Phytophthora parasitica: a model oomycete plant pathogen.

Meng Y, Zhang Q, Ding W, Shan W - Mycology (2014)

Bottom Line: Tremendous progress has been achieved in recent years in diversity, evolution and lifestyles of oomycete plant pathogens, as well as on the understanding of genetic and molecular basis of oomycete-plant interactions.Phytophthora parasitica is a soilborne pathogen with a wide range of host plants and represents most species in the genus Phytophthora.In this review, we present some recent progress of P. parasitica research by highlighting important features that make it emerge as a model species of oomycete pathogens.

ABSTRACT
Oomycetes are eukaryotic microorganisms morphologically similar to but phylogenetically distant from true fungi. Most species in the genus Phytophthora of oomycetes are devastating plant pathogens, causing damages to both agricultural production and natural ecosystems. Tremendous progress has been achieved in recent years in diversity, evolution and lifestyles of oomycete plant pathogens, as well as on the understanding of genetic and molecular basis of oomycete-plant interactions. Phytophthora parasitica is a soilborne pathogen with a wide range of host plants and represents most species in the genus Phytophthora. In this review, we present some recent progress of P. parasitica research by highlighting important features that make it emerge as a model species of oomycete pathogens. The emerged model pathogen will facilitate improved understanding of oomycete biology and pathology that are crucial to the development of novel disease-control strategies and improved disease-control measures.

Figure 2: The life cycle of Phytophthora parasitica.

Mentions: The typical Phytophthora life cycle includes both asexual and sexual phases. The life cycle of P. parasitica is shown in Figure 2. The hyphae are hyaline and aseptate, sometimes with hyphal swellings. P. parastica produces asexual sporangia, zoospores and chlamydospores. The sporangia are difficult to be released from the hyphae, which is different from the released, airborne sporangia of P. infestans. Zoospores are produced by the sporangia and are wall-less cells with two flagella, which enable them to swim. Chlamydospores are thick-walled, multinucleated asexual spores, usually produced at the tips or in the middle of hyphae. P. parasitica is predominantly het-erothallic, requiring A1 and A2 mating types for the production of oospores (Ko 1981).
