Abstract
Six accessions of Glycine canescens and four of G. clandestina were evaluated for their response to inoculation with Agrobacterium rhizogenes strain LBA 9402. The response was accession-dependent, with 9% to 70% of the seedlings producing roots following infection of the hypocotyl. Excised cotyledons were less responsive than hypocotyls. Roots exhibited plagiotropic and negatively geotropic growth in culture on hormone-free agar medium; those of G. canescens produced shoots on B5 based medium containing 10 mg dm−3 BAP and 0.05 mg dm−3 IBA. Cultured roots and regenerated shoots synthesized opines. DNA sequences homologous to those of pRi TL and TR-DNA were present in a clonally propagated regenerated plant of G. canescens.
