Serpula lacrymans Serpula lacrymans Serpula lacrymans is one of the fungi that cause damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales. The species was first described under the name "Boletus lacrymans" by Franz Xavier von Wulfen in 1781. It was transferred to the genus "Serpula" by Petter Karsten in 1884. The specific epithet is derived from the Latin words "serpula" for "creeping" (as in a serpent) and "lacrymans", meaning "making tears". "Serpula lacrymans" has a preference for temperatures of but can survive any temperature from . It is not clear how much light is
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.,
