Heritable gfp silencing was seen in embryonic-, larval-, and adult-stage inheriting progeny (Fig. 1 A and B). F2 progeny did not exhibit gfp silencing.

Witryna14 cze 2024 · Somatically heritable silencing of FLC is initially triggered by non-coding RNAs, which are involved in recruitment of components of PRC2, which catalyze H3K27me3, which in turn mediates a somatically heritable silent state . Importantly, H3K27me3 at genes like FLC is erased each generation, both in pollen and in the … Witryna27 maj 2004 · Epigenetic mechanisms, which involve DNA and histone modifications, result in the heritable silencing of genes without a change in their coding sequence.
