李红叶 柑橘枝干病害病原真菌多样性
2022/10/14
柑橘是世界上最大宗水果，我国是世界上最大的柑橘生产和消费国。枯梢，流胶、腐烂、溃疡和开裂是我国柑橘上常见的枝干病害，但对诱发其发生的病原菌种类一直缺少系统性研究，以往其病原被简单地归咎于树脂病(Diaporthe citri)和炭疽病(Colletotrichum gloeosporioides)。实际并非如此。2017-2020年，浙江大学农学院李红叶教授课题组从我国柑橘主产区广泛收集枝干病害样...
In this work we present the development of a workflow based on Taverna which is going to be implemented for calculations in Phylogeny by means of the MrBayes tool. It has a friendly interface develope...
In the small phylogeny problem we, are given a phylogenetic tree and gene orders of the extant species and our goal is to reconstruct all of the ancestral genomes so that the number of evolutionary op...
Fast error-tolerant quartet phylogeny algorithms
Fast error-tolerant quartet phylogeny algorithms
2010/11/15
We present an algorithm for phylogenetic reconstruction using quartets that returns the correct topology for $n$ taxa in $O(n \log n)$ time with high probability, in a probabilistic model where a quar...
Molecular Phylogeny of the Gayal in Yunnan China Inferred from the Analysis of Cytochrome b Gene Entire Sequences
Gayal (Bos frontalis) Cytochrome b Gene Molecular Phylogeny
2016/4/27
The gayal (Bos frontalis) in China is a very rare semi-wild and semi-domestic bovine species. There still exist remarkable divergences on the gayal??s origin and taxonomic status. In the present study...
柴达木山羊群体遗传结构及系统地位的研究Genetic Structure and Phylogeny Status of Chaidamu Goat Population
柴达木山羊 遗传检测 系统地位
2008/1/6
摘要采用简单随机抽样法对柴达木山羊群体进行了遗传检测，从毛色、外型特征、体尺、血液蛋白与DNA多态性等5个方面进行了群体遗传结构分析，并探索了其系统地位。结果表明：(1)毛色和形态特征的平均表型异质度分别为0.3419、0.5207；(2)血液蛋白在6个基因座上具有多态性，平均基因座杂合度为0.2584；(3)DNA-RAPD标记表现丰富的多样性，基因多样度为0.4085～0.5318。通过对柴达...
孔雀活化素基因(activin)ßA 亚基成熟肽序列的分子克隆及其对白孔雀起源与分类的佐证分析Molecular Cloning of Activin ßA Subunit Mature Peptide from Peafowl and Its Application in Taxonomy and Phylogeny
孔雀 活化素基因 系统发生 分类 peafowl activin gene phylogeny taxonomy
2007/12/5
摘要参考已经克隆的活化素(activin)基因βA亚基成熟肽序列，设计一对兼并引物，从绿孔雀(pavo muticus)、蓝孔雀(pavo cristatus)和白孔雀基因组中克隆到活化素基因βA亚基成熟肽序列。测序结果表明，活化素基因βA亚基成熟肽序列长345bp，编码115个氨基酸。序列分析表明，蓝孔雀与绿孔雀核苷酸同源性为98.0%，而蓝孔雀与白孔雀核苷酸同源性为98.8%。NCBI收索结果...
