Secale cereale

We analysed thechromatin properties of both types of nuclei after firstand second pollen mitosis in rye (Secale cereale). Thecondensed chromatin of generativenuclei is ear- marked by an enhanced level of histone H3K4/K9dimethylation and H3K9 acetylation. Differences between rye and A. thaliana data suggestthat the chromatin organization in mature nuclei ofpollen grains is not universal across angiosperms.

In order to clarify the relationship between chromosomecondensation and histone modifications in different plantspecies, the present study analyzes the chromosomal dis-tribution of selected histone H3 modifications associatedwith transcriptional regulation and differentiation ofeuchromatin and heterochromatin (e.g. acetylation, phos-phorylation, and methylation of diverse residues)throughout all phases of both meiosis and mitosis.

In this study, through in situ localization of rye B-specific repetitive DNA families D1100 and E3900, we disclose that the B heterochromatic domain is consistently decondensed at interphase in two distinct genomic backgrounds of rye and also in a wheat(Triticum aestivum)–rye B addition line.

To investigate whether the dynamics of histone H3 phosphorylation differs between chromosomes with a different mode of segregation, we included in this study mitotic cells and also meiotic cells of individuals forming bivalents plus three different types of univalents (A chromosomes, B chromosomes and X chromosome).

In the present study, we performed comparative analysis of CENH3 variants expression in allopolyploids, as well as in different parental varieties of rye (Secale cereale L.) and wheat (Triticum aestivum L.).

In this paper the results of cytogenetic analysis of the secalotriticum hybrid karyotypes and the comparison of the CENH3 N-terminal domain structure of parent and hybrid forms are presented.

Through cytogenetic approaches using different plant species we show a detailed description of distribution patterns of phosphorylated histone H3 at either threonine 3 or threonine 32 in mitosis and meiosis.
