Nonchemical signals used for host location and invasion by fungal pathogens.
Not all aspects of the interactions between fungal pathogens and their hosts are mediated by specific chemical signals, but until recently the functional significance of nonchemical cues (such as local electrical fields, pH gradients and host surface topography) was obscure. Recent studies of the mechanisms underlying fungal tropisms and taxes to such cues have revealed novel architectural and physiological properties of the fungal cells that contribute to their success as pathogens.
