  abstract = {l{A}rmadillo/beta-catenin and related proteins have important functions during animal and {D}ictyostelium development, regulating cell differentiation, proliferation, and adhesion. {A}rmadillo-repeat-containing proteins also exist in plants, but the majority have unknown roles. {T}he {A}rabidopsis genes that show greatest sequence homology to {A}rmadillo/beta-catenin are called {ARABIDILLO}-1 and -2. {H}ere, we demonstrate that {ARABIDILLO}-1 and -2 promote lateral root development. arabidillo-1/-2 mutants form fewer lateral roots, and {ARABIDILLO}-1-overexpressing lines produce more lateral roots than wild-type seedlings. {ARABIDILLO}-yellow fluorescent protein fusions are nuclear. {ARABIDILLO} proteins contain an {F}-box motif, and thus may target other proteins for proteasomal degradation. {O}verexpression of {ARABIDILLO}-1 protein fragments, including {F}-box fragments, in wild-type seedlings reduces lateral root formation to the level of the arabidillo-1/-2 mutant. {W}e have shown that plant beta-catenin-related proteins regulate root development. {W}e suggest that {ARABIDILLO} proteins may target an inhibitor of lateral root development for degradation and propose that {A}rabidopsis 13-catenin-related proteins define a previously uncharacterized pathway that promotes root branching.},
