Serpula himantioides its relation to "S. lacrymans." "Serpula himantioides" has a heterothallic tetrapolar mating system. This means it requires the growth and conjugation of two mating types, determined by the expression of one or more alleles of two unlinked mating loci, for sexual reproduction. "Serpula himantioides" is commonly found in the wild, while "S. lacrymans" is rarely found in the wild and is generally found on lumber in buildings and construction. Serpula himantioides Serpula himantioides is a species of fungus that causes damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales. It has been found
Serpula lacrymans of 13805 genes. "S. lacrymans"' genome encodes six annotated polyketide synthases (PKS1-PKS6), 15 nonribosomal peptide synthetases (NPS1-NPS4, NPS7, NPS13-NPS15, NPS17, and NPS18), and two hybrids thereof (NPS6, NPS8, and NPS16). Additionally, the genome encodes for various putative adenylate-forming reductases (NPS5, NPS9-NPS12) (Eastwood et al., 2011). "NPS3" was overexpressed in E. coli and characterized as an atromentin/quinone synthetase that catalyzes the formation of atromentin, similar to GreA; InvA1,2 and 5; and AtrA from Suillus grevillei, Tapinella panuoides, Paxillus involutus, respectively. "NPS3" and its adjacent clustered aminotransferase gene ("AMT1") were also found to be up-regulated during co-incubation with bacteria (Tauber et al.,
