Identification and overexpression of gibberellin 2‐oxidase (GA2ox) in switchgrass (Panicum virgatum L.) for improved plant architecture and reduced biomass recalcitrance

Summary Gibberellin 2‐oxidases (GA2oxs) are a group of 2‐oxoglutarate‐dependent dioxygenases that catalyse the deactivation of bioactive GA or its precursors through 2β‐hydroxylation reaction. In this study, putatively novel switchgrass C20 GA2ox genes were identified with the aim of genetically eng...
