Conclusions
Our primers will be useful in improving resolution at shallow depths across the Thelypodieae, and likely in other Brassicaceae.
Results
We selected regions based on a cross-referenced matrix of previous studies and public Brassica expressed sequence tags. To design primers, we used alignments of low-depth-coverage Illumina sequencing of genomic DNA for two species of Brassica mapped onto Arabidopsis thaliana. We report several primer combinations for five regions that consistently amplified a single band and yielded high-quality sequences for at least 70% of the species assayed, and for four additional regions whose utility might be clade specific. • Conclusions: Our primers will be useful in improving resolution at shallow depths across the Thelypodieae, and likely in other Brassicaceae.
