建立了一套提高芜菁小孢子胚胎发生和植株再生效率的方法。用生长素拮抗剂对氯苯氧异丁酸(PCIB)促进小孢子胚胎发生和植株再生。4种基因型对PCIB均呈阳性反应。在NLN-13培养基中,PCIB的最适浓度为40μM,与对照相比,其胚数增加了3.4 ~ 6.2倍(8.27-19.2个胚/芽),植株再生频率增加了9.6倍(21.33%)。通过在35°C下孵育1天的热休克处理在2个测试基因型中诱导胚胎发生更有效。在附加40μM PCIB的NLN培养基中,胚在21日龄时转移,然后在4 ℃下处理5 d,直接植株再生率最高,达58.00%。
An efficient protocol to improve microspore embryogenesis and plant regeneration in Brassica rapa was established. The antiauxin p-chlorophenoxyisobutyric acid (PCIB) was used to enhance microspore embryogenesis and plant regeneration without an intervening callus phase. All the 4 tested genotypes responded positively to PCIB. The optimum concentration of PCIB application was found to be 40μM in NLN-13 medium, which resulted in a 3.4- to 6.2-fold increase in the number of embryos (8.27–19.2 embryos per bud) and a 9.6-fold increase (21.33%) in the plant regeneration frequency in comparison with the controls. Heat-shock treatment by incubation at 35°C for 1 day was more efficient in inducing embryogenesis in the 2 tested genotypes. The embryos, produced in NLN medium supplemented with 40μM PCIB and transferred at the 21-day-old followed by a treatment at 4°C for 5 days, reached the highest direct plant regeneration rate of 58.00%.
