“…These two molecules are the starting compounds for the synthesis of all isoprenoids and their condensation forms geranyl diphosphate (GPP), which is the precursor of C 10 monoterpenoids. 41 Instead, two molecules of IPP and one molecule of DMAPP can be combined to produce farnesyl diphosphate (FPP), which is the precursor for C 15 sesquiterpenes. In carambola fruits, both MVA and MEP pathways were upregulated in FT and KT, boosting the concentrations of seven downstream C 10 monoterpenoids (o- Linoleic and Linolenic Acid Pathway.…”

Carambola is a tropical fruit that is highly sought after by consumers due to its unique flavor, star shape, and nutritional value. Enhancing the flavor quality of this fruit can increase the consumer acceptance and market demand. However, flavor is an intrinsic characteristic of fruits. Its decoding requires in-depth knowledge based on recognizing key biological pathways relevant to flavor formation and development. In this study, the volatile and non-volatile metabolites contributing to the flavor variation of five carambola cultivars were investigated by a novel strategy combining GC–MS/O-based volatilomics with LC–MS-based metabolomics. Several significant flavor-related pathways, involving biosynthesis or metabolism of amino acids, terpenoids, fatty acids, sugar and organic acid, and flavonoids were identified based on the enrichment analysis of important volatile and non-volatile metabolites. The results indicated that there were metabolites in the flavor-related pathways being up- or downregulated, leading to the differences in flavor traits of different carambola cultivars. This study could provide a valuable reference for breeders and researchers of interest in the mechanisms underlying the regulation of flavor, which would ultimately lead to the creation of carambola cultivars with more attractive flavor profiles and pleasurable consuming experiences.

“…Transcriptomic studies in mango have revealed valuable information regarding the gene expression patterns associated with aroma biosynthesis pathways in various mango cultivars and stages of development. The differential expression of these genes within different tissues and ripening phases plays a crucial role in shaping the distinct avor characteristics observed in diverse mango varieties (53). Date palm is a plant with a considered to notable withstand high levels of salinity as per transcriptomic analyses where speci c genes implicated in conferring salt tolerance have been recognized, notably including those associated with ion transport proteins as well as auxin-responsive genes (54).…”

Background Fruit crops, including tropical and subtropical fruits like Avocado (Persea americana), Fig (Ficus carica), Date Palm (Phoenix dactylifera), Mango (Mangifera indica), Guava (Psidium guajava), Papaya (Carica papaya), Pineapple (Ananas comosus), and Banana (Musa acuminata) are economically vital, contributing significantly to global agricultural output, as classified by the FAO's World Programme for the Census of Agriculture. Advancements in next-generation sequencing, have transformed fruit crop breeding by providing in-depth genomic and transcriptomic data. RNA sequencing enables high-throughput analysis of gene expression, and functional genomics, crucial for addressing horticultural challenges and enhancing fruit production. The genomic and expression data for key tropical and sub-tropical fruit crops is currently lacking a comprehensive expression atlas, revealing a significant gap in resources for horticulturists who require a unified platform with diverse datasets across various conditions and cultivars. Results The Fruit Expression Atlas (FEAtl), available at http://backlin.cabgrid.res.in/FEAtl/index.php, is a first-ever extensive and unified expression atlas for tropical and subtropical fruit crops developed using 3-tier architecture. The expressivity of coding and non-coding genes, encompassing 2,060 RNA-Seq samples across 91 tissue types and 177 BioProjects, it provides a comprehensive view of gene expression patterns for different tissues under various conditions. FEAtl features multiple tabs that cater to different aspects of the dataset, namely, Home, About, Analyze, Statistics, and Team and contains seven central functional modules: Transcript Information, Sample Information, Expression Profiles in FPKM and TPM, Functional Analysis, Genes Based on Tau Score, and Search for Specific Gene. The expression of a transcript of interest can be easily queried by searching by tissue ID and transcript type. Expression data can be displayed as a heat map, along with functional descriptions as well as Gene Ontology and Kyoto Encyclopedia of Genes and Genomes. Conclusions This atlas represents a groundbreaking compilation of a wide array of information pertaining to eight distinct fruit crops and serves as a fundamental resource for comparative analysis among different fruit species and is a catalyst for functional genomic studies.

“…Terpene compounds, particularly monoterpenes and sesquiterpenes, signi cantly contribute to grape aroma, with monoterpenes being responsible for the strong rose aroma in Shine Muscat grapes [13]. Terpene compounds are synthesized through C5 isoprene structural units, with monoterpene compounds synthesized through the methyl erythritol phosphate (MEP) pathway in plastids, and the biosynthesis of sesquiterpenes primarily carried out through the mevalonate (MVA) pathway in the cytoplasm [14][15]. C6 compounds, including C-aldehydes, alcohols, and ester compounds, produce "green odors" in grapes, classi ed as green leaf volatiles (GLVs).…”

Background: Aroma components play a crucial role in grape quality formation, and diverse cultivation environments significantly impact grape aroma metabolism. This study aims to explore the differences in aroma metabolism in Shine Muscat grapes under summer and winter growth conditions in Guangxi, utilizing HS-SPME-GC-MS for aroma component measurement at different developmental stages. Omics analysis is combined to elucidate the changes in aroma components. Results: In both summer and winter, the predominant free aroma components of grape fruits were aldehydes, terpenes, and alcohols, while bound aroma components were mainly phenols, alcohols, and terpenes. Winter fruits exhibited significantly higher total free aroma content and monomeric compound content compared to summer. Specifically, the concentration of (E)-2-hexenal was higher in winter fruits, whereas (Z)-3-hexen-1-ol showed the opposite trend. Transcriptome and qPCR results indicated that changes in C6 compounds in Shine Muscat grapes were consistent with VvLOXA, VvHPL1, and VvADH1. The differential expression of VvLOXA or VvADH1 in winter fruit may explain the higher concentration of (E)-2-hexenal or lower content of (Z)-3-hexen-1-ol in Shine Muscat grapes during winter. Conclusions: This study reveals significant differences in the aroma metabolism of Shine Muscat grapes between summer and winter seasons, providing a foundation for regulating aroma accumulation through temperature and water control in production.
