Abstract

SUMMARY: Exhaustive alkali and acid extraction of zygospores leaves a residue that is chemically very similar to higher plant and synthetic sporopollenins. This Mucor sporopollenin is probably a component of the outer part of the zygospore wall. The incorporation of radioactive acetate, mevalonate and -carotene suggests that it is biosynthesized by an oxidative polymerization of -carotene. Thus sporopollenin formation is probably a role for the increased carotenogenesis observed during sexual reproduction of many members of the Mucorales.
