New information on the mechanism of forcible ascospore discharge from Ascobolus immersus.

Abstract

Many ascomycete fungi spurt their spores from asci pressurized by osmosis. This paper explores the details of this process in the coprophilous species Ascobolus immersus, through a combination of biomechanical and biochemical experiments, and mathematical modeling. A. immersus forms large asci that expel 8 spores as a single, mucilage-embedded projectile… (More)
