A cold storage system is useful for maintaining the quality of hardy kiwifruit. However, extended periods inevitably result in stress, leading to lower fruit marketability; severity chilling injury depends on types and cultivars. In this study, impact conditions physicochemical properties antioxidant capacity two phenotypically different kiwifruit cultivars-'Cheongsan' (large type) 'Daebo' (small type)-stored at low (L; 3 °C, relative humidity [RH]; 85-90%) moderate-low (ML; 5 RH; temperatures was determined. Significant differences firmness titratable acidity between treatments L ML were observed both cultivars during experimental period. Meanwhile, browning pitting rates 'Cheongsan' fruits treatment increased 8 weeks compared with those ML; nonetheless, decay after 6 weeks. The total chlorophyll, carotenoid, flavonoid, ascorbic acid concentrations as well activities significantly differed ML. After 2 storage, had content than These results demonstrate that attributes activity are influenced by low-temperature specific Our findings suggest optimal conditions, each cultivar, promise maintain quality, including their health-promoting compounds, long-term storage.

Kiwifruit spatiotemporal multiomics networks uncover key tissue-specific regulatory processes throughout the life cycle

PLANT PHYSIOLOGY, Год журнала: 2024, Номер unknown

Kiwifruit (Actinidia chinensis), a recently commercialized horticultural crop, is rich in various nutrient compounds. However, the regulatory networks controlling dynamic changes key metabolites among different tissues remain largely unknown. Here, high-resolution spatiotemporal datasets obtained by ultraperformance liquid chromatography-tandem mass spectrometry methodology and RNA-seq were employed to investigate metabolic transcriptional landscape of major kiwifruit across developmental stages, including from fruit skin, outer pericarp, inner core. (KSRN) constructed integrating 1,243 identified co-expressed genes into 10 clusters 11 modules based on their biological functions. These allowed generation global map for occurring throughout life cycle discovery underlying networks. KSRN predictions confirmed previously established networks, accumulation anthocyanin ascorbic acid (AsA). More importantly, led functional characterization three transcription factors: an A. chinensis ethylene response factor 1, which negatively controls sugar production perceiving ripening signal, basic-leucine zipper 60 (AcbZIP60) factor, involved biosynthesis AsA as part L-galactose pathway, related apetala 2.4 (RAP2.4), directly activates expression kiwi aroma terpene synthase gene AcTPS1b. Our findings provide insights metabolism generate valuable resource study processes well other fruits.

Metabolic profiling and gene expression analyses provide insights into cold adaptation of an Antarctic moss Pohlia nutans

Frontiers in Plant Science, Год журнала: 2022, Номер 13

Antarctica is the coldest, driest, and most windy continent on earth. The major terrestrial vegetation consists of cryptogams (mosses lichens) two vascular plant species. However, molecular mechanism cold tolerance relevant regulatory networks were largely unknown in these Antarctic plants. Here, we investigated global alterations metabolites pathways an moss (Pohlia nutans) under stress using integrated multi-omics approach. We found that proline content several antioxidant enzyme activities significantly increased P. nutans stress, but contents chlorophyll total flavonoids markedly decreased. A 559 detected ultra high-performance liquid chromatography/electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). observed 39 71 differentially changed (DCMs) after 24 h 60 indicating activated for producing fatty acids, alkaloids, flavonoids, terpenoids, phenolic acids. In addition, quantitative transcriptome sequencing was conducted to uncover transcriptional profiles stress. representative expressed genes (DEGs) identified summarized function including Ca2+ signaling, ABA jasmonate acids biosynthesis, flavonoid other biological processes. dataset analyses metabolome revealed auxin very-long-chain biosynthesis might contribute acclimating Overall, observations provide insight into adaptations polar habitats impact climate change

Integrative physiological, transcriptome, and metabolome analyses reveal the associated genes and metabolites involved in cold stress response in common vetch (Vicia sativa L.)

Abstract As an economically important legume, Vicia sativa is commonly used as fodder for livestock and in health‐promoting foods human consumption; however, cold stress one of the most limitations to its utilization at high altitudes. The shoot tissues three cold‐resistant (Lan1, Lan2, Lan3) cold‐sensitive (368, 521, 538) accessions were collected after (4°C) treatment 0, 6, 48 h assess their molecular regulatory mechanisms during via integrative analyses transcriptomes metabolomes. Our Kyoto Encyclopedia Genes Genomes enrichment analysis showed that biosynthesis phenylpropanoids was enriched pathway response V. sativa. A total 18 differential metabolites obtained phenylpropanoid pathway, 722 differentially expressed genes (DEGs) a significant positive correlation with naringenin p‐coumaric acid following weighted gene co‐expression network analysis, while 84 DEGs negative associations. Moreover, four overexpressed yeast, it indicated biological function confer tolerance. These results provide valuable resource understanding underlying mechanism 's furthering development breeding research.
