“…As AP2/ERF transcription factors, OsDREB1C and NGR5 increased rice nitrogen use efficiency. OsDREB1C can simultaneously improve the photosynthetic efficiency and nitrogen use efficiency of rice, leading to early heading, high yield and early maturity, thereby increasing rice yield [ 47 ]. Over-expression of OsDREB1C enhances the ability of nitrogen uptake and transport, which allocates more nitrogen to grains, thereby increasing the nitrogen utilization efficiency by at least 25%.…”

APETALA2/ethylene response factor (AP2/ERF) is widely found in the plant kingdom and plays crucial roles in transcriptional regulation and defense response of plant growth and development. Based on the research progress related to AP2/ERF genes, this paper focuses on the classification and structural features of AP2/ERF transcription factors, reviews the roles of rice AP2/ERF genes in the regulation of growth, development and stress responses, and discusses rice breeding potential and challenges. Taken together; studies of rice AP2/ERF genes may help to elucidate and enrich the multiple molecular mechanisms of how AP2/ERF genes regulate spikelet determinacy and floral organ development, flowering time, grain size and quality, embryogenesis, root development, hormone balance, nutrient use efficiency, and biotic and abiotic response processes. This will contribute to breeding excellent rice varieties with high yield and high resistance in a green, organic manner.

“…It has been identified in rice that an OsDREB1C can drive a transcription program with diverse functions, determining photosynthetic capacity, nitrogen utilization, and flowering time. The yield of rice overexpressing OsDREB1C has increased by 41.3%~68.3% [ 53 ]. In this study, we preliminarily explored the relative expression levels of 13 representative PdAP2/ERF genes in four tissues of ‘Wanfeng’ almond and six freezing stress temperature treatments in annual dormant branches based on qRT–PCR technology.…”

The AP2/ERF transcription factor family is one of the largest transcription factor families in plants and plays an important role in regulating plant growth and development and the response to biotic and abiotic stresses. However, there is no report on the AP2/ERF gene family in almond (Prunus dulcis). In this study, a total of 136 PdAP2/ERF genes were identified from the almond genome, and their protein physicochemical properties were analyzed. The PdAP2/ERF members were divided into five subgroups: AP2, RAV, ERF, DREB, and Soloist. The PdAP2/ERF members in each subgroup had conserved motif types and exon/intron numbers. PdAP2/ERFS members are distributed on eight chromosomes, with 22 pairs of segmental duplications and 28 pairs of tandem duplications. We further explored the colinear relationship between almond and Arabidopsis thaliana, Oryza sativa, Malus domestica, and Prunus persica AP2/ERF genes and their evolution. The results of cis-acting elements showed that PdAP2/ERF members are widely involved in various processes, such as growth and development, hormone regulation, and stress response. The results based on transcriptome expression patterns showed that PdAP2/ERF genes had significant tissue-specific expression characteristics and were involved in the response of annual dormant branches of almond to low-temperature freezing stress. In addition, the fluorescence quantitative relative expression results of 13 representative PdAP2/ERF genes in four tissues of ‘Wanfeng’ almond and under six low-temperature freezing treatments of annual dormant branches were consistent with the transcriptome results. It is worth noting that the fluorescence quantitative expression level showed that the PdERF24 gene was extremely significant at −30 °C, suggesting that this gene may play an important role in the response of almond dormancy to ultralow temperature freezing stress. Finally, we identified 7424 and 6971 target genes based on AP2 and ERF/DREB DNA-binding sites, respectively. The GO and KEGG enrichment results showed that these target genes play important roles in protein function and multiple pathways. In summary, we conducted bioinformatics and expression pattern studies on PdAP2/ERF genes, including 13 PdAP2/ERF genes, and performed fluorescence quantitative analysis of annual dormant shoots under different low-temperature freezing stress treatments to understand the tolerance of almond dormancy to freezing stress and suggest future improvements.

“…ERF TFs, the last step of the ethylene signaling pathway, regulate the response of plants to environmental changes (Xie et al, 2019). Recently, one intronless ERF TF was reported to simultaneously modulate photosynthesis and nitrogen utilization in rice (Wei et al, 2022). ERF TFs showed remarkable changes to low CO 2 stress in all five Flaveria species (Supplemental Note 15).…”

The genus Flaveria, containing species at different evolutionary stages of the progression from C3 to C4 photosynthesis, is used as a model system to study the evolution of C4 photosynthesis. Here, we report chromosome-scale genome sequences for five Flaveria species, including C3, C4, and intermediate species. Our analyses revealed that both acquiring additional gene copies and recruiting ethylene responsive factor (ERF) cis-regulatory elements (CREs) contributed to the emergence of C4 photosynthesis. ERF transcriptional factors (TFs), especially intronless ERF TFs, were co-opted in dicotyledonous C4 species and monocotyledonous C4 species in parallel. These C4 species co-opted intronless ERF TFs originated from the Late Ordovician mass extinction that occurred ~450 million years ago in coping with environmental stress. Therefore, this study demonstrated that intronless ERF TFs were acquired during the early evolution of plants and provided the molecular toolbox facilitating multiple subsequent independent evolutions of C4 photosynthesis.
