Environmental stresses are ubiquitous and unavoidable to all living things. Organisms respond and adapt to stresses through defined regulatory mechanisms that drive changes in gene expression, organismal morphology, or physiology. Immune responses illustrate adaptation to bacterial and viral biotic stresses in animals. Dysregulation of the genotoxic stress response system is frequently associated with various types of human cancer. With respect to plants, especially halophytes, complicated systems have been developed to allow for plant growth in high salt environments. In addition, drought, waterlogging, and low temperatures represent other common plant stresses. In this review, we summarize representative examples of organismal response and adaptation to various stresses. We also discuss the molecular mechanisms underlying the above phenomena with a focus on the improvement of organismal tolerance to unfavorable environments.

“…Furthermore, OsCYCB1 overexpression increased resistance to cold stress (Ma et al, 2009). Moreover, many other coldresponsive genes have been identified in T. salsuginea and rice by RNA-sequencing Liu et al, 2016;Wang et al, 2017). The T. salsuginea gene FILAMENTOUS TEMPERATURE-SENSITIVE H8 was shown to alleviate cold-induced photoinhibition .…”

Cell Cycle Regulation in the Plant Response to Stress

As sessile organisms, plants face a variety of environmental challenges. Their reproduction and survival depend on their ability to adapt to these stressors, which include water, heat stress, high salinity, and pathogen infection. Failure to adapt to these stressors results in programmed cell death and decreased viability, as well as reduced productivity in the case of crop plants. The growth and development of plants are maintained by meiosis and mitosis as well as endoreduplication, during which DNA replicates without cytokinesis, leading to polyploidy. As in other eukaryotes, the cell cycle in plants consists of four stages (G1, S, G2, and M) with two major check points, namely, the G1/S check point and G2/M check point, that ensure normal cell division. Progression through these checkpoints involves the activity of cyclin-dependent kinases and their regulatory subunits known as cyclins. In order for plants to survive, cell cycle control must be balanced with adaption to dynamic environmental conditions. In this review, we summarize recent advances in our understanding of cell cycle regulation in plants, with a focus on the molecular interactions of cell cycle machinery in the context of stress tolerance. FIGURE 1 | Schematic representation of the mitotic cell cycle in plants.At the G1 phase, D-type cyclins (CYCD) interact with the A-type CDK (CDKA), forming the CDKA/CYCD complex. The activity of CDKA/CYCD complex can be negatively regulated by KPR and SIM proteins. Once activation, this complex phosphorylates RBR to release the transcript factor E2Fa/b-DP. This E2Fa/b-DP complex binds to the E2F box and activate the transcription of S phase genes. At the G2 and M phase S, CYCA and CYCB are strongly expressed and their gene products assemble with CDKA and CDKB. The CYCD can also associate with CDKs. At the beginning of G2 phase, CDK activity are inhibited because of the phosphorylation of Y14 and T15 site by WEEI kinase. The CDC25-related kinase, which removes the inhibitory phosphate groups, still needs to be identified. Once the CDK/CYC complex are active, they phosphorylate MYB3R transcription factors and activate mitotic genes' transcription. Mitotic exit requires anaphase-promoting complex (APC), which degrades cyclins through ubiquitin-proteasome pathway.

“…Single‐celled organisms, including bacteria and yeast, have developed mechanisms to survive in the face of environmental stresses by promoting mutagenesis, thereby increasing genetic diversity . These adaptations involve increased genomic instability and mutation, coupled with changes to signaling pathways and gene expression programs, creating an intricate network that researchers have been trying to unravel in recent years . Uncovering the molecular mechanisms by which plants and microorganisms respond to stresses will help us to better understand biological evolution .…”

Similar to bacteria, yeast, and other organisms that have evolved pathways to respond to environmental stresses, cancer cells develop mechanisms that increase genetic diversity to facilitate adaptation to a variety of stressful conditions, including hypoxia, nutrient deprivation, exposure to DNA‐damaging agents, and immune responses. To survive, cancer cells trigger mechanisms that drive genomic instability and mutation, alter gene expression programs, and reprogram the metabolic pathways to evade growth inhibition signaling and immune surveillance. A deeper understanding of the molecular mechanisms that underlie the pathways used by cancer cells to overcome stresses will allow us to develop more efficacious strategies for cancer therapy. Herein, we overview several key stresses imposed on cancer cells, including oxidative, metabolic, mechanical, and genotoxic, and discuss the mechanisms that drive cancer cell responses. The therapeutic implications of these responses are also considered, as these factors pave the way for the targeting of stress adaption pathways in order to slow cancer progression and block resistance to therapy.
