Source/Description: Clones containing [CA]n microsatellites were selected with end-labelled [TG])5 from a flow-sorted chromosome 9 library (derived from a human/hamster hybrid cell line) in Charon 21 A. Southern blots of clones containing microsatellites were probed with either human or hamster DNA. Clone 9CMP1 containing a [CA]n microsatellite of human origin was sequenced enabling the design ...

Approximately 10% of Amyotrophic lateral sclerosis/ Motor Neuron Disease (ALS/MND) is inherited of which up to 20% is caused by mutations, (changes) in the superoxide dismutase 1 (SOD1) gene. Detailed bioinformatics study of all the known mutations in the SOD1 gene revealed interesting information. The information about all the experimentally proven mutations in the SOD1 gene was collected and ...

PREMISE OF THE STUDY The Million Orchid Project at Fairchild Tropical Botanic Garden is an initiative to propagate native orchids for reintroduction into Miami's urban landscapes. The aim of this study was to develop microsatellites for Encyclia tampensis and Cyrtopodium punctatum (Orchidaceae). METHODS AND RESULTS Ten microsatellites were developed for each species. For E. tampensis sampled ...

Microsatellites, or simple sequence repeats (SSRs), are one of the most informative and multi-purpose genetic markers exploited in plant functional genomics. However, the discovery of SSRs and development using traditional methods are laborious, time-consuming, and costly. Recently, the availability of high-throughput sequencing technologies has enabled researchers to identify a substantial num...

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...

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...

Using bioinformatics software and database, we have characterized the microsatellite pattern in the V. volvacea genome and compared it with microsatellite patterns found in the genomes of four other edible fungi: Coprinopsis cinerea, Schizophyllum commune, Agaricus bisporus, and Pleurotus ostreatus. A total of 1346 microsatellites have been identified, with mono-nucleotides being the most frequ...

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...

The MICdb (Microsatellites Database) (http://www.cdfd.org.in/micas) is a comprehensive relational database of non-redundant microsatellites extracted from fully sequenced prokaryotic genomes. The current version (1.0) of the database has been compiled from 83 genomes belonging to different phylogenetic groups. This database has been linked to MICAS, the web-based Microstatellite Analysis Server...

The evolutionary origins of microsatellites are not well understood. Some investigators have suggested that point mutations that expand repeat arrays beyond a threshold size trigger microsatellites to become variable. However, little empirical data has been brought forth on this and related issues. In this study, we examine the evolutionary history of microsatellites in six species within the o...
