The vacuole pH-related gene RcNHX2 affects flower color shift and Na+ homeostasis in roses

Below I attached an article preview on an exciting issue:

Conclusions

In this study, a vacuolar membrane-localized Na+/H+ transporter protein (RcNHX2) was identified, which demonstrated significant overexpression in blue rose petals. This overexpression of RcNHX2 was found to increase the pH value of petal vesicles and induce a shift in the flower color towards blue. Furthermore, RcNHX2 exhibited ion transport activity and responsiveness to Na+, thereby playing a crucial role in regulating homeostasis. The functions of the vesicular Na+/H+ transporter gene RcNHX2
