Plant histone modifications in response to cold stress

Cold stress is a major environmental factor limiting agricultural expansion and crop yields, plants have developed diverse molecular mechanisms to cope with lifetime of exposure cold stress. Histone modifications play fundamental role in regulating chromatin dynamics transcriptional activation, either directly or through protein adaptors termed effectors. Growing evidence indicates that the remodeling caused by histone modifications, including acetylation, methylation, phosphorylation, ubiquitination, required for stress-responsive transcription, adaptation, memory plants. In this mini-review, I summarized current knowledge regarding associated plant responses stress, discussed roles these improving tolerance.
