Oikosin 4 and 6 were physically linked in a number of BAC clones.” “[Antibodies against splicing factors] failed to detect speckles in O. dioica endocycling nuclei and no interchromatin cluster granules were observed in the TEM images, suggesting these nuclei lack prominent splicing-factor domains.”"]]
- “Knobs” of heterochromatin strongly marked by H3K9me3 and enriched in H3K4me3 are prominent in
endocycling cells ([[Spada, Vincent and Thompson (2005)|biblio/15791412]]).
+ - Histone 3.3 phosphorylation is seen in mitotic and meiotic cells, but not in
+ endocycling ones ([[Schulmeister, Schmid and Thompson, 2007|biblio/17333540]]).
- Some 5-methylcytosine was detected by MeDIP-chip by ([[Navratilova et al., 2017|biblio/28115992]]).
- Chromatin domains are rarely longer than 7 nucleosomes ([[Navratilova et al., 2017|biblio/28115992]]).

- Expression of development genes is retarded by polyunsaturated aldehydes produced
by diatoms ([[Torres-Águila and coll., 2018|biblio/30272001]]).
- - Histone 3.3 phosphorylation is seen in mitotic and meiotic cells, but not in
- endocycling ones ([[Schulmeister, Schmid and Thompson, 2007|biblio/17333540]]).
+ - Endocycling cells show no polytenisation nor _in loco_ amplifications. Deep invaginations
