摘要

戴维斯,r.h.和里斯托,j.l. 1995。粗神经孢子虫多胺途径的渗透效应。真菌学学报,19(3):314-319。在细菌、哺乳动物和某些植物中,多胺合成酶鸟氨酸脱羧酶(ODC)的诱导及其产物腐胺的积累是在细胞渗透操作之后发生的。至少在某些情况下,这种反应对于生存是必不可少的。我们希望确定粗神经孢子虫的多胺途径是否在高渗或低渗条件下受到调节。与大多数其他种类生物的ODC不同,无论是在突然转变期间还是在稳态状态下,N. grassa酶和腐胺的积累似乎对这些条件相对漠不关心。我们得出的结论是,其他渗透调节或耐受机制已经在N. crassa和其他真菌中进化,从而消除了对腐胺积累的需要。

Osmotic Effects on the Polyamine Pathway of Neurospora crassa

Davis, R. H., and Ristow, J. L. 1995. Osmotic effects on the polyamine pathway of Neurospora crassa. Experimental Mycology 19, 314-319. In bacteria, mammals, and certain plants, the induction of the polyamine synthetic enzyme, ornithine decarboxylase (ODC), and the accumulation of its product, putrescine, follows osmotic manipulations of cells. In at least some of these cases, this response is indispensable for survival. We wished to determine whether the polyamine pathway of Neurospora crassa was regulated in response to hyper- or hypoosmotic conditions. Unlike ODC of most other classes of organisms, the N. crassa enzyme and the accumulation of putrescine appears to be relatively indifferent to these conditions, either during sudden transitions or in steady-state. We conclude that other mechanisms of osmotic adjustment or tolerance have evolved in N. crassa and perhaps other fungi that obviate the need for putrescine accumulation.
