Jackfruit (Artocarpus heterophyllus), Moraceae), is an important crop of South East Asia. Previous work by students in the Zerega Lab have measured the genetic diversity of plants from both India and Bangladesh. We are looking for a student to add Malaysian and Thai samples to this dataset to look at changes in diversity across the range. This project will largely consist of DNA extraction, PCR amplification of microsatellite loci, microsatellite analysis on a Beckmann capillary-action DNA analyzer, and analysis of microsatellite data using bioinformatic tools.
