Resumen:
In this study, we have investigated the regulation of adventitious
root (AR) formation by extracellular ATP (eATP) in cucumber
(Cucumis sativus) explants. Cutting seedlings responded in a dosedependent
manner to eATP as evidenced by a higher number and
length of ARs compared with controls. The eATP-induced AR
formation was mimicked by a very low dose (20.0 pM) of the nonhydrolysable
ATP analogue, S-ãATP. Adenosine, as other signal
molecule, modulated S-ãATP-mediated AR formation at
concentrations that did not produce a significant response when
applied separately to the cutting seedlings
