“…Except one SNP that results in an amino acid change from Serine to Glycine in the ND4 gene (position 12689), all SNPs were silent mutations. The mutations in the control region are located outside of the promoter region (Lan et al 2015 [1], L'Abbee et al 1991 [53] for exact positions of this region).…”

Mitochondria are essential components of eukaryotes as they are involved in several organismic key processes such as energy production, apoptosis and cell growth. Despite their importance for the metabolism and physiology of all eukaryotic organisms, the impact of mitochondrial haplotype variation has only been studied for very few species. In this study we sequenced the mitochondrial genome of 180 individuals from two different strains of laying hens. The resulting haplotypes were combined with performance data such as body weight, feed intake and phosphorus utilization to assess their influence on the hens in five different life stages. After detecting a surprisingly low level of genetic diversity, we investigated the nuclear genetic background to estimate whether the low mitochondrial diversity is representative for the whole genetic background of the strains. Our results highlight the need for more in-depth investigation of the genetic compositions and mito-nuclear interaction in individuals to elucidate the basis of phenotypic performance differences. In addition, we raise the question of how the lack of mitochondrial variation developed, since the mitochondrial genome represents genetic information usually not considered in breeding approaches.

“…Έτσι στα θηλαστικά βρίσκονται σε απόσταση 150 βάσεων και λειτουργούν κυρίως μονόδρομα (Clayton 1992). Στο αμφίβιο Xenopus λειτουργούν και προς τις δύο κατευθύνσεις (Bogenhagen and Yoza 1986), ενώ στα πτηνά έχει εντοπιστεί ένας μόνο υποκινητής, που δρα και προς τις δύο κατευθύνσεις (L'Abbé et al 1991).…”

We present the first comprehensive analysis of the crocodilian control region. We have analyzed sequences from all three families of Crocodylia (Crocodylidae, Gavialidae, Alligatoridae), incorporating all genera except Paleosuchus and Melanosuchus. Within the control region of other vertebrates, several sequence motifs and their order appear to be conserved. Herein, we compare aligned crocodilian D-loop sequences to homologous sequences from other vertebrates ranging from fish to birds. Among other findings, we have discovered that while domain I tends to be shorter than the same region in mammals and birds, it contains sequences similar in structure to both the goose-hairpin and termination associated sequences (TAS). Domain II is highly conservative with regard to size among the taxa examined and contains several of the conserved sequence boxes characterized in other vertebrates. Domain III contains several interesting sequence motifs including tandemly repeated sequences, a long poly-A region in the Crocodylidae, and possible bidirection promoter sequences.
