Assessment and knowledge of the genetic diversity and variation within and between populations of rare and endangered plants is very important for effective conservation. Intergenic spacer sequences variation of psbA-trnH locus of chloroplast genome was assessed within Breonadia salicina (Rubiaceae), a critically endangered and endemic plant species to South western part of Kingdom of Saudi Ara...

The Asian cyprinid fish, the topmouth gudgeon (Pseudorasbora parva), was introduced into Europe in the 1960s. A highly invasive freshwater fish, it is currently found in at least 32 countries outside its native range. Here we analyse a 700 base pair fragment of the mitochondrial cytochrome b gene to examine different models of colonisation and spread within the invasive range, and to investigat...

Little is known about the number and rate of introductions into terrestrial and marine tropical regions, and if introduction patterns and processes differ from temperate latitudes. Botryllid ascidians (marine invertebrate chordates) are an interesting group to study such introduction differences because several congeners have established populations across latitudes. While temperate botryllid i...

We report the presence of mitochondrial DNA (mtDNA) hyperdiversity in the marine periwinkle Melarhaphe neritoides (Linnaeus, 1758), the first such case among marine gastropods. Our dataset consisted of concatenated 16S-COI-Cytb gene fragments. We used Bayesian analyses to investigate three putative causes underlying genetic variation, and estimated the mtDNA mutation rate, possible signatures o...

To analyze the genetic structure and diversity of Colletotrichum gloeosporioides as dominant species on Citrus, Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) diversity, including 63 strains isolated selected from 8 different sites 5 citrus species, was studied. A total 19 GAPDH haplotypes were identified by analysis, main haplotype (haplotype 5) distributed in 28 isolates, mainly Citrus unch...

Mitochondrial displacement loop (mt D-loop) sequence analyses have greatly improved assessments of genetic diversity, structure, and population dynamics endangered species threatened by climate change habitat loss. Tracking haplotypes these using mitochondrial-based markers has opened new avenues for conservation genomics biodiversity research. Recent studies used mt D-loop sequences to assess ...
