“…For example, the AP2/ERF factor, NtORC1, interacts with NtbHLH and commonly regulates the expression of genes containing G-box and GCC motifs in their promoter regions ( De Boer et al, 2011 ). A transcriptional repressor recently identified in banana fruit, MaERF10, interacts with MaJAZ3 proteins to enforce the repression of jasmonate (JA) biosynthesis-related genes involved in MeJA-mediated cold tolerance ( Qi et al, 2016 ). In the present study, GmbHLH was found to interact with GmERF113 using yeast two-hybrid and BiFC assays.…”

Phytophthora root and stem rot of soybean caused by the oomycete Phytophthora sojae, is a destructive disease worldwide. Ethylene response factors (ERFs) play important roles in regulating plant biotic and abiotic stress tolerance. In this study, a new ERF gene, GmERF113, was isolated from the highly resistant soybean ‘Suinong 10.’ Sequence analysis suggested that the protein encoded by GmERF113 contained a conserved AP2/ERF domain of 58 amino acid and belonged to the B-4 subgroup of the ERF subfamily. Expression of GmERF113 was significantly induced by P. sojae, ethylene, and methyl jasmonate. GmERF113 protein localized to the nucleus when transiently expressed in Arabidopsis protoplasts, could bind to the GCC-box, and acted as a transcription activator. In addition, a region of the full-length GmERF113, GmERF113-II, interacted with a basic helix-loop-helix transcription factor (GmbHLH) in yeast cells. Full-length GmERF113 also interacted with GmbHLH in planta. GmERF113-overexpressing transgenic plants in susceptible cultivar ‘Dongnong 50’ soybean exhibited increased resistance to P. sojae and positively regulated the expression of the pathogenesis-related genes, PR1 and PR10-1. These results indicate that GmERF113 may play a crucial role in the defense of soybean against P. sojae infection.

“…Other critical components of ethylene signaling, especially ERF TFs, have been well documented to function in various stress responses. Preliminary studies conducted to clarify the ERF TF functions related to cold stress responses examined the cold signal modulators CsERF1, AtERF105, and MaERF10 in tobacco (Nicotiana benthamiana) (Ma et al, 2014), A. thaliana (Bolt et al, 2017), and banana (Qi et al, 2016), respectively. Furthermore, the modulation of cold tolerance by several ERF TFs depends on the ethylene signaling-mediated cold response pathway.…”

Ethylene increases the cold tolerance of apple via the MdERF1B–MdCIbHLH1 regulatory module

Cold stress has always been a major abiotic factor affecting the yield and quality of temperate fruit crops. Ethylene plays a critical regulatory role in the cold stress response, but the underlying molecular mechanisms remain elusive. Here, we revealed that ethylene positively modulates apple responses to cold stress. Treatment with 1-aminocyclopropane-1-carboxylate (an ethylene precursor) and aminoethoxyvinylglycine (an ethylene biosynthesis inhibitor) respectively increased and decreased the cold tolerance of apple seedlings. Consistent with the positive effects of ethylene on cold stress responses, a low-temperature treatment rapidly induced ethylene release and the expression of MdERF1B, which encodes an ethylene signaling activator, in apple seedlings. Overexpression of MdERF1B significantly increased the cold tolerance of apple plant materials (seedlings and calli) and Arabidopsis thaliana seedlings. A quantitative realtime PCR analysis indicated that MdERF1B upregulates the expression of the cold-responsive gene MdCBF1 in apple seedlings. Moreover, MdCIbHLH1, which functions upstream of CBF-dependent pathways, enhanced the binding of MdERF1B to target gene promoters as well as the consequent transcriptional activation. The stability of MdERF1B-MdCIbHLH1 was affected by cold stress and ethylene. Furthermore, MdERF1B interacted with the promoters of two genes critical for ethylene biosynthesis, MdACO1 and MdERF3. The resulting upregulated expression of these genes promoted ethylene production. However, the downregulated MdCIbHLH1 expression in MdERF1B-overexpressing apple calli significantly inhibited ethylene production. These findings imply that MdERF1B-MdCIbHLH1 is a potential regulatory module that integrates the cold and ethylene signaling pathways in apple.

Pepper (Capsicum annuum L.) fruit is sensitive to temperatures below 10 °C, which severely diminish fruit quality during cold chain distribution. Seed browning was a major chilling symptom in 36 genotypes of C. annuum fruit screened after storage at 2 °C for 3 weeks. Among them, pepper fruits of chilling-insensitive ‘UZB-GJG-1999–51’ and -sensitive ‘C00562’ were treated at 2 °C for 0 or 24 h, respectively. Analyses of integrated transcriptome-metabolome and relative gene expression in seeds obtained from the two genotypes were conducted to identify key factors involved in the seed browning induced by chilling. The relative contents of branched-chain amino acids such as leucine, isoleucine, and valine were significantly increased after chilling. Transcriptome identification showed 3,140 differentially expressed genes (log twofold change > 1.0 and FDR-corrected p value < 0.05) affected by chilling between the two genotypes. Particularly, genes related to jasmonic acid synthesis and signaling were differentially expressed. A regulatory network of jasmonic acid synthesis and signaling, and regulation of ERF family genes might contribute to chilling response in pepper fruit. The results of this study may help facilitate further studies to develop chilling-insensitive peppers and could be a basis for improving postharvest fruit quality.
