Effects of salinity on P. ramorum growth, survival, and sporulation

Several species of Phytophthora can survive and sporulate in saline environments, but it is not known whether P. ramorum mycelial growth and sporulation as independent study projects for Dr. Erica Cline’s Environmental Microbiology class (TESC 378).

Mycelial growth was partially inhibited with increasing salinity. Chlamydospore production on rhododendron leaf discs tended to increase, especially in the NA2 lineage.

Two women standing next to each other by a metal countertop. The one closer to the camera is holding an Erlenmeyer flask with water in it. The other woman is holding a graduated cylinder. On the counter in front of the second woman is a number of smaller Erlenmeyer flasks, some of which contain an amber liquid.
