“…Transcription factors are able to regulate gene expression at the transcriptional level. In Arabidopsis , the WRKY53 transcription factor can regulate leaf senescence progression by inhibiting the expression level of the SENRK1 gene [ 51 ]. AhbHLH121 improves salt tolerance in the peanut by activating the expression of AhPOD , AhCAT , and AhSOD [ 52 ].…”

SPL (SQUAMOSA promoter binding protein-like), as one family of plant transcription factors, plays an important function in plant growth and development and in response to environmental stresses. Despite SPL gene families having been identified in various plant species, the understanding of this gene family in peanuts remains insufficient. In this study, thirty-eight genes (AhSPL1-AhSPL38) were identified and classified into seven groups based on a phylogenetic analysis. In addition, a thorough analysis indicated that the AhSPL genes experienced segmental duplications. The analysis of the gene structure and protein motif patterns revealed similarities in the structure of exons and introns, as well as the organization of the motifs within the same group, thereby providing additional support to the conclusions drawn from the phylogenetic analysis. The analysis of the regulatory elements and RNA-seq data suggested that the AhSPL genes might be widely involved in peanut growth and development, as well as in response to environmental stresses. Furthermore, the expression of some AhSPL genes, including AhSPL5, AhSPL16, AhSPL25, and AhSPL36, were induced by drought and salt stresses. Notably, the expression of the AhSPL genes might potentially be regulated by regulatory factors with distinct functionalities, such as transcription factors ERF, WRKY, MYB, and Dof, and microRNAs, like ahy-miR156. Notably, the overexpression of AhSPL5 can enhance salt tolerance in transgenic Arabidopsis by enhancing its ROS-scavenging capability and positively regulating the expression of stress-responsive genes. These results provide insight into the evolutionary origin of plant SPL genes and how they enhance plant tolerance to salt stress.

“…For example, the transcription factor was found to enhance plant stress resistance by regulating the gibberellin, jasmonic acid, and salicylic acid signaling pathways [ 33 , 34 , 35 ]. And WRKY53 has been reported to regulate plant growth and development, such as regulating the early and middle development of Arabidopsis leaves [ 36 ], leaf senescence [ 37 , 38 ] and so on. It can be seen that the WRKY53 transcription factor is widely studied in Arabidopsis thaliana , and the current research has not yet involved thermal response and response to ethylene signaling pathways.…”

The RNA-Seq and gene expression data of mature leaves under high temperature stress of Paeonia suffruticosa ‘Hu Hong’ were used to explore the key genes of heat tolerance of peony. The weighted gene co-expression network analysis (WGCNA) method was used to construct the network, and the main modules and core genes of co-expression were screened according to the results of gene expression and module function enrichment analysis. According to the correlation of gene expression, the network was divided into 19 modules. By analyzing the expression patterns of each module gene, Blue, Salmon and Yellow were identified as the key modules of peony heat response related functions. GO and KEGG functional enrichment analysis was performed on the genes in the three modules and a network diagram was constructed. Based on this, two key genes PsWRKY53 (TRINITY_DN60998_c1_g2, TRINITY_DN71537_c0_g1) and PsHsfB2b (TRINITY_DN56794_c0_g1) were excavated, which may play a key role in the heat shock response of peony. The three co-expression modules and two key genes were helpful to further elucidate the heat resistance mechanism of P. suffruticosa ‘Hu Hong’.

“…At the transcriptional level, the expression of almost all genes is regulated by transcription factors in plant biological processes. WRKY53 transcription factors promote leaf senescence by repressing SENRK1 gene expression [51]. Overexpression of ZmERF21 could improve drought resistance in maize seedlings by directly regulating stress-responsive genes [52].…”

Dephosphorylation is one of the important mechanisms regulating signal transduction in plant growth and development and in response to abiotic stresses. Type-one protein phosphatases (TOPPs) catalyze a significant number of important dephosphorylation events in cells, and play essential roles in plant developmental regulations and multiple stress responses. Nevertheless, the knowledge regarding the peanut’s TOPP gene family remains extremely restricted. Thirteen TOPP genes (AhTOPP1-13) were discovered in the peanut genome database through the utilization of HMMER and BLASTP methods in this research. The thirteen AhTOPP genes were classed into three clades together with their Arabidopsis homologs based on phylogenetic tree, and mapped on nine of twenty chromosomes. The examination of gene compositions and protein patterns indicated resemblance in the structure of exons and introns, as well as the arrangement of motifs within the identical clade, which further reinforces the findings of phylogenetic analysis. All AhTOPP proteins possessed STPPase_N, Metallophos domains, and the core catalytic sites. Promoter analysis showed that the AhTOPP genes may be widely involved in peanut development, hormones, and stress response. The RNA-seq data revealed the presence of AhTOPP genes in twenty-two tissues, suggesting potential variations in the functionality of AhTOPP genes. Furthermore, drought and salt stresses induced the expression of multiple AhTOPP genes, including AhTOPP1, AhTOPP4, AhTOPP7, AhTOPP9, and AhTOPP13. It is worth mentioning that the AhTOPP genes’ expression could potentially be controlled by various transcription factors with different functions, including ERF, WRKY, MYB, and Dof. We will conduct specific functional studies on the peanut TOPP genes through transgenics in future research.
