Abstract
With a long-term goal of constructing a linkage map of Rhododendron enriched with gene-specific markers, we utilized Rhododendron catawbiense ESTs for the development of high-efficiency (in terms of generating polymorphism frequency) PCR-based markers. Using the gene-sequence alignment between Rhododendron ESTs and the genomic sequences of Arabidopsis homologs, we developed ‘intron-flanking‘ EST–PCR-based primers that would anneal in conserved exon regions and amplify across the more highly diverged introns. These primers resulted in increased efficiency (61% vs. 13%; 4.7-fold) of polymorphism-detection compared with conventional EST–PCR methods, supporting the assumption that intron regions are more diverged than exons. Significantly, this study demonstrates that Arabidopsis genome database can be useful in developing gene-specific PCR-based markers for other non-model plant species for which the EST data are available but genomic sequences are not. The comparative analysis of intron sizes between Rhododendron and Arabidopsis (made possible in this study by aligning of Rhododendron ESTs with Arabidopsis genomic sequences and the sequencing of Rhododendron genomic PCR products) provides the first insight into the gene structure of Rhododendron.
