  • Leaf mesophyll protoplasts of Nicotiana tabacum (nitrate reductase deficient mutant) were fused with cell suspension protoplasts of albino Petunia inflata in an electric field. Hybrid cell colonies were selected for nitrate reductase proficiency and chlorophyll synthesis. Five hybrid plant lines, regenerated from the selected calli lines, were analysed by electrophoresis, number of chromosomes and morphological characters. Somtic hybrid plants showed both parent patterns in the isozymesof isoleucine aminopeptidase and esterase. The hybrids had the expected chromosome number of 62 and exhibited an intermediate floral morphology when compared with the parents, but plant height and leaf arrangement were similar to N. tabacum.

  • Hibiscus cannabinus, Cassia fistula and Abutilon indicum are medicinally important plants in India. Tissue culture studies have done for efficient propagation and for crop improvement in these three plants. Various explants were tried for callus induction, somatic embryogenesis and organagenesis with manipulation in culture media. Calli and somatic embryos were induced from hypocotyl explants in Hibiscus cannabinus, while in Cassia fistula and Abutilon indicum it could be obtained from leaf explants.

  • Protoplasts of palisade cells were aseptically isolated from leaves of Nicotiono apicona Merxm. by the one step enzymatic method. Efficiency of colony formation were depended on cell density and light condition during incubation, but an intensity of 47 ft-c during a period of 2 weeks after isolation of the protoplasts in the Nagata and Takebe's medium promoted the planting efficiency. Protoplast - derived calli of N. africana can be differentiated into shoot when cultured on Murashige and skoog's medium containing IAA(0.Smg/$\ell$) and zeatin(5.0mg/$\ell$).

  • Protopasts were isolated from cultured cells of potato (Solanum tuberosum L.) tuber tissue. The ability of callus formation from the culture cells was higher in cultivars Dejima and Superior than in Shimabara and Irish Cobbler on Lam's medium. Therefore, the former was used as sources for protoplast isolation. Friable calli were transferred to liquid media and cells in exponential phase were used for protoplast isolation. In both of Dejima and Superior, the yield of protoplasts was high in the enzyme solution of 2% Onozuka cellulase and 1% macerozyme. Also, viability of isolated protoplasts was very good. Thus, it seems that these protoplasts would be applicable to various aims of research.

  • The regenerative capacities of protoplasts isolated from potato (Solamum tuberosum L.) tubers and tobacco (Nicotiana tabacum L.) mesophyll tissues were examined, and then their intergeneric protoplast fusion was carried out. The potato tuber-derived protoplasts proliferated into the calli some of which showed rudimentary shoot-like structures, which had not been attempted before from tubers, while the tobacco protoplasts were regenerated into the whole plants. Intergeneric protoplast fusion between potato and tobacco was carried out and the heteroplasmic fusion products were formed. The first cell division of some of them was observed after 5 days of culture.
