Fenneropaeneus chinensis is an important species in marine fishery resources and aquaculture in china. A genetic linkage map is essential for improving the efficiency of its breeding by marker-as- sisted selection and identifying commercially important genes. Linkage maps of F. chinensis were constructed with an F2 mapping population (110 progenies) using amplified fragment length polymor- phic (AFLP) marker in this study. Fifty-five AFLP primer combinations produced 532 AFLP markers fitting for map strategy in mapping family. The markers with 3:1 segregating ratios were analyzed using F2 intercross model for the common linkage map, while the markers with 1:1 ratio were analyzed using the pseudo-testcross strategy. The maps of male, female and common were constructed. The female map included 103 markers that formed 28 linkage groups, covering a total length of 1090 cM. All mark- ers were linked with the linkage groups. Segregation distortion was observed for 6 of 103 markers in the female map. The average distance between markers was 14.53 cM and ranged from 4.4 to 24.8 cM. The male map included 144 markers that formed 35 linkage groups. Ten markers remained unlinked in male map. Segregation distortion was observed for 7 of 144 markers in the male map. The total dis- tance of male map covered 1617 cM. The average distance between markers was 16.36 cM. The male map was 32.6% longer than the female map, which may reflect sex-specific recombination rates in chinese shrimp. The common map was composed of 216 markers, including in 44 linkage groups covering a total distance of 1772.1 cM. Two markers remained unlinked. No distorted markers of 216 markers were shown in the common map. The distance between markers was 10.42 cM. An average estimated genome size for the chinese shrimp was 2420 cM, which was consistent with the relative size of the Penaeid genome. The distribution of AFLP markers was relatively even in chromosomes of Chi- nese shrimp maps. The linkage analysis

Acta Oceanologica Sinica 2011年第1期30卷 78-86页

An analysis of a selection experiment was used to assess the impact of various animal model struc- tures on REML estimates of variance components. The analyses were carried out based on 162 d body mass （BM） of 1 287 animals from 21 paternal half-sib groups of Fenneropenaeus chinensis. Estimated breeding values （EBV） of BM of all individuals were estimated using eight statistical models （A, AB, ABC, ABDC, ABMFC, ABMDC, ABFDC and ABMFDC） and BLUP （best linear unbiased prediction）. These models were designed involving factors such as sex, spawn date as fixed effects, maternal genetic effects, full-sib family effects as random effects, mean BM of families at tagging and age at recording （covariate）. The results demonstrate the importance of correct interpretation of effects in the data set, particularly those that can influence resemblance between relatives. The data structure and the particular model that was applied markedly influenced the magnitude of variance component estimates. Models based on few effects obtained upward biased estimates of additive genetic variance. The accuracy of genetic parameters and breeding value es- timated by ABFDC model was higher than other models. The results imply that additive genetic direct value, full-sib family effects, and covariance effects besides sex and spawn date as fixed effects were very important for estimating genetic parameters and breeding value of body mass. This model had a heritability estimate of 162 d BM of 0.44. The comparison of the efficiency of selection based on breeding values or phenotypic value revealed great difference： average breeding value of the best 24 families selected by the 162 d BM breeding value and phenotype were 0.577 g and 0.366 g, respectively, representing a 36.57% higher efficiency in the former. In conclusion, selection based on breeding value was more effective than selection based on phenotypic value. Our results indicate that effects influencing the magnitude of estimates should be tak

Estimates of genetic and phenotypic parameters for weight and length in Paralichthys olivaceus(Temminck et Schlegel)

引用

Acta Oceanologica Sinica 2011年第6期30卷 58-64页

作者： tian Yongsheng XU tianjun LIANG You CHEN Songlin Key Laboratory for Sustainable Utilization of Marine fisheries Resources Ministry of Agriculture Yellow Sea Fisheries Research Institute Chinese Academy of Fishery Sciences Qingdao 266071 China Laboratory for Marine Living Resources and Molecular Engineering College of Marine ScienceZhejiang Ocean University Zhoushan 316000 China

The complete diallel cross design was employed to estimate the genetic parameters of the growth of Japanese flounder （Paralichthys olivaceus）. A total of 60 full-sib families were cultivated and two growth-related traits, body weight （BW） and body length （BL）, were examined at average 2, 3 and 8 months of age respectively, with 1 800 individuals measured in each age group （30 per family）. Based on the additive-dominance-maternal-effect genetic analysis model, the restricted maximum likelihood approach was used to estimate various （co）variance components. The results showed that narrow-sense heritability estimates of BW and BL were respectively： 0.29 ± 0.01 and 0.22 ± 0.02 at 2 months of age, 0.32 ± 0.02 and 0.30 ± 0.04 at 3 months of age, 0.48 ± 0.04 and 0.40 ± 0.05 at 8 months of age; broad-sense heritability estimates were respectively： 0.44 ± 0.02 and 0.54 ± 0.04 at 2 months of age, 0.35 ± 0.01 and 0.36 ± 0.03 at 3 months of age, 0.49 ± 0.03 and 0.45 ± 0.04. All heritabilities were statistically significant （P 0.05）. Additive genetic correlations between BW and BL at 2, 3 and 8 months of age were consistently positive and highly significant （P 0.01）： 0.93 ± 0.02, 0.95 ± 0.03 and 0.92 ± 0.03 respectively. Maternal effect was significant （P 0.05） only at 2 months of age, and was not detected at 3 and 8 months of age. According to the heritability estimates, the mass selection strategy should be efficient for the breeding of Japanese flounder.

TdT mediated dUTP biotin nick end labeling (TUNEL) is a sensitive and valid method for detecting DNA cleavage in programmed cell death (PCD). Using this method, DNA cleavage was observed in Laminaria japonica sporophytic tissues, which were infected with alginic acid decomposing bacterium. It was found that DNA cleavage occurred 5 min after the infection, the fragments with 3′ OH groups of cleaved nuclear DNA increased with time of infection and spread from the infection site. Although no typical DNA ladder (200 bp/180 bp) was detected by routine agarose gel electrophoresis, the cleavage of nuclear DNA fragments of 97～48.5 kb could be detected by pulsed field gel electrophoresis (PFGE). By using CaspGLOW TM fluorescein active caspase 3 staining method, caspase 3 activity has been detected in response to the infection of alginic acid decomposing bacterium. Our results are similar to the observations in hypersensitive response (HR) of higher plant, suggesting that the rapid cell death of L. japonica infected by alginic acid decomposing bacterium might be involved in PCD, and indicating that the occurrence of PCD is an active defense process against the pathogen's infection.

The C-banding pattern and nucleolar organizer regions of the metaphase chromosomes of Cynoglossus semilaevis are reported. The interstitial regions in all chromosomes including the pair of sex chromosomes had positive C-bands, and the 6th and 12th pairs of chromosomes were entirely stained in most cases. Some chromosomes such as the 1st, 2nd, 7th, 8th, 9th and 10th pairs showed C-bands at centromeric or distal ends. The C-banding heretochromatin occupies 30.03% of the total chromosome surface in C. semilaevis, which is similar to that of amphibians such as Mixophyes fasciolatus (30. 2% ) and M. schevilli (20. 7% ), but is rather lower than that of cephalochordate Branchiostoma belcheri (54. 3 % ). Silver staining revealed a single pair of nucleolar organizer regions ( NORs) located in the telomeric regions of Chromosome 2. The association of NORs with heterochromatin observed in vertebrates also occurs in C. semilaevis as the telomeric regions of Chromosome 2 are always stained positively with C-banding.

一个包括42个全同胞家系的中国对虾选育群体,荧光标记后每个家系各取40尾健康个体混养,自然发病并确认感染白斑综合征病毒(white spot-syndrome virus,W SSV)。发病1周后将所有个体取出,统计各家系的存活率,并对活体利用巢式聚合酶链式反应(polymerasechain reaction,PCR)进行W SSV检测。对存活率进行分析,结果显示:4个家系的存活率在60%以上,7个家系的存活率在20%以下;存活率与第一次扩增阳性率、第二次扩增阳性率呈不显著负相关。第一次扩增阳性率与第二次扩增阳性率呈极显著正相关。结合两次扩增的阳性率分析得出:青岛野生群体内自交产生的一个家系和韩国群体养殖家系与乳山野生群体杂交产生的一个家系在抗病力上显著优于其它家系;经独立样本t检验表明,群体间交配组合的存活率差异不显著,因此家系选育可能是进行抗W SSV品种选育的重要途径。多重比较结果发现:韩国群体养殖家系(♂)与乳山野生群体(♀)杂交后代的存活率(56.20%±8.75%)显著高于韩国群体养殖家系自交后代(22.50%±2.50%)(P26.95)与其反交后代(3.85)差异显著。

利用微卫星技术对中国对虾人工选育群体第1代和第6代群体的遗传多样性进行了分析。对10个微卫星位点进行了扩增,共产生74个等位基因,每个位点产生的等位基因数从3到13不等。在两个群体中,所观察到的等位基因数都比有效等位基因数多。多态信息含量PIC值0.5567～0.8877,说明这10个微卫星位点在中国对虾中具有较高的信息含量。两个群体的平均杂合度分别为0.6400(CP1)、0.6300(CP6),并通过计算基因型的P值,确定了对Hardy Weinberg平衡的偏离情况。对Fis值的计算表明两个群体内共有5个微卫星位点存在杂合度观察值过剩的现象。两个群体的Shannon多样性指数分别为1.6830、1.7382,整个选育群体(两个群体作为一个群体)的遗传多样性指数为1.7742。从遗传多样性所占的比例来看,96.415%的遗传变异是来自群体内,只有3.585%的遗传变异是来自群体间。两个群体间的相似性系数高达0.9187,彼此间的遗传距离仅为0.0848,体现出人工选育群体的遗传分化程度较低。结果均说明第6代群体还有较大的选育潜力,可以继续保持遗传效应,最终保证选种育种工作的成功。

卤虫是虾、蟹苗种培育的关键动物性饵料,查清其能否携带白斑综合征病毒,对培育健康苗种至关重要。2002年7月至10月,自盐田中取野生卤虫,经暂养后选20尾抱卵雌虫,每尾置1个烧杯中,投喂单胞藻,产卵后取出亲体;20d后,每个烧杯中取5尾子一代个体,利用巢式体外DNA扩增技术对亲体和子一代成体进行WSSV病毒检测。检测结果显示:卤虫中可扩增出特异性的、与引物设计吻合的DNA片段;DNA测序分析表明,扩增片段的DNA序列与白斑综合征病毒序列一致;野生卤虫携带白斑综合征病毒的阳性率为58%,实验条件下野生卤虫后代的阳性率为43%;同一家系中,亲代与子代携带病毒的情况不完全一致,不能确定白斑综合征病毒可否通过繁殖,在卤虫世代间进行垂直传播。研究结果表明:卤虫很可能是白斑综合征病毒的携带者,苗种培育和养殖期间投喂卤虫可能造成虾、蟹感染白斑综合征病毒,卤虫检疫是培育健康苗种的关键措施。
