Spore germination and zygote formation inSaccharomyces carlsbergensis

  • Published:
Proceedings / Indian Academy of Sciences

Summary

1. A pictographic summary of the variations observed during spore germination, differences in the activity of the spores during pair-wise conjugation and the mode of budding by the spore zygotes is presented.

2. Rarely the spores are capable of direct germination. When all the four spores in an ascus are germinating directly their development is not synchronous.

3. Spores germinating directly become indistinguishable from vegetative cells when they start proliferation and hence cannot be confused with waisted spore zygotes, retaining their characteristic shape even after producing a few buds, during investigations on the structure of the nucleus in living zygotes.
