“…The reason for this is that the hydrostatic turgor pressure in the cell is not exerted against the external substrate unless the wall relaxes and has some freedom to expand. Only in some environmental conditions was this fraction found to increase to up to 54% in fungal hyphae (41). The fact that our value of 0.15 MPa for the normal pressure in Camellia pollen tubes is very close to the typical turgor pressure of pollen tubes of similar size [lily, 0.2 MPa (7)] suggests that the compliance of the cell wall in the apical region of the pollen tube is very high compared with the fungal hyphae measured so far, thus releasing much of the turgor-induced pressure to the outside, enabling optimal force exertion.…”

Tip-growing cells have the unique property of invading living tissues and abiotic growth matrices. To do so, they exert significant penetrative forces. In plant and fungal cells, these forces are generated by the hydrostatic turgor pressure. Using the TipChip, a microfluidic lab-on-a-chip device developed for tip-growing cells, we tested the ability to exert penetrative forces generated in pollen tubes, the fastest-growing plant cells. The tubes were guided to grow through microscopic gaps made of elastic polydimethylsiloxane material. Based on the deformation of the gaps, the force exerted by the elongating tubes to permit passage was determined using finite element methods. The data revealed that increasing mechanical impedance was met by the pollen tubes through modulation of the cell wall compliance and, thus, a change in the force acting on the obstacle. Tubes that successfully passed a narrow gap frequently burst, raising questions about the sperm discharge mechanism in the flowering plants.

“…Lucking et al (2009), in their comparison of fossil and molecular dating systems of fungal evolution, state that "all dating estimates show that the evolution of filamentous fungi occurred much later than the origin of the fungal lineage itself, suggesting that for a long time after their origin, fungi were heterotrophic, unicellular, flagellate, aquatic organisms." An option for the hyphal form, whose adaptive utility is shown by convergent evolution of hyphae in fungi and oomycete water molds (Money et al 2004), may have evolved when fungi colonized land as plant symbionts (Redecker et al 2000;Heckman et al 2001;Lucking et al 2009). Morphogenesis also contributes to protection against amoeboid cell predation.…”

“…Nevertheless, in terms of their biological activity, they demonstrate convergent evolution with fungal plant pathogens. For example, oomycetes share a filamentous, osmotrophic growth habit and are capable of invasive growth and colonization of living plant tissue (Money et al 2004).…”

The recent proliferation of genome sequencing in diverse fungal species has provided the first opportunity for comparative genome analysis across a eukaryotic kingdom. Here, we report a comparative study of 34 complete fungal genome sequences, representing a broad diversity of Ascomycete, Basidiomycete, and Zygomycete species. We have clustered all predicted protein-encoding gene sequences from these species to provide a means of investigating gene innovations, gene family expansions, protein family diversification, and the conservation of essential gene functions-empirically determined in Saccharomyces cerevisiae-among the fungi. The results are presented with reference to a phylogeny of the 34 fungal species, based on 29 universally conserved protein-encoding gene sequences. We contrast this phylogeny with one based on gene presence and absence and show that, while the two phylogenies are largely in agreement, there are differences in the positioning of some species. We have investigated levels of gene duplication and demonstrate that this varies greatly between fungal species, although there are instances of coduplication in distantly related fungi. We have also investigated the extent of orthology for protein families and demonstrate unexpectedly high levels of diversity among genes involved in lipid metabolism. These analyses have been collated in the e-Fungi data warehouse, providing an online resource for comparative genomic analysis of the fungi.
