title: [Effect of indolylacetic acid on formation of bacteroid forms of Rhizobium leguminosarum].
abstract: The purpose of this work was to study the effect of indolylacetic acid (IAA) on the strains of Rhizobium leguminosarum, effective and noneffective with respect to symbiotic nitrogen fixation (L4 and 245a, and 14--73, respectively). IAA at a concentration of 50 mcg/ml and higher inhibited the growth of the bacterium, temporarily delayed celular division, and induced intensive formation of elongated bacteroid-like cells, predominantly Y-shaped or having a clavate shape. Many bacteroid-like cells were capable of division after a certain delay.
