Global climate change and associated adverse abiotic stress conditions, such as drought, salinity, heavy metals, waterlogging, extreme temperatures, oxygen deprivation, etc., greatly influence plant growth and development, ultimately affecting crop yield and quality, as well as agricultural sustainability in general. Plant cells produce oxygen radicals and their derivatives, so-called reactive oxygen species (ROS), during various processes associated with abiotic stress. Moreover, the generation of ROS is a fundamental process in higher plants and employs to transmit cellular signaling information in response to the changing environmental conditions. One of the most crucial consequences of abiotic stress is the disturbance of the equilibrium between the generation of ROS and antioxidant defense systems triggering the excessive accumulation of ROS and inducing oxidative stress in plants. Notably, the equilibrium between the detoxification and generation of ROS is maintained by both enzymatic and nonenzymatic antioxidant defense systems under harsh environmental stresses. Although this field of research has attracted massive interest, it largely remains unexplored, and our understanding of ROS signaling remains poorly understood. In this review, we have documented the recent advancement illustrating the harmful effects of ROS, antioxidant defense system involved in ROS detoxification under different abiotic stresses, and molecular cross-talk with other important signal molecules such as reactive nitrogen, sulfur, and carbonyl species. In addition, state-of-the-art molecular approaches of ROS-mediated improvement in plant antioxidant defense during the acclimation process against abiotic stresses have also been discussed.

Zinc-finger proteins, a superfamily of proteins with a typical structural domain that coordinates a zinc ion and binds nucleic acids, participate in the regulation of growth, development, and stress adaptation in plants. Most zinc fingers are C2H2-type or CCCC-type, named after the configuration of cysteine (C) and histidine (H); the less-common CCCH zinc-finger proteins are important in the regulation of plant stress responses. In this review, we introduce the domain structures, classification, and subcellular localization of CCCH zinc-finger proteins in plants and discuss their functions in transcriptional and post-transcriptional regulation via interactions with DNA, RNA, and other proteins. We describe the functions of CCCH zinc-finger proteins in plant development and tolerance to abiotic stresses such as salt, drought, flooding, cold temperatures and oxidative stress. Finally, we summarize the signal transduction pathways and regulatory networks of CCCH zinc-finger proteins in their responses to abiotic stress. CCCH zinc-finger proteins regulate the adaptation of plants to abiotic stress in various ways, but the specific molecular mechanisms need to be further explored, along with other mechanisms such as cytoplasm-to-nucleus shuttling and post-transcriptional regulation. Unraveling the molecular mechanisms by which CCCH zinc-finger proteins improve stress tolerance will facilitate the breeding and genetic engineering of crops with improved traits.

“…The rcd1 mutant displays an enhanced tolerance to chloroplastic superoxide formation (Fujibe et al, 2004). In addition, RCD1 is also involved in abiotic stress through interaction with SALT OVERLY SENSITIVE 1 (SOS1) (Katiyar-Agarwal et al, 2006;Wang et al, 2020). In Oryza sativa (rice), the loss-of-function of OsSRO1c results in plants exhibiting pronounced drought sensitivity, as well as a greater tolerance to oxidative stress (You et al, 2013(You et al, , 2014.…”

Maize SRO1e represses anthocyanin synthesis through regulating the MBW complex in response to abiotic stress

et al. 2020

Plants experiencing abiotic stress react by generating reactive oxygen species (ROS), compounds that, if allowed to accumulate to excess, repress plant growth and development. Anthocyanins induced by abiotic stress are strong antioxidants that neutralize ROS, whereas their over-accumulation retards plant growth. Although the mechanism of anthocyanin synthesis has been revealed, how plants balance anthocyanin synthesis under abiotic stress to maintain ROS homeostasis is unknown. Here, ROS-related proteins, SIMILAR TO RCD-ONEs (SROs), were analysed in Zea mays (maize), and all six SRO1 genes were inducible by a variety of abiotic stress agents. The constitutive expression of one of these genes, ZmSRO1e, in maize as well as in Arabidopsis thaliana increased the sensitivity of the plant to abiotic stress, but repressed anthocyanin biosynthesis and ROS scavenging activity. Loss-of-function mutation of ZmSRO1e enhanced ROS tolerance and anthocyanin accumulation. We showed that ZmSRO1e competed with ZmR1 (a core basic helix-loop-helix subunit of the MYB-bHLH-WD40 transcriptional activation complex) for binding with ZmPL1 (a core MYB subunit of the complex). Thus, during the constitutive expression of ZmSRO1e, the formation of the complex was compromised, leading to the repression of genes, such as ZmA4 (encoding dihydroflavonol reductase), associated with anthocyanin synthesis. Overall, the results have revealed a mechanism that allows the products of maize SRO1e to participate in the abiotic stress response.
