Crops are incredibly diverse at the level of their DNA and how they grow in the field. We sequence crop genomes to understand this diversity of DNA, and we measure millions of plants in the field to understand how this DNA diversity generates differences in the ways plants look and grow. In order to conduct these experiments, we often create germplasm that mixes the diversity of maize varieties from around the world.
Did you know that any two maize varieties are far more genetically different that people are from chimpanzees?
genotyping by sequencing(GBS)
There are hundreds of thousands of varieties of crops that are developed and tested every year. GBS is a cheap and efficient process for measuring and tracking genetic variation for both breeding, genetics, and conservation biology. We develop bioinformatics (e.g. TASSEL-GBS and Practical Haplotype Graph) to work with this data.
