What is Transfer of exogenous auxin from the phloem to the polar auxin transport pathway in pea (Pisum sativum L.) about?

indol-3yl-acetic acid ([1-14C]IAA) was applied to the upper surface of a mature foliage leaf of garden pea (Pisum sativum L. cv. Alderman), 14C etttuxed basipetally but not acropetally from 30-mm-long internode segments excised 4 h after the application of [1-14C]IAA. This basipetal efttux was strongly inhibited by the inclusion of 3"10-6 mol-dm-3 N-l-naphthylphthalamic acid (NPA) in the efftux buffer. In contrast, when [14C]sucrose was applied to the leaf, the etttux of label from stem segments excised subsequently was neither polar nor sensitive to NPA. The [1-14C]IAA was initially exported from mature leaves in the phloem -transport was rapid and apolar; label was recovered from aphids feeding on the stem; and label was recovered in exudates collected from severed petioles in 20 mM ethylenediaminetetraacetic acid. No 14C was detected in aphids feeding on the stems of plants to which [1-14C]IAA had been applied apically, even though the internode on which they were feeding transported considerable quantities of label. Localised applications of NPA to the stem strongly inhibited the basipetal transport of apically applied [1-14C]IAA, but did not affect transport of [1-14C]IAA in t
