Researchers at Michigan State University, in a collaborative effort, have successfully mapped the genome of the Montmorency tart cherry, a significant development for the cherry industry. The project aimed to identify genes linked to late blooming, a critical adaptation to climate change, especially in Michigan. However, the research uncovered the complex allotetraploid nature of tart cherries, with four sets of chromosomes from two ancestral species, adding to its genetic complexity. The team is now using this information to understand bloom time, fruit traits, and to develop cherry varieties that are resilient to spring weather variations. This breakthrough is expected to boost tart cherry research and breeding globally, potentially leading to more resilient and productive cherry trees.
