Differential expression of starch and sucrose metabolic genes linked to varying biomass yield in Miscanthus hybrids.

ABSTRACT:

Background

Miscanthus is a commercial lignocellulosic biomass crop owing to its high biomass productivity and low chemical input requirements. Within an interspecific Miscanthus cross, progeny with high biomass yield were shown to have low concentrations of starch and sucrose but high concentrations of fructose. We performed a transcriptional RNA-seq analysis between selected Miscanthus hybrids with contrasting values for these phenotypes to clarify how these phenotypes are genetically controlled.

Results

We observed that genes directly involved in the synthesis and degradation of starch and sucrose were down-regulated in high-yielding Miscanthus hybrids. At the same time, glycolysis and export of triose phosphates were up-regulated in high-yielding Miscanthus hybrids. These
