Rhizogenestransformed roots of three forage legumes (Trifolium pratense, Macroptilium atropurpureum, and Medicago sativa) were inoculated with Rhizobium. It was suggested by the authors that the inhibition of nodulation was linked to the expression of Ri T-DNA genes rather than to persisting Agrobacteria in the plant tissues. No major difference was observed in size and shape between nodules developed on transformed and untransformed roots. Acetylene-reduction activity exhibited by transformed and untransformed 4-week-old nodules was comparable (45)lmol C2 HJg dry weight/nodule/h).

Tumefaciens were optimized on Casuarina gLauca (Le et at. 1996). The influence of the following parameters was studied: the selection marker and its concentration (kanamycin or hygrornycin from 5 to 200mgtl). the strain of A. tumefaciens (C58C1(GV2260; pBIN19GUSINT), LBA 4404(pAlM04; pBIN19GUSINT), and LBA4404(pAL4404; pT0K233)), the explant (hypocotyls, cotyledons, or epicotyls), the addition of acetosyringone (0 to lOOIlM) during cocultivation. the duration of cocultivation (one to 7 days), the age of the explants, the pH of cocultivation (5 to 6), and a pretreatment of the explants by naked microprojectiles.
