These zoospores then swim in a film of water to a suitable site and each one produces a germ tube-like that of the sporangium-that penetrates the stoma.
42.
If the sporangia germinate through the development of a vegetative germ tube, the germ tube will then develop into a mycelium and go on to produce many sporangia and sporangiospores.

If the sporangia germinate through the development of a vegetative germ tube, the germ tube will then develop into a mycelium and go on to produce many sporangia and sporangiospores.
44.
The contents of the spore are then mobilized into the developing appressorium, a septum develops at the neck of the appressorium, and the germ tube and spore collapse and die.
45.
The germ tube of " P . macularis " plays an important role in determining the pathogen s viability, because it can penetrate its host in approximately 15 hours.
46.
A germ tube emerges from a macroconidium through the surface of a honeydew drop and a secondary conidium of an oval to pearlike shape is formed, to which the contents of the original macroconidium migrates.
47.
In most species, there is a single cell inside the spore, and a slender extension of this cell called the " germ tube " germinates from the proximal side of the spore.
48.
Following spore attachment and germination on the host surface, the emerging germ tube perceives physical cues such as surface hardness and hydrophobicity, as well as chemical signals including wax monomers that trigger appressorium formation.
49.
Another type of cell is a conidial anastomosis tube ( CAT ); these differ from germ tubes in that they are thinner, shorter, lack branches, exhibit determinate growth and home toward each other.
50.
A "'germ tube test "'is a diagnostic test in which a sample of fungal spores are suspended in animal serum and examined by microscopy for the detection of any germ tubes.
