“…Modified by various PTMs such as acetylation, methylation, phosphorylation, etc., histone proteins regulate gene expression, DNA damage repair, DNA replication, and recombination ( Han et al., 2022 ; Millán-Zambrano et al., 2022 ). Transcriptional activation or repression depends on which histone residues are modified and the type of PTMs ( Sirko et al., 2022 ).…”

Understanding plant stress memory under extreme temperatures such as cold and heat could contribute to plant development. Plants employ different types of stress memories, such as somatic, intergenerational and transgenerational, regulated by epigenetic changes such as DNA and histone modifications and microRNAs (miRNA), playing a key role in gene regulation from early development to maturity. In most cases, cold and heat stresses result in short-term epigenetic modifications that can return to baseline modification levels after stress cessation. Nevertheless, some of the modifications may be stable and passed on as stress memory, potentially allowing them to be inherited across generations, whereas some of the modifications are reactivated during sexual reproduction or embryogenesis. Several stress-related genes are involved in stress memory inheritance by turning on and off transcription profiles and epigenetic changes. Vernalization is the best example of somatic stress memory. Changes in the chromatin structure of the Flowering Locus C (FLC) gene, a MADS-box transcription factor (TF), maintain cold stress memory during mitosis. FLC expression suppresses flowering at high levels during winter; and during vernalization, B3 TFs, cold memory cis-acting element and polycomb repressive complex 1 and 2 (PRC1 and 2) silence FLC activation. In contrast, the repression of SQUAMOSA promoter-binding protein-like (SPL) TF and the activation of Heat Shock TF (HSFA2) are required for heat stress memory. However, it is still unclear how stress memory is inherited by offspring, and the integrated view of the regulatory mechanisms of stress memory and mitotic and meiotic heritable changes in plants is still scarce. Thus, in this review, we focus on the epigenetic regulation of stress memory and discuss the application of new technologies in developing epigenetic modifications to improve stress memory.

“…At the same time, dissociated bZIP28 moves to the nucleus and causes induction of BiP3 gene expression by UPR. SCE1-mediated SUMOylation of DREB2A enhances its stability, which then binds to DRE-elements for inducing transcription of stress-responsive genes (Han et al, 2021(Han et al, , 2022 (Figure 4A). SUMO1 conjugation represses expression of heat-shock TF, AtHSFA2, during the recovery phase, and on second exposure to heat-shock, it gets deSUMOylated, inducing expression of heat-shock proteins.…”

“…For example, the mutated AtSIZ1, a SUMO Ligase, resulted in compromised tolerance to cold and drought, early flowering, and phosphate starvation symptoms (Ghimire et al, 2021 ). Hyper-SUMOylation under acute heat, cold, high salinity, drought, oxidative stress, and nutrient deficiency marks the conserved SUMO stress response (SSR) in plants (Miura et al, 2005 ; Catala et al, 2007 ; Chen et al, 2011 ; Ghimire et al, 2020 ; Roy and Sadanandom, 2021 ; Han et al, 2022 ). SIZ1-mediated SUMOylation positively responds to salt and drought-induced osmotic stress; enhances metal stress tolerance and light signaling; and regulates N, P, and ROS homeostasis in plants (Fang et al, 2022 ).…”

Post-translational modification (PTM) is a critical and rapid mechanism to regulate all the major cellular processes through the modification of diverse protein substrates. Substrate-specific covalent attachment of ubiquitin and Small Ubiquitin-Like Modifier (SUMO) with the target proteins, known as ubiquitination and SUMOylation, respectively, are crucial PTMs that regulate almost every process in the cell by modulating the stability and fidelity of the proteins. Ubiquitination and SUMOylation play a very significant role to provide tolerance to the plants in adverse environmental conditions by activating/deactivating the pre-existing proteins to a great extent. We reviewed the importance of ubiquitination and SUMOylation in plants, implicating its prospects in various abiotic stress regulations. An exhaustive study of molecular mechanisms of ubiquitination and SUMOylation of plant proteins and their role will contribute to the understanding of physiology underlying mitigation of the abiotic stresses and survival in plants. It will be helpful to strategize the improvement of crops for abiotic stress tolerance.

“…Low temperatures inhibit root and hypocotyl elongation, adult plant morphogenesis, and initiation of floral development (Ding et al 2019(Ding et al , 2020Ding and Yang 2022). Warm temperatures (below the heat stress range) result in plant thermomorphogenesis, showing dramatically elongated roots, hypocotyls, and petioles, as well as early flowering and accelerated leaf senescence (Casal and Balasubramanian 2019;Brightbill and Sung 2022;Han et al 2022). Cellular membranes, calcium (Ca 2+ ) channels, and rice CHILLING TOLERANCE DIVERGENCE 1 (COLD1) are responsible for low temperature sensing (Ma et al 2015;Guo et al 2018;Zhang et al 2019;Ding and Yang 2022).…”

PIFs- and COP1-HY5-mediated temperature signaling in higher plants

Plants have to cope with the surrounding changing environmental stimuli to optimize their physiological and developmental response throughout their entire life cycle. Light and temperature are two critical environmental cues that fluctuate greatly during day-night cycles and seasonal changes. These two external signals coordinately control the plant growth and development. Distinct spectrum of light signals are perceived by a group of wavelength-specific photoreceptors in plants. PIFs and COP1-HY5 are two predominant signaling hubs that control the expression of a large number of light-responsive genes and subsequent light-mediated development in plants. In parallel, plants also transmit low or warm temperature signals to these two regulatory modules that precisely modulate the responsiveness of low or warm temperatures. The core component of circadian clock ELF3 integrates signals from light and warm temperatures to regulate physiological and developmental processes in plants. In this review, we summarize and discuss recent advances and progresses on PIFs-, COP1-HY5- and ELF3-mediated light, low or warm temperature signaling, and highlight emerging insights regarding the interactions between light and low or warm temperature signal transduction pathways in the control of plant growth.
