International Weed Genomics Consortium


The International Weed Genomics Consortium (IWGC) provides a platform for private and public collaboration) to develop genomic tools and resources and to stimulate global research in weed biology and management.

Understanding evolutionary processes in weeds, such as resistance, stress tolerance, and gene flow, requires genomic resources and a trained workforce to analyze and implement innovation with this data.

The IWGC is addressing these challenges to develop the critical resources for major weeds through Academia and Industry research and training partnerships.

The IWGC will complete 10 weed genomes within three years in partnership with capability provider Corteva Agriscience through their genome technology core.

The main objectives of the consortium are:

  1. Obtain quality reference genomes for the most important weed species worldwide
  2. Provide user-friendly genome analytical tools and training through web-based databases and resources
  3. Facilitate inter-disciplinary collaboration and workforce development within this emerging field

The IWGC is hosting a weed genomics conference on September 22-24, 2021, in Kansas City, MO, with support from USDA-AFRI. The conference will be hybrid with in-person and virtual options, including hands-on training, keynote speakers, a poster session, and a workshop to prioritize weed genomics research objectives.

Training modules will include:

  • Molecular Biology 101
  • RNA-Seq pipelines
  • Mapping herbicide resistance and quantitative traits
  • Command Line 101
  • Population Genomics
