Analysis of the Phlebiopsis gigantea Genome, Transcriptome and Secretome Provides Insight into Its Pioneer Colonization Strategies of Wood

P. gigantea transcriptome.

Scatterplot (A) shows the distribution of RNA-seq RPKM values (log2) for 11,376 P. gigantea genes when grown on basal salts containing acetone-extracted loblolly pine wood (ELP) or non-extracted loblolly pine wood (NELP). Lines define 2-fold borders and best fit regression. Darkened points represent 44 transcripts accumulating>4-fold at p<0.01. Venn diagram (B) illustrates genes with RPKM signals>10 and upregulated>4-fold in NELP relative to ELP. Twenty-two genes showed significant transcript accumulation in NELP relative to ELP suggesting potential response to resin and pitch content. Under these stringent thresholds (p<0.01;>4-fold), only one gene, a MCO model Phlgi1_129839, showed significant transcript accumulation in ELP relative to NELP. Additional detail appears in Tables 1-3. Detailed methods and complete data are presented in Text S1 and Dataset S2.
