Plants can show remarkable responses to small changes in temperature, yet one of the
great unknowns in plant science is how that temperature signal is perceived. The identity of …

Vernalization is the promotion of the competence for flowering by long periods of low
temperatures such as those typically experienced during winters. In Arabidopsis, the …

There is now mounting evidence that heritable variation in ecologically relevant traits can be
generated through a suite of epigenetic mechanisms, even in the absence of genetic …

RICE FLOWERING LOCUS T 1 (RFT1/FT-L3) is the closest homologue of Heading date 3a
(Hd3a), which is thought to encode a mobile flowering signal and promote floral transition …

Vernalization, the acceleration of flowering by winter, involves cold-induced epigenetic
silencing of Arabidopsis FLC. This process has been shown to require conserved Polycomb …

Post-translational modification of histone N-tails affects eukaryotic gene activity. In
Arabidopsis, the histone modification level correlates with gene activation and repression in …

Histone modification in chromatin is one of the key control points in gene regulation in
eukaryotic cells. Protein complexes composed of histone acetyltransferase or deacetylase …

Histone lysines can be mono-, di-, or trimethylated, providing an ample magnitude of
epigenetic information for transcription regulation. In fungi, SET2 is the sole …

Trithorax function is essential for epigenetic maintenance of gene expression in animals, but
little is known about trithorax homologs in plants. ARABIDOPSIS TRITHORAX1 (ATX1) was …

Ubiquitination is one of many known histone modifications that regulate gene expression.
Here, we examine the Arabidopsis thaliana homologs of the yeast E2 and E3 enzymes …
