Abstract
This study was carried out to elucidate the poorly understood processes of arthroconidiation through coremium formation using Pleurotus cystidiosus subsp. abalonus. The coremia exclusively produced dikaryotic arthroconidia with the remnant of a clamp connection. Cells in the subapical zone of the hyphal bundle reduced their length by division before arthroconidiation. Approximately 400 000 arthroconidia were produced by a coremium in 1 day, with constant productivity over a 2-week period. Continuous cell extension and division in the coremium stipe supplied cells for arthroconidiation at the coremium apex, which is surrounded by a liquid droplet (coremioliquid). Maintenance of moisture with coremioliquid was necessary for arthroconidiation. The coremioliquid formation was performed by active liquid transportation in the hyphae, a process that was blocked by the microtubule depolymerization agent thiabendazole.
