Whole-transcriptome analyses of Sorghum leaves identify key mRNAs and ncRNAs associated with GA₃-mediated alleviation of salt stress.

ABSTRACT: Sorghum has recently attracted much attention for its tolerance in high salt environment. However, the effect and regulatory mechanism of the gibberellic acid (GA₃)-mediated alleviation of salt stress in sorghum remains unclear. Herein, we reported that a GA₃ concentration of 50 mg/L is optimal for sorghum ("Jitian 3") development under salt stress. We conducted a whole-transcriptome analysis between GA₃-treated and control sorghum leaves under salt stress, and we identified 1002 differentially expressed (DE)-messenger RNAs (mRNAs), 81 DE-long non-coding RNAs (lncRNAs), 7 DE-circular RNAs (circRNAs), and 26 DE-microRNA (miRNAs) in sorghum following GA₃ treatment. We also identified a majority of DE-mRNAs and non-coding RNAs (ncRNAs) targets that
