摘要:
羽衣甘蓝是2年生植物,2年完成1个有性生殖世代,游离小孢子培养是加快其纯合化的有效途径。但是由于羽衣甘蓝小孢子培养的诱胚率低,使其难以育种应用。组蛋白乙酰化是一种重要的表观遗传学机制,影响小孢子发育途径,促进小孢子胚状体发生。本研究分别用不同浓度的组蛋白去乙酰化抑制剂辛二酰苯胺异羟肟酸和曲古菌素A处理羽衣甘蓝红斑鸠的小孢子,以诱导胚状体发生。结果表明,辛二酰苯胺异羟肟酸浓度为0.075 μmol/L时,红斑鸠获得最多胚状体,为每个花蕾获得20.24个胚状体,同时直接成苗率也达到最高,为16.07%。曲古菌素A浓度为0~0.150 μmol/L时,红斑鸠的胚状体发生率和直接成苗率都降低。适当浓度的辛二酰苯胺异羟肟酸可以促进羽衣甘蓝红斑鸠小孢子胚状体发生和直接成苗率,而0~0.150 μmol/L曲古菌素A对羽衣甘蓝红斑鸠胚状体的发生和直接成苗率有抑制作用。
