Potassium (K<sup>+</sup>) is the most abundant cation in plants, and its uptake and transport are key to growth, development and responses to the environment. Here, we report that <i>Arabidopsis thaliana</i> K<sup>+</sup> uptake permease 5 (AtKUP5) contains an adenylate cyclase (AC) catalytic center embedded in its N-terminal cytosolic domain. The purified recombinant AC domain generates cAMP <i>in vitro</i>; and when expressed in <i>Escherichia coli</i>, increases cAMP levels <i>in vivo</i>. Bo ...[more]
