Lipophilic Constituents of Rumex vesicarius L. and Rumex dentatus L.
Rumex dentatus L. and Rumex vesicarius L., of the family Polygonaceae, are edible herbs growing wild in Egypt. Their lipoid constituents were examined by both liquid chromatography/mass spectrometry (LC/MS) and by gas chromatography/mass spectrometry (GC/MS). Their essential oil compositions consisted mainly of thujene, limonene, fenchon, estragole, and anethole but at largely different concent...
متن کاملVittadinia Triloba and Rumex Acetosella Communities in the Semi-arid Regions of the South Island
Floristics of Vittadinia triloba communities in Central Otago and the upper Waitaki valley and Rumex acetosella communities in the upper Waitaki, are compared with each other and with similar communities elsewhere in the South Island. Many species are common to all semi-arid areas, but each area has as its own special features, either the presence of a particular species or the greater abundanc...
متن کاملGenomic Loss and Silencing on the Y Chromosomes of Rumex
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 next-generation genome and transcriptome sequencing to investigate patterns of ongoing Y chromosome degen...
متن کاملRumex 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 کاملCloning and characterization of dispersed repetitive DNA derived from microdissected sex chromosomes of Rumex acetosa.
Rumex acetosa is characterized by a multiple chromosome system (2n = 12 + XX for females, and 2n = 12 + XY1Y2 for males), in which sex is determined by the ratio between the number of X chromosomes and autosome sets. For a better understanding of the molecular structure and evolution of plant sex chromosomes, we have generated a sex chromosome specific library of R. acetosa by microdissection. ...
