Crystals of the basic elicitin secreted by Phytophthora cryptogea have been obtained by the hanging-drop method of vapor diffusion from sodium chloride solutions. The crystals belong to the tetragonal space group P4(1)22 (or enantiomorph P4(3)22), with unit cell dimensions a = b = 47 A, c = 137 A and probably contain two molecules per asymmetric unit. The crystals are very stable to X-rays and diffract to 2.2 A resolution on a synchrotron radiation source.

Sterols are vital nutrients and signals for eukaryotic organisms. Mammalian cells are known to sense and respond to sterol status changes to maintain them within strict limits, a process associated with various human diseases. However, this process is not understood in oomycete pathogens, most of which are sterol auxotrophic and must obtain sterols from host plants.

Plants have developed intricate immune mechanisms to impede Phytophthora colonization. In response, Phytophthora secretes RxLR effector proteins that disrupt plant defense and promote infection. The specific molecular interactions through which Phytophthora RxLR effectors undermine plant immunity, however, remain inadequately defined.

is a plant pathogenic oomycete that causes crown rot in strawberry leading to significant economic losses every year. To invade the host, secretes an arsenal of effectors that can manipulate host physiology and impair its defense system promoting infection. A transcriptome analysis was conducted on a susceptible wild strawberry genotype () 48 hours post inoculation with to identify effectors expressed during the early infection stage.
