Scientists hope to harness fungi that decompose the most abundant type of biomass in wood, lignocellulose. Lignocellulose could be used to create the building-blocks of polymers for bioproducts. The key to understanding how fungal enzymes break down wood is to examine gene expression patterns. These patterns are typically measured in comparison to so-called ‘housekeeping genes.’ Housekeeping genes are expressed at reliable, steady levels. But conventional housekeeping genes in other fungi are not steadily expressed in wood-decomposing fungi. In a recent study, scientists found better, more steadily expressed housekeeping genes to reliably measure gene expression across the entire genome of these important fungi.
