High density molecular linkage map is a prerequisite to identify the quantitative traits loci. Construction of linkage maps, using mapping populations derived from two major subspecies: indica and japonica in rice, have been reported. However, limited work was conducted in indica subspecies. Present studies focused to construct a molecular map based on indica × indica (Shaheen Basmati × Pokkali...
Detailed analysis of the inheritance of molecular markers was performed in the oomycete plant pathogen Phytophthora infestans. Linkage analysis in the sexual progeny of two Dutch field isolates (cross 71) resulted in a high-density map containing 508 markers on 13 major and 10 minor linkage groups. The map showed strong clustering of markers, particularly of markers originating from one parent,...
Linkage maps enable the study of important biological questions. The construction of high-density linkage maps appears more feasible since the advent of next-generation sequencing (NGS), which eases SNP discovery and high-throughput genotyping of large population. However, the marker number explosion and genotyping errors from NGS data challenge the computational efficiency and linkage map qual...
High-density linkage maps provide powerful tools for studying the genetic basis of ecologically relevant adaptations and the genomic scope of introgression. We backcrossed an F(1) hybrid male Papilio glaucus/Papilio canadensis tiger swallowtail butterfly to a pure P. glaucus female and constructed amplified fragment length polymorphism linkage maps from the progeny. The paternal map contains 30...
A microsatellite-based high-density genetic map facilitates for fine mapping of hereditary traits of interest, characterization of meiosis, and providing a foundation for physical map construction. Here, we developed a comprehensive genetic map on the basis of >880,000 genotypes across the USDA MARC cattle reference families with a potential genetic resolution of 0.8 cM at the 95% confidence le...
Construction of genetic linkage map is essential for genetic and genomic studies. Recent advances in sequencing and genotyping technologies made it possible to generate high-density and high-resolution genetic linkage maps, especially for the organisms lacking extensive genomic resources. In the present work, we constructed a high-density and high-resolution genetic map for channel catfish with...
We have leveraged the reference sequence of a boxer to construct the first complete linkage map for the domestic dog. The new map improves access to the dog's unique biology, from human disease counterparts to fascinating evolutionary adaptations. The map was constructed with approximately 3000 microsatellite markers developed from the reference sequence. Familial resources afforded 450 mostly ...
Physical mapping of BACs by fluorescent in situ hybridization (FISH) was used to analyze the liguleless (lg-1) linkage group in sorghum and compare it to the conserved region in rice and maize. Six liguleless-associated rice restriction fragment length polymorphism (RFLP) markers were used to select 16 homeologous sorghum BACs, which were in turn used to physically map the liguleless linkage gr...
Olive flounder, Paralichthys olivaceus, is an important fish species in Asia, both for fisheries and aquaculture. As the first step for better understanding the genomic structure and functional analysis, we constructed a genetic linkage map for olive flounder based on 180 microsatellites and 31 expressed sequence tag (EST)-derived markers. Twenty-four linkage groups were identified, consistent ...
