“…Reduced photosynthesis during prolonged abiotic stresses such as drought and flooding can be correlated with the production of ROS (Klok et al, 2002 ). High levels of ROS can damage the cell through peroxidation of the lipids, oxidation of proteins and other pathways, and finally the death of the cell (Clement et al, 2008 ; Wrzaczek et al, 2011 ). Glutathione S-transferase, one of the important enzyme in the regulation of ROS flux, is featured as a highly enriched gene among the top 50 highly expressed genes under flooding stress in this study, which indicates another adaptive response under the stress conditions (Table 3 ).…”

Drought and flooding are two major causes of severe yield loss in soybean worldwide. A lack of knowledge of the molecular mechanisms involved in drought and flood stress has been a limiting factor for the effective management of soybeans; therefore, it is imperative to assess the expression of genes involved in response to flood and drought stress. In this study, differentially expressed genes (DEGs) under drought and flooding conditions were investigated using Illumina RNA-Seq transcriptome profiling. A total of 2724 and 3498 DEGs were identified under drought and flooding treatments, respectively. These genes comprise 289 Transcription Factors (TFs) representing Basic Helix-loop Helix (bHLH), Ethylene Response Factors (ERFs), myeloblastosis (MYB), No apical meristem (NAC), and WRKY amino acid motif (WRKY) type major families known to be involved in the mechanism of stress tolerance. The expression of photosynthesis and chlorophyll synthesis related genes were significantly reduced under both types of stresses, which limit the metabolic processes and thus help prolong survival under extreme conditions. However, cell wall synthesis related genes were up-regulated under drought stress and down-regulated under flooding stress. Transcript profiles involved in the starch and sugar metabolism pathways were also affected under both stress conditions. The changes in expression of genes involved in regulating the flux of cell wall precursors and starch/sugar content can serve as an adaptive mechanism for soybean survival under stress conditions. This study has revealed the involvement of TFs, transporters, and photosynthetic genes, and has also given a glimpse of hormonal cross talk under the extreme water regimes, which will aid as an important resource for soybean crop improvement.

“…SRO is a plant-specific protein group that has the PARP, RST and WWE domain [ 270 ]. The rcd1 [ radical-induced cell death1 ] in Arabidopsis exhibited the ability to respond to various stimuli such as ROS stress, salt stress, and irradiation by interacting with numerous transcription factors that facilitate their involvement in developmental and stress-related responses [ 27 , 271 , 272 ]. The RCD1 gene regulates signaling pathways that are responsible for quantitative changes to gene expression in response to ROS [ 273 ].…”

Climate change-induced abiotic stress results in crop yield and production losses. These stresses result in changes at the physiological and molecular level that affect the development and growth of the plant. Reactive oxygen species (ROS) is formed at high levels due to abiotic stress within different organelles, leading to cellular damage. Plants have evolved mechanisms to control the production and scavenging of ROS through enzymatic and non-enzymatic antioxidative processes. However, ROS has a dual function in abiotic stresses where, at high levels, they are toxic to cells while the same molecule can function as a signal transducer that activates a local and systemic plant defense response against stress. The effects, perception, signaling, and activation of ROS and their antioxidative responses are elaborated in this review. This review aims to provide a purview of processes involved in ROS homeostasis in plants and to identify genes that are triggered in response to abiotic-induced oxidative stress. This review articulates the importance of these genes and pathways in understanding the mechanism of resistance in plants and the importance of this information in breeding and genetically developing crops for resistance against abiotic stress in plants.

“…One evidence in this regard is regulation of natriuretic peptide receptor 1 (NPR1) by an intracellular redox potential, which results in its monomerization and translocation to the nucleus where it up-regulates defense responsive genes (Rao and Chaitanya 2016). A grim reaper (GRI) protein is another strong candidate for ROS sensing (Wrzaczek et al 2011). Peptides derived by GRI may induce cell death in response to the presence of superoxide radicals, but experimental evidence is required to support this mechanism.…”

The climate shift has resulted in frequent heat waves, which cause damaging effects on plant growth and development at different life stages. All cellular processes in plants are highly sensitive to a high temperature. The plasma membrane heat receptors usually sense temperature variations directly or via a change in membrane fluidity. The accumulation of damaged proteins and reactive oxygen species also aid in heat perception. Calcium ions and heat sensors transfer signals to transcription factors through a series of signaling cascades. The heat stress transcription factors (HSFs) effectively regulate expression of heat induced genes. The members of the heat shock transcription factor A1 (HsfA1s) family are master regulators of a heat stress response. Different HSFs interact with each other at different levels and simultaneously operate heat induced gene expression. Interaction of HSFs with each other on multiple levels provides chances for manipulation to improve plant heat stress tolerance.
