Physical Map between Marker 8O7 and 146O17 on the Medicago truncatula Linkage Group 1 that Contains the NIP Gene
… truncatula NIP gene is located on M. truncatula Linkage Group 1. Informative recombinants showed crossovers that localize the NIP gene between markers 146O17 and 23C16D. Marker 164N9 co-segregates with the NIP gene, and the location of marker 164N9 is between markers 146O17 and 23C16D. Based upon …

Analyses of a genic male-sterile mutant in soybean
… mutants: ms1, ms2, ms3, ms4, ms5, or ms6. No linkage was detected between the male-sterile gene and flower color (W1 locus), or between the male-sterile gene and pubescence color (T1 locus). Developmental and enzymatic studies showed that sterility was caused by retention of the callose walls, …

Genetic Analysis of Quantitative Trait Loci Associated with Seed Sucrose Content Using Molecular Markers in an Interspecific Glycine Cross
… Nineteen marker loci, mapping to seven linkage groups (A1, A2, E, F, L1, I, and M), were significantly associated with seed sucrose content after screening 178 polymorphic genetic markers, including RFLPs, SSRs, RAPDs and morphological markers. The replicated field experiments were …

Investigation into X-STR haplotype frequencies for forensic human identification in South Africa
… 0.999999999. The haplotype diversity of all four linkage groups exceeded 0.993. Linkage group 1 was the most informative, with 421 unique haplotypes. Possible linkage disequilibrium was detected in five loci pairs in male samples and three loci pairs in female samples. However, it is expected that …

Characterization of a Morphological Mutant, M-134, and Two Conidia-shed Mutants, E-1 and K-44 of <em>Neurospora crassa</em>
… mapping of M-134 indicated that the mutant is in Linkage Group 1 and linked to <em>lys -4</em> by 9% recombination. The present study also mapped M-134 to the right of <em>lys-4</em> in Linkage Group 1 with the gene order <em>cys-9</em> M-134 <em>im-1</em> displaying 15.4% recombination between …

Molecular Mapping Of A Soybean Mosaic Virus (SMV) Resistance Gene In Soybean (Glycine Max)
… SMV. Rsv1 has been mapped to soybean molecular linkage group (MLG) F by using molecular markers. The purpose of this study is to investigate the location of Rsv3 gene on soybean map using molecular markers. The Rsv3 gene of soybean confers resistance to the most vurulent strains (G5-G7) of SMV. …

Characterization of the soybean genome in regions surrounding two loci for resistance to soybean mosaic virus
… has been mapped previously to the soybean F linkage group. Rsv4 is an SMV resistance locus independent of Rsv1 and confers resistance to all strains of SMV. This locus has not been mapped previously. The purpose of this study is to investigate the two genomic regions that contain these …

Development of the Limb in Mice Bearing the Mutant Gene: Hypodactyly (Hd).
… hindlimb digits.In 1966, Hypodactyly (symbol Hd; linkage group XI) occurred spontaneously in the inbred strain MYA/Hu (Hummel, 1971). Since the strain was homozygous for another mutant gene which interfered with classification of the new mutant, Hypodactyly was transferred by outcrossing to …

Quantitative Trait Loci (Qtl) Analysis Of Sulfur Sensitivity In Vitis Aestivalis-Derived 'Norton'
… under greenhouse conditions. Association and linkage mapping were conducted using single nucleotide polymorphisms (SNPs) and simple sequence repeat (SSR) markers, respectively. A major quantitative trait loci (QTL) for sulfur sensitivity was detected on linkage group 14 (LOD=15). …

Mapping and Characterization of Phytophthora sojae and Soybean Mosaic Virus Resistance in Soybean
… major quantitative trait loci (QTL) on molecular linkage group (MLG)-J (chromosome 16) and two minor QTL on MLG-I (chromosome 20) and -G (chromosome 18) were mapped using conventional molecular markers. Additionally, partial resistance to <i>P. sojae</i> was mapped in the same RIL population using …

Genetic studies of mutants of Neurospora crassa lacking ornithine transcarbamylase
… mutants, to be in a single com-plementation group and thus comprise a single gene locus, to be allelic or very closely linked with s, and to be on the second linkage group of the Neurospora genome. The mutant locus has been named arg-12 and s has been renamed arg-12s. arg-12 was shown to be …

Mapping nif genes of Rhodobacter capsulatus, and characterization of a mutant with a pleiotropic defect in nitrogen metabolism
… (Nif- ) have previously been mapped into six linkage groups (I-VI) by transduction with gene transfer agent (GTA). Because this vector carries only 4600 bp of DNA, linkage can only be demonstrated for short chromosomal distances. In order to demonstrate linkage on a larger scale, the self- …
