text: "Auxin is a major plant growth regulator, but current models on auxin perception
and signaling cannot explain the whole plethora of auxin effects, in particular
those associated with rapid responses. A possible candidate for a component of
additional auxin perception mechanisms is the AUXIN BINDING PROTEIN 1 (ABP1),
whose function in planta remains unclear.\r\nHere we combined expression analysis
with gain- and loss-of-function approaches to analyze the role of ABP1 in plant
development. ABP1 shows a broad expression largely overlapping with, but not regulated
by, transcriptional auxin response activity. Furthermore, ABP1 activity is not
essential for the transcriptional auxin signaling. Genetic in planta analysis
revealed that abp1 loss-of-function mutants show largely normal development with
minor defects in bolting. On the other hand, ABP1 gain-of-function alleles show
a broad range of growth and developmental defects, including root and hypocotyl
growth and bending, lateral root and leaf development, bolting, as well as response
to heat stress. At the cellular level, ABP1 gain-of-function leads to impaired
auxin effect on PIN polar distribution and affects BFA-sensitive PIN intracellular
aggregation.\r\nThe gain-of-function analysis suggests a broad, but still mechanistically
unclear involvement of ABP1 in plant development, possibly masked in abp1 loss-of-function
mutants by a functional redundancy."

text: The Auxin Binding Protein 1 (ABP1) is one of the most studied proteins in
plants. Since decades ago, it has been the prime receptor candidate for the plant
hormone auxin with a plethora of described functions in auxin signaling and development.
The developmental importance of ABP1 has recently been questioned by identification
of Arabidopsis thaliana abp1 knock-out alleles that show no obvious phenotypes
under normal growth conditions. In this study, we examined the contradiction between
the normal growth and development of the abp1 knock-outs and the strong morphological
defects observed in three different ethanol-inducible abp1 knock-down mutants
( abp1-AS, SS12K, SS12S). By analyzing segregating populations of abp1 knock-out
vs. abp1 knock-down crosses we show that the strong morphological defects that
were believed to be the result of conditional down-regulation of ABP1 can be reproduced
also in the absence of the functional ABP1 protein. This data suggests that the
phenotypes in abp1 knock-down lines are due to the off-target effects and asks
for further reflections on the biological function of ABP1 or alternative explanations
for the missing phenotypic defects in the abp1 loss-of-function alleles.

text: The Auxin Binding Protein1 (ABP1) has been identified based on its ability
to bind auxin with high affinity and studied for a long time as a prime candidate
for the extracellular auxin receptor responsible for mediating in particular the
fast non-transcriptional auxin responses. However, the contradiction between the
embryo-lethal phenotypes of the originally described Arabidopsis T-DNA insertional
knock-out alleles (abp1-1 and abp1-1s) and the wild type-like phenotypes of other
recently described loss-of-function alleles (abp1-c1 and abp1-TD1) questions the
biological importance of ABP1 and relevance of the previous genetic studies. Here
we show that there is no hidden copy of the ABP1 gene in the Arabidopsis genome
but the embryo-lethal phenotypes of abp1-1 and abp1-1s alleles are very similar
to the knock-out phenotypes of the neighboring gene, BELAYA SMERT (BSM). Furthermore,
the allelic complementation test between bsm and abp1 alleles shows that the embryo-lethality
in the abp1-1 and abp1-1s alleles is caused by the off-target disruption of the
BSM locus by the T-DNA insertions. This clarifies the controversy of different
phenotypes among published abp1 knock-out alleles and asks for reflections on
the developmental role of ABP1.
