RADseq as a valuable tool for plants with large genomes-A case study in cycads.

Full genome sequencing of organisms with large and complex genomes is intractable and cost ineffective under most research budgets. Cycads (Cycadales) represent one of the oldest lineages of the extant seed plants and, partly due to their age, have incredibly large genomes up to ~60 Gbp. Restriction site-associated DNA sequencing (RADseq) offers an approach to find genome-wide informative markers and has proven to be effective with both model and nonmodel organisms.
