Germline chromatin.
The DNA in eukaryotes is wrapped around a histone octamer core, together comprising the main subunit of chromatin, the nucleosome. Modifications of the nucleosomal histones in the genome correlate with the ability or inability of chromatin to form higher order structures, that in turn influence gene activity. The genome in primordial germ cells in early C. elegans germ cells carries a unique pa...
متن کاملChromatin regulation during C. elegans germline development.
Recent studies in Caenorhabditis elegans implicate PcG- and NuRD-like chromatin regulators in the establishment and maintenance of germline-soma distinctions. Somatic cells appear to utilize NuRD-related nucleosome-remodeling factors to overwrite germline-specific chromatin states that are specified through PcG-like activities. The germline, in turn, may rely on an asymmetrically inherited inhi...
متن کاملChromatin Reprogramming: Gender Equality during Arabidopsis Germline Differentiation
Large-scale histone H3 reprogramming during male germline differentiation is conserved between animals and plants. A new report now shows that histone H3 reprogramming also occurs in the female germline of the flowering plant Arabidopsis thaliana.
متن کاملPostmeiotic Sex Chromatin in the Male Germline of Mice
In mammals, the X and Y chromosomes are subject to meiotic sex chromosome inactivation (MSCI) during prophase I in the male germline, but their status thereafter is currently unclear. An abundance of X-linked spermatogenesis genes has spawned the view that the X must be active . On the other hand, the idea that the imprinted paternal X of the early embryo may be preinactivated by MSCI suggests ...
متن کاملEctopic expression of germline genes and HTA are suppressed by loss of MES-4, the MES-2/3/6 complex and other germline chromatin modifiers. Our findings suggest that synMuv B(+) function antagonizes a germline chromatin state in somatic
INTRODUCTION The development of an organism relies on a series of cell fate decisions. One of the most pivotal of these decisions is that between soma and germ line. It is important to specify a small number of germ cells within a mostly somatic organism in order to ensure both the survival of the individual and its fertility. The single-cell embryo has a number of attributes of the germ line, ...
