Integrated transcriptomic and metabolomic analyses elucidate the mechanism by which grafting impacts potassium utilization efficiency in tobacco.

ABSTRACT:

Background

Potassium plays a crucial role in determining the quality of flue-cured tobacco leaves. Our prior investigations have demonstrated that using potassium-efficient rootstocks through grafting offers a viable solution to the prevalent issue of low potassium levels in Chinese flue-cured tobacco leaves. Nevertheless, the specific molecular mechanisms responsible for the increase in potassium content following grafting in tobacco leaves have yet to be elucidated. This study revealing for the first time how grafting improves potassium utilization efficiency through combined transcriptome and metabolome analysis.

Results

This study selected Wufeng NO. 2, a potassium-efficient variety, and Yunyan 87, a main cultivar, as the research subjects to investigate the underlying r
