[PMID: 38099978 PMCID: PMC10920484 DOI: 10.1007/s42770-023-01212-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 12/03/2023] [Indexed: 03/09/2024] Open
Abstract
Sanghuangporus sanghuang is a medicinal macrofungus with antioxidant and antitumor activities, and it is enriched with secondary metabolites such as polysaccharides, terpenes, polyphenols, and styrylpyrone compounds. To explore the putative core genes and gene clusters involved in sanghuang biosynthesis, we sequenced and assembled a 40.5-Mb genome of S. sanghuang (SH1 strain). Using antiSMASH, local BLAST, and NCBI comparison, 12 terpene synthases (TPSs), 1 non-ribosomal peptide synthase, and five polyketide synthases (PKSs) were identified in SH1. Combining the transcriptome analysis with liquid chromatography mass spectrometry-ion trap-time of flight analysis, we determined that ShPKS1, one phenylalanine aminolyase (ShPAL), and one P450 monooxygenase (ShC4H1) were associated with hispidin biosynthesis. Structural domain comparison indicated that ShPKS2 and ShPKS3 are involved in the biosynthesis of orsellinic acid and 2-hydroxy-6-methylbenzoic acid, respectively. Furthermore, comparative genomic analysis of SH1 with 14 other fungi from the Hymenochaetaceae family showed variation in the number of TPSs among different genomes, with Coniferiporia weirii exhibiting only 9 TPSs and Inonotus obliquus having 20. The number of TPSs also differed among the genomes of three strains of S. sanghuang, namely Kangneng (16), MS2 (9), and SH1 (12). The type and number of PKSs also varied among species and even strains, ranging from two PKSs in Pyrrhoderma noxium to five PKSs in S. sanghuang SH1. Among the three strains of S. sanghuang, both the structural domains and the number of PKSs in strains MS2 and SH1 were consistent, whereas strain Kangneng exhibited only four PKSs and lacked the PKS with the structural domain KS-AT-DH-KR-ACP. Additionally, Sanghuangporus species exhibited more similar PKSs to Inonotus, with higher gene similarity around five PKSs, while showing differences from those of other fungi in the same family, including Phellinus lamaoensis. This result supports the independent taxonomic significance of the genus Sanghuangporus to some extent.

Abstract
Two new dipyrroloquinones, namely talaroterreusinones A (1) and B (2), together with four known secondary metabolites, terreusinone A (3), penicillixanthone A (4), isorhodoptilometrin (5), and chrysomutanin (6), were isolated from the solid culture of the endophytic fungus Talaromyces sp. by integrating mass spectrometry-based metabolic profiling and a bioassay-guided method. Their planar structures and stereochemistry were elucidated by comprehensive spectroscopic analysis including NMR and MS. The absolute configuration at C-1″ of terreusinone A (1) was established by applying the modified Mosher's method. Compounds 1-6 were evaluated for anti-inflammatory activity and cytotoxicity. As a result, 1-3 inhibited the LPS-stimulated NO production in macrophage RAW264.7 cells, with IC50 values of 20.3, 30.7, and 20.6 µM, respectively. Penicillixanthone A (4) exhibited potent cytotoxic activity against Hep G2 and A549 cell lines, with IC50 values of 117 nM and 212 nM, respectively, and displayed significant antitumour effects in A549 cells by inhibiting the PI3K-Akt-mTOR signalling pathway.

[PMID: 36144248 PMCID: PMC9505148 DOI: 10.3390/metabo12090844] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 09/06/2022] [Accepted: 09/07/2022] [Indexed: 11/16/2022] Open
Abstract
The whole genome of Cordyceps pseudotenuipes was sequenced, annotated, and compared with three related species to characterize the genome. The antibiotics and Secondary Metabolites Analysis Shell (antiSMASH) and local BLAST analysis were used to explore the secondary metabolites (SMs) and biosynthesis gene clusters (BGCs) of the genus Cordyceps. The genome-wide basic characteristics of C. pseudotenuipes, C. tenuipes, C. cicadae, and C. militaris revealed unequal genome size, with C. cicadae as the largest (34.11 Mb), followed by C. militaris (32.27 Mb). However, the total gene lengths of C. pseudotenuipes and C. tenuipes were similar (30.1 Mb and 30.06 Mb). The GC contents of C. pseudotenuipes, C. tenuipes, C. cicadae, and C. militaris genomes differed slightly (51.40% to 54.11%). AntiSMASH and local BLAST analysis showed that C. pseudotenuipes, C. tenuipes, C. cicadae, and C. militaris had 31, 28, 31, and 29 putative SM BGCs, respectively. The SM BGCs contained different quantities of polyketide synthetase (PKS), nonribosomal peptide synthetase (NRPS), terpene, hybrid PKS + NRPS, and hybrid NRPS + Other. Moreover, C. pseudotenuipes, C. tenuipes, C. cicadae, and C. militaris had BGCs for the synthesis of dimethylcoprogen. C. pseudotenuipes, C. tenuipes, and C. cicadae had BGCs for the synthesis of leucinostatin A/B, neosartorin, dimethylcoprogen, wortmanamide A/B, and beauvericin. In addition, the SM BGCs unique to C. pseudotenuipes were clavaric acid, communesin, and deoxynivalenol. Synteny analysis indicated that the scaffolds where the SM BGC was located were divided into more than 70 collinear blocks, and there might be rearrangements. Altogether, these findings improved our understanding of the molecular biology of the genus Cordyceps and will facilitate the discovery of new biologically active SMs from the genus Cordyceps using heterologous expression and gene knockdown methods.
