Management of the Tissue Collection

Within this project I am working towards the development and implementation of new standards for optimised access and conservation of plant tissue samples stored in silica gel. Silica gel dried tissues complement herbarium specimens and often provide the best source of high quality DNA for molecular analysis. Standardized methods for collecting, long-term storage, retrieval and distribution of these tissue samples are essential for the best results in future research applications. I am carrying out research to improve protocols for each of these steps. Many specimens in our tissue bank represent rare and endangered species from difficult to access regions of the world, including unique samples from a diversity of taxonomic groups. The Tissue collection is a centrally managed repository, and aims at managing access and security in a consistent and user friendly manner. I am also part of the team which is running our DNA bank and both activities are directly linked.
