Genetic Diversity and Population Structure in the Heavily Exploited Korean Rockfish,Sebastes schlegeli,in Korea

The Korean rockfish, Sebastes schlegeli, is a valuable and intensively exploited species in Korea. We discuss the genetic diversity and genetic structure of four Korean rockfish populations using eight microsatellite loci. In total, 161 different alleles from 138 individuals were observed. Average allele number per locus ranged from 2.5 to 23 and allelic richness varied from 13.38 to 14.63 within a population. Despite a long history of stocking practices, we found very high levels of polymorphism (mean heterozygosity = 0.810), which is comparable to other congeneric species. No significant difference in genetic diversity and molecular genetic variance (F_ST and R_ST) was observed among four local samples (P > 0.1). Little indication of contemporary inbreeding (F_IS= 0.051) or population structure (K = 1) was detected. This absence of differentiation may reflect high levels of gene flow along the coast of Korea. Our study demonstrates that rockfish in Korea should be managed as a single unit. Currently, the species does not appear to be genetically threatened, but the potential for a rapid loss of genetic diversity remains. This information on the genetic characteristics of Korean rockfish populations has important implications for fisheries management and conservation efforts, and will aid in the sustainable exploitation of the fishing resources and the preservation of biodiversity.  相似文献   

Systemic accumulation of novel proteins in the apoplast of the leaves of potato plants following root invasion by the cyst-nematode Globodera rostochiensis     

Kim E. Hammond-Kosack  Howard J. Atkinson  Dianna J. Bowles   《Physiological and Molecular Plant Pathology》1989,35(6)

Systemic changes in gene expression have been analysed in potato plants following root infection with the cyst nematode Globodera rostochiensis. Root invasion by the pathogen induced major changes to occur in the composition of proteins extracted in intercellular fluid from the leaf apoplastic space. The changes involved the disappearance of innate leaf proteins and the accumulation of novel gene products. Analysis by SDS-PAGE indicated that the leaf polypeptides induced on nematode invasion are not cultivar or nematode pathotype-specific. Aspirin treatment of leaves induced a similar pattern to that induced systemically by nematodes, but several gene products were specific for the latter method of induction. In particular, two abundant [¹²⁵I]-Con A binding polypeptides of high M_r accumulated in intercellular fluid only on aspirin treatment. The results are discussed in the context of the role of the extracellular leaf proteins and their modulation by systemic signals.  相似文献   

Reticuloendotheliosis virus integration in the fowl poxvirus genome: not a recent event   总被引：3，自引：0，他引：3  

Kim TJ  Tripathy DN 《Avian diseases》2001,45(3):663-669

Integration of reticuloendotheliosis virus (REV) into the genome of fowl poxvirus (FPV) has been reported recently. With a view to determine whether this event had occurred in the past, we screened by polymerase chain reaction (PCR) for the presence of REV provirus in the DNAs of nine avian poxviruses, some of which had been lyophilized 50 yr ago. For REV, 5' long terminal repeat (LTR) and REV envelope sequences were amplified, whereas for FPV, the major envelope antigen gene and the region flanking REV sequences were amplified. In six of seven FPV strains examined, the specific PCR amplicons were obtained for both REV provirus and FPV sequences. One isolate in which presence of REV 5' LTR and envelope was not detected by PCR, a LTR remnant was detected by Southern hybridization. Interestingly, no REV sequence was detected in either canary poxvirus or pigeon poxvirus genome. These observations indicate that REV integration in the FPV genome is not a recent phenomenon but probably occurred prior to 1949.  相似文献
