  High-efficiency regnerationin vitro from potato petioles with intact leaflets

  摘要：

  The shoot/plantlet regeneration in vitro of seven potato (Solanum tuberosum L.) cultivars from petioles with intact leaflets was assessed using six treatment combinations - a basal medium with or without silver thiosulphate (STS) or thidiazuron (TDZ) at two concentrations (2 or 0.5 mg/l) of the indoleacetic acid (IAA). The basal medium consisted of Murashige and Skoog (IMS) salts and vitamins supplemented with 3 mg/l 6-benzylaminopurine, and 1 mg/l gibberellic acid, 30 g/l sucrose, and 7.0 g/l PHY-TOAGAR. TWO full sets repeats and one partial set repeat of independent experiments were conducted and all produced similar results. Silver thiosulphate decreased the regeneration frequency and number of shoots peer callus. No significant changes were observed with thidiazuron. Regeneration rates of (100%) with up to 20 shoots/plantlets per callus were achieved at 2 mg/l IAA with cultivars Desiree, Kennebec, Niska, and Lenape. These cultivars still showed high regeneration rates (87%-98%) on media with 0.5 mg/l IAA, and good regeneration rates were also achieved by the other three cultivars (48%, 94%, and 50% for Chieftain, Russet Burbank, and Shepody, respectively). Even with the single medium protocol (0.5% IAA without thiosulphate or thidiazuron), Desiree, Lenape, and Niska exhibited a regeneration rate of 98%. The use of petiole-with-leaflet explants could be ideal for the regeneration step of potato genetic transformation protocol because of their high regeneration efficiency and their small cut surface area for Agrobacterium elimination after co-incubation.
