以圆果化香植株的芽为基本构件单元，对贵州中部喀斯特山地不同坡位上8-12年生植株的芽种群结构进行研究，结果表明：圆果化香芽种群芽总量分配随枝级发生变化，芽数量最多的枝级为树冠中间部位的二级或三级枝，树冠表层的末生枝和紧靠树干的一级枝芽数量较少。

An all previous dynasties book on Chinese medicine important toxicity to the human body harm degree has divided into greatly poisonously it virulent the small poisonous three levels or adds the micro poisonous level.

然而，中药并非无毒，其毒性的产生与炮制，配伍，用量等有关。中药毒性学领域至今无统一的毒性分级定量标准。历代本草一重要毒性对人体损害程度，将其分为了大毒、有毒、小毒三级，或加微毒一级。

GA3 contents, POD activities and invertase activities started to increase significantly while IAA contents started to decrease significantly when plants entered the critical stage of flower-bud differentiation; GA3 contents, POD activities and invertase activities emerged high apex value while IAA contents emerged low apex value when plants entered stage of primar...

当植株进入花芽分化临界期时，叶片中GA3含量以及POD和转化酶活性均开始剧增，而IAA含量开始剧减；当植株进入第1侧花茎原基分化期和第2～3侧花茎原基分化期，叶片中GA3含量和POD、转化酶活性均出现一高峰值，而IAA含量出现一低峰值。可见，青花菜侧花茎每一级的花芽分化要求较高含量的GA3、较低含量的IAA和较高活性的POD、转化酶。

In this study, the genomic structure and regulatory elements of ApoD from 10 representive species including protozoan, invertebrate, protochordate and vertebrate were analyzed and compared. The genomic structure of ApoD is less conserved in organisms from protostome to deuterostome invertebrates, while it is highly conserved among chordates including amphioxus and verebrates. All four conserved cysteine residues are present in amino acid sequence of deuterostome ApoDs, while there are only two cysteine residues in amino acid sequence of protostomes ApoD. Structure divergence between protostome and deuterostome ApoD proteins suggests their function difference. The majority of regulatory elements are present in nearly all organism ApoD genes ranging from unicellular protozoan to mammals, suggesting that ApoD plays a very fundamental role, and possesses a conserved regulatory mechanism. However, there also exist some specific regulatory elements, which are present only in certain species and may perform some special roles.ApoD mRNA expression in murine NIH/3T3 fibroblasts exposed to various stresses such as as hydrogen peroxide and UV light shows dose-dependent increase. And a fly homolog of ApoD, Glial Lazarillo, whose overexpression results in increased resistance to hyperoxia as well as a extension of lifespan under normoxia and resistance to starvation without altering lipid or protein content.

本文首先从生物信息学角度对分属于原生动物、无脊椎动物、头索动物和脊椎动物类群的10种动物ApoD的基因结构及调控区的调控元件进行分析及比较，发现：(1)ApoD基因外显子-内含子结构从原生动物草履虫到原口动物再到后口动物海胆的进化过程中不保守，但在分析的几种脊椎动物中相当保守；(2)文昌鱼ApoD基因扮演从无脊椎动物到脊椎动物承上启下的角色，可能代表了脊椎动物ApoD基因原型；(3)四个半胱氨酸保守位点在后口动物中都存在，而在原口动物中只存在两个，原口、后口动物ApoD蛋白一级结构上的差异反映蛋白功能上可能也存在一定差别；(4)调控区大多数主要调控元件为不同动物共有，说明ApoD主要功能及其表达调控在进化中相当保守；(5)ApoD基因个别调控元件是随着物种进化而出现并开始发挥相关作用，如SF-1；还有一些调控元件在进化过程中还没有发现其规律，这说明ApoD某些功能和基因表达调控模式可能因物种不同而存在一定的差异。

Compared with thermozyme,the first-class structure change of the psychrophilic enzyme can lead to space structure change and the structure of the enzyme is more flexible.Thus,this enzyme can catalyze with less energy in low temperature.

与嗜温酶相比，嗜冷酶一级结构的变化导致空间结构的变化，使酶分子的构象具有更大的柔性，同时也有利于这类酶在低温条件下需要更少的能量而发挥催化作用。
