Project description:Plant-derived nanovesicles (PDNVs) were isolated from Ginkgo biloba seed homogenate using differential ultracentrifugation (DUC) followed by density gradient ultracentrifugation (DGUC) with linear and non-linear iodixanol gradients. Nanoparticle tracking analysis (NTA) and cryo-transmission electron microscopy (cryo-TEM) characterized vesicle size, concentration, and morphology. Untargeted mass spectrometry profiled the protein content of distinct PDNV fractions. Ginkgo PDNVs formed a heterogeneous population, including single- and double-bilayer vesicles >50 nm. Proteomics revealed seed storage proteins (legumin, ginnacin) and membrane-associated ATPases, HSP90, catalase, PEPC, and eEF1A. Ginkgo seed-derived PDNVs exhibit promising vascular protective and anti-inflammatory properties, supporting their potential as safe, multifunctional agents for endothelial modulation.
Project description:We conducted RNA-seq from the Ginkgo leaves after UV-B treatment,and constructed the molecular regulatory network of flavonoids synthesis under UV-B radiation in G. biloba.
Project description:To explore the overall long noncoding RNA (lncRNA) involved in major developmental stages of Ginkgo biloba leaves , we deeply sequenced samples of leaves from different developmental stages (from April to October) using strand-specific RNA sequencing (ssRNA-seq) menthod. We obtained 27.44 Gb raw data and identified 1323 novel lncRNAs. We also categorized the novel lncRNAs as intergenic, intronic, antisense and sense based on their location on theGinkgo biloba genome. Furthermore, lncRNAs targeted protein-coding genes were predicted and functional annotated. In addition, we constructed a network of interactions between ncRNAs (miRNAs, lncRNA) and mRNAs. Our results suggest that the identified novel lncRNAs are important in modulating development process of Ginkgo biloba, and provide a rich resource for further research on the function of these novel lncRNAs.
