Symptoms initially appeared as small, irregular spots on the infected . The authors are grateful to Prof. Francis Martin for critical discussion and suggestion and to Dr. Lin-Chun Shi and Dr. Li-Si Zhou for helpful support during the data submission to Genbank database. These genes are likely responsible for the 1,6- or 1,7-cyclization of 3R-nerolidyl diphosphate (NPP) (Cop6) or involved in the biosynthesis of - and -barbatene (Omp9), compounds known to be produced by fungi and plants and carotane sesquiterpenes (Omp10). Cultivated enokitake are not exposed to light, resulting in white or pallid fruitbodies with long stipes and small caps. Liu XB, Feng B, Li J, Yan C, Yang ZL. Received 2020 Feb 14; Accepted 2020 Sep 28. This study investigated fruiting body development in F. filiformis by comparing transcriptomes of 4 developmental stages, and compared the developmental genes to a 200-genome dataset to . The wild strain Liu355 used for genomic sequencing was kindly provided by Prof. H. W. Liu (State Key Laboratory of Mycology, Institute of Microbiology, Chinese Academy of Sciences) and was first isolated from the fruiting body of F. filiformis collected from Longling, Yunnan Province, southwestern China. In addition, as a typical white-rot fungus, F. filiformis can effectively degrade lignin and produce alcohol dehydrogenase, and thus exhibiting potential for application in bioethanol production [13]. This study obtained complete mitogenomes of 44 wild isolates collected from nine provinces and two artificially bred cultivars of F. filiformis, together with three Flammulina rossica isolates and one Flammulina fennae isolate for comparison.

Differential expression of RNA-Seq data at the gene level-the DESeq package. relevant scientific literature for the most reliable information. Based on a genome-wide search, four genes encoding heterotrimeric G protein subunits were identified in F. filiformis. Length polymorphism was widely observed in intergenic regions. 1. 2015;132635. Reference: How to cite this resource - Schoch CL, et al. Symptoms initially appeared as small, irregular spots on the infected pileus, with color ranging from pale yellow to light brown. The golden-needle mushroom Flammulina filiformis is one of the bulk mushroom products in the world. The mitogenome of F. filiformis ranged from 83,540 bp to 90,938 bp, consisting of 14 conserved protein-coding genes (PCGs), two rRNA genes, and 25 tRNA genes. Here, we used the model basidiomycete mushroom Flammulina filiformis to investigate the mechanism of mushroom stipe elongation and the role of reactive oxygen species (ROS) signaling in this process. Genes with an adjusted P-value <0.05 were considered differentially expressed. Unlike popular Asian mushrooms like shiitake or king oyster, enoki mushroom has a rather mild, slightly fruity taste. F. filiformis is enriched in a number of gene clusters involved in the biosynthesis of polysaccharides and terpenoid bioactive compounds and these genes usually display differential expression between wild and cultivar strains, even in different developmental stages. All authors read and approved the final manuscript. Blin K, Kim HU, Medema MH, Webe T. Recent development of antiSMASH and other computational approaches to mine secondary metabolite biosynthetic gene clusters. Individual fruitbodies are up to 50mm (2in) tall, the cap convex at first, becoming flat when expanded, up to 45mm (1.75in) across. Functional annotation of the predicted genes showed that more than half the predicted genes were annotated in the NCBI Non-Redundant Protein Sequence Database (NR) (6383 genes) and 5794, 2582, 1972 and 837 genes were annotated in the databases Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), Clusters of Orthologous Groups (COG) and SwissProt, respectively. Transcriptomic and proteomic analyses of F. filiformis revealed key genes associated with cold- and light-stress fruiting body morphogenesis [34]. The formula is below: N represented the all gene number with pathway annotation, n is the DEGs number of N, M refers the all gene number annotated in a specific pathway and m is the DEGs number annotated in a specific pathway. It is well known for its role in Japanese cuisine, where it is called enokitake and is widely cultivated in east Asia.

Sturn A, Quackenbush J, Trajanoski Z. Genesis: cluster analysis of microarray data. To date, the genomes of three cultivars of F. filiformis from Japan, Korea and China were sequenced respectively. Comparative studies of filamentous fungal species have shown that secondary metabolism gene clusters are often either highly divergent or uniquely present in one or a handful of species [38]. DNA sequencing of the internal transcribed spacer (ITS) region of F. filiformis (HKAS85819) was listed under GenBank accession number {"type":"entrez-nucleotide","attrs":{"text":"KP867925","term_id":"849083805","term_text":"KP867925"}}KP867925 [9]. We performed DIAMOND search against the CAZy pre-annotated CAZyme sequence database and combined with corresponding gene functional annotation to get the annotation result. Flammulina filiformis ( Dai and Yang, 2018 ), known as winter mushroom or enokitake, belongs to the family Physalacriaceae, Agaricales ( Ge et al., 2015 ). All the downstream analyses were based on the clean data with high quality. Hierarchical clustering of gene expression was conducted using Genesis 1.7.7 [64]. In our study, genome and transcriptome sequencing and the assembly and annotation of the high-temperature-tolerant wild F. filiformis strain were carried out, and the gene clusters associated with polysaccharides, terpenoid and polyketide biosynthesis were predicted. The two gene clusters both included core genes encoding polyketide synthases (gene8217 and gene1373). A temperature downshift (cold stimulation) is considered to be one of the most important and essential environmental factors for the fruiting initiation and fruiting body formation of F. filiformis [34]. Flammulina filiformis is a species of agaric (gilled mushroom) in the family Physalacriaceae. In addition, GO term enrichment of differentially expressed genes (DEGs) between the wild strain Liu355 and cultivar strain CGMCC 5.642 showed that most genes displayed a similar expression profile, but peptide biosynthetic and metabolic process (GO:0006518; GO:0043043), amide biosynthetic process (GO: 0043604) and ribonucleoprotein complex (GO: 1901566) were upregulated in the cultivar strain of CGMCC 5.642. The numbers of gene clusters involved in terpene, PKS and NRPS biosynthesis were different in the wild strain Liu355 compared with the other three cultivar strains (KACC42780, TR19 and L11 with genome sequencing) and the gene number related to terpene synthesis was higher in the wild strain Liu355 (119 genes) than in the cultivar strain L11 (81 genes) (Table3). Wishlist. Golden needle mushroom: a culinary medicine with evidenced-based biological activities and health promoting properties. It has been reported that China is currently the largest producer of F. filiformis, with an annual production of 2.4 million tons [3]. The lysine content in F.filiformis showed the same trend as increased at low concentration of -ketoglutaric acid and reduced at high concentration.2.5 mmol/L was the best concentration to induce lysine synthesis. Epub 2020 Jul 27. Kanehisa M, Tanabe M, Sato Y, Morishima K. KEGG: new perspectives on genomes, pathways, diseases and drugs. After that, the high-quality reads were mapped to the reference genome sequence of F. filiformis L11 (Bioproject PRJNA191865) using BWA v0.5.9-r16 software. [6] Enokitake are typically grown in the dark, producing pallid fruitbodies having long and narrow stipes with undeveloped caps.

Biodegradation of ramie stalk by. 3 and Additionalfile6: Table S3). Agroclavine dehydrogenase is involved in the biosynthesis of the fungal ergot alkaloid ergovaline [45] and--glucan synthesis-associated protein is likely linked to the biosynthesis of fungal cell wall polysaccharides. filiformis Z.W. Epub 2019 May 14. This mushroom has a tetrapolar mating system that consists of homeodomain . MeSH Among them, the gene expression levels of the three MYB TFs in the mycelium stage were higher than that in other growth and development stages [ 35 ]. The purpose of a mushroom is to release spores into the air, but a mushroom trapped underneath bark cannot accomplish this task because it has no access to the air currents. A total of 6577 genes were commonly expressed in all tissues. In addition, Sequence homology searches method (BlastP) was also used to identify genes related to terpenoid biosynthesis. official website and that any information you provide is encrypted [3] Further molecular research using a combination of different sequences has shown that F. filiformis and F. velutipes are distinct and should be recognized as separate species.[2].
