Construction of cDNA Libraries: Focus on Protists and Fungi

Sequencing of cDNA libraries is an efficient and inexpensive approach to analyze the protein-coding portion of a genome. It is frequently used for surveying the genomes of poorly studied eukaryotes, and is particularly useful for species that are not easily amenable to genome sequencing, because they are nonaxenic and/or difficult to cultivate. In this chapter, we describe protocols that have been applied successfully to construct and normalize a variety of cDNA libraries from many different species of free-living protists and fungi, and that require only small quantities of cell material.
