Decades of research have suggested that AUXIN BINDING PROTEIN 1 (ABP1) is an essential membrane-associated auxin receptor, but recent findings directly contradict this view. Here we show that embryonic lethality observed in abp1-1, which has been a cornerstone of ABP1 studies, is caused by the deletion of the neighbouring BELAYA SMERT (BSM) gene, not by disruption of ABP1. On the basis of our results, we conclude that ABP1 is not essential for Arabidopsis development.
