background although certain hbv mutations are known to affect the expression of hepatitis e antigen, their association with hbv viral level or clinical outcomes is less clear. objectives we evaluated associations between different mutations in the basal core promoter (bcp) and pre-core (pc) regions of hbv genome and subsequent changes in hbv viral dna level over seven years in a population of u...
We present a genome assembly from an individual male Hedya salicella (the White-backed Marble; Arthropoda; Insecta; Lepidoptera; Tortricidae). The sequence is 742.3 megabases in span. Most of the scaffolded into 25 chromosomal pseudomolecules, including Z sex chromosome. mitochondrial has also been assembled and 16.3 kilobases length. Gene annotation this on Ense...
The male-specific regions of primate Y-chromosomes (MSY) are enriched for multi-copy genes highly expressed in the testis. These genes are located in large repetitive sequences arranged as palindromes, inverted-, and tandem repeats termed amplicons. In humans, these genes have critical roles in male fertility and are essential for the production of sperm. The structure of human and chimpanzee a...
This paper presents a first genetic linkage map of the goat genome. Primers derived from the flanking sequences of 612 bovine, ovine and goat microsatellite markers were gathered and tested for amplification with goat DNA under standardized PCR conditions. This screen made it possible to choose a set of 55 polymorphic markers that can be used in the three species and to define a panel of 223 mi...
A primary male autosomal linkage map of the domestic horse (Equus caballus) has been developed by segregation analysis of 140 genetic markers within eight half-sib families. The family material comprised four Standardbred trotters and four Icelandic horses, with a total of 263 offspring. The marker set included 121 microsatellite markers, eight protein polymorphisms, five RFLPs, three blood gro...
Male germ cell differentiation is a highly regulated multistep process initiated by the commitment of progenitor cells into meiosis and characterized by major chromatin reorganizations in haploid spermatids. We report here that a single member of the double bromodomain BET factors, Brdt, is a master regulator of both meiotic divisions and post-meiotic genome repackaging. Upon its activation at ...
Mitochondria are responsible for providing energy currency to life processes in the molecular form of ATP and are therefore typically referred to as the power factories of cells. Plant mitochondria are also relevant to the common phenomenon of cytoplasmic male sterility, which is agronomically important in various crop species. Cytoplasmic male sterility (CMS) is a complex trait that may be inf...
A male linkage map of the cattle (Bos taurus) genome was constructed using nine large half-sib families. The map consists of 269 loci, of which 249 are microsatellites and 20 are structural genes. Among the 249 microsatellites, 140 are markers selected from other maps and 98 are new assignments. Chromosome assignment were established for 35 new markers by somatic cell hybrid analysis, of which ...
