摘要:
通过CRISPR/Cas9基因编辑技术,在水稻品种日本晴中获得了OsPCK1基因缺失的基因编辑突变体ospck1。对比了突变体与野生型水稻种子在萌发过程中的差异,并进一步探究OsPCK1在该过程中可能的作用。结果表明,OsPCK1缺失后,突变体种子具有更快的萌发速度、更优异的长势和更强的活力。进一步测定了总可溶性蛋白、游离氨基酸及糖组分的含量,并检测了OsGA20ox、OsGA3ox和OsABA8OH家族基因的表达量以及水稻内源赤霉素(GA)与脱落酸(ABA)含量。研究发现,突变体与野生型种子在萌发过程中的差异较为显著,突变体中通过促进种子贮藏物质水解为可溶性蛋白与游离氨基酸,从而加强种子萌发初期的吸水能力与代谢活力,并通过调控ABA/GA的平衡,使得突变体种子相较于野生型更容易在适宜的生长条件下萌发。这些结果为揭示OsPCK1基因在水稻中的作用机制提供了参考依据。
