“Here, we report that NO lowers K+ channel AKT1-mediated plant K+ uptake by modulating vitamin B6 biosynthesis.”
“These findings reveal a previously unidentified pivotal role of NO in modulating the homeostasis of vitamin B6 and potassium nutrition in plants, and shed light on the mechanism of NO in plant acclimation to environmental changes.”
“Together, our results suggest that NO decreases K+ absorption by promoting the synthesis of vitamin B6 PLP, which further represses the activity of K+ channel AKT1 in Arabidopsis.”
“We showed that NO increased PLP and decreased K+ levels in plant.”
