Fungal cell biology 2

• mechanism of spore discharge in basidiomycetes

  • Two water drop are formed due to secretion of mannitol and other hygroscopic sugars on the surface of the spore
  • Buller’s drop increases in size due to recruitment of atmospheric water
  • Sudden change of centre of gravity by fusion of both drops create a propulsive force
• spore discharge in ascomycetes

  • Mold fungi release massive numbers of spores into the air
  • This mechanism is very different, as it involves turgor pressure that is builds up by within the ascus, and a sudden burst
  • Pressure builds up to 100-700 kPa
  • Shooting distance: centimetres to up to 2 meters
• do fungi have intermediate filaments

  no
• what is chromosome motility driven by

  nuclear pore motility
