Why algae attaches to plants
Hi Tom,
If I read that correctly, I can expect more algal growth on the glass and substrate than on the plants? Regards David wrote in message oups.com... http://www.blackwell-synergy.com/doi...6.1991.00196.x Regards, Tom Barr |

That much seems to be supported. Regards, Tom Barr |

I get the impression that algae grew bettter on the non-plant media than on plants unti the leaves got old but that the difference between old and new leaf algae growth was not well understood - just a hypothesis at this juncture. -- Need Mercedes parts? http://parts.mbz.org Richard Sexton | Mercedes stuff: http://mbz.org 1970 280SE, 72 280SE | Home pages: http://rs79.vrx.net 633CSi 250SE/C 300SD | http://aquaria.net http://killi.net |

While a hypothesis, it's still a good one that matches well and there is correlation to support it, but more test are required. If you could do something to disrupt the target for the alga's attachment sensory to cuticles, then no algae would attach to plants. Using a molecular mutant approach, this would/could confirm it.
