Recent technical advances allow straightforward access to genetic information directly drawn from DNA. The present article highlights the suitability of high variation molecular genetic markers, such as microsatellites, for studies relevant to amphibian conservation. Molecular markers appear particularly useful for i) measuring local gene flow and migration, ii) assigning individuals to their m...

nuclear markers such as microsatellites have allowed the identification of conservation and management populations of the hawksbill turtles. in present study, eight microsatellite loci were studied. 60 samples of hawksbill turtles. flipper from shidvar and hormuz islands have been surgically removed and preserved in 20% dmso buffer. dna was extracted using dnp kit and amplified by pcr methods. ...

Sex chromosomes are an ideal system to study processes connected with suppressed recombination. We found evidence of microsatellite expansion, on the relatively young Y chromosome of the dioecious plant sorrel (Rumex acetosa, XY1Y2 system), but no such expansion on the more ancient Y chromosomes of liverwort (Marchantia polymorpha) and human. The most expanding motifs were AC and AAC, which als...

Paracoccidioides brasiliensis, a thermodimorphic fungus, is the causative agent of the prevalent systemic mycosis in Latin America, paracoccidioidomycosis (PCM). Here, we describe the microsatellite patterns observed in a collection of P. brasiliensis random sequence tags. We identified 1,117 microsatellite patterns in about 3.8 Mb of unique sequences (0.47% of the total DNA used in the analysi...

The mesquite lizard (Sceloporus grammicus) exhibits multiple Robertsonian chromosomal rearrangements (mainly centric fissions) resulting in several cytotypes. In a transitional environment from oak-pine forests to a drier xeric habitat in central Mexico, two cytotypes (F5: 2n = 34 and FM2: 2n = 46) are known to hybridize. A partial genomic library was constructed from S. grammicus genomic DNA a...

We compared genetic differentiation among populations of the threatened massasauga rattlesnake (Sistrurus c. catenatus) using two types of nuclear molecular markers: randomly amplified polymorphic DNA (RAPD) markers and microsatellites. Analyses of molecular variance (AMOVA) and G(ST) and F(ST) analyses indicated that levels of among-population differentiation between regional populations (>100...

Bretschneidera sinensis is an endangered species that is mainly distributed in South China. As a tertiary relict and the single species in the Bretschneideraceae family, it has a high conservation value. To investigate the influence of human disturbance on its mating system, 63 new microsatellites were developed using restriction-site-associated DNA sequencing and their polymorphisms were teste...

Microsatellite markers (also known as SSRs, Simple Sequence Repeats) are widely used in plant science and are among the most informative molecular markers for population genetic investigations, but the development of such markers presents substantial challenges. In this report, we discuss how next generation sequencing can replace the cloning, Sanger sequencing, identification of polymorphic lo...

Microsatellites are DNA sequences consisting of repeated, short (1-6 bp) sequence motifs that are highly mutable by enzymatic slippage during replication. Due to their high intrinsic variability, microsatellites have important applications in population genetics, forensics, genome mapping, as well as cancer diagnostics and prognosis. The current analytical standard for microsatellites is based ...
