收获和确幸:
1)文献思路就是:天然产物的特性及具有修饰---已知基因作为诱饵调取未知基因,位置基因调取共表达基因,两方互相验证---基因烟草表达验证检测---检测出的基因调取烟草表达验证---类似的修饰相关基因homology gene验证
2)文献实验方法以及写作方面可以参考
摘要:背景三萜类具有复杂的支架结构,limonoids柠檬苦素具有多种商业价值典型家族。问题:尽管商业价值高,但是完整通路为解析。结果:发现22个酶,包括一对新功能化的固醇异构酶,它们催化了kihadalactone a和azadirone的12种不同的生物合成反应,这些产物具有标志性的柠檬醛呋喃。
结果:1)柑橘属的limonoid合成通路的候选基因鉴定:以已知的CSOSC1基因作为baitgene,调出一些候选基因,candidate gene as bait gene调取候选基因验证候选基因;楝树缺少参考基因组和高质量转录组,组装后以已知的MaCYP71CD2 MaCYP71和MaOSC1为bait gene调取了17个candidate gene
结果2): CYP88A51 and CYP88A108在不同的meliano oxide isomerases作用下产生不同支架;鉴定出MOI新功能酶
结果3:筛选甲基转移酶时发现酰基转移酶和脱氢还原酶:
