part of developmental process involved in reproduction ascospore wall assembly spore wall assembly GO:0030476 biological_process GO:0007152 The aggregation, arrangement and bonding together of a set of components to form an ascospore wall. During sporulation in Ascomycota, each ascospore nucleus becomes surrounded by a specialized spore wall, formed by deposition of spore wall components in the lumenal space between the outer and inner leaflets of the prospore membrane. An example of this process is found in Saccharomyces cerevisiae. spore wall assembly ascospore wall biogenesis fungal-type cell wall assembly meiotic cell cycle process
