摘要

在两种抗菌剂的作用下生长的丛木会引起相反的形态发生变化:紫杉醇维持了菌丝的营养伸长生长，从而阻止了它们向雌雄配子体的顶端分化;诺可达唑阻止胚管的生长，诱导菌丝上胚根的出现，并导致菌丝内细胞核位置的改变。紫杉醇的存在阻止了诺可达唑引起的形态发生紊乱。

Morphogenetic changes provoked by two antimicrotubular drugs with opposite effects during the developmental cycle of Allomyces arbuscula

Opposite morphogenetic changes have been provoked by growing A. arbuscula in the presence of two antimicrotubular agents: taxol maintained vegetative hyphal elongation growth and thereby prevented their apical differentiation into couples of male-female gametangia; nocodazole prevented germ tube outgrowth, induced emergence of epihyphal rhizoids and led to altered positioning of intrahyphal nuclei. Primary hyphal growth in the presence of taxol prevented the nocodazole-induced morphogenetic disturbance.
