The ribosomal DNA (rDNA) units in the glomalean zygomycete fungus Scutellospora castanea were analyzed. Dot-blot assays allowed an estimation of 75 copies per genome. After constructing a genomic library in a phage lambdaEMBL3 vector, 13 rDNA clones were screened and explored. PCR experiments confirmed their nature and allowed homologous probes to be obtained. Restriction-fragment length polymorphism (RFLP) analysis and hybridizations with 18 s and 25 s probes allowed their grouping into nine… CONTINUE READING
