appressorium การใช้

• The spores produce an appressorium which in turn produces a penetration peg.
• It infects plants with an appressorium.
• There then follows elongation of the germ tubes, whose apical section later differentiates into an appressorium.
• The " appressorium " is the swollen structure preceding penetration through a host cell wall.
• Appressorium formation begins when the tip of the germ tube ceases polar growth, hooks, and begins to swell.
• The chemical inhibits the conidial germination and appressorium formation of the rice blast fungus " Magnaporthe oryzae ".
• This hypha grows from bottom of the appressorium and works it s way through an intercellular junction of two epidermal cells.
• The mechanical pressure exerted by the appressorium is generated from physiological processes that increase intracellular turgor by producing osmolytes such as glycerol.
• Germ tubes give rise to appressorium which form haustorium and allow the pathogen to extract nutrients without penetrating the host s cell membrane.
• Appressorium development involves a number of steps : nuclear division, first septum formation, germling emergence, tip swelling and second septum formation.
• This glycerol accumulation generates high turgor pressure in the appressorium, and melanin is necessary for maintaining the glycerol gradient across the appressorium cell wall.
• This glycerol accumulation generates high turgor pressure in the appressorium, and melanin is necessary for maintaining the glycerol gradient across the appressorium cell wall.
• Turgor pressure increases inside the appressorium and a penetration hyphae emerges at the pore, which is driven through the plant cuticle into the underlying epidermal cells.
• Instead, " Rickenella " produces a small appressorium or no appressoria and penetrates the rhizoids of its moss hosts, growing within the cells.
• Cellular glycerol concentration sharply increases during spore germination, but it rapidly decreases at the point of appressorium initiation, and then gradually increases again during appressorium maturation.
• Cellular glycerol concentration sharply increases during spore germination, but it rapidly decreases at the point of appressorium initiation, and then gradually increases again during appressorium maturation.
• It can either enter through the stomata, or penetrate directly through the top of the leaf, using its appressorium, infecting the leaf within 12 hours.
• 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.
• 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.
• They are able to detect other fungi and grow towards them, they then bind to the hyphae of other fungi using lectins on the host fungi as a receptor, forming an appressorium.
