* U. linza is a green macroalga (seaweed) that is widely used as a model organism in marine biofouling studies. Reproduction is facilitated by the release of motile, pear-shaped zoospores, 5-8 μm in length that are surrounded by a lipoprotein plasma membrane, ie there is no polysaccharide cell wall. Spores have a negative zeta potential, are negatively phototactic and also respond to a number of surface cues eg wettability, charge and topography. Settlement involves rapid secretion of a glycoprotein adhesive and permanent attachment to the substratum, retraction of the four flagella resulting in loss of motility, and the formation of a polysaccharide-rich cell wall. Permanently attached zoospores are rounded and typically 4-5 μm in diameter. Settlement (ie permanent attachment) is followed by germination of the attached spore, cell division and eventually the formation of a new adult plant<ref name="ref1"/> <ref name="ref2"/> .

Description

Ulva linza-1.jpg
  • Ulva linza is a green macroalga (seaweed) that is widely used as a model organism in marine biofouling studies, which reproduces by production of spores that rapidly develop into sporelings. It is well known for its distribution in all aquatic habitats including freshwater, brackish environments, marine and fully saline environments throughout the warm temperate and tropical regions of the world. It must cope with more dramatic changes than land plants because of tidal changes in light intensity, temperature, salinity, and wave action and with the biotic stresses characteristic of dense coastal ecosystems[1][2].
