Abstract:
This study demonstrates that cDNA-AFLP is a powerful gel-based genome-scale transcript profiling technique to generate quantitative gene expression profiles for eQTL mapping. We used cDNA-AFLP to monitor the relative abundance of 912 transcripts across 50 Arabidopsis thaliana recombinant inbred lines. Estimates for heritability of cDNA-AFLP intensity polymorphisms were high, with a median of 0.30 and an interquartile range of 0.21-0.44. A total of 198 expression polymorphisms were significantly linked to specific chromosomal regions (P < 0.05). Both cis- and trans-acting loci correlated with the variation in gene expression levels were found. Some of the trans-acting loci correlated to multiple expression polymorphisms, suggesting trans-acting alleles with widespread transcriptional effects. Here, we have illustrated that cDNA-AFLP constitutes a powerful transcript profiling method that can be utilized for 'multifactorial genomics' analysis of any plant or animal species for which segregating populations and molecular marker maps are available.

The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
