Abstract
Abstract
Plants grow in dynamic environments where they receive diverse environmental signals. Swift and precise control of gene expression is essential for plants to align their development and metabolism with fluctuating surroundings. Modifications on histones serve as “histone code” to specify chromatin and gene activities. Different modifications execute distinct functions on the chromatin, promoting either active transcription or gene silencing. Histone writers, erasers, and readers mediate the regulation of histone modifications by catalyzing, removing, and recognizing modifications, respectively. Growing evidence indicates the important function of histone modifications in plant development and environmental responses. Histone modifications also serve as environmental memory for plants to adapt to environmental changes. Here we review recent progress on the regulation of histone modifications in plants, the impact of histone modifications on environment-controlled developmental transitions including germination and flowering, and the role of histone modifications in environmental memory.Keywords: Histone modification,
Transcription,
