A number of ribonucleic acids initiated synthesis during the first 15 min of germination of Rhizopus stolonifer sporangiospores. They included ribosomal, 5S, and transfer RNA, and a heterogeneously-sedimenting fraction that composed about 5% of the total cellular RNA; this fraction was unmethylated, did not compete with ribosomal RNA for hybridization to DNA, and was bound to poly dT-cellulose in a manner characteristic of RNAs containing polyadenylate segments. The nearly simultaneous onset of synthesis of the various RNAs with germination contrasts with the sequential onset of RNA synthesis reported for other fungal spores.
