Abstract

Polyamine, RNA, DNA, and protein levels were determined during the germination of Rhizopus stolonifer and Botryodiplodia theobromae spores. Putrescine and spermidine were the only polyamines detected in the spores. In both fungi, the increases in spermidine and RNA roughly paralleled one another. In addition, a large transitory increase in the putrescine pool size was observed in R. stolonifer. Quantitatively, the biosynthetic patterns observed in the two fungi were quite different. In R. stolonifer, macromolecular and polyamine syntheses were continuous from the onset of germination, resulting in several fold increases by the time of germ tube formation. These syntheses were delayed in B. theobromae, however; consequently, the macromolecular and polyamine contents only doubled by the time of germ tube formation.
