Two complementary DNA (cDNA) libraries were constructed from tissues isolated from primordia and basidiomes of Agaricus bisporus to characterize genes involved in mushroom development. Using single-pass sequencing of 869 cDNA clones, we found 477 expressed sequence tags (ESTs), including 466 not previously described in the databases for A. bisporus. A BLASTX search revealed that 374 ESTs had similarities with protein sequences available from databases; 193 of these ESTs were categorized according to their putative function. Most ESTs were assigned to one of four roles: metabolism (23%), cell structure (15%), cell growth and division (12%), and protein destination and storage (10%). The remaining ESTs with putative homologues were classified in 10 additional categories. Many ESTs could not be functionally assigned. Based on redundancy levels, at least 4 ESTs were preferentially expressed in each tissue type. Sequence analysis also suggested the presence of paralog tyrosinase genes in the A. bisporus genome.
