Respiration and gene expression in germinating ascospores of Neurospora tetrasperma.
Cellular proteins were not synthesized by germinating ascospores of Neurospora tetrasperma until 90 min after spore activation. Nevertheless, immediately after activation these ascospores developed a cyanide-sensitive respiration which increased throughout this 90-min period. At 90 min the respiratory rates accelerated rapidly, protein synthesis was initiated, and transcripts for a subunit of the mitochondrial ATPase, employed here as a representative mRNA, began to accumulate.
