abstract：:In the coenobia-forming green alga, Hydrodictyon reticulatum, changes in DNA composition during growth and differentiation of reproductive cells were followed. A "loss" of DNA per nucleus could be attributed to underreplication of an amplified DNA fraction being part of a (GC)-rich satellite band in CsCl gradients of ...

abstract：:Methods of shoot and plant development from cotyledon explants of the tomato cultivar 'Bonner Beste' and its mutant chloronerva are described. Cotyledon mesophyll protoplasts of the mutant chloronerva have been isolated and cultured, and induced to regenerate shoots and plants. By grafting regenerated shoots of the ch...

abstract：:Medicago sativa lines with a high incidence of regeneration were established as suspension cultures and used to select for NaCl tolerant lines. Attempts were then made to regenerate plants from these lines. Regeneration was severely depressed in NaCl tolerant calli and the only plants that were successfully regenerate...

abstract：:The interconversion between 5 to 8-membered cycloalkanones and the corresponding cycloalkanols by a cell suspension culture of Nicotiana tabacum was studied. It was found that the interconversion is at equilibrium and the balance in the equilibrium depends on the number of carbon atoms in the carbocyclic ring of the s...

abstract：:Protoplasts isolated enzymatically from seedling roots, hypocotyls and cotyledons of Lotus corniculatus L. produced callus which underwent prolific shoot regeneration. The rapidity and ease of recovering plants from protoplast-derived tissues makes this forage legume an attractive experimental system for genetic manip...

abstract：:The influence of light on the expression of NADPH: protochlorophyllide oxidoreductase has been studied in different plant species. The presumptive precursors to this enzyme have been characterized by in vitro translation of poly (A) RNA and immunoprecipitation. Two bands of apparent molecular weights of about 42 000 a...

abstract：:Rapid clonal propagation in three stolon bearing species of Nephrolepis was achieved by tissue culture methods. Explants from young stolons were grown on B5 (Gamborg et al. 1968) medium supplemented with indolebutyric acid where they produced several leaf primordia. These leaf primordia were isolated and grown into en...

abstract：:Somatic embryos and plantlets have been obtained in quite a direct way from mesophyll protoplasts isolated from androgenetic plants of two cultivars ("Loras" and "Tower") of Brassica napus. The procedure consists of four steps. Proembryos were induced in a medium supplemented with a cytokinin and an auxin at comparati...
