CohortP. capsici susceptible tomato plants (S. lycoperisum cv. Moneymaker) were grown in a greenhouse at 22-25 oC with 16 h light. P. capsici strains (LT6535 and LT1534) were grown on V8 agar medium in the dark at 25 oC for 3 days and subsequently at 22 oC in the light to induce sporangia formation. To harvest sporangia and induce zoospore release, plates were flooded with ice cold water, agitated with a plate spreader to dislodge sporangia, and the sporangia suspension incubated at 22 oC in the light until motile zoospores were released. Zoospores were diluted to a concentration of 1 x 105 spores ml-1 and used to inoculate 4-5 week old detached tomato leaves by placing 20 µl droplets onto the abaxial surface. Leaves were kept in a box lined with moist tissue to create a humid environment, and incubated at 22 oC with a 16 h photoperiod for the duration of the experiment. For lesion measurements, the diameter of the lesion was measured with a ruler. For RNA or protein extraction from infected leaf tissue, leaf discs containing the inoculation site were collected using a core borer (5 mm diameter) and flash frozen in liquid nitrogen before extraction.

Disease Introduction MechanismPlant pathogenic oomycetes cause devastating diseases on a wide range of plants important in food production, forestry and natural ecosystems. For example, Phytophthora infestans, the causal agent of late blight on potato and tomato, continues to cause multi-billion dollar losses each year (Birch and Whisson 2001; Nowicki et al. 2012). Other economically devastating pathogens in the genus include P. sojae and P. capsici, the major disease- causing agents of soybean and pepper, respectively. The vast economic damage that Phytophthora pathogens cause, have been and continue to drive efforts to understand the basic processes involved in pathogenicity.
