text: Background:Auxin binding protein 1 (ABP1) is a putative auxin receptor and
its function is indispensable for plant growth and development. ABP1 has been
shown to be involved in auxin-dependent regulation of cell division and expansion,
in plasma-membrane-related processes such as changes in transmembrane potential,
and in the regulation of clathrin-dependent endocytosis. However, the ABP1-regulated
downstream pathway remains elusive.Methodology/Principal Findings:Using auxin
transport assays and quantitative analysis of cellular morphology we show that
ABP1 regulates auxin efflux from tobacco BY-2 cells. The overexpression of ABP1can
counterbalance increased auxin efflux and auxin starvation phenotypes caused by
the overexpression of PIN auxin efflux carrier. Relevant mechanism involves the
ABP1-controlled vesicle trafficking processes, including positive regulation of
endocytosis of PIN auxin efflux carriers, as indicated by fluorescence recovery
after photobleaching (FRAP) and pharmacological manipulations.Conclusions/Significance:The
findings indicate the involvement of ABP1 in control of rate of auxin transport
across plasma membrane emphasizing the role of ABP1 in regulation of PIN activity
at the plasma membrane, and highlighting the relevance of ABP1 for the formation
of developmentally important, PIN-dependent auxin gradients.
