Special Issue Information

Dear Colleagues,

The Special Issue, titled "Fungal Growth and Development Based on Functional Genomics and Microbiomics", aims to explore the intricate mechanisms governing fungal growth and development, as well as their interactions with microbial communities, through cutting-edge genomic and microbiomic technologies. This Issue seeks to gather innovative research that elucidates the genetic mechanisms underpinning fungal development, growth patterns, and interactions within diverse microbial communities. By integrating functional genomics and microbiome analyses, we aim to uncover how environmental factors, host interactions, and microbial cohabitation influence fungal behavior and physiology. Contributions may include studies on gene expression profiling, metabolic pathways, symbiotic partnerships, and the role of environmental stresses in shaping fungal communities. The overarching goal is to advance our understanding of fungal biology and its ecological significance, providing insights that could lead to novel applications in agriculture, biotechnology, and medicine. We invite researchers from various disciplines to submit their findings and contribute to this growing field of study.

The growth of Flammulina filiformis is strongly dependent on low-temperature cues for the initiation of primordia formation. To obtain a comprehensive understanding of the molecular mechanisms that govern the mycelial response to cold stress, de novo genome sequencing of the F. filiformis monokaryon and multi-omics data (transcriptome and metabolome) analyses of the mycelia, primordia, and fruiting bodies were conducted in the present study. Genome sequencing based on PacBio HiFi and Hi-C resulted in a 36.3 Mb genome sequence that mapped to 12 chromosomes, comprising 11,886 protein-coding genes. A total of 25 cold-responsive (COR) genes and 520 cold-adapted enzymes were identified in the genome. Multi-omics analyses showed that the pathways related to carbohydrate metabolism in the mycelia under low temperature (10 °C) were significantly enriched. Further examination of the expression profiles of carbohydrate-active enzymes (CAZymes) involved in carbohydrate metabolism revealed that out of 515 CAZyme genes in F. filiformis, 58 were specifically upregulated in mycelia under low-temperature conditions. By contrast, the expression levels of these genes in primordia and fruiting bodies reverted to those prior to low-temperature exposure. These indicate that CAZyme genes are important for the low-temperature adaptation of F. filiformis. This research contributes to the targeted breeding of F. filiformis. Full article

Sclerotinia sclerotiorum, a fungal pathogen that is spread worldwide and causes serious diseases on crops, can be parasitized specifically by the mycoparasite Coniothyrium minitans. SsNEP2, encoding a necrosis-inducing protein in S. sclerotiorum, was previously inferred to play a role in the virulence to host plants. In this study, silencing of SsNEP2 in S. sclerotiorum had no significant (p < 0.01) influence on mycelial morphology, while overexpression led to lower mycelial growth and more branches. When amended with the fermentation broth of the SsNEP2 silencing mutants, conidial germination of C. minitans was promoted, while conidial production decreased. When parasitized by C. minitans, enhanced resistance of the SsNEP2 silencing mutants and weaker resistance of the overexpressed transformants were observed compared to the wild-type S. sclerotiorum strain 1980. In addition, the expression of SsNEP2 in C. minitans enhanced mycelial parasitism on S. sclerotiorum and restored the effect of silencing SsNEP2 in S. sclerotiorum on mycoparasitism. Thus, we highlight the role of SsNEP2 as a PAMP-like protein in the mycoparasitism between C. minitans and its host fungus S. sclerotiorum. SsNEP2 can be used to promote the biological potential of C. minitans.

Helvella bachu, an ectomycorrhizal fungus, forms a symbiotic relationship with Populus euphratica, a rare and endangered species crucial to desert riparian ecosystems. In this study, endofungal bacteria (EFBs) within the fruiting bodies of H. bachu were confirmed by a polyphasic approach, including genomic sequencing, real-time quantitative PCR targeting the 16S rRNA gene, full-length and next-generation sequencing (NGS) of the 16S rRNA gene, and culture methods. The genera Stenotrophomonas, Variovorax, Acidovorax, and Pedobacter were abundant in the EFBs of fruiting bodies associated with three Populus hosts and were consistently present across different developmental stages. Notably, S. maltophilia and V. paradoxus were detected in high abundance, as revealed by full-length 16S rRNA sequencing, with S. maltophilia also isolated by culture methods. KO-pathway analysis indicated that pathways related to primary, secondary, and energy metabolism were predominantly enriched, suggesting these bacteria may promote H. bachu growth by producing essential compounds, including sugars, proteins, and vitamins, and secondary metabolites. This study confirmed the presence of EFBs in H. bachu and provided the first comprehensive overview of their structure, functional potential, and dynamic changes throughout fruiting body maturation, offering valuable insights for advancing the artificial domestication of this species.
