Genome size estimates and their evolution can be useful for studying the phylogenetic relationships and taxonomy of a particular group. In the present study, the genome sizes of the three species that comprise the Mycetophylax genus were estimated by flow cytometry (FCM). There was little variation in genome size among them. The mean haploid genome size value of male and female individuals of Mycetophylax morschi was 312.96 Mbp (0.32 pg) and that of Mycetophylax conformis and Mycetophylax simplex females were 312.96 Mbp (0.32 pg) and 381.42 Mbp (0.39 pg), respectively. At first glance, this variation could be related with the heterochromatin content. Our results, together with other previous reports, have contributed to our knowledge about Attini genome size and will be useful to improve the understanding of the evolution of this tribe. It will help select potential model species in Attini for future genomic and sequencing projects. 相似文献

We report the characterization of novel nucleus specific autoantibodies in the serum of a patient with systemic lupus erythematosus. Immunofluorescent staining of cycling cells and absorption experiments localized the antigen to the nuclear envelope. Two-dimensional gel electrophoretic analysis of immunoprecipitated nuclear proteins show the antigen to be an acidic polypeptide (IP approximately 5.4) of 68 kDa molecular mass. It has been identified as lamin B, one of the three major nuclear envelope polypeptides of mammalian cells. Antibodies shown to be polyclonal immunoglobulin Gs, were directed against determinant(s) of the protein that have apparently been conserved during evolution. They do not appear to be related to other autoantibodies present in the serum (anti-DNA and anti-platelet). The nuclear specificity shown by these antibodies further demonstrates the antigenicity of proteins related to intermediate filament proteins in patients with autoimmune disorders. 相似文献
