Potato Genomics

As co-lead of the Genome Canada "Canadian Potato Genome Project" in 2001, we created many resources for potato genomics, including EST sequences, a large activation tagged population, and contributed to the sequencing of the potato genome.

 

Our current research is focused on the following:

1. Gene discovery based on activation tagged lines related to tuber quality and potato disease

2. Investigating the impact of abiotic stress, such as heat, on the development of potato tubers
