EST (Expressed Sequence Tag)表达序列标签est作为表达基因所在区域的分子标签因编码dna序列高度保守而具有自身的特殊性质与来自非表达序列的标记如aflprapdssr相比更可能穿越家系与种的限制因此est标记在亲缘关系较远的物种间比较基因组连锁图和比较质量性状信息是特别有用 EST (Expressed Sequence Tag)表达序列标签 EST ...
db EST(expressed sequence tag database)【答案】:表达序列标签数据库。是GenBank中的一个子数据库,包含来源于不同物种的表达序列数据和表达序列标签序列的其它信息。
Expressed sequence tags (ESTs) were a first step in the project to sequence the human genome. The EST initiative was an attempt to examine diversity of gene expression by sequencing 5′ and 3′ ends of cDNAs from multiple mammalian tissues (Adams et al., 1991, 1995). These databases includ...
Expressed sequence tags (ESTs) are randomly sequenced cDNA clones. Currently, nearly 3 million human and 2 million mouse ESTs provide valuable resources that enable researchers to investigate the products of gene expression. The EST databases have proven to be useful tools for detecting homologous gen...

1.61. BLAST searching was performed by using a minimum alignment length of 40 bp with a score > 80 as recommended for EST mapping across species and two E-value thresholds (E ≤ 10−10 and E < 10−5) [26, 32, 67]. Turbot marker sequences were also used as queri...
For eukaryotic genes, long introns can cause long gaps in sequence alignments, which significantly reduces the efficiency of short word filtering. So, practically, cd-hit-est can be applied only for non-intron-containing sequences, such as ESTs. What is dbEST(Expressed Sequence Tags) Expressed ...
Expressed Sequence Tag Simple Sequence Repeats (EST-SSRs), also known as transcriptome-derived SSRs, are microsatellite markers extracted from expressed sequence tags (ESTs) of transcriptome RNA sequences located explicitly in the exons of cDNA sequences. Compared to microsatellite sequences located in...

Expressed sequence tag (EST) sequencing projects are underway for numerous organisms, generating millions of short, single-pass nucleotide sequence reads, accumulating in EST databases. Extensive computational strategies have been developed to organize and analyse both small-and large-scale EST data for ...
