We sequenced partial mitochondrial 16S ribosomal DNA (16S rDNA) of 18 firefly species from Southwest of china. Combined with homologous sequences previously reported, phylogenetic trees including Japanese, Korean and chinese species were reconstructed by neighbor-joining, maximum parsimony and Bayesian methods. All reconstructions agree on most nodes of the trees. Monophyly of Lampyridae is not supported because Rhagophthalmus ohbai in Rhagophthalmidae is included within it. Lamprigera, a genus placed unreliably in Lampyrinae, shows a close relationship to Amydetinae. Monophyly of Luciolinae is not supported because Pristolycus sagulatus (Lampyrinae) is included within it. In the Luciolinae, monophyly of Curtos and Hotaria is well established, respectively, but both morphological and molecular data continue to indicate that Luciola is not monophyletic and its subdivision is indeed necessary. Within the Lampyrinae, both Pyrocoelia and Diaphanes are not monophyletic, but monophyly of Pyrocoelia + Diaphanes is well supported. Phylogeny of Diaphanes is discussed for the first time. Generic placement of a newly discovered species (Diaphanes pectinealis Li et Liang) sharing some characters of Pyrocoelia and Diaphanes challenges the delimitation of these two similar genera. With references to the firefly mating systems, we suggest that more emphases should be placed on those sexually selected characters such as antennal structure in taxonomy of Lampyridae.

chinese Science Bulletin 2002年第12期47卷 1003-1006页

作者： LIANG Chongrong & LIU CiquanKey laboratory of cellular & molecular evolution, kunming institute of zoology, chinese academy of sciences, kunming 650223, china Biology Department, Jinan University, Guangzhou 510630, china Key laboratory of cellular & molecular evolution Kunming Institute of Zoology Chinese Academy of Sciences Kunming China Biology Department Jinan University Guangzhou China

In order to understand the behavior of RNAs with large bulges in solution, molecular dynamics was performed on the RNA molecule in water with A6 bulge. The result of simulation showed that nonstacked conformation is the main conformation in large bulges, and the backbone of large bulge is of great conformational flexibility, but bulges-induced bends are relatively rigid. The fluctuation in bulge has little influence on the bend angle of RNAs.

关键词： RNA large bulge conformation bend angle.

There is strong relationship between melanocortin-1 receptor (MCIR) gene variants and human hair color and skin type. Based on a sequencing study of MC1R gene in 50 individuals from the Uygur, Tibetan, Wa and Dai ethnic populations, we discuss the occurrence of 7 mc1r variants consisting of 5 nonsynonymous sites (Val60Leu, Arg67Gln, Val92Met, Arg163Gln and Ala299Val) and 2 synonymous sites (C414T and A942G), among which C414T and Ala299Val were reported for the first time. Confirmation and analysis were the made of 122 individuals at three common point mutations (Val92Met, Arg163Gln, A942G) using PCR-SSCP. The frequency of Arg163Gln variant varies in the four ethnic populations, with percentage of 40%, 85.0%, 66. 2% and 72.7%, respectively, while those of Val92Met and A942G are roughly similar in these four populations. The different environments, migration and admixture of various ethnic groups in china might have impact on the observed frequency of Arg163Gln.

Seven sets of protein target sites, which occur in several gene promoters, have been analyzed. The results suggest that there is a possible mode of specific recognition of double-helical nucleic acids by proteins. This recognition mode is related to a special topological property of double-helical DNA, which is termed base spatial pattern (BSP) of DNA segment. BSP is the spatial topological property determined only by the spatial arrangement of the bases on double-helical DNA segment.

关键词： protein nucleic acids recognition base spatial pattern (BSP) target sites.

Two multigene superfamilies, named V1R and V2R, encoding seven-transmembrane-domain G-protein coupled receptors (GPCRs) have been identified as pheromone receptors in mammals. Three V2R gene families have been described in mouse and rat. Here we screened the updated mouse genome se- quence database and finally retrieved 63 putative functional V2R genes including three newly identified genes which formed a new additional family. We described the genomic organization of these genes and also characterized the conservation of mouse V2R protein sequences. These genomic and se- quence information we described are useful as part of the evidence to speculate the functional domain of V2Rs and should give aid to the functionality study in the future.

大量实验研究显示 ,真核基因的许多内含子具有调控转录的功能 ,但是对此问题尚缺乏全面的研究 .观察一些酵母基因的转录频率与基因的内含子序列后 ,发现一个值得注意的现象 :转录频率高的基因内含子序列一般都比较长 ,而转录频率低的基因内含子一般都比较短 .这提示高效转录基因的较长内含子中可能含有某些增强基因转录的特征性结构 .于是选取两组酵母基因的内含子进行详细研究 ,第一组的基因具有较高的转录频率 (>30 ) ,第二组的基因转录频率较低 (≤ 10 ) .对寡核苷酸 (主要是四核苷酸、五核苷酸 )的出现频率进行统计比较分析 ,探测到一批寡核苷酸 ,它们在第一组内含子中出现的频率显著高于在第二组内含子中出现的频率 ,同时也显著高于与第一组内含子相邻的外显子中的出现频率 .其中一些寡核苷酸与实验研究得到的转录调控元件相同 .从这批寡核苷酸在内含子和外显子序列中的分布看。

基因的复制、融合以及基因的水平转移是许多蛋白质包括氨酰 tRNA合成酶 (aminoacyl tRNAsynthetase ,AARS)进化过程中的常见事件。然而作者研究的结果显示 ,苯丙氨酰 tRNA合成酶 (phenylalanyl tRNAsynthetase,PheRS)的进化主要表现为一些结构域的丢失 ;并且这种结构域的丢失不影响PheRS的功能或活性。通常在生物从细菌到真核生物的进化过程中 ,其基因组的大小和基因的数目都有所增加 ,然而有趣的是 ,真核生物中PheRS的结构域类型和数目都明显少于细菌的PheRS。PheRS通过结构域的丢失而进化的现象 ,似乎与某些AARS功能由多重专一性向单一专一性的演化有着“异曲同工”之妙。
