Mesophyll protoplasts of eggplant (cv Black Beauty) and of Solanum torvum (both 2n=2x=24) were fused using a modification of the Menczel and Wolfe PEG/DMSO procedure. Protoplasts post-fusion were plated at 1 × 10(5)/ml in modified KM medium, which inhibited division of S. torvum protoplasts. One
Nicotiana tabacum (+)N. rustica interspecific somatic hybrids were produced by fusion of leaf mesophyll protoplasts of transgenic methotrexate-resistantNicotiana tabacum L. with leaf mesophyll protoplasts of transgenic kanamycin-resistantN. rustica L. Somatic hybrids were selected on the basis of
A biochemical system was devised to identify aneuploids of Nicotiana tabacum. Leaf tissue from 6 nullihaploids, 4 nullisomics, and 10 monosomics was analyzed electrophoretically on slab acrylamide gels. The staining systems used were for peroxidase, esterase, superoxide dismutase, malate
Patterns of organelle inheritance were examined among fertile somatic hybrids between allotetraploid Nicotiana tabacum L. (2n=4x=48) and a diploid wild relative N. glutinosa L. (2n=2x=24). Seventy somatic hybrids resistant to methotrexate and kanamycin were recovered following fusion of leaf
