GnpIS is a powerful multispecies centralized database information system dedicated to plant, trees and their bioagressors (fungi). It is composed of a set of relational databases, each optimized according to one data domain and connected together to be search as a whole or by theme. Its originality is to bridge genetic and genomic data, allowing researchers and breeders to cross genetic information (i.e Genetic maps, QTL, markers, SNPs, Germplasms, Genotypes) with genomic data (i.e. physical maps, genome annotation, expression data) for species of agronomical interest. One key feature of the system, is the availalibility of two tools allowing to query through all these databases simultaneously, a quick search tool based on Lucene technologies and an advanced search tool based on Biomart software (GMOD). The system is generic for any kind of species.
