1H NMR spectroscopic analysis of aromatic protons combined with theoretical analysis of molecular structures proved the existence of two rotational isomers at 300 K, as well as a rapid interconversion equilibrium at 330 K for both compounds Ⅰ and Ⅱ. However, only one conformer exists for compound Ⅲ and puerarin containing 7-phenolic hydroxyl instead of propyl in A-ring as the case of compounds Ⅰ and Ⅱ. Based on UV-Visible absorption data of neutral and basic solutions, and on the density function calculations, the 7-phenolic hydroxyl group in A-ring was found to be more acidic than the 4'-phenolic hydroxyl group in B-ring. The mechanism of derivation reaction and the structure-reactivity relationship of puerarin as an antioxidant were further discussed.

其中7-丙基葛根素Ⅱ属于新型取代衍生物；变温1H NMR和理论计算结果表明，在300 K时，葛根素和4'-丙基葛根素以单一构型存在；而7，4'-二丙基葛根素和7-丙基葛根素则存在两种核磁可分辨的旋转异构体，当温度升至330 K时，两种异构体可以相互转化；通过对比分析葛根素及其衍生物脱质子产物的紫外可见吸收光谱并结合理论计算，确定了A环上7位酚羟基比B环上4'位酚羟基先脱去质子，并由此进一步阐明了葛根素衍生化反应机理以及在抗氧化作用中可能的活性位点和结构活性关系。

But mutants showed no differences in growth, appressorium turgor, and virulence capacity to barley and rice CO39. 7. GFP controlled by mtp1 promotor was expressed mainly in hyphae and spores, less expressed in appressoria. mtp1 has no visible effects on the growth of rive blast fungus. However, it has significant effects on conidiation, conidium germination of the fungus.

mtp1启动子指导的GFP蛋白主要在稻瘟病菌的菌丝和孢子中表达，附着胞中表达量较少。mtp1基因对于稻瘟病菌的生长没有明显的作用，但对于稻瘟病菌的产孢、孢子萌发具有重要的作用。
