title: Embryonic lethality ofArabidopsis abp1-1is caused by deletion of the adjacentBSMgene.
abstract: 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 inabp1-1, which has been a cornerstone of ABP1 studies, is caused by the deletion of the neighbouringBELAYA SMERT(BSM) gene, not by disruption ofABP1.On the basis of our results, we conclude that ABP1 is not essential forArabidopsisdevelopment.
