The Relevance of Pedigree and Genomic-based Conservation Management to Exceptional Plant Species: A Case Study Using Amorphophallus titanum

Description
As many plant species around the world are threatened with extinction, botanic gardens play an increasingly important role in conservation efforts by managing species across ex situ collections. However, a lack of best practices outlining the collective management of living collections among continents, termed continental collections, jeopardizes the long term stability of ex situ conservation collections. No research to date has explored a botanic management plan using pedigree and empirical genetic data to minimize relatedness between individuals, maximize founder representation, and preserve genetic diversity. To address this gap, we will be comparing the effectiveness of pedigree and genomic data for the management of Amorphophallus titanum, an exceptional species commonly cultivated in the botanic community. Amorphophallus titanum is an ideal focal species to implement this protocol on given its lack of genetic exchange between continental collections. Anticipated results will compare breeding recommendations, for both within and between continental collections, and estimated metapopulation genetic parameters derived from the pedigree and genomic data using PMx, a zoo management software. This study will be an important first step in bettering collections management for this endangered plant species and in the design of more successful breeding programs for other exceptional species worldwide.
