Auxin Production by Species of Arthrobacter

Nature volume 191, pages 1323–1324 (1961)Cite this article

Abstract

THE ability of fungi and bacteria to produce plant growth-promoting substances such as indole-3-acetic acid (IAA) has long been recognized1–3. Gruen3 has recently reviewed the literature on auxin production by fungi. However, reports on bacterial synthesis are widely dispersed, and relatively few known species have been recorded as being able to produce these substances, although many unidentified cultures have been tested1. Of the known organisms, Escherichia coli, Pseudomonas fluorescens, Agrobacterium tumefaciens, Rhizobium sp. and Azotobacter sp. have received most attention4–6, yet one of the largest groups of soil bacteria, the Arthrobacter, has not, to our knowledge, been examined.
