利用PCR-SSCP结合DNA测序方法,对贵妃鸡、怀乡鸡及二者的杂交F1代共计360个个体EX-FABP基因遗传特征及品种差异进行研究,发现2773T>C,2867 C>T和2913 G>A三个位点在贵妃鸡中表现为单态,在怀乡鸡和杂交F1群体中表现为多态,这3个位点有望作为贵妃鸡、怀乡鸡乃致其他品种鸡种质资源鉴定的参考依据。对比分析3个群体胸肌肌内脂肪含量(IMF)表明,怀乡鸡和杂交鸡母鸡的IMF显著高于贵妃鸡;而3个群体公鸡间的IMF差异不显著;除贵妃鸡外,同一品种内公鸡的IMF均小于母鸡(P<0.05)。多态位点与鸡胸肌肌内脂肪含量的相关性分析结果表明,在2773位点,TC基因型个体的IMF值大于TT基因型;在2913位点,AA基因型个体的IMF值大于GG基因型,但没有达到显著水平(P>0.05)。  相似文献

The extruded protoplasm from the coenocytic green alga, Bryopsis hypnoides Lamouroux, was able to reform a cell wall and develop further into a mature alga in seawater. In this paper, the influence of albumen on the ability of aggregation and on the photosynthesis of protoplasm was examined. Results show that the protoplasm of B. hypnoides could aggregate in either albumen or chicken egg, which is similar to that in seawater. However unlike in seawater, the aggregation from B. hypnoides in albumen and chicken egg failed to develop into a mature individual. Interestingly, the protoplasm of B. hypnoides could maintain its photosynthetic O2 evolution in albumen and chicken egg, while the time in chicken egg was longer than that in albumen.  相似文献

Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was applied in the detection of the end point temperature (EPT) of thermal denatured protein in fish and meat in this study. It was also used in studying the thermal denatured temperature range of proteins in salmon and chicken meat. The results show that the temperature ranges of denatured proteins were from 65 ℃ to 75 ℃ , and these temperature ranges were influenced by the processing methods. Through SDS-PAGE, the features of repeated he...  相似文献

The present work is the first report of the biochemical characterization of the venom from nematocysts of the jellyfish Rhopilema esculentum Kishinouye. The nematocysts were isolated by autolysis and centrifugation and separated by flow cytometry. Four types of nematocysts were identified: mastigophores, euryteles, and atrichous and holotrichous isorhiza. SDS-PAGE and amino acid analyses demonstrated that most of the proteins in the nematocyst extract were between 10 kDa and 40 kDa, and that glutamic acid was the main amino acid. A hemolytic activity assay showed that the activity of the nematocyst venom (RNV) was strongest in Tris-HCl buffer (50 mmol/L, pH 7.8, 5% glycerol, 0.5 mmol/L EDTA, 0.1 mol/L NaCl). The hemolytic activity was related to protein concentration and the HU50 against chicken erythrocytes was 0.91 μg/mL.  相似文献
