“…WRKY TFS participate in ROS signaling, plant hormone signal transduction pathways, and the mitogen-activated protein kinase (MAPK) cascade in response to abiotic stress. These reactions are intertwined with the interactions of many plant hormones, calcium and different ROS, as well as a large number of receptors; related enzymes; phosphatases; and other regulatory proteins, compounds and small molecules [ 93 , 94 ]. Plants can adjust their biological activities according to various environmental and internal signals.…”

“…Studies have shown that wheat is sensitive to final high temperatures, leading to a sharp decline in grain quality and yield. Overall, in the defense mechanism network regulated by the MAPK cascade in plants, the MAPK cascade acts as the main switch (signal/sensory protein molecule) that regulates high-temperature stress by triggering WRKY TF and stress-related gene expression [ 93 ]. In summary, WRKY TFs may respond to high-temperature stress and thus form a network-like regulatory system, which reflects the complexity and diversity of the regulation of abiotic stress-related gene processes in plants ( Figure 3 ).…”

Plant growth and development are closely related to the environment, and high-temperature stress is an important environmental factor that affects these processes. WRKY transcription factors (TFs) play important roles in plant responses to high-temperature stress. WRKY TFs can bind to the W-box cis-acting elements of target gene promoters, thereby regulating the expression of multiple types of target genes and participating in multiple signaling pathways in plants. A number of studies have shown the important biological functions and working mechanisms of WRKY TFs in plant responses to high temperature. However, there are few reviews that summarize the research progress on this topic. To fully understand the role of WRKY TFs in the response to high temperature, this paper reviews the structure and regulatory mechanism of WRKY TFs, as well as the related signaling pathways that regulate plant growth under high-temperature stress, which have been described in recent years, and this paper provides references for the further exploration of the molecular mechanisms underlying plant tolerance to high temperature.

“…MAPKs play important roles in regulating responses to abiotic stress. They have been linked to oxidative stress tolerance under heat stress in wheat (47) and are involved in the heat stress response in Arabidopsis , maize and rice (48).

Global warming is one of the most significant threats to food security. With temperatures predicted to rise and extreme weather events becoming more common we must safeguard food production by developing crop varieties that are more tolerant to heat stress without compromising yield under favourable conditions. By evaluating 149 spring wheat lines in the field under yield potential and heat stressed conditions, we demonstrate how strategic integration of exotic material significantly increases yield under heat stress compared to elite lines, with no significant yield penalty under favourable conditions. Genome-wide association analysis revealed three marker trait associations, which together increase yield under heat stress by over 50% compared to lines without the advantageous alleles and was associated with approximately 2°C lower canopy temperature. We identified an Aegilops tauschii introgression underlying the most significant of these associations. By comparing overlapping recombination of this introgressed segment between lines, we identified a 1.49Mbp region of the introgression responsible for this association that increases yield under heat stress by 32.4%. The genes within this region were extracted from diverse Ae. tauschii genomes, revealing a novel Ae. tauschii MAPK gene, a SOC1 orthologue and a pair of type-B two-component response regulators. Incorporating these exotic alleles into breeding programmes could serve as a pre-emptive strategy to produce high yielding wheat cultivars that are resilient to the effects of future climate uncertainty with no yield penalty under favourable conditions.

“…In addition, UV-B, heat stress, etc. can activate MPK3/6 signaling, act on the downstream transcription factor EIN3 to induce the accumulation of chitinase or activate the expression of disease process-related proteins (PR) and CAT-encoding genes ( Rakwal et al, 2004 ; Yoo et al, 2008 ; Bethke et al, 2009 ; An et al, 2010 ; An et al, 2021 ; Kumar et al, 2021 ). 12 C ion beam radiation treatment resulted in differential upregulation of mitogen-activated protein kinase 3 (MPK3), mitogen-activated protein kinase 5 (MKK5), disease process-related protein (PR1), chitinase (ChiB) and CAT, while 7 Li PR1 and ChiB were differentially downregulated in the ion beam treated group.…”

Novel genetic variations can be obtained by inducing mutations in the plant which help to achieve novel traits. The useful mutant can be obtained through radiation mutation in a short period which can be used as a new material to produce new varieties with high yield and good quality wheat. In this paper, the proteomic analysis of wheat treated with different doses of 12C and 7Li ion beam radiation at the seedling stage was carried out through a Tandem Mass Tag (TMT) tagging quantitative proteomic analysis platform based on high-resolution liquid chromatography-mass spectrometry, and the traditional 60Co-γ-ray radiation treatment for reference. A total of 4,764 up-regulated and 5,542 down-regulated differentially expressed proteins were identified. These proteins were mainly enriched in the KEGG pathway associated with amino acid metabolism, fatty acid metabolism, carbon metabolism, photosynthesis, signal transduction, protein synthesis, and DNA replication. Functional analysis of the differentially expressed proteins showed that the oxidative defense system in the plant defense system was fully involved in the defense response after 12C ion beam and 7Li ion beam radiation treatments. Photosynthesis and photorespiration were inhibited after 12C ion beam and 60Co-γ-ray irradiation treatments, while there was no effect on the plant with 7Li ion beam treatment. In addition, the synthesis of biomolecules such as proteins, as well as multiple signal transduction pathways also respond to radiations. Some selected differentially expressed proteins were verified by Parallel Reaction Monitoring (PRM) and qPCR, and the experimental results were consistent with the quantitative results of TMT. The present study shows that the physiological effect of 12C ion beam radiation treatment is different as compared to the 7Li ion beam, but its similar to the 60Co-γ ray depicting a significant effect on the plant by using the same dose. The results of this study will provide a theoretical basis for the application of 12C and 7Li ion beam radiation in the mutation breeding of wheat and other major crops and promote the development of heavy ion beam radiation mutation breeding technology.
