METHODS: We applied linear regression analysis to investigate the association of 435 SNPs in 112 positional and biological candidate genes with ABI and related physiological and biochemical traits in 1046 non-Hispanic white, hypertensive participants from the Genetic Epidemiology Network of Arteriopathy study.

我们应用线性回归分析调查协会435的SNPs在112位置和生物候选基因与ABI的和相关的生理生化性状的1046年非西班牙裔白人，高血压与会者从遗传流行病学的网络动脉的研究。

Analyzing the relations among betulin content and growth status, geographical location and climatic factors, it was found that the effect of growth status on betulin content was not significant, and betulin content was not only affected by self-provenance and heredity background but also by geographical location and climatic factor.

进一步分析可得，同龄树种的生长状况对白桦酯醇的含量影响不显著；而白桦酯醇的含量不仅受自身种源及遗传背景的影响，同时也受到其所处地理位置和气候因素的影响，即属于基因与环境互作的表现性状。

The results showed that genetic differences of nut characteristics between Castanea mollissima Bl.

对坚果性状的研究表明各品种间存在较大的遗传差异，而且大多数品种在不同区域的表现是稳定的。

The biological polymorphism of Cercospora zeae-maydis was studied systematically in the levels of histology, protein and DNA. The major characters in polymorphism of pathogen were listed as follows:(1) The great differences were seen in shapes and sizes of conidiophores, the growth velocity of mycelium and pigment-productivity of colony among pathogen strains. In addition, an albino strain, a kind of mutant, was casually discovered during isolation of pathogen from diseased plants, which supported strongly our previous prediction that there should be some potential genetic variation in Cercospora zeae-maydis.

本研究在组织学、蛋白质和DNA水平上，系统研究了玉米灰斑病菌的生物学多态性，这种多态性主要表现在以下几个方面：①病菌形态学和培养性状多态性：菌株间存在分生孢子形态、菌丝生长速度、菌落产色素能力等方面的差异，该病菌在自然界存在另一种变异类型——白化菌株，说明灰斑病菌的确存在遗传变异的潜能。
