Kanamycin resistant plants of Solarium melongena L. (eggplant) cv. Picentia were obtained following the cocultivation of leaf explants with Agrobacterium tumefaciens. A disarmed binary vector system containing the neomycin phosphotransferase (NPTII) gene as the selectable marker and chloramphenicol acetyltransferase (CAT) as a reporter gene was utilized. In vitro grown plants were used as sources of explants to produce transgenic plants on selective medium containing 100 mg/l kanamycin. The transformation and expression of the foreign genes was confirmed by DNA hybridizations, leaf disc assays, and by measuring NPTII and CAT enzyme activities. This technique is simple, rapid, efficient, and transgenic eggplants of this commercial cultivar have been transferred to soil where they have flowered and set seed.

Direct gene transfer proved to be an efficient transformation method for Vigna aconitifolia, a member of the legume family. Kanamycin resistant calli and plants were regenerated from heat shocked protoplasts treated with PEG and plasmid DNA containing the coding region for aminoglycoside phosphotransferase gene (NPT II). The plant cultivar used was an important factor in attaining higher transformation frequencies. Transformation was confirmed by Southern blot analysis using a non-radioactive detection system. Attempts to transform mesophyll and suspension cultured cells by this method were unsuccessful. Protoplasts electroporated with the plasmid pCAP212, which codes for chloramphenicol acetyltransferase, exhibited transient expression of this gene two days after treatment while electroporated cells did not show this enzyme activity. It is therefore assumed that the DNA uptake is prevented by the cell wall.
