Comparative Analysis of Sporulating and Spore-Deficient Strains of Agrocybe salicacola Based on the Transcriptome Sequences.

The large number of spores produced by edible mushrooms cause many problems, including causing lung disease, depleting natural genetic diversity, and reduced quality of fruiting bodies. Obtaining spore-deficient strains and understanding the underlying molecular mechanisms of such strains are important for breeding work. In this study, we crossed monokaryotic strains isolated from the edible fungi Agrocybe salicacola to obtain three spore-deficient strains with losses of the sterigmata on the surface of the lamella.
