Abstract

<abstract abstract-type="main"> <title>Summary</title> <p>Patterning of numerous features of plants depends on transduction of the auxin signal. Auxin signaling is mediated by several pathways, the best understood of which relies on the function of the <italic>MONOPTEROS</italic> (<italic>MP</italic>) gene. Seven <italic>mp</italic> mutant alleles have been described in the widely used Columbia background of Arabidopsis: two extensively characterized and five only partially characterized. One of these five <italic>mp</italic> alleles appears to be extinct and thus unavailable for analysis. We show that two of the four remaining, partially characterized <italic>mp</italic> alleles reported to be in the Columbia background are in fact not in this background. We extend characterization of the remaining two Columbia alleles of <italic>mp</italic>, and we identify and characterize four new alleles of <italic>mp</italic> in the Columbia background, among which the first low‐expression allele of <italic>mp</italic> and the strongest Columbia allele of <italic>mp</italic>. These genetic resources provide the research community with new experimental opportunities for insight into the function of <italic>MP</italic>‐dependent auxin signaling in plant development. genesis 00:1–9. © 2013 Wiley Periodicals, Inc.</p> </abstract>
