| highly conserved 5s ribosomal rna sequences in four rust fungi and atypical 5s rrna secondary structure in microstroma juglandis. | the 5s ribosomal rna nucleotide sequences of five basidiomycetous fungi, coleosporium tussilaginis , gymnosporangium clavariaeforme , puccinia poarum , endophyllum sempervivi and microstroma juglandis were determined. despite high differentiation in their host spectra the four rust species are highly conserved with respect to their 5s rrna sequences, which fit with the basidiomycete cluster 5 described by walker and doolittle (1). the sequences obtained from the first three rust fungi were prove ... | 1984 | 6728684 |
