Linking genotype to phenotype: a modelling framework for investigating individual and interacting mycelia
… complexity in individual and interacting fungal mycelia. A conceptual model identifying the minimal rule set responsible for complexity in terms of exhibited growth patterns is presented. The theoretical results replicate observed colony forms on agar and demonstrate that phenotype is sensitive …

A hybrid mathematical model of fungal mycelia: tropisms, polarised growth and application to colony competition
… a discrete network that represents the fungal mycelia and a continuous component to account for the continuous substrates and other compounds crucial to fungal growth and development. Key processes such as uptake, translocation and anastomosis are included in addition to the implementation of a …

Tumor Necrosis Factor-α Production By Murine Peritoneal Macrophages in Response to Candida Albicans Yeasts, Germ Tubes, and Mycelia
… of the organism forms germ tubes and eventually mycelia. The yeast form of the organism is enerally associated with the commensal organism and the mycelia is associated with systemic infection. Recognition of this pathogen by host immune cells such as macrophages causes the production of a …

The physiological response of the white-rot fungus, Schizophyllum commune to Trichoderma Viride, during interspecific mycelial combat
… and biochemical reactions in the interacting mycelia. Interspecific mycelial interactions have attracted extensive studies because of their potential applications in biological control, bio-pulping, screening for novel bioactive metabolites and enhancement of extracellular enzyme production. …

A greenhouse screening method for resistance to gray leaf spot in maize
… method with filter paper discs of C. zeaemaydis mycelia has been developed to evaluate corn germplasm for resistance to GLS. Mycelial inoculum obtained from cultures of mycelia in liquid malt media was pipetted at 100 ul samples onto each filter paper disc which was then adhered to the lower leaf …

Pisolithus Tinctorius Mycobiont Inoculations as a Factor in Performance of Containerized and Bare-Root Shortleaf Pine Seedlings on Lignite Minesoils in Panola County, Texas
… infestation with basidiospores and vegetative mycelia of the fungal symbiont Pisolithus tinctorius on ectomycorrhizae development of short leaf pine (Pinus echinata) seedlings grown in styroblock containers were tested in the greenhouse. These preliminary tests showed that both spores and …

The analysis of gene transcripts associated with conidiation in the insect pathogenic fungus, Metarhizium anisopliae /
… in the final stages of insect infection as the mycelia emerge from the insect cadaver. The genes associated with conidiation have not yet been studied in this fiingus. hi this study we used the PCR-based technique, suppression subtractive hybridization (SSH) to selectively amplify …

Continuum models for fungal growth
… hypha is only a few microns in diameter, yet mycelia can be kilometres across). Fungi are of fundamental importance to many natural processes: certain species have major roles in decomposition and nutrient cycling in the soil; some form vital links with plant roots allowing nutrient transfer. …

Mathematical and Experimental Investigation of Yeast Colony Development – A Model System for the Growth of Filamentous Fungi in Heterogeneous Environments
… as model organisms to study the growth of fungal mycelia. When environmental conditions are chosen appropriately, yeast colonies are built up of well separated individual cells. Thus, in contrast to fungal mycelia the translocation of nutrients and information within the colony can be neglected. …

Structure Elucidation of Bioactive Compounds Isolated from Endophytes of Alstonia scholaris and Acmena graveolens
… isolated from a stem of Alstonia scholaris, its mycelia and exudate extracted, and the extract assayed for growth inhibition of HeLa cancer cells in vitro. Several known compounds were isolated and identified based on NMR, infrared, and mass spectral data. The compounds identified are …

The use of hot water treatment by small holders for the control of alternaria alternata, the cause of black mould disease of tomato
… Conidia germination was more sensitive than mycelia growth to 50⁰C, but inhibition of both processes increased with the duration of time of treatment. The in-vitro hot water treatment of Alternaria alternata spores at 50⁰C i for 30 min significantly reduced the spore germination and mycelia …

Mechanisms of resistance to β-lactam antibiotics in Streptomycetes
… producing strains showed staining throughout the mycelia whereas in non β-lactamase producing strains staining only occurred in certain parts of the mycelia. Bocillin also revealed that in spores PBPs were located on both poles of the spores. Streptomyces coelicolor has the ability to grow at high …

Host and pathogen genomics: the molecular repertoire of soybean and Sclerotinia interactions
… inoculated soybean stems, and of S. sclerotiorum mycelia grown on liquid media. In addition to these global RNA expression studies, a gene-specific study was carried out on the role of a putative G protein-coupled receptor possibly implicated in the plant interactions with pathogens. The gene was …

Laccases from actinomycetes for lignocellulose degradation
… strains produced extensively branched substrate mycelia and aerial hyphae. Micromorphological characteristics were consistent with the assignment of these strains to the genus Streptomyces. Isolates were found to be mesophiles, with growth occurring in a temperature range of 16 and 45°C. Optimal …

Biology of Fungi on Plants in the Sub-Antarctic
… Mucor hiemalis, plus a large number of sterile mycelia. As leaves aged, their water contents decreased and levels of soluble carbohydrates were reduced. On falling to the litter layer, leaf carbohydrate levels declined further, but water contents were increased. The litter mycoflora was markedly …

MECHANICAL ABRASION AND ELECTROPORATION IN THE TRANSFORMATION OF INTACT PLEUROTUS OSTREATUS HYPHÆ and NUTRIENT-DEPENDANT RESISTANCE TO HYGROMYCIN B
… method of transforming of intact hyphæ. Mycelia, which are not capable of being transformed via electroporation due to interference by the cell wall, were abraded in an attempt to mechanically degrade the cell wall prior to electroporation. An electroporation field strength of 12,500 V/cm …

Unraveling the role of the antifungal peptide AnAFP in Aspergillus niger through a systems biology perspective
… Moreover, the expression of anafp in A. niger mycelia was examined for signs of autophagy and apoptosis, to determine whether the observed reduction in growth results from cell death. In line with this analysis, the subcellular distribution of AnAFP -eGFP was explored using live-cell confocal …
