“…The role of NO as a signaling molecule has been confirmed in many plant species. It participates in both developmental and growth processes (e.g., [35][36][37][38], as well as in reactions to biotic [39,40] and abiotic [41][42][43][44] stresses, including Cd stress [20][21][22][23]. Interestingly, an excellent review by Meng et al [45] clearly showed that there is no universal pattern of changes in NO content in plant tissues under Cd stress conditions.…”

Nitric oxide (NO) is a signaling molecule that participates in plant adaptation to adverse environmental factors. This study aimed to clarify the role of NO in the regulation of vacuolar H+-ATPase (V-ATPase) in the roots of cucumber seedlings grown under control and Cd stress conditions. In addition, the relationship between NO and salicylic acid (SA), as well as their interrelations with hydrogen sulfide (H2S) and hydrogen peroxide (H2O2), have been verified. The effect of NO on V-ATPase was studied by analyzing two enzyme activities, the expression level of selected VHA genes and the protein level of selected VHA subunits in plants treated with a NO donor (sodium nitroprusside, SNP) and NO biosynthesis inhibitors (tungstate, WO42− and N-nitro-L-arginine methyl ester, L-NAME). Our results indicate that NO functions as a positive regulator of V-ATPase and that this regulation depends on NO generated by nitrate reductase and NOS-like activity. It was found that the mechanism of NO action is not related to changes in the gene expression or protein level of the V-ATPase subunits. The results suggest that in cucumber roots, NO signaling interacts with the SA pathway and, to a lesser extent, with two other known V-ATPase regulators, H2O2 and H2S.

“…Many reports suggest that nitric oxide (NO) participates in Cd-induced stress signaling and may be involved in tolerance acquiring [20][21][22][23]. However, little is known about V-ATPase modulation by NO [9][10][11].…”
