Carotenoid mutants of Gibberella fujikuroi

The orange pigment neurosporaxanthin colours the mycelia of wild Gibberella fujijuori (Fusarium monifliforme) grown in the light, but is barely detectable in the dark. We have isolated carotenoid mutants from conidia exposed to N-methyl-N′-nitro-N-nitroso-guanidine and other mutagens. Specific blocks in the pathway are represented by white mutants… CONTINUE READING
