基于多信息融合的酵母重组冷热点预测
重组热点 k-mer频数热力学稳定性 核小体占据率
2014/4/22
减数分裂重组并非均匀发生在基因组上，而是在一些区域有着较高的重组频率（重组热点），在另一些区域重组频率较低（重组冷点）. 重组的发生不仅与序列特征有关，还依赖于染色质的结构. 准确鉴定重组热点和冷点对于认识重组发生的分子机制以及基因组进化规律具有重要意义. 本文首先在实验数据的基础上识别2 kb尺度的重组冷热点，然后采用多样性增量结合二次判别分析（IDQD）和支持向量机（SVM）算法，基于一系列与...
一种新沼泽红假单胞菌鉴定及其类胡萝卜素含量分析
沼泽红假单胞菌 鉴定 类胡萝卜素
2014/3/18
通过观察实验室保藏的光合细菌X1的表观形态、生理特性以及采用16S rDNA序列对比的方法进行鉴定,采用超声波破碎法、酸-热破壁法和研磨法对X1中类胡萝卜素进行提取,并比较各种方法效果.用丙酮作为提取剂,进一步利用紫外分光光度法、薄层层析法和高效液相色谱(HPLC)法对类胡萝卜素提取液进行了分析.确定光合细菌X1属于紫色非硫细菌中的红罗菌科、红假单胞菌属,沼泽红假单胞菌(Rhodopsedomon...
鸳鸯鸭恒定链两异构体组织转录模式研究
实时相对定量PCR 特异性转录
2014/12/29
为探索鸳鸯鸭恒定链（MDIi）两种异构体MDIi-1和MDIi-2在不同组织或器官中的转录模式，建立了检测MDIi-1和MDIi-2组织转录的实时相对定量PCR方法，检测并分析了MDIi-1和MDIi-2在不同组织或器官中的转录特点。结果显示MDIi-1在法氏囊底部的转录水平为各组织或器官中最低(设为校正器)；和校正器比较，MDIi-1在脾和小肠黏膜呈最高水平转录，而法氏囊颈部、肝、肾、胸腺和血液...
