Modern sugarcane cultivars are highly polyploid with complex nuclear genomic genetic background, while their mitochondrion (mt) genomes much simpler, smaller and more manageable could provide useful phylogenetic information. In this study, the mt genome of a modern commercial cultivar A1 was sequenced via Illumina Hiseq XTen PacBio Sequel platform. The assembled annotated mitochondrial were com...
مقدمه: بیماری اکینوکوکوزیس یکی از مهم ترین بیماری های مشترک بین انسان و حیوان در بسیاری از مناطق دنیا از جمله ایران است که توسط مرحله لاروی کرم اکینوکوکوس گرانولوزوس ایجاد می گردد. این انگل از تنوع ژنتیکی بسیار بالایی برخوردار است و شامل کمپلکسی از ژنوتیپ (استرین) های مختلف است. معمولاً در مناطقی که بیماری آندمیک است، تنوع ژنتیکی نسبتاً زیادی در انگل از لحاظ بیولوژی وجود دارد. تحقیقات انجام شده د...
Hotspot archipelagoes provide exceptional models for the study of the evolutionary process, due to the effects of isolation and topographical diversity in inducing the formation of unique biotic assemblages. In this paper, we examine the evolutionary patterns exhibited by the jumping spider genus Havaika Prószyński, 2001 in the Polynesian islands of the Hawaiian and Marquesas chains. To date, s...
We report the complete nucleotide sequence of the Tetrahymena pyriformis mitochondrial genome and a comparison of its gene content and organization with that of Paramecium aurelia mtDNA. T. pyriformis mtDNA is a linear molecule of 47,172 bp (78.7 % A+T) excluding telomeric sequences (identical tandem repeats of 31 bp at each end of the genome). In addition to genes encoding the previously descr...
Most implementations of molecular clocks require resolved topologies. However, one of the Bayesian relaxed clock approaches accepts input topologies that include polytomies. We explored the effects of resolved and polytomous input topologies in a rate-heterogeneous sequence data set for Gnetum, a member of the seed plant lineage Gnetales. Gnetum has 10 species in South America, 1 in tropical We...
The disjunct distribution of forests in the Qinghai-Tibetan Plateau (QTP) and adjacent Helan Shan and Daqing Shan highlands provides an excellent model to examine vegetation shifts, glacial refugia and gene flow of key species in this complex landscape region in response to past climatic oscillations and human disturbance. In this study, we examined maternally inherited mitochondrial DNA (nad1 ...
The major contribution of this paper is the finding of a glycolytic source of ATP in the isolated postsynaptic density (PSD). The enzymes involved in the generation of ATP are glyceraldehyde-3-phosphate dehydrogenase (G3PD) and phosphoglycerate kinase (PGK). Lactate dehydrogenase (LDH) is available for the regeneration of NAD1, as well as aldolase for the regeneration of glyceraldehyde-3-phosph...
We expressed a cDNA encoding the Arabidopsis thaliana defense-related protein ELI3-2 in Escherichia coli to determine its biochemical function. Based on a protein database search, this protein was recently predicted to be a mannitol dehydrogenase [Williamson, J. D., Stoop, J. M. H., Massel, M. O., Conkling, M. A. & Pharr, D. M. (1995) Proc. Natl. Acad. Sci. USA 92, 7148–7152]. Studies on the su...
