The initiation of sporangiophores of Phycomyces was analyzed under oxygen-limiting conditions. Mutants lacking β-carotene have a higher oxygen threshold than the wild type depending on the residual amount of β-carotene. The supersensitivity to low oxygen tension is specific for sporangiophore initiation and can be suppressed by addition of either retinal, retinol or retinol acetate to the medium. It is suggested that retinol is a natural regulator of differentiation in Phycomyces.
我们在缺氧条件下分析了藻菌的游动孢子囊梗的起始。β-胡萝卜素缺失突变体的氧阈比野生型高，这取决于β-胡萝卜素的残留量。对低氧张力的超敏感性是游动孢子囊梗起始的特异性，并且可以通过向培养基中添加视黄醛、视黄醇或视黄醇乙酸酯来抑制。这表明视黄醇是藻菌分化的天然调节剂。
