“…Tournier et al (2003) demonstrated that SlERF2, an ERF that binds a GCC-box, plays an important role during the ripening of tomato. Similar patterns were observed for ERFs expressed during the ripening of different fruits (Xiao et al, 2013). The overexpression of LeERF1 shortens the fruit postharvest life (Li et al, 2007), while LeERF2 modulates ethylene biosynthesis in tomato and tobacco.…”

ABSTRACT. Sweet orange (Citrus sinensis) plays an important role in the economy of more than 140 countries, but it is grown in areas with intermittent stressful soil and climatic conditions. The stress tolerance could be addressed by manipulating the ethylene response factor (ERF) transcription factors because they orchestrate plant responses to environmental stress. We performed an in silico study on the ERFs in the expressed sequence tag database of C. sinensis to identify potential genes that regulate plant responses to stress. We identified 108 putative genes encoding protein sequences of the AP2/ERF superfamily distributed within 10 groups of amino acid sequences. Ninety-one genes were assembled from the ERF family containing only one AP2/ ERF domain, 13 genes were assembled from the AP2 family containing two AP2/ERF domains, and four other genes were assembled from the RAV family containing one AP2/ERF domain and a B3 domain. Some conserved domains of the ERF family genes were disrupted into a few segments by introns. This irregular distribution of genes in the AP2/ ERF superfamily in different plant species could be a result of genomic losses or duplication events in a common ancestor. The in silico gene expression revealed that 67% of AP2/ERF genes are expressed in tissues with usual plant development, and 14% were expressed in stressed tissues. Because the AP2/ERF superfamily is expressed in an orchestrated way, it is possible that the manipulation of only one gene may result in changes in the whole plant function, which could result in more tolerant crops.

“…S1). Furthermore, we also demonstrated that GST-MaERF11-N proteins could bind to the regions including the GCC-box in the promoters of MaEXP2, MaEXP7, and MaEXP8, as well as an ethylene biosynthetic gene MaACO1, which has been identified in our previous study (Xiao et al, 2013; Fig. 2D; Supplemental Fig.…”

“…In a previous study, sequence analysis displayed that MaERF11 includes the EAR motif, a repression domain, implying that MaERF11 might act as a transcriptional repressor (Xiao et al, 2013). To examine whether MaERF11 possesses transcriptional repression activity, the VP16 transcriptional activation domain was used as a positive control and the full-length cDNA of MaERF11 fused with VP16 was used as an effector, and the respective constructs were expressed in tobacco (Nicotiana tabacum cv Bright Yellow 2) BY2 protoplasts (Fig.…”

“…Hence, gaining insights into the molecular mechanisms underlying banana fruit ripening will help develop effective post-harvest technologies to extend the shelf life and improve the quality of this fruit. Our previous study had indicated that the EAR-containing MaERF11 was down-regulated in peel and pulp of banana fruit during ripening or after treatment with ethylene, and bound to and suppressed MaACS1 and MaACO1 promoters (Xiao et al, 2013). However, the transcriptional regulatory mechanism underlying MaERF11 in fruit ripening remains poorly understood.…”

Banana Transcription Factor MaERF11 Recruits Histone Deacetylase MaHDA1 and Represses the Expression of MaACO1 and Expansins during Fruit Ripening

et al. 2016

Phytohormone ethylene controls diverse developmental and physiological processes such as fruit ripening via modulation of ethylene signaling pathway. Our previous study identified that ETHYLENE RESPONSE FACTOR11 (MaERF11), a transcription factor in the ethylene signaling pathway, negatively regulates the ripening of banana, but the mechanism for the MaERF11-mediated transcriptional regulation remains largely unknown. Here we showed that MaERF11 has intrinsic transcriptional repression activity in planta. Electrophoretic mobility shift assay and chromatin immunoprecipitation analyses demonstrated that MaERF11 binds to promoters of three ripening-related Expansin genes, MaEXP2, MaEXP7 and MaEXP8, as well as an ethylene biosynthetic gene MaACO1, via the GCC-box motif. Furthermore, expression patterns of MaACO1, MaEXP2, MaEXP7, and MaEXP8 genes are correlated with the changes of histone H3 and H4 acetylation level during fruit ripening. Moreover, we found that MaERF11 physically interacts with a histone deacetylase, MaHDA1, which has histone deacetylase activity, and the interaction significantly strengthens the MaERF11-mediated transcriptional repression of MaACO1 and Expansins. Taken together, these findings suggest that MaERF11 may recruit MaHDA1 to its target genes and repress their expression via histone deacetylation.

“…Banana ripening is an irreversible process, characterized by a climacteric respiratory pattern, which is stimulated by an autocatalytic production of ethylene and physiological and metabolic changes that are sensitive to temperature and ethylene itself (XIAO et al, 2013). Several studies have been conducted on control postharvest banana quality, discussing storage conditions and treatments to prolong its shelf life (FERNANDES et al, 2010;WANG et al, 2014;ZHANG et al, 2010).…”

-The objective of this work was to evaluate the tolerance of fruits of different banana cultivars to low temperature storages. Fruits of the cultivars Nanicão (AAA), Prata (AAB), Vitória (AAAB), Maçã (AAB) and Caipira (AAA) were used. Clusters of three fruits were kept in cold storage for 7, 14 and 21 days, with average temperature of 10.53±0.37°C and relative humidity of 85%. Subsequently, the clusters were transferred to temperatures of 22±0.39°C and evaluated for 16 days. The fruits of all cultivars remained green after 21 days of storage at 10.53±0.37°C. Fruits of the cultivar Nanicão did not completely ripened after transferred to the 22°C storage, when stored for 7 days at low temperature. These fruits were firmer, with green peel and low soluble solids and titratable acidity. The fruits of all cultivars complete the ripening when transferred to room temperature after 21 days of cold storage. Chilling injuries increased with cold storage time in all cultivars. The cultivars Nanicão, Caipira and Maçã had more symptoms of chilling injury, while Prata and Vitória were more tolerant to the cold storage (10.53°C) for up to 21 days, showing normal ripening after transferred to the 22±0.39°C storage.Keywords: Musa spp. Chilling injury.

TOLERÂNCIA AO FRIO DE FRUTOS DE DIFERENTES CULTIVARES DE BANANEIRASRESUMO -O objetivo deste trabalho foi avaliar a tolerância dos frutos de diferentes cultivares de bananeira a baixa temperatura de armazenamento. Foram utilizados frutos das bananas Nanicão (AAA), Prata (AAB), Vitória (AAAB), Maçã (AAB) e Caipira (AAA). Utilizaram-se buquês com três frutos, mantidos em câmara fria por 7, 14 e 21 dias, com temperatura média de 10,53±0,37°C e umidade relativa do ar de 85%. Posteriormente, os buquês foram transferidos para a temperatura de 22±0,39°C e avaliados por 16 dias. Os frutos dos cultivares estudados peraneceram verdes após 21 dias de armazenamento a 10,53±0,37°C. Frutos do Nanicão não completaram o amadurecimento após serem transferidos para a temperatura de 22°C, quando armazenados por 7 dias à baixa temperatura, apresentando frutos mais firmes, com casca verde, baixos teores de sólidos solúveis e acidez titulável. Após 21 dias de armazenamento refrigerado, os frutos de todos os cultivares completaram o amadurecimento, depois de transferidos para temperatura ambiente. Os danos por frio aumentaram com o avanço do tempo de armazenamento refrigerado, para todos os cultivares. Nanicão, Caipira e Maçã apresentaram sintomas mais evidentes de dano por frio. As bananas Prata e Vitória mostraram-se mais tolerantes ao armazenamento refrigerado na temperatura de 10,53°C por até 21 dias, exibindo amadurecimento normal após a transferência para a temperatura de 22°C.Palavras-chave: Musa spp. Injúria por frio.
