Construction and analysis of full-length and normalized cDNA libraries from citrus.

We have developed an integrated method to generate a normalized cDNA collection enriched in full-length and rare transcripts from citrus, using different species and multiple tissues and developmental stages. Interpretation of ever-increasing raw sequence information generated by modern genome sequencing technologies faces multiple challenges, such as gene function analysis and genome annotation. In this regard, the availability of full-length cDNA clones facilitates functional analysis of the corresponding genes enabling manipulation of their expression and the generation of a variety of tagged versions of the native protein. The development of full-length cDNA sequences has the power to improve the quality of genome annotation, as well as provide tools for functional characterization of genes.
