A Structural, functional and comparative annotation platform dedicated to plants 'and their bio-aggressors' genomes

GnpAnnot is a ANR project on green genomics which intends to develop a community system of structural and functional annotation supported by comparative genomics and dedicated to plant and bio-aggressor genomes allowing both automatic predictions and manual curations of genomic objects.

Crops are the major source of food. Up to 30% of crop yield is lost due to pests and pathogens. In the era of high throughput technology, the number of plant and bioaggressor genomes sequenced partially or completely increases exponentially. Gene annotation is a crucial step in nucleic sequence analysis which needs to define gene structure, protein function and homology relationships. While variations exist between eukaryotic species, generally genome annotation is a hard task for many reasons: large genomes, polyploidy, high proportion of non coding DNA and repeats, mosaic gene structure (intron/exon). Gene finder softwares are improving but they cannot replace manual annotation. Systems have been developed to help genomic data curation, but none of them satisfy all following requirements:

  • manual structural, functional and comparative annotation of eukaryotic genes
  • database, analysis pipeline and annotator Web interfaces
  • genericity, modularity, portability, sustainability and compatibility.

CIRAD, INRA and Bioversity uses to work together, and they propose to mutualize theirs efforts to develop and use a platform which allows users to annotate automatically or manually, to browse genomes, and to perform genome comparative analyses. The work will be divided into five work packages:

  • database and flow management
  • annotator interface implementation
  • interoperability with other systems
  • sequence exploitation and platform release
  • manual annotation and platform validation.

This platform will be exploited immediately on well identified sequencing projects studying genome structure and evolution and/or researching genes of agronomical interest. Four platform instances will be released on three sites: monocots (CIRAD Montpellier), insects (INRA Rennes), fungi (URGI Versailles) and wheat-grape (URGI Versailles).
