SMRT-based mitochondrial genome of the edible mushroom Morchella conica.

ABSTRACT: Morchella conica Pers. is a highly-prized mushroom for its edible and medical values. In this study, we determined the complete mitochondrial genome of M. conica combining both PacBio and Illumina sequencing technologies. The complete mitochondrial genome is 280,763 bp in length with a GC content of 39.88%. We identified a total of 14 core conserved protein-coding genes, 127 non-conserved open reading frames (ncORFs) and 30 tRNA genes in the M. conica mitogenome. However, no large or small rRNA subunits (rnl or rns) were identified in this mitogenome. In addition, we detected two mitochondrial RNase P (rnpB) genes and one ribosomal protein genes (rps3). Phylogenetic analysis was performed among M. conica and 18 other representative fungi from Ascomycota, Basidiomycota and Mucoromycota. Our results showed that M. conica was most closely related to M. importuna. The availability of the M. conica mitochondrial genome will form the basis of genetic breeding program and enhance our understanding of the evolution of this species.

Whole-genome sequencing and evolutionary analysis of the wild edible mushroom, Morchella eohespera.

Project description:Morels (Morchella, Ascomycota) are an extremely desired group of edible mushrooms with worldwide distribution. Morchella eohespera is a typical black morel species, belonging to the Elata clade of Morchella species. The biological and genetic studies of this mushroom are rare, largely hindering the studies of molecular breeding and evolutionary aspects. In this study, we performed de novo sequencing and assembly of the M. eohespera strain m200 genome using the third-generation nanopore sequencing platform. The whole-genome size of M. eohespera was 53.81 Mb with a contig N50 of 1.93 Mb, and the GC content was 47.70%. A total of 9,189 protein-coding genes were annotated. Molecular dating showed that M. eohespera differentiated from its relative M. conica at ~19.03 Mya (million years ago) in Burdigalian. Evolutionary analysis showed that 657 gene families were contracted and 244 gene families expanded in M. eohespera versus the related morel species. The non-coding RNA prediction results showed that there were 336 tRNAs, 76 rRNAs, and 45 snRNAs in the M. eohespera genome. Interestingly, there was a high degree of repetition (20.93%) in the M. eohespera genome, and the sizes of long interspersed nuclear elements, short interspersed nuclear elements, and long terminal repeats were 0.83 Mb, 0.009 Mb, and 4.56 Mb, respectively. Additionally, selection pressure analysis identified that a total of 492 genes in the M. eohespera genome have undergone signatures of positive selection. The results of this study provide new insights into the genome evolution of M. eohespera and lay the foundation for in-depth research into the molecular biology of the genus Morchella in the future.

Gene Expressing Difference in Sclerotial Formation of Morchella conica.

Project description:The difference of gene expression between sclerotia-producing and non-sclerotia-producing single spore isolates from Morchella conica were preliminary analyzed by mRNA differential display reverse transcription-polymerase chain reaction (RT-PCR) technique and 67 differential gene fragments were obtained. Fifty-eight of their second PCR products were cloned and sequenced. Thirteen special differential gene fragments related to sclerotial formation were validated by semi-quantitative RT-PCR. Some gene fragments had certain homologies with lipoprotein, cyclin-dependent kinase C-3, glycerophosphoryl diester phosphodiesterase, Rho GDP-dissociation inhibitor, gamma-aminobutyrate permease, OmpA family protein, Transcript antisense to ribosomal RNA protein, sodium-calcium exchange protein and keratin-associated proteins 5, 6. In addition, the putative protein of some DNA fragments had higher similarity with hypothetical protein-coding gene in NCBI database, as well as some were only putative gene fragments. All these fragments were speculated to be the functional gene associated with sclerotial formation in morel.

Complete mitochondrial genome of the edible mushroom Singerocybe alboinfundibuliformis (Clitocybaceae, Agaricales).

Project description:Singerocybe alboinfundibuliformis (Seok et al.) Yang, Qin & Takah 2014 is an edible mushroom distributed in several East or Southeast Asian countries. Herein, we report the mitochondrial genome of S. alboinfundibuliformis based on Illumina sequencing data. The overall length of the mitochondrial genome is 64,279 bp, with a GC content of 29.0%. It contains 14 typical protein-coding genes, 27 tRNA genes, two rRNA genes, and 13 intergenic ORFs. Most of these genes (39 out of 56) are transcribed at the forward strand, and few (17 out of 56) are transcribed at the reverse strand. Among these genes, only the rnl gene is invaded by an intron, and all other genes are intron-free. Phylogenetic analysis based on mitochondrial amino acid sequences supports the phylogenetic position of S. alboinfundibuliformis in Clitocybaceae, being close to Lepista sordida (Schumach.) Singer 1951. This study serves as a springboard for future investigation on fungal evolution in Clitocybaceae.

The mitochondrial genome of a wild edible mushroom, Russula rosea.

Project description:Russula rosea is a common wild edible ectomycorrhizal fungus, which is widely distributed all over the world. We assembled the complete mitochondrial genome of R. rosea with the total length was 54177 bp and the GC content of 22.34%. It contains a total of 57 genes, including 14 standard protein-coding genes, one conserved ribosomal protein S3 gene (rps3), two rRNA genes, 24 tRNA genes, 15 free-standing open reading frames (ORFs) and one DNA polymerase gene (dpo). Mitochondrial genome found a close evolutionary relationship between Russula rosea and Russula lepida, which was helpful to study the genetic evolutionary relationship of edible fungi.

The complete mitochondrial genome of the edible mushroom Grifola frondosa.

Project description:The culinary-medicinal mushroom Grifola frondosa is widely cultivated in East Asia. In this study, the complete mitochondrial genome of G. frondosa was determined using Illumina sequencing. The circular molecule was 197,486 bp in length with a content of 25.01% GC, which was one of the largest mitochondrial genomes in the order Polyporales. A total of 39 known genes encoding 13 common mitochondrial genes, 24 tRNA genes, 1 ribosomal protein s3 gene (rps3), and 1 DNA polymerase gene (dpo) were predicted in this genome. The phylogenetic analysis showed that G. frondosa clustered together with Sparassis crispa, Laetiporus sulphureus, Wolfiporia cocos, and Taiwanofungus camphoratus. The complete mitochondrial genome reported here may provide new insight into genetic information and evolution for further studies.

The complete mitochondrial genome of the edible Basidiomycete mushroom Thelephora ganbajun.

Project description:The complete mitochondrial genome of the edible fungus Thelephora ganbajun was determined using Illumina sequencing. This mitogenome is a circular molecule of 52,857 bp in length with a GC content of 25.73%.

The evolutionary relationships between Th. ganbajun and other representative species based on the mitogenome are consistent with those based on nuclear genes. The mitogenome information of Th. ganbajun should contribute to our understanding of the diversity and evolution of Thelephorales.
