  1. Expression values are shown as log2 values. A -1 value in the (Populus 12 hours) - (Populus 37 hours) column would indicate that this gene had 2-fold higher expression in the C. thermocellum Populus 37-hour fermentation compared to the C. thermocellum Populus 12-hour sample; a positive value would indicate greater expression from the Populus 12-hour sample. Bold face values indicate values were significant for this comparison. FDR, false discovery rate; KDMM, kernel density mean of M component; RNA-seq, RNA sequencing.
