Two-factor crosses between the non-allelic spore colour mutants r2 and lu of the fungus Sordaria macrospora were used to investigate the effect of clinostatic rotation (= simulated weightlessness) on crossover frequencies. The experiment wa...
Effect of microgravity, temperature, and concentration on fibrin and collagen assembly [0.03%]
微重力、温度和浓度对纤维蛋白和胶原组装的影响

F Croute et al.
In vitro human dermal fibroblasts were submitted to normal gravity (1 g) or to chronic hypergravity ranging from 2 to 20 g for 8 days. Changes only appeared above 15 g. The majority of 20 g-subjected cells showed fine filipods in the shape ...
Electrofusion of plant cell protoplasts under microgravity--a D-2 spacelab experiment [0.03%]
