Eggplant gap analysis data

This dataset is is a csv file of occurrence data from museum/herbarium and germplasm banks used to analyze gaps in collection and representation of eggplant (_Solanum melongena_) in germplasm collections worldwide. The data comprise taxon identity, source(provider and whether G [germplasm bank] or H [herbarium]), and geographical coordinates.

Abstract of the paper here:

Premise of the study. Crop wild relatives (CWR) provide important traits for plant breeding, including pest, pathogen and abiotic stress resistance. Their conservation and future availability are essential for food security. Despite this, the world's genebanks are currently thought to conserve only a fraction of the total diversity of CWR.

Methods. We define the eggplant genepool using the results of recent taxonomic and phylogenetic studies. We identify the gaps in germplasm accessions for eggplant (Solanum melongena L.) CWR by comparing georeferenced herbarium records and germplasm accessions using a gap analysis methodology implementing species distribution models (SDM). Preliminary conservation assessments using IUCN criteria were done for all species and were combined with the gap analysis to pinpoint where under-collected and threatened CWR species coincide with high human disturbance and occur outside of protected areas.

Key results. We show that many eggplant CWR are poorly represented in genebanks compared to their native ranges. Priority areas for future collection are concentrated in Africa, especially along the Kenya-Tanzania border. Fourteen species of eggplant CWR are assessed as threatened or near-threatened; these are also concentrated in eastern Africa.

Conclusions. The knowledge base upon which conservation of wild relative germplasm depends must take into account both taxonomic and phylogenetic advances. Beyond traditional research focus on close relatives of crops, we emphasize the benefits of defining a broad CWR genepool, and the importance of assessing threats to wild species when targeting localities for future collection of CWR to improve crop breeding in the face of environmental change.
