| 1. | Acbf is a transcription factor that combined with the ac - rich region of the promoter region . it has been cloned at arabidopsis thaliana , nicotiana tabacum and so on Acbf编码了结合在苯丙氨酸解氨酶启动子ac富集区上的一个转录因子, acbf基因已经在拟南芥、烟草等植物中得到了克隆。 |
| 2. | It was found that the levels of catechins and proanthocyanins in those subclones accumulating anthocyanins were also raised , and were independent of the activity of phenylalanine ammonia - lyase 发现积累色素的细胞系中,儿茶素与原花色素的形成能力也得到了大幅度提高,且与苯丙氨酸解氨酶活性无关。 |
| 3. | The effects of six effectors , polyethylene glycol ( peg ) 6000 , d - sorbitol , trehalose , dithiothreitol , glycerol and glutarie dialdehyd on pal activity in enzymatic reaction were investigated in this article 摘要实验考察了聚乙二醇6000 、 d -山梨醇、海藻糖、二巯基苏糖醇、甘油、戊二醛对酶反应中苯丙氨酸解氨酶活力的影响。 |
| 4. | Northern blot hybridization showed that leacbf expression had the same tendency with the enzyme activity . and it showed that the transcription factor acbf maybe have some relation with the enzyme activity of pal 表明在紫外光照射条件下, leacbf编码的转录因子的变化趋势与苯丙氨酸解氨酶( pal )活性的变化趋势有一定的相关性。 |
| 5. | Northern blot hybridization showed that leacbf has well - distributed expression in different tissues of wild tomato ( pink stage ) . treatment the seedling with uv made the enzyme activity of the pal increased gradually and then decreased 用不同的紫外线照射时间处理番茄幼芽,苯丙氨酸解氨酶( pal )的活性呈先是增加,达到最大值后再减小的趋势。 |
| 6. | This article reviews the distribution , basic characters , molecular structure , effects of a variety of factor on its activity and physiological function of pal in order to provide some references for its advanced research 摘要对苯丙氨酸解氨酶的分布、基本特性、分子结构、各种因子对其活性的影响和生理功能方面作了简要的概述,旨在为该酶的进一步研究提供参考。 |
| 7. | Phenylalanine ammonia - lyase ( pal ) can be induced by many kinds of factors including environment , plant hormone and so on . it has effect on the self - protection of plants . so they have a profound role in plant growth and development 苯丙氨酸解氨酶( pal )是一种诱导酶,许多环境条件以及植物激素对其活性都有不同程度的影响,它与植物抗逆有着极其密切的关系,对植物的生理意义非常重大。 |
| 8. | According to the conserved domain of the pal gene family , we achieved to the segment of pal gene about 950bp in rhodiola crenulata . some proposals were put forward for further development of the important enzymes in the metabolic pathway of salidroside 我们还根据苯丙氨酸解氨酶( pal )基因家族的保守序列,以大花红景天dna为模板,通过pcr扩增得到其约950bp长的pal基因的克隆,测序并比较了它与其基因家族的同源性。 |
| 9. | The biosensor is composed of an ammonia electrode and a phenylalanine ammonia - lyase ( pal ) coated hydrophobic gas - permeable membrane that separates the sample from the electrode internal solution . pal catalyzes phenylalanine to ammonia , which result the potential change of the electrode 将苯丙氨酸解氨酶固定化到氨气敏电极的透气膜上,制备成酶电极,苯丙氨酸解氨酶催化苯丙氨酸产生氨气,引起氨电极电位的变化。 |
| 10. | Abstract : the diferrences in cell growth , composition and levels of anthocyanins and catechins , activity of phenylalanine ammonia - lyase and dynamics of production between anthocyanin accumulating and non - accumulating subclones of tea cultured cells were examined 文摘:从细胞生长、色素和儿茶素次生产物组成与含量、苯丙氨酸解氨酶活性以及产物合成动态分析几方面,研究比较了积累色素与不积累色素的两类茶树培养细胞系之间的差异。 |
