RESUMO

The nucleotide sequences of the 5S rRNAs of the oomycete water molds Saprolegnia ferax and Pythium hydnosporum and of the chytrid water molds Blastocladiella simplex and Phlyctochytrium irregulare were determined by chemical and enzymatic partial degradation of 3' and 5' end-labelled molecules, followed by gel sequence analysis. The two oomycete sequences differed in 24 positions and the two chytrid sequences differed in 27 positions. These pairs differed in a mean of 44 positions. The chytrid sequences clearly most resemble the sequence from the zygomycete Phycomyces, while the oomycete sequences appear to be allied with those from protozoa and slime molds.
