Analysis of the genetic diversity of super sweet corn inbred lines using SSR and SSAP markers
, “Analysis of the genetic diversity of super sweet corn inbred lines using SSR and SSAP markers”, vol. 15, p. -, 2016.
In this study, we compared the efficiency of simple sequence repeat (SSR) and sequence specific amplified polymorphism (SSAP) markers for analyzing genetic diversity, genetic relationships, and population structure of 87 super sweet corn inbred lines from different origins. SSR markers showed higher average gene diversity and Shannon’s information index than SSAP markers. To assess genetic relationships and characterize inbred lines using SSR and SSAP markers, genetic similarity (GS) matrices were constructed.
Genetic differentiation of Octopus minor (Mollusca, Cephalopoda) off the northern coast of China as revealed by amplified fragment length polymorphisms
, “Genetic differentiation of Octopus minor (Mollusca, Cephalopoda) off the northern coast of China as revealed by amplified fragment length polymorphisms”, vol. 14, pp. 15616-15623, 2015.
Octopus minor (Sasaki, 1920) is an economically important cephalopod that is found in the northern coastal waters of China. In this study, we investigated genetic differentiation in fishery populations using amplified fragment length polymorphisms (AFLPs). A total of 150 individuals were collected from five locations: Dalian (DL), Yantai (YT), Qingdao (QD), Lianyungang (LY), and Zhoushan (ZS), and 243 reproducible bands were amplified using five AFLP primer combinations. The percentage of polymorphic bands ranged from 53.33 to 76.08%.
Genetic diversity, population structure, and association mapping of agronomic traits in waxy and normal maize inbred lines
, “Genetic diversity, population structure, and association mapping of agronomic traits in waxy and normal maize inbred lines”, vol. 14, pp. 7502-7518, 2015.
Understanding genetic diversity, population structure, and linkage disequilibrium is a prerequisite for the association mapping of complex traits in a target population. In this study, the genetic diversity and population structure of 40 waxy and 40 normal inbred maize lines were investigated using 10 morphological traits and 200 simple sequence repeat (SSR) markers. Based on a population structure analysis, the 80 maize inbred lines were divided into three groups: I, II, and admixed.
Genetic diversity of the endemic flat-needle pine Pinus krempfii (Pinaceae) from Vietnam revealed by SSR markers
, “Genetic diversity of the endemic flat-needle pine Pinus krempfii (Pinaceae) from Vietnam revealed by SSR markers”, vol. 14, pp. 7727-7739, 2015.
Pinus krempfii Lecomte (Pinaceae) is an endemic tree to Vietnam with restricted habitats at higher altitudes in the highlands. In this study, genetic variation of four populations of P. krempfii was assessed using 17 microsatellite markers (single sequence repeats). Of these 17 markers, eight were polymorphic, and among the 42 putative alleles amplified, 32 were polymorphic (accounting for 76.19%).
Estimation of genetic structure of a Mycosphaerella musicola population using inter-simple sequence repeat markers
, “Estimation of genetic structure of a Mycosphaerella musicola population using inter-simple sequence repeat markers”, vol. 14, pp. 8046-8057, 2015.
Among the diseases affecting banana (Musa sp), yellow Sigatoka, caused by the fungal pathogen Mycosphaerella musicola Leach, is considered one of the most important in Brazil, causing losses throughout the year. Understanding the genetic structure of pathogen populations will provide insight into the life history of pathogens, including the evolutionary processes occurring in agrosystems.
Genetic bottlenecks in Turkish okra germplasm and utility of iPBS retrotransposon markers for genetic diversity assessment
, “Genetic bottlenecks in Turkish okra germplasm and utility of iPBS retrotransposon markers for genetic diversity assessment”, vol. 14, pp. 10588-10602, 2015.
Lack of requisite genetic variation in Turkish okra has necessitated the use of different types of markers for estimating the genetic diversity and identifying the source of variation. Transposable elements, present abundantly in plant genomes, generate genomic diversity through their replication and are thus an excellent source of molecular markers. We hypothesized that inter-primer binding site (iPBS)-retrotransposons could be the source of variation because of their genome plasticity nature.
Isolation and characterization of novel polymorphic microsatellite markers for Lutjanus erythropterus
, “Isolation and characterization of novel polymorphic microsatellite markers for Lutjanus erythropterus”, vol. 14, pp. 10944-10947, 2015.
We isolated and characterized 22 polymorphic microsatellite loci in the crimson snapper (Lutjanus erythropterus) using a (GT)13-enriched genomic library. We found three to 15 alleles per locus, with a mean of 6.68. The observed and expected heterozygosities ranged from 0.087 to 0.978 and from 0.125 to 0.904, respectively, with averages of 0.576 and 0.650, respectively. Only three loci showed significant deviation from the Hardy-Weinberg equilibrium after Bonferroni correction. Four loci showed evidence for null alleles.
