“…The AP2/ERF family of transcription factors play a crucial role in various aspects of plant physiology, such as growth, development, responses to stress, and the production of secondary metabolites such as flavonoids, anthocyanins, and alkaloids [ 33–39 ]. In grape, it has been proven that VvERF63 positively regulates the cold tolerance of leaves [ 40 ]. VvERF17 and VvERF75 regulate chlorophyll degradation by activating chlorophyll catabolic genes [ 41 , 42 ].…”

Terpenoids are important contributors to the aroma of grapes and wines. Grapes contain terpenoids in both volatile free form and non-volatile glycosidic form, with the latter being more abundant. Glycosylated terpenoids are deemed as latent aromatic potentials for their essential role in adding to the flowery and fruity bouquet of wines. However, transcriptional regulatory mechanism underlying glycosylated terpenoid biosynthesis remains poorly understood. Our prior study identified an AP2/ERF transcription factor, VviERF003, through DNA pull-down screening using the promoter of terpenoid glycosyltransferase VviGT14 gene. This study demonstrated that both genes were co-expressed and synchronized with the accumulation of glycosylated monoterpenoids during grape maturation. VviERF003 can bind to the VviGT14 promoter and promote its activity according to yeast one-hybrid and dual-luciferase assays. VviERF003 upregulated VviGT14 expression in vivo, leading to increased production of glycosylated monoterpenoids based on the evidence from overexpression or RNA interference in leaves, berry skins, and calli of grapes, as well as tomato fruits. Additionally, VviERF003 and VviGT14 expressions and glycosylated monoterpenoid levels were induced by ethylene in grapes. The findings suggest that VviERF003 is ethylene-responsive and stimulates glycosylated monoterpenoid biosynthesis through upregulating VviGT14 expression.

Background AP2/ERF transcription factors (TFs) are plant-specific transcription factors involved in the regulation of plant growth and development and in response to stresses. Although AP2/ERF TFs have been identified in numerous species and analyzed in many, such as Oryza sativa, Arabidopsis thaliana, and Populus trichocarpa, studies on the Prunus sibirica AP2/ERF (PsAP2/ERF) gene family have not been reported. In the study, 112 PsAP2/ERFs were identified and categorized into 16 subfamilies. Results The same subfamilies of PsAP2/ERFs typically exhibited similar exon-intron structures and motif compositions. In all, 50 pairs of segmentally duplicated genes were identified within the PsAP2/ERF gene family. The results showed that 20 PsAP2/ERFswere highly expressed in leaves, roots, and pistils, and highly expressed under different conditions of low temperature stress. Conclusions This study provides a solid scientific foundation for follow-up research on the evolutionary characteristics of AP2/ERFs in P. sibirica, leading to an improved understanding of the molecular basis of their developmental and low-temperature stress responses, and further investigating the functional expression of PsAP2/ERFs.

“…The ethylene response factor (ERF) subfamily of TFs plays an important role in low-temperature stress in plants. Li et al overexpressed VvERF63 in Arabidopsis thaliana, which resulted in improved cold tolerance in Arabidopsis thaliana at the seedling and maturity stages, thus suggesting that VvERF63 is positively involved in cold response [45]; ERF105 is a cold-regulated TF gene in Arabidopsis thaliana, and overexpressed plants were more frost-tolerant [46]. Furthermore, Wu et al found that JERF3 enhanced tolerance to cold stress in tobacco through the transcriptional activation of gene expression, leading to the reduced accumulation of reactive oxygen species [47].…”

Quinoa is a nutritious crop that is tolerant to extreme environmental conditions; however, low-temperature stress can affect quinoa growth, development, and quality. Considering the lack of molecular research on quinoa seedlings under low-temperature stress, we utilized a Weighted Gene Co-Expression Network Analysis to construct weighted gene co-expression networks associated with physiological indices and metabolites related to low-temperature stress resistance based on transcriptomic data. We screened 11 co-expression modules closely related to low-temperature stress resistance and selected 12 core genes from the two modules that showed the highest associations with the target traits. Following the functional annotation of these genes to determine the key biological processes and metabolic pathways involved in low-temperature stress, we identified four important transcription factors involved in resistance to low-temperature stress: gene-LOC110731664, gene-LOC110736639, gene-LOC110684437, and gene-LOC110720903. These results provide insights into the molecular genetic mechanism of quinoa under low-temperature stress and can be used to breed lines with tolerance to low-temperature stress.
