ABSTRACT
fat Nodulation (Nod) factors are lipo-chitooligosaccharides (LCOs) secreted by rhizobia to trigger the early steps of nodule organogenesis in leguminous plants. A method to synthesize LCOs in vitro was developed. Synthetic LCOs alleviated the requirement for auxin and cytokinin to sustain growth of cultured tobacco protoplasts. LCOs containing C(181) trans-fatty acyl substituents were more effective than those containing cis-fatty acids in promoting cell division as well as in activating an auxin-responsive promoter and the expression of a gene implicated in auxin action. These data indicate that LCOs redirect plant growth also in nonlegumes by activating developmental pathways also targeted by phytohormones.
