“…Mitchell et al (1991) established that solid media fermentations are geometrically complex because of the heterogeneity of the spatial distribution of the system components. Fariña et al (1997), Bezzi and Ciliberto (2004) and Mezkauskas et al (2004) claimed that when a colony grows on solid medium, its radius increased linearly with time. The expansion rate is specific for the organism and the culture conditions.…”

“…At the colony growing front, tips are initially free to grow. Therefore, tip growth is controlled by the local biomass surface density, incorporating a bias to the local growth rate (Mezkauskas et al, 2004).…”

“…In terms of previous model classification [19], it is a lattice-free model where the mycelial network is not constrained to a predetermined grid or lattice. Our model is similar to previous approaches for other filamentous fungi [50,51] regarding that the fungal network (like the root system) is represented by a collection of line segments as well as tips that can extend with time. At each time step, there is the possibility of hyphal fusion, and a reorientation of the direction of growth.…”

Development of arbuscular mycorrhizal fungal colonization of roots and the surrounding soil is the central process of mycorrhizal symbiosis, important for ecosystem functioning and commercial inoculum applications. To improve mechanistic understanding of this highly spatially and temporarily dynamic process, we developed a three-dimensional model taking into account growth of the roots and hyphae. It is for the first time that infection within the root system is simulated dynamically and in a spatially resolved way. Comparison between data measured in a calibration experiment and simulated results showed a good fit. Our simulations showed that the position of the fungal inoculum affects the sensitivity of hyphal growth parameters. Variation in speed of secondary infection and hyphal lifetime had a different effect on root infection and hyphal length, respectively, depending on whether the inoculum was concentrated or dispersed. For other parameters (branching rate, distance between entry points), the relative effect was the same independent of inoculum placement. The model also indicated that maximum root colonization levels well below 100%, often observed experimentally, may be a result of differential spread of roots and hyphae, besides intrinsic plant control, particularly upon localized placement of inoculum and slow secondary infection.

“…Th e Neighbour-Sensing model has been used in a series of experiments (Meškauskas et al, 2004b) to show that complex fungal fruit body shapes can be simulated by applying the same regulatory functions to all of the growth points active in a structure at any specifi c time-the shape of the fruit body emerges as the entire population of hyphal tips respond together, in the same way, to the same signals.…”

ABSTRACT:Research done over the last century has persistently indicated major diff erences between fungi, animals, and plants. Unfortunately, for most of that time fungi have been considered, quite erroneously, to be closely related to plants; as observations have been constrained to comply with this fundamental error, a proper appreciation of fungal developmental biology has been seriously inhibited. During the fi nal quarter of the 20t century, the phylogenetic status of the true fungi as an independent Kingdom of eukaryotes became clear. In this review, I bring together some of the observations, old and recent, that contribute to our current understanding of the way that fungi construct multicellular structures.
