Is grape berry ripening delay induced by a pre-véraison NAA treatment paralleled by a shift in the expression pattern of auxin- and ethylene-related genes?
This study suggests that, in presence of altered levels of auxins, the crosstalk between hormones involves diverse mechanisms, acting at both the hormone response and biosynthesis levels, creating a complex response network.
Our results indicate that the PDE3-inhibitory property of levosimendan was enough to account for its inotropic effect, leaving a minor, if any, effect to a calcium-sensitizing component.
