Involvement of polyamines in the inhibiting effect of injury caused by cutting on K super(+) uptake through the plasma membrane

The inhibition of K super(+) uptake through the plasma membrane resulting from injury caused by cutting, or from application of polyamines (PAs), has been investigated in root segments of maize (Zea mays) L.) and pea (Pisum sativum L.). The data seem to indicate that PAs and their degradation produc...

Description
Summary:The inhibition of K super(+) uptake through the plasma membrane resulting from injury caused by cutting, or from application of polyamines (PAs), has been investigated in root segments of maize (Zea mays) L.) and pea (Pisum sativum L.). The data seem to indicate that PAs and their degradation products are responsible for the inhibition of K super(+) uptake occurring as a result of injury sustained by cutting roots into segments.
