All current phylogenetic methods assume that DNA substitutions are independent among sites. However, ample empirical evidence suggests that the process of substitution is not independent but is, in fact, temporally and spatially correlated. The robustness of several commonly used phylogenetic methods to the assumption of independent substitution is examined. A compound Poisson process is used t...

Medicinal plants have high importance in medicine and pharmacogonosy because of their secondary metabolites. Essential oils, antioxidants and flavonoids are the major compounds of many medicinal plants. These compounds especially antioxidants can increase oxidation of DNA in response to wounds. Nowadays, progresses in biotechnology such as molecular markers were used for phylogenetic relationsh...

Background: Argas persicus has a great importance for health and veterinary, it can transmit many infectious agents such as Borrelia anserina (avian spirochetosis) and Aegyptianella pullorum. Distinguishing Argasidae due to close morphological relationship is difficult. OBJECTIVES: In the present study, we performed molecular analyses based on PCR and sequencing of Amplicon derived from 16S rRN...

Species of the genus Protelenomus Kieffer (Platygastroidea, Scelionidae) are phoretic egg parasitoids coreid bugs. The discovery, DNA sequencing, and molecular phylogenetic analysis a species on Cletus punctiger (Dallas) (Hemiptera, Coreidae) shows that is derived lineage Trissolcus Ashmead. treated as junior synonym new , T. siliangae Yan, Chen & Talamas, described from China.

The phylogenetic relationships among members of the Odonates were inferred from mitochondrial DNA 12S ribosomal RNA sequence data. These data show support for a monophyletic Anisoptera suborder, which are consistent with previous phylogenetic work performed on the group. However, the Zygoptera are paraphyletic based on mitochondrial DNA evidence. In particular, the family Lestidae appears more ...

The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...

Understanding the dynamics of genome rearrangements is a major issue of phylogenetics. Phy-logenetics is the study of species evolution. A major goal of the field is to establish evolutionaryrelationships within groups of species, in order to infer the topology of an evolutionary treeformed by this group and common ancestors to some of these species.In this context, having means...

A Gram-positive, acid-fast and rapidly growing rod, designated S2-37 T, that could form yellowish colonies was isolated from one soil sample collected cotton cropping field located in the Xinjiang region of China. Genomic analyses indicated strain T harbored T7SS secretion system very likely able to produce mycolic acid, which were typical features pathogenetic mycobacterial species. 16S rRNA-d...

Phylogenetics has a long history, with many contributions to the field actually predating Darwin. Genomics, in contrast, is barely a decade old. While these two fields may be disparate in their ages, each has much to contribute to the further development of the other. Phylogenetics provides a rich source of methodologies able to facilitate and enhance genomic research. Genome structure and func...

The phylogenetic structure of genus Micromonospora within actinomycetes was examined by analysing the gyrB sequences of 15 validly described species and four subspecies. All but one of the Micromonospora strains formed a tight cluster, as had previously been demonstrated by a 16S rDNA-based phylogenetic analysis. However, the intrageneric relationships deduced from the gyrB-based phylogeny were...
