摘要:
为系统探究藜麦三萜皂苷的生物合成关键调控基因及代谢通路,解析其分子调控机制,为藜麦皂苷代谢调控研究及低皂苷品种的选育提供理论依据,通过测定30份藜麦品系的总皂苷含量,筛选出总皂苷含量差异显著的QB9和QB10品系,进行转录组测序技术分析。2个品系间共鉴定到2 304个差异表达基因,其中789个基因显著上调,1 515个基因显著下调。KEGG富集结果中存在4条与三萜皂苷生物合成相关的代谢通路,其中萜类骨架生物合成途径、倍半萜和三萜生物合成途径是藜麦三萜皂苷形成的关键合成通路。4条合成通路共富集到与藜麦皂苷生物合成相关基因22个。在藜麦皂苷生物合成途径中的前体物质合成阶段,基因LOC110692772、LOC110732629、LOC110713460在此阶段发挥关键作用。在三萜骨架形成阶段,基因LOC110705162、LOC110705167、LOC110707032参与其中。在皂苷元修饰阶段,LOC110714192、LOC110725244赋予三萜骨架功能多样性。这些发现为深入解析藜麦皂苷生物合成的分子机制提供了重要线索。
