Cyclic mononucleotides modulate potassium and calcium flux responses to H2O2 in Arabidopsis roots.

Highlights: [•] We show that H2O2 modulates potassium and calcium net fluxes in Arabidopsis roots. [•] We examine the effect of cyclic mononucleotide pre-treatment on these fluxes. [•] We also investigate the effect of cGMP on the microsomal proteome. [•] cGMP is sufficient to induce complex cellular changes to responses induced by H2O2. [Copyright &y& Elsevier]
