“…The AP2/ERF family is a class of transcription factors found mainly in plants. At least one AP2 domain is typically contained within members of the AP2/ERF family [19]; this encodes a domain consisting of 60-70 amino acids [20]. Direct interaction with cis-acting elements, such as the dehydration response element (DRE)/C-repeat element (CRT) and/or the GCC box located within the promoter region of target genes, can be facilitated by these AP2/ERF proteins [21,22].…”

Background: Bayberry is the most economically significant fruit within the Myricaceae family, having high nutritional and medicinal value. The AP2/ERF family is a class of transcription factors found mainly in plants. However, the bayberry AP2/ERF gene family has not previously been studied. Results: In this study, 113 members of the bayberry AP2/ERF gene family were identified. According to the phylogenetic tree, the members of this group are divided into three subfamilies. The gene structure and conserved motifs were analyzed. Chromosome localization showed that 95 genes were unevenly distributed on 8 chromosomes and 18 genes were located on the skeleton. In addition, we further investigated the collinearity between these genes and related genes in six other species. Transcriptomic data showed that the expression pattern of AP2/ERFgene was different in bayberry space electric field treatment and at different stages of development. Conclusions: The AP2/ERFgene was identified in the genome of bayberry, and its structure, conserved motif, and phylogenetic relationship were analyzed. These findings of this study serve as a reference for the genome-wide identification of the AP2/ERFgene family in other species and groundwork for future research on the function of AP2/ERF genes in bayberry.

“…We identified two genes encoding AP2/ERF (Prupe.2G220100 and Prupe.1G037700) domain-containing proteins in the turquoise module ( Figure 4D, F ). The AP2/ERF TFs have been reported to play a regulatory role in plants in response to abiotic stress ( Xie et al., 2022 ; Yu et al., 2022 ). Overexpression of TERF2/LeERF2 TF in tomato and tobacco significantly increased their cold tolerance capacity ( Zhang and Huang, 2010 ).…”

Low temperature is one of the environmental factors that restrict the growth and geographical distribution of peach (Prunus persica L. Batsch). To explore the molecular mechanisms of peach brunches in response to cold, we analyzed the metabolomics and transcriptomics of ‘Donghe No.1’ (cold-tolerant, CT) and ‘21st Century’ (cold-sensitive, CS) treated by different temperatures (-5 to -30°C) for 12 h. Some cold-responsive metabolites (e.g., saccharides, phenolic acids and flavones) were identified with upregulation only in CT. Further, we identified 1991 cold tolerance associated genes in these samples and they were significantly enriched in the pathways of ‘galactose metabolism’, ‘phenylpropanoid biosynthesis’ and ‘flavonoids biosynthesis’. Weighted gene correlation network analysis showed that soluble sugar, flavone, and lignin biosynthetic associated genes might play a key role in the cold tolerance of peach. In addition, several key genes (e.g., COMT, CCR, CAD, PER and F3’H) were substantially expressed more in CT than CS under cold stress, indicating that they might be major factors during the adaptation of peach to low temperature. This study will not only improve our understanding towards the molecular mechanisms of peach trees under cold stress but also contribute to the screening and breeding program of peach in the future.

“…Previous studies have shown that ERF proteins enhance resistance to various abiotic stresses, including drought [ 56 ], salt [ 57 ], cold [ 58 ], and fungal disease [ 59 ]. However, there are few studies on the involvement of ERF genes in the root system’s response to abiotic stresses.…”

Roots are the main organ for water uptake and the earliest part of a plant’s response to drought, making them of great importance to our understanding of the root system’s response to drought. However, little is known about the underlying molecular mechanisms that control root responses to drought stress. Here, we identified and functionally characterized the AP2/ERF family transcription factor (TF) PtrABR1 and the upstream target gene zinc-finger protein TF PtrYY1, which respond to drought stress by promoting the growth and development of lateral roots in Populus trichocarpa. A root-specific induction of PtrABR1 under drought stress was explored. The overexpression of PtrABR1 (PtrABR1-OE) promoted root growth and development, thereby increasing tolerance to drought stress. In addition, PtrYY1 is directly bound to the promoter of PtrABR1 under drought stress, and the overexpression of PtrYY1 (PtrYY1-OE) promoted lateral root growth and development and increased tolerance to drought stress. An RNA-seq analysis of PtrABR1-OE with wild-type (WT) poplar identified PtrGH3.6 and PtrPP2C44, which share the same pattern of expression changes as PtrABR1. A qRT-PCR and cis-element analysis further suggested that PtrGH3.6 and PtrPP2C44 may act as potential downstream targets of PtrABR1 genes in the root response pathway to drought stress. In conclusion, these results reveal a novel drought regulatory pathway in which PtrABR1 regulates the network through the upstream target gene PtrYY1 and the potential downstream target genes PtrGH3.6 and PtrPP2C44, thereby promoting root growth and development and improving tolerance to drought stress.
