title: DNA methylation and polyamines in regulation of development of the fungus Mucor rouxii.
abstract: DNA from intact or spherically growing spores of Mucor rouxii is highly methylated, whereas DNA from germlings has low levels of methylation. DNA from spores incubated with hydroxyurea or 1,4-diaminobutanone is also highly methylated. The reversal of the effect of 1,4-diaminobutanone by azacytidine correlated with DNA hypomethylation. These data suggest that the change in growth pattern from spherical to polarized correlates with the degree of DNA methylation and that this, in turn, may be controlled by polyamine levels.
