Apple and Potato Genomics
The Tong lab is interested in genotype x environment interactions, especially in regard to two traits - apple fruit crispness and red coloration of potato peels due to anthocyanin biosynthesis. The researchers use next generation RNA sequencing to better pinpoint genes that may be involved in Honeycrisp apple fruit crispness maintenance. They also use a full-sib breeding population with Honeycrisp as a parent to study the expression of these genes. With regard to potatoes, The lab uses next generation DNA sequencing to determine how anthocyanin genes have changed when the Norland potato variety mutated into its color sports Red Norland and Dark Red Norland. MSI resources are used to analyze the data generated from these studies.
