| 1. | Effects of arbuscular mycorrhizal fungi on plant secondary metabolism 丛枝菌根真菌对植物次生代谢的影响 |
| 2. | Secondary metabolism matters accumulated mainly during steady phage ( 24 - 30d ) 愈伤组织次生代谢物的积累主要在细胞增长周期的稳定期。 |
| 3. | Secondary metabolism matters synthetic and accumulated are also connect with growing condition 次生代谢物的合成与积累与光照条件有一定的联系。 |
| 4. | And when the callus cultured brightly , the three secondary metabolism matters content are higher than that of callus cultured darkly 光照培养下,三种次生代谢物的含量均高于暗培养。 |
| 5. | The growth circle and some physiology - biochemical indexes were illustrated . as the same time , the tendencies of flavonids , saponins and tea - polyphenols during growth circle are analysed . the paper provides scientific and experimental basis for cell culture and secondary metabolism matters yield 分析了在愈伤组织生长周期中山茶总黄酮、总皂甙和茶多酚的含量变化,为山茶的进一步开发,细胞培养和次生物质的生产提供理论和实验依据。 |
| 6. | Artemisinin , a sesquiterpene lactone containing an endoperoxide bridge , is a kind of phytoalexin . sa , a key signal molecular during systemic acquaired resistance ( sar ) , is related to the biosynthesis of phytoalexin . aba , a stress - resistance plant hormone can influence the secondary metabolism to stimulate phytoalexin biosynthesis 青蒿素属于萜烯类化合物(倍半萜类)是植保素( phytoalexin )的一种, sa是植物产生系统获得性抗性的重要信号分子,与植保素的产生相关。 |
| 7. | Among sequenced 16 positive clones randomly selected , two represent novel expression tag sequences , two are homologous to two unknown proteins in genbank ; the rest are homologous to known or putative proteins or enzymes with definite functions by searching the genbank through blast program , which are involved in various life activities of cell such as regulation of gene expression , plant secondary metabolism , signal transduction , adversity resistance , stress response and defense reaction . significant changes of quantities of these gene fragments were observed before and after ssh , which indicated they were enriched after ssh 随机挑选了16个差异表达的克隆进行序列测定,经与genbank数据库相关数据比较分析,发现有2个新的cdna片段( ets ) ,有12序列与genbank中已知蛋白或推测蛋白质( putativeprotein )序列有高低不同的同源性,它们参与基因的表达调控、植物的次生代谢、信号传导、抗逆、应激及防御反应等细胞生命活动过程。 |
| 8. | They show some physiology - biochemical indexes character during proliferation and cell activities . it is different between growth - circle of callus cultured brightly and that of callus cultured darkly . 3 . the change of secondary metabolism matters content : during growth circle , flavonids , saponins and tea - polyphenols were connected with callus growing condition 愈伤组织生长周期中生理生化指标的变化可溶性蛋白的变化、过氧化物酶( pod )活性的变化、超氧化物歧化酶( sod )活性的变化均与生长周期密切相关。 |
| 9. | This paper introduced the status and development of basic research on phytochemistry and natural product chemistry in the fields of searching bioactive components , biosynthesis and molecular regulation of plant secondary metabolism substance , environment influence on the synthesis and accumulation of plant secondary metabolism substance , the relationship of endophyte and plant secondary metabolism substance 摘要本文从生物活性成分的筛选与分离、植物次生代谢产物生物合成及其分子调控、环境因子对植物次生代谢产物合成和积累的影响、植物体内生菌与植物次生代谢产物的关系等方面介绍了我国资源植物化学与天然产物化学领域基础研究的现状与发展。 |
| 10. | This review is concerned with the studies on the type , synthetic way and reconcilement of plant secondary metabolism , with the emphasis of the development of matabolism in recent years and discussing the connection of it ' s pathway and biological function in detail to form a theoretical base for it ' s exploitation and utilization , and to gain deep insight into secondary metabolism 摘要简述了植物次生代谢产物的类型、合成途径及其代谢调节,重点阐述了次生代谢产物在最近几年的的学科发展,论述了植物的次生代谢途径与其生物学功能之间的关系,从而加深了人们对次生代谢产物的认识,对其开发利用提供理论依据。 |
