茶条槭 细胞生长 没食子酸 悬浮培养
2009/11/18
初步建立茶条槭(Acer ginnala)细胞悬浮培养体系: 以茶条槭子叶为外植体, 接种于WPM培养基中, 对茶条槭愈伤组织进行诱导和继代培养。悬浮培养中, 每代增长指数达到11.6, 没食子酸含量达到1.518%。通过对比NT、IS、WPM、B5和MS培养基所含成分对茶条槭愈伤组织悬浮培养的影响, 综合考虑悬浮细胞的生长速率和有效成分的含量, 确定WPM为基本培养基。WPM培养基大量元素的浓度...
苔藓植物小立碗藓，功能基因组学研究新的模式系统 The Moss Physcomitrella patens, a New Model System for Functional Genomics
功能基因组学 反求遗传学 基因打靶 模式系统 苔藓植物 小立碗藓
2008/1/8
摘要
苔藓植物具有相对简单的发育模式，单倍体的配子体在其生活史中占主导地位，作为研究植物生物学过程的模式系统具有诸多的优越性。苔藓植物小立碗藓能够高效地通过同源重组的方式将外源核酸整合到其核DNA，这就使得基因打靶在此物种中就像在小鼠胚胎干细胞和酵母中一样成为一个非常便利的技术。另外由于小立碗藓与高等植物在生物特征上有很大相似之处加之其有其他诸多优越性，它有望成为一个诱人的植物生物学和功能基因组...
植物数量性状遗传体系的分离分析方法研究Segregation Analysis of Genetic System of Quantitative Traits in Plants
植物数量性状 主基因-多基因遗传模型 分离分析
2008/1/6
摘要
在传统的数量性状多基因遗传模型基础上提出主基因-多基因遗传模型具普遍性，纯主基因或纯多基因遗传模型只是其特例。由此初步建立了植物数量性状遗传体系分离分析方法。目前该方法可以检验2～3个主基因的个别遗传效应、多基因整体的遗传效应和两者的遗传率。本文介绍这种分离分析方法的研究经过、主要进展及应用效果，并以实例说明其分析步骤、方法和效果。Abstract: Based on the trad...
植物防御系统中抗病相关基因的研究进展Recent Advances in Research on Disease Resistance Genes in Defence System of Plant
R基因 R蛋白 无毒基因 基因克隆
2007/12/29
本文论述了植物防御系统中抗病相关基因（resistance gene,R基因）的研究进展。列表总结了迄今已克隆的R基因，并将其归为四种不同的类型。综述了不同基因表达产物-R蛋白在细胞中的定位及其相应的功能。此外，还对R基因编码区的多态性、R基因在染色体上排列方式以及R基因的进化与起源等问题进行了讨论。
