Tuberaceae is one of the most diverse lineages symbiotic truffle-forming fungi. To understand molecular underpinning ectomycorrhizal truffle lifestyle, we compared genomes Piedmont white (Tuber magnatum), Périgord black melanosporum), Burgundy aestivum), pig (Choiromyces venosus) and desert (Terfezia boudieri) to saprotrophic Pezizomycetes. Reconstructed gene duplication/loss histories along a time-calibrated phylogeny Ascomycetes revealed that Tuberaceae-specific traits may be related...

Dendrobium spp. are traditional Chinese medicinal plants, and the main effective ingredients (polysaccharides alkaloids) have pharmacologic effects on gastritis infection, cancer, anti-aging. Previously, we confirmed endophytic xylariaceous fungi as dominant in several species of tropical regions from China. In present study, diversity, taxonomy, distribution culturable associated with seven (Orchidaceae) were investigated. Among 961 endophytes newly isolated, 217 (morphotaxa) identified...

Jasmonates (JAs) regulate a wide range of plant defense and development processes. The bioactive JA is perceived by its receptor COI1 to trigger the degradation JASMONATE ZIM-DOMAIN (JAZ) proteins subsequently derepress JAZ-repressed transcription factors for activation expression JA-responsive genes. So far, (+)-7-iso-JA-l-Ile has been only identified endogenous molecule. Here, we designed coronafacic acid (CFA) conjugates with all amino acids (CFA-AA) mimic conjugates, revealed that...

Abstract Diterpene cyclases from bacteria and basidiomycete fungi are seldom studied. Here, we presented the identification verification of EriG, a member UbiA superfamily, as enzyme responsible for cyclization cyathane skeleton in mushroom Hericium erinaceum . Genome mining using EriG protein sequence probe led to discovery new family ubiquitous UbiA‐related diterpene fungi. We successfully characterized seven or with help an engineered Escherichia coli strain determined structures their...

Axonopathy is closely linked to the development of diabetic encephalopathy induced by type II diabetes (T2D). Berberine has been shown cross blood-brain barrier and holds promising effect for neuronal damage in diabetes. The present study investigated protective underlying mechanism berberine on axonopathy both vitro vivo models. High glucose/high fat diet streptozotocin injection-induced T2D rat model was used. administered p.o. 10 weeks. Morris water maze test, tracing,...

Mycorrhizal fungi colonize orchid seeds and induce germination. This so-called symbiotic germination is a critical developmental process in the lifecycle of all species. However, molecular changes that occur during seed remain largely unknown. To better understand mechanism germination, we performed comparative transcriptomic proteomic analysis Chinese traditional medicinal Dendrobium officinale to explore change protein expression at different stages asymbiotic identify key proteins...

Probiotics have garnered increasing attention as a potential therapeutic approach for type 2 diabetes mellitus (T2DM). Previous studies confirmed that Bifidobacterium animalis subsp. lactis MN-Gup (MN-Gup) could stimulate the secretion of glucagon-like peptide-1 (GLP-1) in NCI-H716 cells, but whether has hypoglycemic effect on T2DM vivo remains unclear. In this study, mouse model was constructed, with high-fat diet and streptozotocin mice, to investigate diabetes. Then, different doses (2 ×...

The lion's mane mushroom Hericium erinaceus is a famous traditional medicinal fungus credited with anti-dementia activity and producer of cyathane diterpenoid natural products (erinacines) useful against nervous system diseases. To date, few studies have explored the biosynthesis these compounds, although their chemical synthesis known. Here, we report first genome tanscriptome sequence H. erinaceus. size 39.35 Mb, containing 9895 gene models. reveals diverse enzymes large family cytochrome...

Anoectochilus roxburghii (Wall.) Lindl. (Orchidaceae) is an endangered medicinal plant in China, also called “King Medicine”. Due to lacking of sufficient nutrients dust-like seeds, orchid species depend on mycorrhizal fungi for seed germination the wild. As part a conservation plan species, research necessary. However, molecular mechanism and underlying orchid-fungus interactions during symbiotic are poorly understood. In this study, Illumina HiSeq 4000 transcriptome sequencing was...
