“…Not only is its expression strongly induced following wounding and coincides with callus formation at the cut sites, but a further prominent feature observed for ERF114 overexpression plants is neoplasia in the form of tissue that is similar to green callus, and it is often produced at wound sites. Moreover, it has been observed that explants which overexpress ERF114 increase their rates of callus production when cultured on callus-inducing medium (Mehrnia et al, 2013). Taken together, the data indicate that ERF114 might play a role in wound healing through control of the ratio between auxin and cytokinin, which is known to be important for control of apical dominance and callus formation (Fig.…”

“…ERF114 is also known as ERF BUD ENHANCER (EBE) because of the observed axillary bud outgrowth upon its overexpression. Similar to ERF113, ERF114 activity has been linked with tissue regeneration (Mehrnia et al, 2013). Not only is its expression strongly induced following wounding and coincides with callus formation at the cut sites, but a further prominent feature observed for ERF114 overexpression plants is neoplasia in the form of tissue that is similar to green callus, and it is often produced at wound sites.…”

Emerging role of the plant ERF transcription factors in coordinating wound defense responses and repair

Plants react to wounding through the activation of both defense and repair pathways, but how these two responses are coordinated is unclear. Here, we put forward the hypothesis that diverse members of the subfamily X of the plant-specific ethylene response factor (ERF) transcription factors coordinate stress signaling with the activation of wound repair mechanisms. Moreover, we highlight the observation that tissue repair is strongly boosted through the formation of a heterodimeric protein complex that comprises ERF and transcription factors of the GRAS domain type. This interaction turns ERFs into highly potent and stress-responsive activators of cell proliferation. The potency to induce stem cell identity suggests that these heterodimeric transcription factor complexes could become valuable tools to increase crop regeneration and transformation efficiency.

The prevention of Botrytis cinerea infection and the study of grape seedlessness are very important for grape industries. Finding correlated regulatory genes is an important approach towards understanding their molecular mechanisms.• Ethylene responsive factor (ERF) gene family play critical roles in defence networks and the growth of plants. To date, no large-scale study of the ERF proteins associated with pathogen defence and ovule development has been performed in grape (Vitis vinifera L.). In the present study, we identified 113 ERF genes (VvERF) and named them based on their chromosome locations. The ERF genes could be divided into 11 groups based on a multiple sequence alignment and a phylogenetic comparison with homologues from Arabidopsis thaliana. Synteny analysis and Ka/Ks ratio calculation suggested that segmental and tandem duplications contributed to the expansion of the ERF gene family. The evolutionary relationships between the VvERF genes were investigated by exon-intron structure characterisation, and an analysis of the cis-acting regulatory elements in their promoters suggested potential regulation after stress or hormone treatments.• Expression profiling after infection with the fungus, B. cinerea, indicated that ERF genes function in responses to pathogen attack. In addition, the expression levels of most ERF genes were much higher during ovule development in seedless grapes, suggesting a role in ovule abortion related to seedlessness.• Taken together, these results indicate that VvERF proteins are involved in responses to Botrytis cinerea infection and in grape ovule development. This information may help guide strategies to improve grape production.

“…The chrysanthemum ERF transcription factor CmERF053 has been shown to regulate shoot branching [46], while the product of the Larix kaempferi AP2/ERF gene LkAP2L2 exerts a pleiotropic effect on both branching and seed development [47]. The A. thaliana gene EBE encodes an AP2/ERF transcription factor, which has a notable effect on shoot architecture [48]. Finally, the peach transcription factor PpERF3b promotes precocious side-branching [49].…”

Background: Producers of cut flower chrysanthemum are obliged to manually remove lateral buds, a procedure which consumes one third of the total production cost. The formation of lateral buds in 'SEI NO ISSEI' is suppressed when the plants are exposed to high temperatures, but the molecular basis of this phenomenon is not well understood. Here, the transcriptome of buds formed by decapitated chrysanthemum plants grown under a high temperature regime was characterized with a view to revealing which genes known to be involved in a pathway determining shoot branching were induced/repressed by the treatment. Results: The transcriptomic data was acquired using RNA-Seq technology, based on the Illumina HiSeq™ 2000 platform. Four libraries were generated from pooled lateral buds of decapitated 'SEI NO ISSEI'. To predict the potential functions of unigenes in the 'SEI NO ISSEI' buds, after assembly, we performed seven functional database annotations. 132,396 unigenes were assembled, of which 79,116 unigenes were annotated in the seven functional databases. The percentage of unigenes annotated in the NR, NT, Swiss-Prot, KEGG, COG, Interpro, and GO databases were 54.59%, 42.96%, 39.05%, 41.84%, 20.72%, 37.25%, and 13.01%, respectively. Multiple differentially expressed transcription factors and auxin-related genes were identified in buds of decapitated 'SEI NO ISSEI' under 28°C/23°C or 38°C/33°C. Constitutively expressing CmERF110 in wild type Arabidopsis thaliana produced a bushy plant. A quantitative analysis of gene expression changes in the CmERF110 transgenic A. thaliana plants showed that the presence of the transgene altered the abundance of transcript produced by TIR1, ARF2, ARF16, IAA3 and IAA9 (encoding auxin signaling proteins) and PIN1, AUX1, LAX1, LAX2 and ABCB1 (auxin transport). Conclusions: This study reported a highly complete transcriptome from the buds of decapitated 'SEI NO ISSEI'. Differential abundant transcripts during high temperature treatments were identified and validated by qPCR, many of these differentially abundant transcripts as key players in bud outgrowth. These include known members of the AP2/ERF, MYB, WRKY, bHLH families and auxin-related genes. CmERF110 regulated shoot branching when its encoding gene was heterologously expressed in A. Thaliana. The regulation acted through the auxin-related genes. Background 4 The ability of the plant shoot to form branches has a major effect on the plant's architecture, a trait of major importance in the context of crop domestication and improvement [1, 2]. Axillary meristems are composed of a group of cells which have retained their meristematic potential [3]. Following their initiation, these structures develop into axillary buds, which either remain dormant or develop into a new branches, depending a number of both internal and/or external cues [4]. Three forms of bud dormancy have been recognized: paradormancy occurs when growth ceases because of physiological factors external to the bud; endodormacy when growth is regulated by internal physiologi...
