Effect of 1-methylcyclopropene (1-MCP) and ozone (Ο 3 ) post-harvest treatments on the proteomic profiling of Granny Smith apple peel (Malus x domestica Borkh) after cold storage

ABSTRACT: Superficial scald is a major physiological disorder in apple fruit that is induced by cold storage and is mainly expressed as brown necrotic patches on peel tissue. However, a global view of the gene-protein-metabolite interactome underlying scald prevention/sensitivity is currently missing. Herein, we have found for the first time that cold storage in an atmosphere enriched with ozone (O3) induced scald symptoms in ‘Granny Smith’ apple fruits during subsequent ripening at room temperature. In contrast, treatment with the ethylene perception inhibitor 1-methylcyclopropene (1-MCP) reversed this O3-induced scald effect. Amino acids, including branched-chain amino acids, were the most strongly induced metabolites in peel tissue of 1-MCP treated fruits. Proteins involved in oxidative stress and protein trafficking were differentially accumulated prior to and during scald development. Genes involved in photosynthesis, flavonoid biosynthesis and ethylene signaling displayed significant alterations in response to 1-MCP and O3. Analysis of regulatory module networks identified putative transcription factors (TFs) that could be involved in scald. Subsequently, a transcriptional network of the genes-proteins-metabolites and the connected TFs was constructed. This approach enabled identification of several genes co-regulated by TFs, notably encoding glutathione S-transferase (GST) protein(s) with distinct signatures following 1-MCP and O3 treatments. Overall, this study is an important contribution to future functional studies and breeding programs for this fruit, aiding to the development of improved apple cultivars to superficial scald.

Project description:Purpose: The goals of this study was to provide genome-wide data to investigate the molecular mechanism of the interaction between ABA and ethylene during tomato fruit ripening Methods: Regarding the fruits sampled at the 9th day as a well-characterized stage, we used RNA-seq to conducted a comparative analysis of exogenous ABA and NDGA effects on all components involved in biosynthesis and signaling of ethylene and ABA.The identified crucial genes in response to ABA were further performed a ripening time-course analysis by RT-PCR. In addition, we also detected how ethylene affected ABA action at the onset of ripening by treating the fruits with 1-MCP immediately after ABA application. Results: Our study not only illustrated how ABA regulated itself at the transcription level, but also elucidated that ABA can facilitate ethylene production and response by regulating some crucial genes such as LeACS4, LeACO1 and LeETR6 etc. In addition, investigation on the fruits treated with 1-MCP immediately after ABA exposure revealed that ethylene might be essential for the induction of ABA biosynthesis and signaling at the onset of fruit ripening. Furthermore, some specific transcription factors (TFs) known as regulators of ethylene synthesis and sensibility (e.g. MADS-RIN, TAGL1, CNR and NOR etc.) were also observed to be ABA responsive, which implied that ABA influenced ethylene action possibly through the regulation of these TFs expression. Conclusions: Our data suggested that ABA may act as an upstream regulator to modulate ethylene synthesis and signal transduction, which consequently influenced the ripening process. This comprehensive survey not only demonstrated how ABA regulated itself at the molecular level, but also indicated that ABA had a positive impact on ethylene production and action by regulating key genes such as LeACS2, LeACS4, LeACO1 and LeETR6. Besides, our results also revealed that ethylene might be of great importance to induce ABA accumulation and response at the onset of ripening. Moreover, many ripening related TFs, such as MADS-RIN, TAGL1, CNR and NOR, were observed to be affected by ABA, implying that a TF-mediated manner may be involved in the interaction between ABA and ethylene. This study extends our understanding of the mechanism that how ABA-triggered tomato fruit ripening, and illustrates the complex mechanism of reciprocity between ABA and ethylene at the transcription level.
