Analysis of Phylogeny: a Case Study on Saururaceae
نویسندگان
چکیده
Phylogenetics is the study of the origin, development, and death of a taxon. It is a useful tool, for example, in the conservation of species. This chapter is an introduction to phylogenetics from the perspective of plant molecular biologists, using a case study on Saururaceae. Based on analysis using integrated data from DNA sequences and morphology, we also draw a surprising conclusion that Saururus is not the most primitive genus in Saururaceae, contradicting a long-held tradition of the field. We point out some deficiencies in the older studies.

Haplotype Block Partitioning and tagSNP Selection under the Perfect Phylogeny Model
Single Nucleotide Polymorphisms (SNPs) are the most usual form of polymorphism in human genome.Analyses of genetic variations have revealed that individual genomes share common SNP-haplotypes. Theparticular pattern of these common variations forms a block-like structure on human genome. In this work,we develop a new method based on the Perfect Phylogeny Model to identify haplo...
متن کاملA phylogeny analysis on six mullet species (Teleosti: Mugillidae) using PCR-sequencing method
In this study, genetic differences and phylogenic relationships among six Mugilidae species (Mugil cephalus, M. capito, Liza subviridis, L. saliens, L. aurata, Valamugil buchanani) were determined using PCR-sequencing. M. cephalus, L. subviridis, and V. buchanani from the Persian Gulf and Oman Sea, and L. aurata and L. saliens from the Caspian Sea were col-lected. Samples of an imported, Egypt...
متن کاملVerhuellia is a segregate lineage in Piperaceae: more evidence from flower, fruit and pollen morphology, anatomy and development.
BACKGROUND AND AIMS The perianthless Piperales, i.e. Saururaceae and Piperaceae, have simple reduced flowers strikingly different from the other families of the order (e.g. Aristolochiaceae). Recent molecular phylogenies proved Verhuellia to be the first branch in Piperaceae, making it a promising subject to study the detailed structure and development of the flowers. Based on recently collecte...
متن کاملGenetic Diversity and Molecular Phylogeny of Iranian Sheep Based on Cytochrome b Gene Sequences
Phylogenetic relationships and genetic variation between two Iranian sheep breeds were analyzed using cytochrome b (cyt-b) gene sequences. The genomic DNA was isolated by salting out method and amplified cytochrome b gene using polymerase chain reaction restriction (PCR) method with a pair of primer. A partial sequence of cyt-b gene of Iranian sheep is 780 bp and contained 13 variable sites and...
متن کاملMolecular Characterization and Phylogeny Analysis Based on Sequences of Cytochrome Oxidase gene From Hemiscorpius lepturus of Iran
Abstract: Background: Hemiscorpius lepturus is a medically important scorpion found along the Iranian borders, especially near to Khuzestan Province in the south-west of Iran. This is the only non-buthid scorpion which is potentially lethal in southern Iran and is responsible for severe dermonecrotic scorpionism. OBJECTIVES: In this study, DNA fragment of the mitochondrial cytochrome c oxidase ...
