Description
  • Brassica carinata mesophyll and B. rapa hypocotyl protoplasts were used for fusing experiments using polyethylene glycol (PEG). Treatment with 30% PEG 6000 MW for 10 minutes was more effective, while combinations with 30% PEG 6000 MW/15 min, 30% PEG 4000 MW/15 min and 30% PEG 4000 MW for 10 minutes reduced viability of protoplasts and cell wall regeneration, cell division and production of microcolonies. Fusion frequency was about 25% with the treatment of 30% PEG 6000 MW/10 min. Cell colonies forming callus was observed after 14 days of cultivation on liquid B medium with addition of liquid C medium. Microcalli were subsequently transferred to solid E and F medium. Shoot regeneration from calli was induced via indirect organogenesis and somatic embryogenesis on MS hormon free medium. In total 58 calli were obtained from fusions between B. rapa 31/96 and B. carinata line 1; 14 calli produce shoots. According to the estimate and morfological diferencies was half shoots heterocaryonicals. This observat

  • Mezofylové a hypokotylové protoplasty B. carinata a B. rapa byly použity pro fúzní experimenty s využitím polyetylén glykolu (PEG). Použití 30% PEG 6000 MW 10 minut bylo efektivnější než kombinace 30% PEG 600 MW 15 minut, 30% PEG 4000 MW 15 minut a 30% PEG 4000 MW 10 minut, které snižovaly životnost protoplastů a zabraňovaly regeneraci buněčné stěny a buněčnému dělení mikrokolonií. Frekvence fúzí byla okolo 25% při použití 30% PEG 6000 MW 10 minut. Ze získaných regenerantů bylo okolo 40 % analyzovaných vzorků pouze B.carinata x B.carinata fúzantů, zbylých 60 % byli fúzanti mezi B. carinata a B. rapa. (cs)
