One of the most invasive species worldwide, Solenopsis invicta Buren, has been described in China since 2003. Recent studies have suggested that China populations are the result of introductions from the USA; however, detailed molecular studies need to be performed in order to understand the expansion and potential multiple introductions from other countries into China. As there were populations of red imported fire ant, S. invicta in different areas and with different methods of introduction, mitochondrial cytochrome oxidase Ⅰ gene was used as a marker from 12 populations in four cities in Fujian Province, China, to determine the relationship of invasion among these populations. The three most common haplotypes previously describe in invasive populations of S. invicta： H5, H22 and H36, were found in Fujian. However, frequencies in each city were different. For instance, three populations from Longyan city which invaded with waste plastics, shared haplotype H5. Populations from Xiamen city and Jinjiang city which dispersed with nursery stock, sward and scrap leather, shared haplotype H22. The population from Nanyan village of Xinluo district, Longyan city, bore haplotype H36. mitochondrial data reveals that the invasion history of S. invicta in Fujian Province is complex, including multiple invasions probably from other provinces within China. Security measures to prevent S. invicta spreading within China are as important as from overseas.

Background Leigh syndrome is an inherited neurodegenerative disease that emerges in infancy and childhood and presents with a clinically heterogeneous variety of neuromuscular and non-neuromuscular disorders. It can result from the inheritance of mutations in either nuclear or mitochondrial DNA. In the current study, we performed a retrospective study in 65 patients in order to investigate the clinical and genetic characteristics of Leigh syndrome in Chinese patients. Methods Sixty-five unrelated cases （35 men and 30 women） who were hospitalized in the past 12 years were reviewed. Diagnosis was based on both the clinical presentation and the characteristic neuropathologic findings of bilateral symmetric necrotizing lesions in the basal ganglia and brain stem as detected using cranial computed tomography （CT） scan or magnetic resonance imaging （MRI）. The differential diagnosis of organic acidurias and fatty acid IS-oxidation defects were performed. Specific point mutations and deletions in mitochondrial DNA （T8993G, T8993C, T9176C, A8344G, A3243G） were screened by PCR-restriction analysis and Southern blot. The SURF1 gene was sequenced. Skeletal muscle biopsies were performed in 17 （26.2%） of the patients. The diagnosis was confirmed by autopsy in 6 （9.2%） patients. Results The patients had various forms of metabolic encephalomyopathy. Filly-nine （90.8%） of the patients had the typical neuroradiological features of Leigh syndrome, including symmetrical necrotizing lesions scattered within the basal ganglia, thalamus and brain stem. Twenty （30.8%） patients were confirmed by genetic, biochemical analysis and autopsy. Specific point mutations in mitochondrial DNA were found in 5 cases （7.7%）. Of these, the A8344G mutation was detected in 2 patients. The T8993G T8993C, and A3243G point mutations were identified in 3 other patients, respectively. SURF1 mutations associated with cytochrome c oxidase deficiency were identified in 8 （12.3%） families by DNA sequencing. A

Entomotaxonomia 2014年第1期36卷 23-35页

作者：付文博周善义陈志林陈媛梁立为广西师范大学生命科学学院广西桂林541004 重庆师范大学生命科学学院重庆400047 珍稀濒危动植物生态与环境保护教育部重点实验室广西桂林541004

Partial eytochrome oxidase subunits I （COI） and II （COII）, and cytochrome b （Cyt b） genes of thirteen species of the ant genus Formica were sequenced for molecular phylogenetic studies. The sequences were as follows： COI fragment, 657 bp; COl ＋ COIl fragments, approximately 900 bp, including the termination codon at the end of COI and the initiator codon at the beginning of COIl; and the Cyt b fragment, 777 bp. Results show that these three mitoehondrial genetic markers are similar in base composition. The contents of A ＋ T were 73.8% （COl） and 79.2% （COII）--higher than those of G ＋ C, which were 20.8% （COIl） and 26.2% （COI）, and strongly AT-biased. The highest A ＋ T contents were 89.9% （COI） and 93.7% （COII） on the third codon, whereas the lowest G content was 0.2% （COII） and 1.2% （Cyt b）. Molecular phylogenetic trees based on these mitoehondrial genes were reconstructed. Cataglyphis aenescens in the subfamily Formicinae was used as the outgroup, and Diacamma rugosum of the subfamily Ponerinae was used as an additional, distantly-related outgroup. Phylogenetic analysis showed that the differences among the species in the in-group were small, with genetic distance values less than 0.1. The greatest genetic distance was between E beijingensis and F. cunicularia. The results are in accord with those based on morphological features.
