While Brachypodium distachyon (Brachypodium) is an emerging model for grasses, no expression atlas or gene coexpression network available. Such tools are of high importance to provide insights into the function genes. We present a detailed atlas, capturing in its major organs at different developmental stages. The data were integrated large-scale database ( www.gene2function.de), enabling identification duplicated pathways and conserved processes across 10 plant species, thus allowing genome-wide inference function. highlight platform through cell wall modules, show that lignin biosynthesis module angiosperms. identified functionally characterised putative ferulate 5-hydroxylase overexpression it Brachypodium, which resulted increase syringyl units reduced content mature stems, led improved saccharification stem biomass. Our provides powerful resource reveal related genes, may advance our understanding important biological grasses.
