The diversity of opines from 43 naturally occurring crown gall tumors on several plant species was analyzed for the presence of agropine, chrysopine, iminodiacid, an unidentified leucinopine-like iminodiacid (IDA-B), mannopine, octopine, nopaline, DL

The mocC gene encoded by the octopine/mannityl opine-type Ti plasmid pTi15955 is related at the nucleotide sequence level to mas1' encoded by the T region of this plasmid. While Mas1 is required for the synthesis of mannopine (MOP) by crown gall tumo

Three phytotoxins, ascochytine [1], pyrenolide A [2], and a new metabolite hyalopyrone [3], were isolated from cultures of Ascochyta hyalospora, the causal agent of lambsquarters leaf spot. All three toxins were phytotoxic on nine weed species. Ascoc

We have examined the uptake of [14C]octopine and [14C]nopaline by Agrobacterium tumefaciens strains containing the C58 chromosomal background in medium suitable for the induction of vir genes. All strains tested could transport both of these opines,
