Transcriptomic analysis reveals vacuolar Na + (K + )/H + antiporter gene contributing to growth, development, and defense in switchgrass ( Panicum virgatum L.)

Background Intracellular Na+ (K+)/H+ antiporters (NHXs) have pivotal functions in regulating plant growth, development, and resistance to a range of stresses. To gain insight into the molecular events underlying their actions in switchgrass (Panicum virgatum L.), we analyzed transcriptomic changes between PvNHX1-overexpression transgenic lines and wild-type (WT) plants using RNA sequencing (RNA-seq) technology.
