Plant pathology

A pressure cell a fungus uses to break into a host

An appressorium is the specialised infection cell that many plant-pathogenic fungi form at the end of a germ tube: it attaches flat to the host surface, then generates enormous internal turgor pressure that drives a narrow penetration peg through the intact cuticle and cell wall into the tissue below. In the rice blast fungus the pressure reaches levels far beyond those of ordinary cells, making the appressorium a near-mechanical breaching tool. Howard and Valent's Breaking and entering measured this process in Magnaporthe grisea. The referent is a fungal penetration structure, central to how foliar diseases establish.[1]

Unit
The turgor pressure generated and the success of host penetration
Recovery means
Not applicable
Measured by
Assessed by appressorial turgor (for example with incipient-cytorrhysis assays) and by penetration frequency into the host
