Rumex acetosa Y chromosomes: constitutive or facultative heterochromatin?
Condensed Y chromosomes in Rumex acetosa L. root-tip nuclei were studied using 5-azaC treatment and immunohistochemical detection of methylated histones. Although Y chromosomes were decondensed within root meristem in vivo, they became condensed and heteropycnotic in roots cultured in vitro. 5-azacytidine (5-azaC) treatment of cultured roots caused transitional dispersion of their Y chromosome ...
متن کاملDHPLC Applications: Finding DNA Variation on the Y Chromosome
Denaturing High-Performance Liquid Chromatography (DHPLC) is a recently developed technique forthe detection of single nucleotide polymorphisms (SNPs) and mutations. It involves the comparisonbetween two or more DNAs as a mixture of denatured and reannealed PCR products. The methodologyis based on the principle of reversed phase liquid chromatography and uses a unique DNA sepa...
متن کاملThe origin and evolution of the variability in a Y-specific satellite-DNA of Rumex acetosa and its relatives.
In this paper, we analyze a satellite-DNA family, the RAYSI family, which is specific of the Y chromosomes of Rumex acetosa, a dioecious plant species with a multiple sex-chromosome system in which the females are XX and the males are XY(1)Y(2). Here, we demonstrate that this satellite DNA is common to other relatives of R. acetosa, including Rumex papillaris, Rumex intermedius, Rumex thyrsoide...
متن کاملHuman Y-chromosome variation and male dysfunction
The Y-chromosome is responsible for sex determination in mammals, which is triggered by the expression of the SRY gene, a testis-determining factor. This particular gene, as well as other genes related to male fertility, are located in the non-recombining portion of the Y (NRY), a specific region that encompasses 95% of the human Y-chromosome. The other 5% is composed of the pseudo-autosomal re...
متن کاملvariation on the human Y chromosome
The Y chromosome is unusual in being constitutively haploid and escaping recombination for most of its length. This has led to a correspondingly unusual genomic landscape, rich in segmental duplications, which provide a rich environment for the generation of copy number variation (CNV). Interest in the chromosome comes from diverse fields, including infertility research, population genetics, fo...
