“…Our previous studies showed that heat stress inhibited maize leaf growth and development (Hou et al, 2019;Wang et al, 2015). In this study, we found that the leaf length of the heat-tolerant line ZDH under high temperature (42 C) for 6 days decreased by nearly 7% compared to control (Figure 1B).…”

“…At the chromatin level, heat stress could induce programmed cell death and modulate chromatin structure, increasing histone acetylation and decreasing H3K9me3 ( Wang et al , 2015 b ). Moreover, in maize seedlings, application of a short-term heat stress induces dynamic H3K4me2 and H3K9ac alterations in promoter regions, which were associated with heat stress factor (Hsf) and rRNA gene up-regulation, accompanied by perturbations of cell membranes and increase in reactive oxygen species ( Hou et al , 2019 ).…”

To better adapt transiently or lastingly to stimuli from the surrounding environment, the chromatin states in plant cells vary to allow the cells to fine-tune their transcriptional profiles. Modifications of chromatin states involve a wide range of post-transcriptional histone modifications, histone variants, DNA methylation, and activity of non-coding RNAs, which can epigenetically determine specific transcriptional outputs. Recent advances in the area of ‘-omics’ of major crops have facilitated identification of epigenetic marks and their effect on plant response to environmental stresses. As most epigenetic mechanisms are known from studies in model plants, we summarize in this review recent epigenetic studies that may be important for improvement of crop adaptation and resilience to environmental changes, ultimately leading to the generation of stable climate-smart crops. This has paved the way for exploitation of epigenetic variation in crop breeding.

“…HDA9 induces net eviction of the H2A.Z histone variant from nucleosomes associated with YUCCA8, allowing binding and transcriptional activation by PIF4 and auxin accumulation [84]. In maize seedlings, HTS is observed to induce increased electrolyte leakage and hydrolytic activity of the plasma membrane and ROS, decondensed ribosomal DNA (rDNA) chromatin and the accompanied genome-wide increase of histone H3K4me2 and H3K9ac level and increase of HSF and rRNA gene expression [85]. Moreover, HT could result in transcriptional repression of genes associated with cell growth, such as histones and DNA polymerases and deregulation of DNA methylation and transposon activation [86].…”

During the past few years, climate change induced by global warming had caused the appearance of extreme high temperatures worldwide, which had resulted in devastating damage to crop production. High Temperature Stress (HTS) is becoming an increasingly significant problem for agricultural production. Recent studies have elucidated the complex regulatory networks and versatile metabolites involved in HTS tolerance. Here, we provided an overview of current knowledge regarding the adverse effect of HTS on plant growth and development, the impairment of HTS on photosynthesis and membrane system, the role of carbohydrate metabolism, accumulation of osmo-protectants and secondary metabolites, the induced production of Reactive Oxygen Species (ROSs) and ROS detoxification system, and the synthesis of protective proteins like Heat Shock Proteins (HSPs) in HTS tolerance. Furthermore, the role of different phytohormones in plant response to HTS were discussed and epigenetic modifications are reported to be one of the three major signaling pathways associated with HTS response in plants, through the development of a ‘stress memory’ that is generated by hypomethylation to improve the plant’s survival under recurring HTS conditions. These physiological and molecular knowledge underlying plant response to cope with HTS will be helpful for the future directions of breeding crop tolerance to HTS using these factors or other strategies for agricultural applications.
