“…Almost 80% of these 330 PK-encoding DEGs belonged to the receptor-like kinase (RLK)/Pelle gene family, the largest class of PKs ( Figure 4 C), and predominantly (185; 71%) upregulated in response to UV. This group is stress-specific defense-related PKs that facilitate a signaling cascade for plant adaptation under various stresses [ 47 ]. The Mitogen-activated protein kinases (MAPKs), another family of PKs that play diverse roles in response to abiotic and biotic stresses, had three members activated by UV exposure and only one downregulated.…”

“…Together with these plant regulator families, kinases also act as key integrators of different stress signaling pathways and are suggested to be one of the potential mechanisms underlying plant priming and induction of systemic acquired resistance (SAR) [ 20 , 85 ]. Here, UV-C caused a general activation of A. stenosperma RLK/Pelle kinases that constitutes one of the largest subfamilies of defense-related proteins, acting as a signaling cascade to protect plants against an ever-changing population of stress elicitors [ 47 ].…”

Stress priming is an important strategy for enhancing plant defense capacity to deal with environmental challenges and involves reprogrammed transcriptional responses. Although ultraviolet (UV) light exposure is a widely adopted approach to elicit stress memory and tolerance in plants, the molecular mechanisms underlying UV-mediated plant priming tolerance are not fully understood. Here, we investigated the changes in the global transcriptome profile of wild Arachis stenosperma leaves in response to UV-C exposure. A total of 5751 differentially expressed genes (DEGs) were identified, with the majority associated with cell signaling, protein dynamics, hormonal and transcriptional regulation, and secondary metabolic pathways. The expression profiles of DEGs known as indicators of priming state, such as transcription factors, transcriptional regulators and protein kinases, were further characterized. A meta-analysis, followed by qRT-PCR validation, identified 18 metaDEGs as being commonly regulated in response to UV and other primary stresses. These genes are involved in secondary metabolism, basal immunity, cell wall structure and integrity, and may constitute important players in the general defense processes and establishment of a priming state in A. stenosperma. Our findings contribute to a better understanding of transcriptional dynamics involved in wild Arachis adaptation to stressful conditions of their natural habitats.

“…An important association was detected on chromosome 2A with the CRK and FLRI abiotic-related trait. Many studies suggest the involvement of CRK proteins in plant development, cell death, immunity, and responses to abiotic stresses ( Shumayla et al., 2019 ). A gene related to carbohydrate metabolism, the alpha-L-fucosidase 2-like was detected on chromosome 4A and co-localized with MQTL for wheat quality.…”

Wild emmer (Triticum turgidum ssp. dicoccoides) genotypes were studied for their high-nutritional value and good tolerance to various types of stress; for this reason, several QTL (quantitative trait loci) studies have been conducted to find favorable alleles to be introgressed into modern wheat cultivars. Given the complexity of the QTL nature, their interaction with the environment, and other QTLs, a small number of genotypes have been used in wheat breeding programs. Meta-QTL (MQTL) analysis helps to simplify the existing QTL information, identifying stable genomic regions and possible candidate genes for further allele introgression. The study aimed to identify stable QTL regions across different environmental conditions and genetic backgrounds using the QTL information of the past 14 years for different traits in wild emmer based upon 17 independent studies. A total of 41 traits were classified as quality traits (16), mineral composition traits (11), abiotic-related traits (13), and disease-related traits (1). The analysis revealed 852 QTLs distributed across all 14 chromosomes of wild emmer, with an average of 61 QTLs per chromosome. Quality traits had the highest number of QTLs (35%), followed by mineral content (33%), abiotic-related traits (28%), and disease-related traits (4%). Grain protein content (GPC) and thousand kernel weight (TKW) were associated with most of the QTLs detected. A total of 43 MQTLs were identified, simplifying the information, and reducing the average confidence interval (CI) from 22.6 to 4.78 cM. These MQTLs were associated with multiple traits across different categories. Nine candidate genes were identified for several stable MQTLs, potentially contributing to traits such as quality, mineral content, and abiotic stress resistance. These genes play essential roles in various plant processes, such as carbohydrate metabolism, nitrogen assimilation, cell wall biogenesis, and cell wall extensibility. Overall, this study underscores the importance of considering MQTL analysis in wheat breeding programs, as it identifies stable genomic regions associated with multiple traits, offering potential solutions for improving wheat varieties under diverse environmental conditions.

“…Transcriptome studies have identified dramatic changes in the levels of non-coding RNAs in response to temperature changes. For example, in wheat stress signaling responses, e.g., to high or low temperatures and to drought, which often have the consequence of accelerating or aborting floral development, large increases in non-coding RNA expression have been reported ( [41,42]). One of the major outstanding challenges is to identify the targets of these non-coding RNAs and further understand the function in temperature signaling.…”

Temperature is a critical environmental signal in the regulation of plant growth and development. The temperature signal varies across a daily 24 h period, between seasons and stochastically depending on local environmental events. Extracting important information from these complex signals has led plants to evolve multiple temperature responsive regulatory mechanisms at the molecular level. In temperate cereals, we are starting to identify and understand these molecular mechanisms. In addition, we are developing an understanding of how this knowledge can be used to increase the robustness of crop yield in response to significant changes in local and global temperature patterns. To enable this, it is becoming apparent that gene regulation, regarding expression and post-transcriptional regulation, is crucial. Large transcriptomic studies are identifying global changes in spliced transcript variants and regulatory non-coding RNAs in response to seasonal and stress temperature signals in many of the cereal crops. Understanding the functions of these variants and targets of the non-coding RNAs will greatly increase how we enable the adaptation of crops. This review considers our current understanding and areas for future development.
