1
Biosynthesis and processing of cytoplasmic mRNA from beterogenous nuclear RNA (hn-RNA)ia Aspergiius phoenicis were studied by 3H-aridine labeling and synchronous culture techniqua during their life cycle.
Incorporation of 3H-uridiue into hn-RNA and mRNA were most rapid in vesicle-phialide formation stage and diminished in hyphal growth stage. The processing of cytoplasmic mRNA from ha-RNA was proceeded more rapidly in byphal growth and conidiophore formation stages than in cosidia and vesicle-phiaiide formation stages. The specific radioactivities of ha-RNA sad mRNA were very high in veside-phiaiide formation stage.
