南京农业大学专利:一种使用序列k-mer频率优化特征精准识别土壤致病菌污染的方法
序列k-mer频率 精准识别 土壤 致病菌污染
2023/11/27
本发明公开了一种使用序列k?mer频率优化特征精准识别土壤致病菌污染的方法,其步骤为:步骤一、选取合适的k?mer片段长度,进行频率特征提取;步骤二、对提取的数据进行归一化处理;步骤三、构建交叉融合神经网络;网络由输入层、残差网络、深度网络、交叉网络和特征合并层组成;步骤四、模型预测;第一次使用先训练神经网络参数,再将待预测细菌DNA序列通过步骤一方法提取频率特征,送入训练好的残差神经网络,输出预...
目的 使用流式细胞术与K-mer分析估测黄芪基因组的大小及复杂程度,为黄芪基因组测序奠定基础。方法 以番茄为内标,用流式细胞仪测定经碘化丙啶(PI)染色的番茄细胞核和黄芪细胞核混合样品的PI荧光强度,通过比较黄芪与番茄细胞DNA含量峰值的倍数关系,计算黄芪的基因组大小。采用高通量测序技术进行黄芪基因组调查测序,利用生物信息学方法估计黄芪杂合率、重复序列和GC含量等信息。结果 采用流式细胞术测得黄芪...

在过去的几十年中,人们往往使用高度保守的基因家族进行系统进化分析,采用全基因组序列进行系统进化分析并不普遍。目前,基于是否进行序列的比对,分子系统发生树的构建分为两类。其中,不需要进行序列比对的方法是依据K-mer向量计算的距离矩阵进行系统进化分析,大量的研究证实该算法是行之有效的,尤其是对基因组中诸如蛋白编码序列等的特定区域。不仅如此,K-mer算法还在组学的其他方面,包括基因组组装、motif...

应用70 mer Oligo基因芯片从限制性cDNA片段中钓取目的基因
2007/7/25
构建cDNA文库,并从中钓取基因是目前常规获得目的基因的方法之一,但构建文库的工作量大,重复机会多,常常造成人力、物力上的浪费。随着核酸合成技术的进步,长链寡核苷酸(oligo)的人工合成成为可能。统计分析表明,一条长度为70 bp的特异性oligo片段足以代表一个基因[1]。在本研究中,我们利用固化到玻片上的70 mer oligo作为探针,直接从本室创建的限制性显示技术[2][3](restr...
