小麦过氧化物酶特异表达模式与生化性质研究

SPECIFIC EXPRESSION PATTERNS AND BIOCHEMICAL QUALITY RESEARCH OF PEROXIDASE IN COMMON WHEAT

通过大量不同类型品种的普通小麦、杂交品系F1代等，对过氧化物酶的特异表达与遗传转换模式及转录间的关系进行了研究。实验表明不同材料中总共有1－4种mRNA转录本，其分子核苷酸分别为0．6kb、2．1kb、3．8kb和4．9kb。研究显示影响Px基因表达信号的差异主要是转录本数量、不同mRNA转录本决定Px基因表达过程中的转录水平。有关生化性质研究也显示了其AA组成、含量特征的生化特性关系。

The research go a step furture studied about the specific expression patterns,genetic coversion laws and relation biochemical quality of the peroxidases,used lots kind ofthe varieties,hybridized breed systeam F1 generation.Research show that different material have 1-4 kinds of mRNA transcript,its molecular nucleotide for 0.6 kb, 2. 1 kb, 3.8 kb and 4. 9 kb. The variance of Px gene expression signal was inpact by the amount oftranscripts. The level of transeripts in Px gene expression course was decided by mRNAtranscript distict.
