Abstract:
Genomic DNA from 84 individuals of Excoecaria agallocha from seven mangrove populations were analysed for random amplified polymorphic DNAs (RAPDs) using 16 random 10-mer primers. Polymorphism within populations varied from 20% to 31%. At the interpopulation level, 111/149 (74%) of RAPDs were polymorphic. Restriction fragment length polymorphism (RFLP) analysis of 21 individuals (3 individuals randomly selected from the 7 populations) using 30 probe-enzyme combinations revealed a high level of interpopulation polymorphism (62.2%) indicating interpopulation genetic divergence.

Abstract:
Bio -diversityrefers to the variations within the living world while genetic diversity is the sum of genetic characteristics within any species or genus. Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele. The population will continue for more generations because of the success of these individuals.

Abstract:
In marker assisted breeding programs, determination of genome polymorphism and development of suitable molecular markers is of the greatest importance. The aim of this research was development of RAPD markers, which will enable quick and cost efficient DNA polymorphism analysis among closely related sugar beet genotypes. The research was conducted on twelve sugar beet genotypes from population of closely related genotypes. Reactions with eight RAPD primers and five primer mixtures resulted in stable and reproducible bands in all samples, with 44 polymorphic and 14 monomorphic loci, and average

Moloundou (MOL) and Coffea pseudozanguebariae (PSE). The amplification percentages for these 110 primer pairs ranged from 72.7% for LIB to 86.4% for PSE. Good transferability was thus obtained within the Coffea genus. When focusing on the two species CAN and PSE, high genetic diversity, high polymorphic

Pawpaw (Asimina triloba) is a tree fruit native to eastern North America, which is in the early stages of domestication. Most early 20th century pawpaw cultivars have been lost; however, recent cultivar releases and potential new releases may have enhanced genetic diversity. The objective of this study was to compare the genetic variation exhibited among older and new pawpaw cultivars and Kentucky State University (KSU) advanced selections using simple sequence repeat (SSR) markers. Polymorphic microsatellite marker analysis was conducted with nine older pawpaw cultivars, six recently released

Abstract:
The authors have previously reported an efficient in vitro system for mass micropropagation of Robinia ambigua `idahoensis' (Idaho locust). Their method used enhanced branching of axillary buds from a single donor plant along with detection of somaclonal variation by the intersimple sequence repeat (ISSR) markers. Because ISSRs tend to be clustered to specific chromosomal regions in plant genomes, the extent and scope of the genomic variations and the sequences underlying the variation warranted further investigations.

Abstract:
Genome sequencing has uncovered tremendous sequence variation within and between species. In plants, in addition to large variations in genome size, a great deal of sequence polymorphism is also evident in several large multi-gene families, including those involved in the ubiquitin-26S proteasome protein degradation system. However, the biological function of this sequence variation is yet not clear. In this work, we explicitly demonstrated a single origin of retroposed Arabidopsis Skp1-Like (ASK) genes using an improved phylogenetic analysis. Taking advantage of the 1,001 genomes project, we

Abstract:
Muscarinic M2 and M3 receptors are important for the development of airway hyperresponsiveness in asthma. While there is currently no evidence to suggest altered function of M3 receptors in airway disease, a dysfunctionality of M2 receptors has been reported to occur in asthmatic patients. Current studies suggest that this dysfunctionality may be caused by allosteric modulation induced by endogenous mediators released by pro-inflammatory cells in inflamed airways. However, it is not known whether genetic variation in the coding or transcriptional regulatory regions of the gene contributes to t

Abnormal regulation of complement is intimately associated with C3 glomerulopathy and atypical haemolytic uraemic syndrome. Atypical haemolytic uraemic syndrome is characterized by renal thrombotic microangiopathy due to an inability to regulate complement activation along the renal endothelium. The development of thrombosis is critically dependent on the ability to activate C5. Eculizumab, a monoclonal anti-C5 antibody, is an effective therapy for this condition.
