To elucidate the genetic mechanism of hybrid lethality observed in hybrids between cultivated tobacco, Nicotiana tabacum, and wild tobacco species in the section Suaveolentes, genetic analyses were conducted through the triple cross of the hybrids of wild species, including N. benthamiana and N. fragrans, and N. tabacum. N. benthamiana and N. fragrans produced only viable hybrids after crossing with N. tabacum. Subsequently, N. benthamiana and N. fragrans were crossed with N. africana, N. debneyi, and/or N. suaveolens, which produced inviable hybrids after crossing with N. tabacum. Hybrids of the wild species were obtained from four of the six cross combinations. Only when hybrid plants of N. debneyi × N. fragrans, whose hybridity was confirmed by morphological characteristics, random amplified polymorphic DNA analysis, and chromosome observation, were crossed with N. tabacum, triple hybrids were obtained and segregated 1:1 (lethal:viable). Based on these results, a single dominant gene, designated Hybrid Lethality A1 (HLA1), in N. debneyi was found to control hybrid lethality by the interaction with gene(s) on the Q chromosome in N. tabacum. This represents the first report to identify a causal gene for hybrid lethality in the genus Nicotiana. 相似文献

A study was conducted to investigate the protective and therapeutic effects of crude garlic (Allium sativum) against experimental infection with Eimeria stiedae in rabbits. Forty rabbits were divided into four groups of ten rabbits each: a healthy control group (HC); a challenged-garlic-protected group (CGP) which received a daily dose of 0.5 g/kg body weight (bwt) crude garlic for five successive days before challenge with E. stiedae; a challenged-garlic-treated group (CGT) which was treated with a daily dose of 0.5 g/kg bwt crude garlic for five successive days post-challenge; and an infected control group (IC). The challenge dose was 5?×?104 sporulated E. stiedae oocysts per rabbit. Mortality rate, body weight gain, feed conversion ratio and faecal oocyst count were evaluated throughout the experiment. At the end of the experiment, all rabbits were killed and histopathological examination was performed. No mortalities were recorded in the HC and CGP groups, whilst mortality was found to be 20% and 40% in the CGT and IC groups, respectively. CGP rabbits had better body weight gain and lower numbers of oocysts than those in the CGT and IC groups. Hepatic lesions were less severe in the CGP group than in the CGT and IC groups. These results showed that oral administration of crude garlic ameliorated the adverse impacts of hepatic coccidiosis on rabbits when used as a prophylactic, but garlic was less effective as a therapeutic. 相似文献

Pasteurella multocida, serovar A: 3, selected by pathogenicity in mice from among 10 strains isolated from pneumonic lesions of calves, was adjusted to 10(7), 10(8) and 10(10) colony-forming units (CFU), and inoculated intratracheally into four calves. All calves showed pyrexia and had lungs with congestion and hepatization. Inoculation with 10(10) CFU of bacteria produced respiratory symptoms and abscesses in lungs. This information will aid elucidation of the pathogenicity of P. multocida and the development of vaccines. 相似文献

We investigated clonal and site variations in wood fiber length, microfibril angle, and specific gravity of seven natural
hybrid clones of Acacia (Acacia mangium × Acacia auriculiformis) grown in northern and southern Vietnam. Fiber length did not differ between clones or between sites. The microfibril angle
of the S2 layer did not significantly differ between clones but significantly differed between sites. Clone and site significantly
affected specific gravity. The significant effects of genetic × environmental interactions on wood properties indicated the
difference in the response of clones to different growing conditions. The trends of changes in fiber length, microfibril angle,
and specific gravity from the vicinity of the pith to near the bark were similar for all clones at each site; however, variations
in fiber length, microfibril angle, and specific gravity were more visible in northern Vietnam than in southern Vietnam, with
a significant effect of genetic factors. This difference may be attributable to winter, which is experienced in northern Vietnam
but not in southern Vietnam. For clone selection for plantation in the northern region, combining growth rate with wood properties
was recommended. On the other hand, for plantation in the southern region, clone selection depends mainly on the growth rate,
taking into consideration the specific gravity. 相似文献

Nine trees of Cryptomeria japonica from six elite tree clones with a broad range of heartwood colors were selected. The profiles of pit aspiration percentage (ASP) of earlywood and latewood from pith to bark for green and air-dry conditions were determined to study the relationship between heartwood color and pit aspiration. Confocal laser scanning microscopy (CLSM) observations showed that the ASP of earlywood was low in sapwood and high in heartwood in the green condition. Pit aspiration increased in intermediate wood when compared with sapwood. On the other hand, latewood pits did not aspirate during heartwood formation. Comparing the air-dry condition with the green condition, sapwood pits aspirated during drying in both earlywood and latewood; however, there was no significant difference in pit aspiration of heartwood. There was no significant difference between samples with red and black heartwoods for ASP. The difference in ASP between individual trees was larger than that by heartwood color. The general advantage of CLSM over light microscopy is that serial optical sections along the Z axis can be obtained for any moisture condition, without the need for thin sectioning or embedding. 相似文献

This study reported detailed clinical effects of bovine lactoferrin on 2 canine littermates (1 female and 1 male) with familial neutrophil dysfunction and an investigation of their genetic background. Clinical signs caused by severe upper respiratory bacterial infections were observed in these dogs. Oral administration of bovine lactoferrin for a long duration improved their clinical signs (severe uveitis in the female dog and coughing from pneumonia in the male dog). Their backcross dogs that have the same father didn't show clinical signs of bacterial infection. Neutrophil function tests revealed that the backcross dogs didn't have any disorders. It is likely that abnormal clinical signs are associated with neutrophil dysfunction in the colony, and the mother dog of these cases might be the genetic carrier of this dysfunction. 相似文献
