“…Another vital role of ABA is the induction of stress-responsive genes. It activates a wide array of genes encoding proteins that bolster the antioxidant system, assist in osmotic adjustment, and synthesize heat-shock proteins for protection under heat stress ( Palchetti et al., 2021 ; Saidi et al., 2021 ). Lastly, ABA is involved in the regulation of seed dormancy and germination, allowing plants to synchronize their life cycle with environmental conditions.…”

Solanaceous vegetable crops are cultivated and consumed worldwide. However, they often confront diverse abiotic stresses that significantly impair their growth, yield, and overall quality. This review delves into melatonin and abscisic acid (ABA) biosynthesis and their roles in abiotic stress responses. It closely examines the intricate interplay between melatonin and ABA in managing stress within plants, revealing both collaborative and antagonistic effects and elucidating the underlying molecular mechanisms. Melatonin and ABA mutually influence each other’s synthesis, metabolism and that of other plant hormones, a key focus of this study. The study highlights melatonin’s role in aiding stress management through ABA-dependent pathways and key genes in the melatonin-ABA interaction. Specifically, melatonin downregulates ABA synthesis genes and upregulates catabolism genes, leading to reduced ABA levels. It also directly scavenges H2O2, enhancing antioxidant enzyme activities, thereby underscoring their collaborative role in mediating stress responses. Moreover, the interplay between melatonin and ABA plays an essential role in multiple physiological processes of plants, including stomatal behaviors, wax accumulation, delay leaf senescence, seed germination, and seedlings growth, among others. Recognizing these relationships in Solanaceae vegetable crops holds great importance for improving agricultural practices and crop quality. In summary, this review offers a comprehensive overview of recent studies on the melatonin and ABA interplay, serving as a valuable resource for researchers and breeders dedicated to fortifying crop resilience and productivity within challenging environments.

“…Moreover, two GATA genes identified in our study, StGATA11 and StGATA19 , did not show correspondence in the latter work (Yu, Chang, et al, 2021 ). Additionally, comparisons with another study by Saidi et al ( 2021 ) revealed a partial overlap of GATA members in potato. While the exon intron structure of the subgroups did not display consistent gene structure patterns (especially regarding the intron number), the number of exons (2) was highly consistent and conserved compared to the variable intron number (1–10).…”

“…An intriguing aspect is their potential involvement in the tissue‐specific expression of genes associated with abiotic stress networks. For instance, investigations have demonstrated tissue‐specific expression of GATA members in potato, particularly in roots, inflorescences, and shoots (Saidi et al, 2021 ), while in wheat, the emphasis has been on leaf‐specific expression (Du et al, 2022 ). Unfortunately, conducting in silico expression analysis was challenging due to the limited information available in the solArray Potato Microarray Database.…”

GATA is one of the prominent transcription factor families conserved among many organisms in eukaryotes and has different biological roles in many pathways, particularly in light regulation in plants. Although GATA transcription factors (TFs) have been identified in different crop species, their roles in abiotic stress tolerance have not been studied in potato. In this study, we identified 32 GATA TFs in potato (Solanum tuberosum) by in silico analyses, and expression levels of selected six genes were investigated in drought‐tolerant (Sante) and sensitive (Agria) cultivars under light, drought, and combined (light + drought) stress conditions. According to the phylogenetic results, StGATA TFs were divided into four main groups (I, II, III, and IV) and different sub‐groups in I and II (eight and five, respectively). StGATA genes were uniformly localized to each chromosome with a conserved exon/intron structure. The presence of cis‐elements within the StGATA family further supported the possible involvement in abiotic stress tolerance and light response, tissue‐specific expression, and hormonal regulation. Additional PPI investigations showed that these networks, especially for Groups I, II, and IV, play a significant role in response to light and drought stress. Six StGATAs were chosen from these groups for expressional profiling, and their expression in both Sante and Agria was mainly downregulated under purple and red lights, drought, and combined stress (blue + drought and purple + drought). The interactomes of selected StGATAs, StGATA3, StGATA24, and StGATA29 were analyzed, and the accessions with GATA motifs were checked for expression. The results showed that the target proteins, cyclin‐P3‐1, SPX domain‐containing protein 1, mitochondrial calcium uniporter protein 2, mitogen‐activated protein kinase kinase kinase YODA, and splicing factor 3 B subunit 4‐like, mainly play a role in phytochrome‐mediated stomatal patterning, development, and activity. Understanding the interactions between drought stress and the light response mechanisms in potato plants is essential. It will eventually be possible to enhance potato resilience to climate change by manipulating the TFs that play a role in these pathways.

“…For instance, in contrast to the reported conserved functions of many AGC kinases, INCOM-PLETE ROOT HAIR ELONGATION (IRE), a kinase of the "AGC other" group, seems to have acquired a new function in Medicago Truncatula Gaertn.. In Arabidopsis, IRE kinase has been revealed to control root hair elongation, while inMedicago a role in the formation of nodules has been indicated (Pislariu and Dickstein, 2007;Oyama et al, 2002;Saidi and Hajibarat, 2021a). Most of AGC kinase genes were located in the cytoplasm, but HvPDPK1, HvIREH1 and HvS6K2 genes were located in the mitochondria.…”

AGC kinases are highly conserved regulators in a variety of cellular processes such as differentiation, proliferation, and growth. They are known to play important roles in stress and hormonal responses, including ROS signaling. AGC kinases are the main class of protein kinases in plants, having central functions in different stages of plant growth. In the present study, the analysis of phylogenetic relationships, gene structures, chromosomal locations, synteny analysis, gene ontology, subcellular localization, and gene expression of AGC kinase identified 28 AGC kinase genes in barley. Phylogenetic tree grouped them into seven subfamilies, as supported by exon-intron organization. Gene duplication and synteny indicated that tandom and block duplication events played an essential role in the expansion of AGC kinase gene families in barley. The Real-time quantitative reverse transcription PCR (qRT-PCR) analysis performed for HvAGC kinase gene were largely expressed in different tissues of roots, stems, and leaves in Azaran and Jolgeh cultivars under heat and cold stresses. The results of chromosomal localization showed that the AGC kinases were located on all chromosomes of barley except chromosome 1. Genome evolution of species was surveyed using identification of orthologous and paralogous genes. Identifying overlaps between orthologous clusters can enable us to study the function and evolution of proteins in different species. To our knowledge, this is the first detailed report of using AGC kinases for bioinformatics analysis in barley. Results revealed a broad understanding of the AGC kinase gene family in barley, which will be valuable for improving barley varieties’ response to heat and cold stresses. Also, HvNDR6.2 gene can utilized as molecular markers under cold stress in the three organs.
