Manipulierung der Zellgrösse von Diatomeen im Experiment1

摘要: Abstract Diatoms usually undergo a decrease in size concomitant with cell division. Because the developmental and physiological faculties of diatoms are dependent on size, ability to manipulate would be valuable for experimental purposes. Although enlargement cells can obtained by auxospore formation, latter, as an essentially sexual process (in diploid organism), alters genetical make-up strain. Methods carry out vegetatively therefore required fact applied routinely Marburg laboratory. Their use is described discussed. They not general application, however, but always some cooperation object its specific reactions. If there cooperation, Stephanopyxis turris, Bellerochea malleus, Streptotheca, Lithodesmium, 5 species Biddulphia, Grammatophora marina, Rhabdonema arcuatum, Achnanthes longipes others, vegetative induced nutriti...
