Genetic degeneration of old and young Y chromosomes in the flowering plant Rumex hastatulus.

Logáil Isteach / Cláraigh
Heteromorphic sex chromosomes have originated independently in many species, and a common feature of their evolution is the degeneration of the Y chromosome, characterized by a loss of gene content and function. Despite being of broad significance to our understanding of sex chromosome evolution,
Toxicological deterioration of some plant extracts on Fannia canicularis (Diptera: Muscidae).

The early third instar larvae of Fannia canicularis were treated with various concentrations of Rumex dentatus, Protulaca deracea and Piper cubebae extracts. The Rumex dentatus was more toxic than Protulaca deracea and Piper cubebae. The extract mixture of Rumex dentatus and Piper cubebae induced a

X and Y sex chromosomes from the dioecious plant Silene latifolia (white campion) were isolated from mitotic metaphase chromosome preparations on polyester membranes. Autosomes were ablated using an argon ion laser microbeam and isolated sex chromosomes were then recovered on excised fragments of
Chromosome painting of Y chromosomes and isolation of a Y chromosome-specific repetitive sequence in the dioecious plant Rumex acetosa.

The dioecious plant Rumex acetosa has a multiple sex chromosome system: XX in female and XY(1)Y(2) in male. Both types of Y chromosome were isolated from chromosome spreads of males by manual microdissection, and their chromosomal DNA was amplified using degenerate oligonucleotide primed-polymerase
The 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

BACKGROUND
Rumex crispus root has traditionally been used in Asian medicine for the treatment of hemorrhage and dermatolosis. The aim of this study was to explore the pharmaceutical effects of water extract of Rumex crispus (WERC) on osteoblast and osteoclast differentiation. We also studied the

1. Male and female Y-chromosome hyperploid plants were obtained and morphologically and cytologically investigated. 2. Conjugation of sex chromosomes was investigated in ♂ plants with 1, 2 and 3 additional Y chromosomes. Conjugation between sex chromosomes was end-to-end. Association between

Ten of 100 mature ewes were afflicted with acute oxalate toxicosis within 40 hours after being temporarily penned in a lot that contained considerable growing Rumex crispus (curly dock). Clinical signs of toxicosis included excess salivation, tremors, ataxia, and recumbency. Affected ewes were

A satellite-DNA family (RUSI) has been isolated and characterized in Rumexinduratus Boiss and Reuter (Polygonaceae), an Iberian endemic polygamous sorrel. The RUSI repeats are 170 bp in length and approximately 68% AT-rich containing different variants of degenerate telomere motifs--(TT)(n)AN(GG)(n)

Across many unrelated lineages of plants and animals, Y chromosomes show a recurrent pattern of gene degeneration and loss, but the relative importance of inefficient selection, adaptive gene silencing, and neutral genetic drift in causing degeneration remain poorly understood. Here, we use

Recent molecular and genomic studies carried out in a number of model dioecious plant species, including Asparagus officinalis, Carica papaya, Silene latifolia, Rumex acetosa and Marchantia polymorpha, have shed light on the molecular structure of both homomorphic and heteromorphic sex chromosomes,

Around six percent of flowering species are dioecious, with separate female and male individuals. Sex determination is mostly based on genetics, but morphologically distinct sex chromosomes have only evolved in a few species. Of these, heteromorphic sex chromosomes have been most clearly described

Sex chromosomes are unique regions of the genome, with a host of properties that distinguish them from autosomes and from each other. Although there is extensive theory describing sex chromosome formation and subsequent degeneration of the Y chromosome, the relative importance of processes governing
