Bypass Mechanism

Abstract The induction of mitochondrial function is dependent upon both nuclearly encoded and mitochondrially encoded gene products. To understand nuclear-mitochondrial interactions, we must first understand gene-specific interactions. The accumulation of mitochondrial cytochrome b (COB) RNA is dependent upon Cbp1p, encoded by the nuclear gene CBP1. Thus, respiration is dependent upon Cbp1p. In this study, suppressors of temperature-sensitive cbp1 (cbp1ts) strains were selected for restoration of respiratory capability at the restrictive temperature Ts+). One nuclearly encoded suppressor, extragenic to CBP1, is recessive with respect to the wild-type suppressor allele and is unlinked to other known genetic loci whose gene products are necessary for expression of COB mRNA. The suppressor, called soc1 for Suppressor of cbp1, suppresses several other cbp1ts alleles but does not operate via a bypass mechanism. Molecular analyses indicate that soc1 allows the steady-state level of COB mRNA to increase at high temperature but has little or no effect on the levels of COB pre-mRNA. These data have led us to propose that the product of the nuclear gene SOC1 is required for normal turnover of COB mRNA.

Pcr Products

The identification of fish species in food products is problematic because morphological features of the fish are partially or completely lost during processing. It is important to determine fish origin because of the increasing international seafood trade and because European Community Regulation 104/2000 requires that the products be labeled correctly. Sequence analysis of PCR products from a conserved region of the cytochrome b gene was used to identity fish species belonging to the families Gadidae and Merluccidae in 18 different processed fish products. This method allowed the identification of fish species in all samples. Fish in all of the examined products belonged to these two families, with the exception of one sample of smoked baccalà (salt cod), which was not included in the Gadidae cluster.

Cyt B Gene

The mitochondrial cytochrome b (cyt-b) gene as a phylogenetic marker of lais fish Kryptopterus schilbeides from Kampar River in Riau has been studied. This is a prelimininary research on the utility of cyt-b gene as a molecular marker to obtain species diversity and phylogenetic relationship among Kryptopterus fishes from Kampar River. The primers of L14841 and H15149 were used to amplify the cyt-b gene. The results showed that K. schilbeides has isoleusine at site-81 and metionine at site-114; K. schilbeides from Kampar River and K. schilbeides from GenBank form a phylogeny cluster at 45% value.
