  • epigenetic
  • Although many aspects of the mechanisms and functions of H3K4me appear to be conserved among all three kingdoms, we observed significant differences in the relationship between H3K4me and transcription or other epigenetic pathways in plants and mammals. (biomedcentral.com)
  • haploid
  • The life cycle of flowering plants alternates between two heteromorphic generations: a diploid sporophytic generation and a haploid gametophytic generation. (biologists.org)
  • Against this, the plants can show mitotic divisions in both haploid and diploid cells. (aglasem.com)
  • From your recollection of examples of alternation of generations in plants (Chapter 3) identify plant species and stages at which mitosis is seen in haploid cells. (aglasem.com)
  • species
  • We aim for phylogenetic reconstruction to reveal major SERK groups across plant species (angiosperm to gymnosperm) for their functional diversification. (scirp.org)
  • stages
  • In multicellular animals gametogenesis takes place in special organs-the sex glands, or gonads (ovaries, testes, hermaphroditic sex glands), and takes place in three basic stages. (thefreedictionary.com)
  • proliferation
  • Expression of the T-DNA-encoded oncogenes triggers proliferation and differentiation of transformed plant cells. (prolekare.cz)
  • High concentrations of these phytohormones not only facilitate proliferation of transformed plant cells, but also differentiation of specialized cell types within the resulting crown gall tumor . (prolekare.cz)
  • Our results indicate that hyperproliferation caused by the loss of Rb protein prevents or delays cell determination during plant male gametogenesis, providing further evidence for a direct link between fate determination and cell proliferation. (le.ac.uk)
  • genome-wide
  • Furthermore, the preferential co-localization of H3K4me3 and H3K27me3 found in mammals does not appear to occur in plants at a genome-wide level, but H3K4me2 and H3K27me3 co-localize at a higher-than-expected frequency. (biomedcentral.com)
  • organ
  • This paper discusses and reviews the role of heterochrony in plant evolution at the organismal, organ, tissue, cellular, and molecular levels, as well as the relationships among heterochrony, heterotopy, and homeosis. (thefreelibrary.com)
  • fertility
  • Work is also in progress into the effects of abiotic and biotic stress and the role of hormones upon fertility in higher plants. (nottingham.ac.uk)
  • animals
  • This hypothesis has a strong appeal, as inbreeding can indeed be detrimental in many higher animals and plants [ 14 ], and high levels of inbreeding are harmful in some protists [ 15 ]. (royalsocietypublishing.org)
  • Constitutively heterochromatic centromeric regions in plants and animals are rich in highly repeated tandem arrays of satellite DNA and moderately repeated sequences, such as transposons, and show a low level of transcription. (embopress.org)
