Abstract
Twenty four diverse cultivars of soybean (Glycine max [L.] Merrill) and three lines of its annual wild progenitor Glycine soja Sieb and Zucc. were tested for their response to Agrobacterium strains harboring either the Ti (tumor-inducing) plasmid (pTi) from Agrobacterium tumefaciens or the Ri (root-inducing) plasmid (pRi) from Agrobacterium rhizogenes following uniform wounding and inoculation. Based upon gall weight at 8 weeks postinfection, three G. max cultivars (Biloxi, Jupiter, and Peking) and one G. soja line, Plant Introduction (PI) 398.693B, were judged highly susceptible to A. tumefaciens strain A348 (pTiA6), ten genotypes moderately susceptible, 11 weakly susceptible, and two nonsusceptible. Of 26 genotypes inoculated with strain R1000 (pRiA4b), only seven responded in a clearly susceptible fashion by forming small, fleshy roots at internodal infection sites. Cotyledons excised from 1- or 3-day old seedlings of Peking and Biloxi cultivars also formed galls when infected in vitro with agrobacteria carrying either the Ti or Ri plasmid. Tumor lines established from cotyledon and stem galls induced by A. tumefaciens A348 (pTiA6) exhibited the T-DNA borne traits of phytohormone-independent growth and octopine synthesis. Additionally, DNA isolated from cultured tumors hybridized with labeled T-DNA probe.
