The yeast Ty1 LTR retrotransposon replicates by reverse transcription and integration; the process shows many similarities to the retroviral life cycle. However, we show that plus strand strong-stop DNA transfer in yeast Ty1 elements differs from the analogous retroviral process. By analysis of the native structure of the Ty1 primer binding site and by a series of manipulations of this region a...
With the easy acquisition of sequence data, it is now possible to obtain and align whole genomes across multiple related species or populations. In this work, I assess the performance of a statistical method to reconstruct the whole distribution of phylogenetic trees along the genome, estimate the proportion of the genome for which a given clade is true, and infer a concordance tree that summar...
The Pacific chinook salmon occurs as both white- and red-fleshed populations, with the flesh color type (red or white) seemingly under strong genetic influence. Previously published data on crosses between red- and white-fleshed individuals cannot be reconciled with a simple Mendelian two-locus, two-allele model, pointing to either a more complex inheritance pattern or the existence of gene int...
As already demonstrated in greenhouse trials, outcrossing of transgenic plants can be drastically reduced via transgene integration into the plastid. We verified this result in the field with Petunia, for which the highest paternal leakage has been observed. The variety white 115 (W115) served as recipient and Pink Wave (PW) and the transplastomic variant PW T16, encoding the uidA reporter gene...
Mendelian crosses were used to analyze the patterns of inheritance of Cry-toxin resistance in two colonies of Culex quinquefasciatus Say larvae resistant to bacterial toxins produced by Bacillus thuringiensis subsp. israelensis de Barjac. Resistance levels exceeded 1000-fold at 95% lethal concentration of the CryllAa-resistant colony (Cq11A). F1 offspring of reciprocal crosses to a susceptible ...
It is generally assumed that mitochondrial genomes are uniparentally transmitted, homoplasmic and nonrecombining. However, these assumptions draw largely from early studies on animal mitochondrial DNA (mtDNA). In this review, we show that plants, animals and fungi are all characterized by episodes of biparental inheritance, recombination among genetically distinct partners, and selfish elements...
Two sibs who sustained severe hypoglycaemia in the neonatal period are reported. In spite of treatment with frequent feeds intravenous glucose, glucagon, hydrocortisone, and diazoxide, hypoglycaemia persisted, and both infants eventually required subtotal pancreatectomy. Tests for leucine toleranct were normal though the second case showed some protein sensitivity. Histological and immunohistoc...
For several years Y-chromosomal microsatellites (short tandem repeats, STRs) have been well established in forensic practice. In this context, the genetic characteristics of the Y chromosome (i.e. its paternal inheritance and lack of recombination) render STRs particularly powerful. However, genetic differences between male populations appear to be larger for Y-STRs than for autosomal STRs, a f...
Hereditary hemochromatosis has an autosomal recessive inheritance pattern. The homozygous diseased state occurs in 50 of 10,000 and the heterozygous non-diseased carrier state in 1000 of 10,000 caucasians.3 The typical case has two unaffected heterozygote carrier parents. However, HH can occur in consecutive generations owing to the chance mating between an as-yet-undetected homozygote and a he...
