| Abstract: | "Rhodosporidiobolus odoratus, one of the oleaginous red yeasts, is gaining biotechnological importance for their ability to produce microbial lipids and carotenoids. However, to date, the genomic resource underling lipid and carotenoid biosynthesis in R. odoratus has not been reported. Here, we reported the first genome assembly of R. odoratus using a combination of PacBio and Illumina techniques. The final genome assembly is 23.74 Mb in size, containing 52 scaffolds with a N50 length of 1200,460 bp and a GC content of 56.90%. Benchmarking Universal Single-Copy Orthologs (BUSCO) assessment showed that our assembly contains 94.23% of Basidiomycota universal single-copy orthologs. The genome was predicted to contain 4986 protein-coding genes, 4967 of which were functionally annotated. Metabolomic profiling identified 574 lipids, 3 carotenoids, and 208 volatile organic compounds synthesized by R. odoratus. Integrative analysis of genomics and metabolomics provides insights into the biosynthesis of lipid, carotenoid, and other bioactive compounds in R. odoratus. Collectively, the results presented herein greatly enhance our understanding of R. odoratus in lipids and carotenoids biosynthesis, and thus further accelerate its fundamental molecular investigations and biotechnological applications" |
