Histone Modifications in Transcriptional Activation during Plant Development
Abstract
In eukaryotic cell nuclei, chromatin states dictated by different combinations of post-translational modifications of histones, such as acetylation, methylation and monoubiquitination of lysine residues, are part of the multitude of epigenomes involved in the fine-tuning of all genetic functions and in particular transcription. During the past decade, an increasing number of 'writers', 'readers' and 'erasers' of histone modifications have been identified. Characterization of these factors in Arabidopsis has unraveled their pivotal roles in the regulation of essential processes, such as floral transition, cell differentiation, gametogenesis, and plant response/adaptation to environmental stresses. In this review we focus on histone modification marks associated with transcriptional activation to highlight current knowledge on Arabidopsis 'writers', 'readers' and 'erasers' of histone modifications and to discuss recent findings on molecular mechanisms of integration of histone modifications with the RNA polymerase II transcriptional machinery during transcription of the flowering repressor gene FLC.

In plants, HATs are organized into five structural subgroups, while HDACs are mainly grouped as HDA1 and HDA6; HDA6 is crucial for maintaining DNA methylation, suppressing transposable elements, and guiding development.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
