Panicum virgatum | overexpression of two gibberellin 2beta-dioxygenase genes, that is PvGA2ox5 and PvGA2ox9, results in characteristic gibberellin-deficient phenotypes with dark-green leaves and modified plant architecture. The changes in plant morphology appear to be associated with GA2ox transcript abundance. Exogenous application of GA rescues the GA-deficient phenotypes in transgenic lines. Transgenic semi-dwarf lines display increased tillering and reduced lignin content, and the syringyl/guaiacyl lignin monomer ratio accompanied by the reduced expression of lignin biosynthetic genes compared to nontransgenic plants. A moderate increase in the level of glucose release in these transgenic lines might be attributed to reduced biomass recalcitrance as a result of reduced lignin content and lignin composition.
