A linkage map of the porcine genome has been developed by segregation analysis of 239 genetic markers. Eighty-one of these markers correspond to known genes. Linkage groups have been assigned to all 18 autosomes plus the X Chromosome (Chr). As 69 of the markers on the linkage map have also been mapped physically (by others), there is significant integration of linkage and physical map data. Six informative markers failed to show linkage to these maps. As in other species, the genetic map of the heterogametic sex (male) was significantly shorter (16.5 Morgans) than the genetic map of the homogametic sex (female) (21.5 Morgans). The sex-averaged genetic map of the pig was estimated to be 18 Morgans in length. Mapping information for 61 Type I loci (genes) enhances the contribution of the pig gene map to comparative gene mapping. Because the linkage map incorporates both highly polymorphic Type II loci, predominantly microsatellites, and Type I loci, it will be useful both for large experiments to map quantitative trait loci and for the subsequent isolation of trait genes following a comparative and candidate gene approach. 相似文献

The present study aims to characterize and compare the diet of bigeye and yellowfin tunas caught on aggregated schools in the western equatorial Atlantic Ocean. The samples were collected from January 2011 to June 2016. The tunas were measured on board and the stomachs were removed after evisceration. The stomachs were analyzed regarding their Index of Fullness and the importance of each prey in the diet was estimated by the Index of Relative Importance (IRI). The diet overlap was assessed by the Morisita‐Horn's Index, Non‐Metric Multidimensional Scale (NMDS), and Analysis of Similarity (ANOSIM). The feeding strategy was determined by the Costello's Diagram. The 195 bigeye and 212 yellowfin tunas ranged in fork length from 51 to 137 cm and 43 to 174 cm, respectively. The diet of bigeye tuna was composed of 10 families of fish, three cephalopod families, and four crustacean orders. The diet of yellowfin tuna was composed of 11 families of fish, three cephalopod families, and three crustacean orders. The yellowfin tuna seems to feed upon more abundant prey species near the surface like flying fish, which have the concentration enhanced by the light attractors on the boat, and occasionally on other prey from deeper habitats like lanternfish, squids, and pomfret. Bigeye tuna feed mainly at prey that commonly occurs in deeper habitats like squids, drift fish, lanternfish, and pomfret. 相似文献

We developed a procedure to isolate DNA from dried corncobs. This DNA was amplified successfully by PCR, producing well-defined
bands in response to specific primers. The SSR patterns between cob and leaf DNA of the same inbred line were found to be
identical, indicating that the DNA in the cob cells had not degraded during senescence. 相似文献

Background
Short tandem repeat polymorphisms (STRPs) are powerful tools for gene mapping and other applications. A STRP genome scan of 10 cM is usually adequate for mapping single gene disorders. However mapping studies involving genetically complex disorders and especially association (linkage disequilibrium) often require higher STRP density. 相似文献5.

Type 2 diabetes is a serious, genetically influenced disease for which no fully effective treatments are available. Identification of biochemical or regulatory pathways involved in the disease syndrome could lead to innovative therapeutic interventions. One way to identify such pathways is the genetic analysis of families with multiple affected members where disease predisposing genes are likely to be segregating. We undertook a genomewide screen (389-395 microsatellite markers) in samples of 835 white, 591 Mexican American, 229 black, and 128 Japanese American individuals collected as part of the American Diabetes Association's GENNID study. Multipoint nonparametric linkage analyses were performed with diabetes, and diabetes or impaired glucose homeostasis (IH). Linkage to diabetes or IH was detected near markers D5S1404 (map position 77 cM, LOD = 2.80), D12S853 (map position 82 cM, LOD = 2.81) and GATA172D05 (X-chromosome map position 130 cM, LOD = 2.99) in whites, near marker D3S2432 (map position 51 cM, LOD = 3.91) in Mexican Americans, and near marker D10S1412 (map position 14 cM, LOD = 2.39) in African Americans mainly collected in phase 1 of the study. Further analyses showed evidence for interactions between the chromosome 5 locus and region on chromosome 12 containing the MODY 3 gene (map position 132 cM) and between the X-chromosome locus and region near D12S853 (map position 82 cM) in whites. Although these results were not replicated in samples collected in phase 2 of the GENNID study, the region on chromosome 12 was replicated in samples from whites described by Bektas et al. (1999). 相似文献

Chromosomal aberrations are a common cause of multiple anomaly syndromes that include developmental and growth retardation. Current microscopic techniques are useful for the detection of such aberrations but have a limit of resolution that is above the threshold for phenotypic effect. We hypothesized that a genomewide microsatellite screen could detect chromosomal aberrations that were not detected by standard cytogenetic techniques in a portion of these individuals. To test this hypothesis, we performed a genomewide microsatellite screen of patients, by use of a currently available genetic-marker panel that was originally designed for meiotic mapping of Mendelian traits. We genotyped approximately 400 markers on 17 pairs of parents and their children who had normal karyotypes. By using this approach, we detected and confirmed two cases of segmental aneusomy among 11 children with multiple congenital anomalies. These data demonstrate that a genomewide microsatellite scan can be used to detect chromosomal aberrations that are not detected by microscopic techniques. 相似文献

Plasma and urine amino acids were determined by ion-exchange chromatography in 80 healthy preterm infants divided into three
groups: (1) 23 0/7–28 0/7, (2) 28 1/7–32 0/7 and (3) 32 1/7–35 0/7 weeks of gestation. Samples were collected from days 5
to 57 of life, when infants were exclusively orally fed. Infants with evidence of underlying diseases were excluded. Concentrations
of most plasma amino acids increased with gestational and maturational age; urinary excretion followed an opposite course.
Few amino acids depended on postnatal age. Plasma amino acids did not correlate inversely to their counterparts in urine indicating
that plasma amino acids do not simply reflect kidney function. Some amino acids in blood and urine were linked to nutrient
intake and body weight. Our data clearly indicate the heterogeneity of the preterm cohort; therefore, gestational age-matched
reference values have to be used for diagnostic purposes in preterm infants. 相似文献

This article examines the combined influence of cognitions (i.e., impact beliefs) and affect (i.e., feelings) on normative
beliefs (i.e., support for management options) about wolves and brown bears. Data were obtained from stratified random face-to-face
interviews (n = 1,611). The survey was conducted in the Abruzzo Lazio and Molise National Park (central Italy), where people have a long
history of coexistence with large carnivores. Knowledge was hypothesized to moderate the relationships of beliefs and feelings
on support for management actions. Path analyses supported the role of affect in mediating perceived impact beliefs and support
for the protection of large carnivores. Knowledge moderated these relationships in the case of wolves but not brown bears.
Residents of the national park had more knowledge about bears than wolves, which might partly explain both the stronger effect
that knowledge had on the affective component and its lack of a moderating effect on the bear model. Overall, our findings
show the positive attitude of residents toward large carnivores and support the idea of affect being more important than cognition
in predicting normative beliefs. 相似文献

During embryonic development of Musca domestica inactive ornithine decarboxylase protein appears in the embryos at 6 h postoviposition, increases in concentration and reaches a maximum level at 9 h postoviposition. The inactive enzyme is associated with the plasma membrane and appears to be the precursor for active ornithine decarboxylase, which is associated with the cytosolic fraction just prior to hatching. Both ornithine decarboxylase protein and enzymatic activity disappear during the early larval stage of this insect. 相似文献
