Goals and Objectives:

Aim-3: Develop an online informatics portal and data warehouse for ontology-based, annotated plant genome data and plant genomes.

  • Deliverables: A centralized portal for common reference ontologies for plants and the associated data sets. Novel data store and web user interface.

3.1 Planteome Web Portal Development

  • Drupal portal will host the AmiGO browser, the ontology database (similar to the one developed by the PO and the GO), and a BioMart
  • Transition to AmiGO 2.0 with new features

3.2 Planteome Data Warehouse Development

  • Novel data warehouse for storing both the ontologies and annotation data based on NoSQL (e.g. MongoDB,, and Apache™ Hadoop®,
  • Integrate the MapReduce algorithm to increase scalability and performance
  • Investigate using HDF (Hierarchical Data Format), as a storage format for any numerical or sequence-based data.
  • Create an efficient way to add annotations incrementally to the database, (not possible in the current AmiGO database)
  • Implementation of OLAP (Online Analytical Processing) data cubes (

3.3 Integration with the iPlant infrastructure

  • Initial design and testing will happen locally at the Center for Genome Research and Biocomputing at Oregon State University
  • Use of virtual machine (VM) images in the iPlant cloud computing environments
  • Utilization of high performance computing resources, such as:
    • The supercomputer 'Stampede' at Texas Advanced Computing Center (TACC)
    • Use of iRODS at iPlant for data file storage and retrieval
    • Image hosting via Bisque hosted on the iPlant infrastructure (See 3.4, below)
  • Interaction with resources such as CoGE, Bisque, and the Integrated Breeding Platform (IBP)

3.4 Library of Publicly-Accessible, Annotated Digital Images

  • Design a relational data schema to support the large-scale storage of annotated images (and their associated metadata)
  • Image library main goal: A training set for a new auto-segmentation and annotation active-learning algorithm
  • Support other visual analysis tools and the integration of image data with ontology data
  • Will also function as a home for community-contributed image data

3.5 Application Programming Interface (APIs)

  • Develop of publicly available APIs for both internal and external data access to ontology terms and annotations
  • Extend the existing lightweight web services providing Plant Ontology terms, synonyms, and definitions to the Planteoem APIs, including direct web service access to annotated data
  • Potential Users:
  • Integrate our data with other external APIs, For example:
    • EBI (the Gene Expression Atlas, Ensembl Plants, IntAct),
    • ERA-CAPS (genotype-to-phenotype data)
    • DOE KBase
    • GCP Integrated Breeding Platform
    • Agave on iPlant which provides web-focused developer access to the iPlant data store and other integration services, providing a direct link to high-performance computing systems such as the TACC.
