Sexual reprduction of paramecia have been accomplished through conjugation between
individuals which have opposite mating type substances on their cilia when they were
starved. Using selfing clone in which mating takes place, I examined whether a mating
type change in individual cells required new protein and new mRNA synthesis or not
and also whether there is a precursor relationship between both of the complementary
mating type substances in their synthetic pathway. I found that
1. Mating type change needs new protein(s) and new mRNA synthesis.
2. Mating type substances are synthesized sequentially from mating type ?? to ??
3. There might be a common precursor pool from which the mating type ?? substance
is synthesized and then complementary mating type ?? is formed by addition of small
group to the mating type ¥¹¥² substance.
