The influence of fruit ripeness (half ripe, fully ripe, overripe) at the time of seed extraction on seed germination behaviour, at 25 °C and 13 °C, was studied in two Spanish pepper cultivars for canning. Seeds from half ripe fruits had a poorer behaviour than those taken from fully ripe fruits, especially at 13 °C. Room ripening and overripening of half ripe fruits improved the germination behaviour of the seeds although this behaviour was poorer than that of seeds extracted from fully ripe fruits that were allowed to overripen. Overripening of fully ripe picked fruits slightly improved germination behaviour.  相似文献   

Bayesian analysis of quantitative trait loci for boar taint in a Landrace outbred population     

Varona L  Vidal O  Quintanilla R  Gil M  Sánchez A  Folch JM  Hortos M  Rius MA  Amills M  Noguera JL 《Journal of animal science》2005,83(2):301-307

The genetic basis of the main components of boar taint was investigated in intact male pigs in a commercial population. We analyzed fat androsten-one and skatole concentrations from 217 males of an outbred Landrace population. Records were normalized using a logarithm transformation and tested for normality using a Wilk-Shapiro test. Bayesian analysis was then used to map QTL in 10 candidate regions previously selected on chromosomes 1, 2, 3, 4, 6, 7, 8, 9, 10, and 13. The criterion for QTL detection was the Bayes factor (BF) between polygenic models with and without QTL effects. Both traits had considerable genetic determination, with posterior means of total heritabilities ranging from 0.59 to 0.73 for androstenone and from 0.74 to 0.89 for skatole. Positive evidence for a fat skatole QTL was detected on SSC6 (BF = 5.16); however, no QTL for androstenone were found in any of the 10 chromosomal regions analyzed. With the detection of a QTL for the fat skatole concentration segregating in this population, marker-assisted selection or even gene-assisted selection could be used once the causal mutation of the QTL was identified.  相似文献   

Identification of carcass and meat quality quantitative trait loci in a Landrace pig population selected for growth and leanness   总被引：1，自引：0，他引：1

The identification of QTL related to production traits that are relevant for the pig industry has been mostly performed by using divergent crosses. The main objective of the current study was to investigate whether these growth, fatness, and meat quality QTL, previously described in diverse experimental populations, were segregating in a Landrace commercial population selected for litter size, backfat thickness, and growth performance. We have found QTL for carcass weight (posterior P > 0.75), cutlet weight (posterior P > 0.99), weight of ham (posterior P > 0.75), shoulders weight (posterior probability > 0.99), and shear firm-ness (posterior P > 0.99) on pig Chromosome 2. Moreover, QTL with posterior P > 0.75 for fat thickness between the 3rd and 4th ribs (Chromosome 7), rib weights (Chromosome 8), backfat thickness (Chromosomes 8, 9, and 10), and b Minolta color component (Chromosome 7) were identified. These results indicate that commercial purebred populations retain a significant amount of genetic variation, even for traits that have been selected for many generations.  相似文献   

Anatomy of the cranioencephalic structures of the camel (Camelus dromedarius L.) by imaging techniques: a magnetic resonance imaging study     

Arencibia A  Rivero MA  Gil F  Ramírez JA  Corbera JA  Ramírez G  Vázquez JM 《Anatomia, histologia, embryologia》2005,34(1):52-55

The objective of this study was to define the anatomy of the cranioencephalic structures and associated formations in camel using magnetic resonance imaging (MRI). MR images were acquired in sagittal, transverse and oblique dorsal planes, using spin-echo techniques, a magnet of 1.5 T and a standard human body coil. MR images were compared with corresponding frozen cross-sections of the head. Different anatomic structures were identified and labelled at each level. The resulting images provided excellent soft tissue contrast and anatomic detail of the brain and associated structures of the camel head. Annotated MR images from this study are intended to be a reference for clinical imaging studies of the head of the dromedary camel.  相似文献   

Seroepidemiology of neosporosis in dairy cattle in Uruguay     

Kashiwazaki Y  Gianneechini RE  Lust M  Gil J 《Veterinary parasitology》2004,120(1-2):139-144

A seroepidemiological survey of Neospora caninum was done in a dairy farm in Uruguay employing indirect fluorescent antibody test (IFAT). Sera from 217 cattle (155 cows, 31 heifers and 31 calves) were tested for N. caninum antibodies in July 2000 and it was found that abortions were significantly associated with the seropositivity of the cows by chi(2)-test (P = 0.025). The cows with an IFAT titre of 1:3200 were at a significantly higher risk of abortion than seronegative cows (P = 0.0013). Neospora organisms were detected in the brains of two aborted foetuses by immunohistochemical examination. The infection of N. caninum was considered postnatal because of the even distribution of seropositive cows (60%), low seroprevalence (20%) in calves and no significant correlation in the serostatus between calves and their dams (P = 0.43). A fitted binomial generalised linear model revealed that there was an increasing risk of abortion with increasing IFAT titre and increasing age between 2 and 6 years.  相似文献   

Molecular diversity of Moraxella bovis isolated from Brazil, Argentina and Uruguay over a period of three decades     

Conceição FR  Dellagostin OA  Paolichi F  Leturia AC  Gil Turnes C 《Veterinary journal (London, England : 1997)》2004,167(1):53-58

The molecular profile of 30 Moraxella bovis strains, recovered from outbreaks of infectious bovine keratoconjunctivitis in Argentina, Brazil and Uruguay between 1974 and 2001, was determined through randomly applied polymorphic DNA (RAPD) analysis. Molecular profiles of nine strains recovered after 1990 varied from those recovered before 1990. The profiles of 13 strains (48%) differed from those of three vaccinal strains extensively used since 1984 in Argentina and Uruguay. Eight Argentinean strains, one from Brazil and two from Uruguay had identical RAPD profiles. Strains belonging to different serogroups had identical RAPD profiles, demonstrating that this technique was not able to discriminate among strains with low cross-reactivity indices. RAPD may be helpful in the primary characterization of M. bovis strains, but it does not replace serological characterization.  相似文献

Correlation of magnetic resonance images with anatomic features of the equine tarsus     

Latorre R  Arencibia A  Gil F  Rivero M  Henry RW  Ramírez G  Váquez JM 《American journal of veterinary research》2006,67(5):756-761

OBJECTIVE: To correlate anatomic features of the equine tarsus identified in plastinated sections with images obtained via magnetic resonance imaging (MRI). ANIMALS: 4 horses. PROCEDURE: MRI (1.5-Tesla magnet) of the tarsus was performed on the pelvic limbs of 4 clinically normal horses following euthanasia. After imaging, tarsocrural joint spaces and vasculature were injected with colored latex. Sagittal and transverse sections of the tarsi were plastinated to facilitate interpretation of MR images. RESULTS: Relevant anatomic structures were identified and labeled on the plastinated tissue slices and corresponding MR images. Results indicated high correlations between MRI findings and those of plastinated sections. CONCLUSIONS AND CLINICAL RELEVANCE: The data obtained provided certain reference standards for normal anatomic structure sizes and positions in the equine tarsus. This information may aid future physiologic or clinical studies of this joint.  相似文献   

Co‐infection with Cucumber vein yellowing virus and Cucurbit yellow stunting disorder virus leading to synergism in cucumber     

F. M. Gil‐Salas  J. Peters  N. Boonham  I. M. Cuadrado  D. Janssen 《Plant pathology》2012,61(3):468-478

Symptom expression and levels of the ipomovirus Cucumber vein yellowing virus (CVYV) and the crinivirus Cucurbit yellow stunting disorder virus (CYSDV) were compared in greenhouse cucumbers in single and mixed infections. Results were contrasted with those obtained for plants infected with the potyvirus Zucchini yellow mosaic virus (ZYMV) in single and in mixed infections with either CVYV or CYSDV. Cucumber showed leaf symptoms of each co‐infecting virus, except for the combination of CYSDV with ZYMV, where the typical CYSDV‐like symptoms of interveinal leaf yellowing were inconspicuous or absent. The progression of CVYV as quantified by real‐time RT‐PCR was similar in plants with single infections and in mixed infection with CYSDV between 15 and 60 days post‐inoculation (dpi). However, CYSDV was detected at significantly enhanced levels in plants when co‐infected with CVYV but not when co‐infected with ZYMV. In the latter case, ZYMV levels were reduced when compared with single infections. During mixed infections of ZYMV and CVYV, the titre levels of the ipomovirus were significantly lower when compared with single infections. Cucumber had reduced plant height, internode length, dry weight and fruit yield, positively correlated with the titre levels of CVYV and not of CYSDV during mixed infections. It is concluded that co‐infections with CVYV enhance the titre of CYSDV, which could have epidemiological significance.  相似文献
