  abstract = {1-{A}mino cyclopropane-1-carboxylic acid deaminase ({A}cd{S}) is an enzyme that degrades the precursor of plant hormone ethylene. {A}cd{S} activity has been identified in many soil bacteria. {I}t has been proposed to play an important role in plant-growth promotion by rhizobacteria. {I}t would lower ethylene level via uncharacterized signaling pathways in the host plant. {T}o further investigate the role of {A}cd{S} and the involvement of ethylene signaling pathway in plant development responses to rhizobacteria, we used the model plant {A}rabidopsis thaliana. {W}e compared the changes in root architecture and root hair length induced by four rhizobacteria ({P}hyllobacterium brassicacearum {STM}196, {P}seudomonas putida {UW}4, {R}hizobium leguminosarum 6v. viciae 128{C}53{K}, {M}esorhizobium loti {MAFF}303099) and by their respective acd{S}-deficient mutants. {A}ll the mutant strains induced similar changes in lateral root development as their {WT} counterparts. {B}y contrast, root hairs of seedlings inoculated with the acd{S} mutant strains were significantly longer than those of the plants inoculated with the {WT} strains. {O}verall, our results would suggest that rhizobacterial {A}cd{S} activity affects local regulatory mechanisms in plant roots, and not lateral root development that is under systemic regulation involving shoot-root dialog.},
