparative genomics promises to address fundamental questions in botany, such as unraveling metabolic and regulatory networks, the inestimable value and usefulness of robust systematic studies quickly become clear. In simplest terms, systematic studies can indicate which genomes in the plant kingdom to search, sample, and study for the answers to qu...
