Understanding the fundamental molecular mechanisms
involved in sugar signalling will provide opportunities for
improving general plant growth and biomass accumulation,
and growth of harvestable organs. Sugar signals regulate
developmental processes such as floral transition that are
crucially important for plant yield as well. The repressor of
flowering miRNA156 is regulated by sugars via T6P signalling,
and overexpression of miRNA156 in switchgrass results
in increased biomass
