Multi-Omics Insights into Postharvest Deterioration in Artichoke for Enhanced Shelf Life and Health Benefits

ABSTRACT: Artichokes provide a wide range of health-promoting nutrients and produce ornamental flowers with pleasant sensory appeal. However, their high photosynthetic activity, respiration rate, and sensitivity to mechanical injuries makes them highly perishable. Using the high-throughput RNA-seq and metabolomics analysis, we identified significant variations in the expression levels of differentially expressed genes (DEGs) and metabolites between ‘Green Queen’ (GQ) and ‘Imperial Star’ (IS) cultivars, relating to their shelf-life. The DEGs were categorized into pathways involved in hormone signaling, cell wall metabolism, stress response, organ development, and health beneficial compounds with expression varying across storage intervals. Notably, genes and transcription factors (TFs) involved in plant hormone signaling pathways and senescence were primarily upregulated in IS, explicating its shorter shelf life. Genes such as b -carotene 3-hydroxylase (BHY) and 11-beta-hydroxysteroid dehydrogenase-like 4A (HSD4), upregulated in both cultivars during storage, facilitate the production of metabolites with reported anti-aging, anti-inflammatory, diabetic resistance, and cardiovascular benefits. Metabolomics analysis unveils an accumulation of phenols, flavonoids, vitamins and breakdown of inulin, which remain stable in GQ and occur in a time-dependent manner in IS during storage. These findings elucidate the genotypic effect on the shelf-life of artichoke stored under same conditions and provide valuable insights for improving postharvest shelf life and nutritional quality through gene editing techniques.

Project description:Lettuce (Lactuca sativa L.) is a highly perishable horticultural crop with a relatively short shelf life due to leaf senescence that limits its commercial value and contributes to food waste. Postharvest senescence varies with influences of both environmental and genetic factors. Preharvest genetic factors can be indicative of postharvest quality. Discovery of additional preharvest markers to assess lettuce shelf life is an important step towards increasing the efficiency of lettuce breeding efforts for improved shelf life. We selected and evaluated three romaine lettuces with variable shelf lives with the aim of identifying preharvest markers of lettuce postharvest shelf life. We evaluated leaf morphological characteristics for each of the three cultivars. To assess molecular indicators of shelf life, we used an RNA sequencing approach to construct transcriptomic profiles of two of the cultivars, a short shelf life (SSL) breeding line 60184 and a long shelf life (LSL) cultivar ‘Okeechobee’ at maturity. We identified 552 upregulated and 315 downregulated differentially expressed (DE) genes between the genotypes. We found that 27 % of the DE lettuce genes had an Arabidopsis thaliana ortholog characterized as senescence-associated, indicating that variable expression of senescence-associated genes (SAGs) could serve as a tool for preharvest markers of postharvest shelf life. Notably, we identified several SAGs and functional groupings with highly differential expression between the cultivars. This includes several jasmonate ZIM-domain (JAZ), jasmonic acid (JA) signaling genes, chlorophyll a-b binding (CAB) chloroplast-associated genes, and cell wall modification genes including pectate lyases (PL) and expansins (EXP). This study presented an innovative approach for identifying molecular markers for preharvest factors linked to postharvest traits for prolonged shelf. These genes could potentially be developed further as preharvest predictors of shelf life for lettuce breeding

Project description:Fresh fish are highly perishable food products and their short shelf-life limits their commercial exploitation, leads to waste and has a negative impact on aquaculture sustainability. New non-thermal food processing methods, such as High pressure (HP), are being investigated to prolong shelf-life while assuring high food quality. We applied several tools to evaluate the impacts of HP processing on European sea bass (Dicentrarchus labrax) fillets quality and shelf life. The data here presented includes visual and physical measurements of flesh quality and the microbiome and proteome profiles of control and HP-processed sea bass fillets (600MPa, 25ºC, 5min), after isothermal storage (2°C) for different periods ranging from 1 to 67 days. Color (L-, a- and b- values) change and texture (hardness, cohesiveness and adhesiveness) parameters were obtained by using appropriate colorimeter and texture analyser, respectively, during refrigerated storage. Bacterial diversity was analysed by Illumina high-throughput sequencing of the 16S rRNA gene in five pooled DNAs from control or HP-processed fillets after 1, 11 or 67 days and the raw reads were deposited in the NCBI-SRA database with accession number PRJNA517618. In addition, high-throughput sequencing of the internal transcribed spacer (ITS) region targeting yeast and moulds was run for control or HP-processed fillets at the end of storage (11 or 67 days, respectively), being deposited under SRA accession PRJNA517779. Quantitative label-free proteomics profiles were analysed by SWATH-MS (Sequential Windowed data independent Acquisition of the Total High-resolution-Mass Spectra) in myofibrillar or sarcoplasmic enriched protein extracts pooled for control or HP-processed filets after short (1d) or long-term (11-67 days) storage. These data support the findings reported in “High pressure processing of European sea bass (Dicentrarchus labrax) fillets and tools for flesh quality and shelf life monitoring” (Tsironi et al. 2019).
