modeling the spread of phytophthora.we consider a model for the morphology and growth of the fungus-like plant pathogen phytophthora using the example of phytophthora plurivora. here, we are utilizing a correlated random walk describing the density of tips. this random walk incorporates a delay in branching behavior: newly split tips only start to grow after a short while. first, we question the effect of such a delay on the running fronts, for uniform- as well as non-uniform turning kernels. we find that this delay primarily infl ...201122159730
re-evaluation of phytophthora citricola isolates from multiple woody hosts in europe and north america reveals a new species, phytophthora plurivora sp. nov.during large-scale surveys for soilborne phytophthora species in forests and semi-natural stands and nurseries in europe during the last decade, homothallic phytophthora isolates with paragynous antheridia, semipapillate persistent sporangia and a growth optimum around 25 degrees c which did not form catenulate hyphal swellings, were recovered from 39 host species in 16 families. based on their morphological and physiological characters and the similarity of their its dna sequences with p. citri ...200920198142
