RNA-Seq analysis of PKS8-1 cluster genes.

PKS8-1 and adjacent genes in the P. fijiensis genome are represented by arrows indicating their direction, with descriptions of putative protein functions indicated below the arrows. Blue arrows = genes predicted by Noar and Daub [18] to be part of the PKS8-1 gene cluster; Gray arrows = genes predicted by Noar and Daub [18] to flank the PKS8-1 gene cluster. Scale bar indicates 5 kb. Black bars are proportional to log2FC values of expression in leaf tissue vs. culture medium. Single asterisks represent significant expression differences at p<0.05, and double asterisks represent significant expression differences at p<0.01. NE = no expression detected.
