The volume focuses on various methods used to generate, process and analyze EST Format: Hardcover.

Expressed sequence tag analysis. Expressed sequence tags (ESTs) are randomly selected clones sequenced from cDNA libraries. Each cDNA library is constructed from total RNA or poly (A) RNA derived from a specific tissue or cell, and thus the library represents genes expressed in the original cellular population.

To date, over 45 million ESTs have been generated from Cited by: Over the past two decades, expressed sequence tags (ESTs - single pass reads from randomly selected cDNAs), have proven to be a remarkably cost-effective route for the purposes of gene discovery.

Thus, partial sequence information from a gene of interest can be used to search for either corresponding cDNAs or genomic DNAs which may reside in a publicly accessible database.

This can lead to.Many plant ESTs have been sequenced as an alternative to whole genome sequences, including peanut because of the genome size and complexity. The US peanut research community had the historic Atlanta Genomics Workshop and named the EST project as a main priority.
