Abstract:

The inner membrane of mitochondria harbors the complexes of the respiratory chain and the ATP synthase, which perform the key metabolic process oxidative phosphorylation. These complexes are composed of subunits from two different genetic origins: the majority of constituents is synthesized on cytosolic ribosomes and imported into mitochondria, but a handful of proteins, which represent core catalytic subunits, are encoded in the organellar DNA and translated on mitochondrial ribosomes. Using yeast as a model organism, I investigated the mitochondrial ribosomal tunnel exit, the region of the r

Abstract:

In the yeast Saccharomyces cerevisiae the production of respiratory competent mitochondria requires the activity of several hundred proteins, the vast majority of which are encoded by nuclear genes and imported into mitochondria. A subset of these nuclear gene products are required for the expression of individual mitochondrial genes. Expression of the mitochondrial gene cob, encoding cytochrome b, requires the activity of at least seven nuclear gene products, including CBP1, CBS1 and CBS2. CBP1 is required for the stability of cob transcripts, while CBS1 and CBS2 are required for translation

Maintaining energy organismal homeostasis under changing physiological and environmental conditions is vital, and requires constant adjustments of the energy metabolism.

碩士<br>國立海洋大學<br>食品科學系<br>88<br>Abstract The polymerase chain reaction (PCR) technology and sequence analysis were used to determine the amount of genetic variation in a 376 nucleotides region of the mitochondrial cytochrome b gene in fresh, frozen, cooked meat of puffer Takifugu rubripes and fresh, frozen and dried dressed fillets of puffer Takifugu oblongus. It was found that puffer Takifugu rubripes and T. oblongus had their unique genotypes. The range of sequence divergence between fresh, frozen and cooked meat of puffer Takifugu rubripes was not found and also between

Abstract:

The phylogeography of the common vole was well described for western Europe. Previously, five mtDNA lineages (based on mitochondrial DNA) have been described in Europe and they probably originated from five different refugia. However, the phylogeography of this rodent was not well studied in central and eastern Europe. In previous studies few samples from Poland, Slovakia, Hungary, Russia and Finland were used and it was recognized that in Poland, the Eastern lineage is present. The phylogeography of the field vole in Europe is well studied in the whole species range. Analyses based on mtDNA s

Abstract:

Analyses of the evolution and function of voltage-gated sodium channel proteins (Navs) have largely been limited to mutations from individual people with diagnosed neuromuscular disease. This project investigates the carboxyl-terminus of the Nav paralog (locus scn4aa 3’) that is preferentially expressed in electric organs of Neotropical weakly-electric fishes (Order Gymnotiformes). As a model system, I used the genus Gymnotus, a diverse clade of fishes that produce species-specific electric organ discharges (EODs). I clarified evolutionary relationships among Gymnotus species using mitochondri
