Polar auxin transport

To determine whether the reduced polar auxin transport observed in IFS knockdown plants was causal to the absence of nodulation, the authors conducted...

The inhibition of growth by ethylene in subhook regions of etiolated pea seedlings is largely due to reduction in the polar auxin transport system which supplies auxin to the cells (42,... 

A new class of plant auxin herbicides are the phytotropins, exemplified by the semicarbazone diflufenzopyr [148], Diflufenzopyr is a systemic herbicide for the selective control of broadleaf and perennial weeds in corn. Unlike the early auxin herbicides, such as 2,4-d and dicamba, which acted as mimics of indole-3-acetic acid, phytotropins prevent polar auxin transport in sensitive plants, causing stunting and loss of tropic response [149],... 

Long-distance lAA transport from the apex downwards occurs at least partly in the phloem. Short-distance transport occurs by a process called polar auxin transport [45]. This involves a symmetrical uptake of lAA into cells up a pH gradient, coupled with unidirectional efflux of lAA from the basal end of cells. Auxin is removed from the...

Fig. 4. Effects of quercetin on polar auxin transport by zucchini hypocotyl segments. Data are counts per min collected in the pooled receivers of quintuplicate samples over the half-hour periods shown and for the period from 2 to 3 h of transport. Open panels control treatment, shaded panels quercetin...

Wangermann and Withers (1978) have recently put forward the interesting hypothesis that polar auxin transport is linked to the presence of plasmalemma-somes (Fig. 3.7). These structures were shown to be present in parenchyma cells in sections known to exhibit a functional auxin transport system but were absent in the absence of transport. The authors speculated that transport channels might be initiated by the production of plasmalemmasomes in the cells.
