Thoughts on sequencing strategy

Lex Nederbragt (corr) et al.

When setting up a strategy for sequencing/assembly these are valuable to know:

  • the goal of the project, e.g.
  • gene-mining
  • presence/absence of genes
  • long scaffolds for synteny
  • reference genome-standard (whatever that is)
  • strain variation/haplotying
  • genome size
  • genome complexity, i.e. repeat content and level of heterozygosity
  • number of chromosomes, extrachromosomal elements
  • can a pure sample be obtained or will there be contaminating DNA?
  • how much DNA can be obtained from a single individual/clonal line or will it be necessary to use DNA from a mix of different individuals (read: different genomes)?
  • is there sequencing data available from the same individual or species?
  • how close is the most closely related reference genome?
