煙草和煙草製品化學分析方法.第17部分:煙堿純度測定It is shown that regression models are fewer latent variables and more stable by using osc method. the number of latent variables of nicotine model is reduced from 7 to 3 ; and the number of latent variables total - sugar is reduced from 6 to 3. at the same time, we also found that osc is more excellent when it is applied on complex powder system than simple system
結果表明在保證模型預測能力的同時， osc校正法極強的濾波能力降低模型的復雜度，也即煙草煙堿模型主因子數從7減少為3 ，煙草總糖模型主因子數從6減少為3 ，四元混合體系液體樣品中甲苯預測模型主因子數從4減少為3 。( 3 ) on the basis of the deletion analysis, three substitution mutants ( ml : 6bp sequence upstream of gcc box m2 : gcc box and m3 : g box - like sequence ) by pcr were designed to isolate the essential ja - responsive element. transgenic tobacco plants containing promoter substitution constructs were generated by agrobacterium - rnqdiaied leaf transformation. loss - of - function experiment, using transient expression analysis of gus reporter genes, confirmed that gcc box act as an essential element to respond ja signaling in pdf1. 2 promoter
（ 3 ）在缺失突變的基礎上，通過對gccbox及其相鄰的上下游六個堿基進行取代突變，將突變啟動子與gus構建融合基因，在煙草中受heja誘導的瞬時表達結果表明， h1和m3的突變對該啟動子應答ja信號的影響很小，而m2 （ gccbox的突變）則幾乎使該啟動子應答ja信號的功能完全喪失，所以gccbox是該啟動子中應答ja信號的必需元件。Environmental tobacco smoke - determination of vapour phase nicotine and 3 - ethenylpyridine in air - gas - chromatographic method
