Transcriptomic and Ultrastructural Signatures of K⁺-Induced Aggregation in Phytophthora parasitica Zoospores.

ABSTRACT: Most pathogenic oomycetes of the genus Phytophthora spread in water films as flagellated zoospores. Zoospores perceive and produce signals attracting other zoospores, resulting in autoaggregation in vitro or biofilm formation on plant surface. The mechanisms underlying intercellular communication and consequent attraction, adhesion and aggregation are largely unknown. In Phytophthora parasitica, the perception of a K⁺ gradient induces coordinated motion and aggregation. To define cellular and molecular events associated with oomycete aggregation, we combined transcriptomic and ultrastructural analyses. Results indicate involvement of electroception in K⁺ sensing. They establish that the transcriptome repertoire required for swimming and aggregatio
