To find additional evidences for the newly identified miRNAs, the expression of the precursors were tested by BLAST analysis with existing expressed sequence tag (EST) database.
The EWP scale was: Green: no current perceived shortage - sufficient workforce for existing expressed service demand, minimal number of vacancies, no difficulty filling positions, and short waiting times.
However, both of these methods rely primarily on existing expressed gene sequences for the synthesis of oligonucleotides and for generating qRT PCR primers.
From existing expressed sequence tag (EST) resources and three new full-length cDNA libraries, 9,057 reference quality full-length gene insert clones were identified for Atlantic salmon.
Analysis of the existing expressed sequence tag (EST) data suggests that a protein-coding locus can produce at least 5.7 different transcripts [ 1, 8].
Here, existing expressed sequence data of the bovine T. foetus is augmented and we leverage the field by providing the first comprehensive expressed sequence library of a feline T. foetus genotype.
Assembly of new 454 cDNA sequences with existing expressed sequence tag (EST) contigs from the Ambystoma EST database more than doubled (3935 to 9411) the number of non-redundant human- A. mexicanum orthologous sequences.
Another approach to mining molecular markers, involving in silico methods, has also been successful; examples include the derivation of markers from a draft genome [ 12] and the mining of existing expressed sequence tag (EST) libraries [ 13].
We develop the first dense meiotic map for sockeye salmon using a combination of novel SNPs found in restriction site associated DNA (RAD tags) and SNPs available from existing expressed sequence tag (EST) based assays.
This sequence diversity of the potato genome has been long documented through the characterization of SNPs in its transcriptome, either by bioinformatic mining of existing expressed sequence tag databases [ 9, 10] or by active sequencing of cDNAs and selected genes in cultivar panels [ 11- 13].
Due to the low degree of sequence annotation, the combination of microarray and 454 sequencing analysis yielded only a limited number of new contigs after assembly of 454 cDNA sequences with existing expressed sequence tags (ESTs) even though the number of non-redundant human- A. mexicanum orthologous sequences was increased considerably [ 18].
