One potato genome unravelled, three to go
A massive collaboration among scientists on four continents has now solved the problem of potato genome to decode by growing a whole plant in culture from one pollen cell. This produced potatoes with just one copy of the genome, which the researchers were able to sequence. The "monoploid" sequence provided a template they could then use to piece together the DNA sequences of a rare potato variety which is diploid, meaning it carries two genomes.
