“…ABA and drought stress induced the expression of chromatin remodeling gene PsSNF5 ( Pisum sativum SNF5 ). PsSNF5 interacts with Arabidopsis SWI3-like proteins (SWI3A and SWI3B), which in turn interact with FCA [45,46]. ABA-induced SNF5 and FCA may regulate flowering time and stress responses through chromatin remodeling.…”

Gene expression driven by developmental and stress cues often depends on nucleosome histone post-translational modifications and sometimes on DNA methylation. A number of studies have shown that these DNA and histone modifications play a key role in gene expression and plant development under stress. Most of these stress-induced modifications are reset to the basal level once the stress is relieved, while some of the modifications may be stable, that is, may be carried forward as ‘stress memory’ and may be inherited across mitotic or even meiotic cell divisions. Epigenetic stress memory may help plants more effectively cope with subsequent stresses. Comparative studies on stress-responsive epigenomes and transcriptomes will enhance our understanding of stress adaptation of plants.

“…Through the action of a number of known transcription factors, ABA-dependent and independent pathways can be induced by drought [7], which results in the activation of Late Embryogenesis-Dependent (LEA) protein synthesis, active oxygen scavenging enzymes, and osmolytes [8,9]. At the epigenetic level, evidence suggests that DNA methylation, histone modification and chromatin remodeling are related to regulating the plant response to drought [10,11,12]. …”

Alfalfa, an important forage legume, is an ideal crop for sustainable agriculture and a potential crop for bioenergy resources. Drought, one of the most common environmental stresses, substantially affects plant growth, development, and productivity. MicroRNAs (miRNAs) are newly discovered gene expression regulators that have been linked to several plant stress responses. To elucidate the role of miRNAs in drought stress regulation of alfalfa, a high-throughput sequencing approach was used to analyze 12 small RNA libraries comprising of four samples, each with three biological replicates. From the 12 libraries, we identified 348 known miRNAs belonging to 80 miRNA families, and 281 novel miRNAs, using Mireap software. Eighteen known miRNAs in roots and 12 known miRNAs in leaves were screened as drought-responsive miRNAs. With the exception of miR319d and miR157a which were upregulated under drought stress, the expression pattern of drought-responsive miRNAs was different between roots and leaves in alfalfa. This is the first study that has identified miR3512, miR3630, miR5213, miR5294, miR5368 and miR6173 as drought-responsive miRNAs. Target transcripts of drought-responsive miRNAs were computationally predicted. All 447 target genes for the known miRNAs were predicted using an online tool. This study provides a significant insight on understanding drought-responsive mechanisms of alfalfa.

Plants respond and adapt to drought, cold and high-salinity stress in order to survive. Molecular and genomic studies have revealed that many stress-inducible genes with various functions and signalling factors, such as transcription factors, protein kinases and protein phosphatases, are involved in the stress responses. Recent studies have revealed the coordination of the gene expression and chromatin regulation in response to the environmental stresses. Several histone modifications are dramatically altered on the stress-responsive gene regions under drought stress conditions. Several chromatin-related proteins such as histone modification enzymes, linker histone H1 and components of chromatin remodeling complex influence the gene regulation in the stress responses. This review briefly describes chromatin regulation in response to drought, cold and highsalinity stress.
