  • New video: Crop biodiversity for healthy, nutritious livelihoods

    Erratic weather, poor soil health, and resource shortages keep millions of maize and wheat farmers in developing countries from growing enough to feed their households and communities or to harvest a surplus to sell.

MasAgro Biodiversity, a component of the Sustainable Modernization of Traditional Agriculture (MasAgro) program, focuses on the utilization and conservation of valuable genetic resources with genetic diversity protected in germplasm banks. This program has the purpose of accelerating the development of Varieties of maize and wheat that can meet the nutrition and nutritional demands of a growing population, facing the challenges of climate change.

By characterizing the genetic configuration of CIMMYT germplasm bank collections, the evaluation of priority characteristics – such as drought tolerance, high temperatures and some diseases – and the development of bioinformatics tools that streamline its analysis, MasAgro Biodiversity has Generated a “platform for the utilization of genetic resources” of maize and wheat.

This platform puts several products at the disposal of the scientific community. MasAgro Biodiversity also offers some services in order to promote equity in access and benefits of the use of maize and wheat diversity.

SeeD is perhaps the most comprehensive genebank-characterization effort globally to this date. We are going to characterize the genetic makeup of up to 200,000 DNA samples from genebank accessions and introgression populations/lines. We will also characterize accession subsets of varying size and composition for a set of priority traits and breeding targets.

Such an ambitious project would be impossible without a solid foundation in two key enabling technology areas:

  • A robust, high-throughput genome-

    profiling platform that accurately characterizes unknown genetic diversity, is ‘forward compatible’ with evolving genotyping technologies, and enables the standardized analysis of accessions from different genebanks at different times.

  • A state-of-the-art software platform to collect, standardize, store, query, visualize, and analyze the ‘tsunami’ of data we expect SeeD participants to generate – ideally made of modules that can be repackaged so that SeeD clients can install and use these software tools themselves to more effectively utilize  SeeD data.

Given the critical nature of these enabling technologies, we have formed strategic partnerships with two organizations that have a proven track record of delivering solutions that are being readily adopted by their clientele, Diversity Arrays Technology (DArT) and the bioinformatics group at the James Hutton Institute (JHI).

The primary objective of our partnership with DArT is to establish and operate a joint Genetic Analysis Service (SAGA for its Spanish acronym: Servicio de Análisis Genético para la Agricultura) at the National Center for Genetic Resources (CNRG). SAGA will initially focus on analyzing DNA samples for SeeD and other MasAgro components, using genotyping-by-sequencing (GBS) technologies, while simultaneously building capacities in configuring modern genomics tools to fit applications in demand-driven agricultural research. In the medium term, we envision that SAGA operations should become self-sustaining to support applied agricultural research in Mexico and the region beyond the duration of the SeeD project and the crops targeted by SeeD by offering a combination of genetic-analysis and value-adding information-management services.

Information management presents a serious challenge for a project like

SeeD. We are working with both DArT and JHI to co-develop a modular software platform for the SeeD project (SeeDB for ‘SeeD database’).

The entire SeeDB platform, including all its components and modules (for example for field data collection, will be made available for free. The code will be released under an Open Source license, starting with the first production version.

Project participants have developed a number of publicly available resources to facilitate the visualization and analysis of data.

Helium is an example of a useful visualization tool developed by SeeD collaborators that allows trait and characterization data to be painted onto a pedigree tree. This tool won the best paper award at BioVis 2014 in Boston, USA. A freely available video and a presentation demonstrate the use of this program.

PHILOSOPHY OF OUR APPROACH

PHILOSOPHY OF OUR APPROACH

So many accessions, so few data!

Many genebanks resemble libraries that lack sufficiently informative catalogs. The advent of next-generation DNA-sequencing platforms has made it possible to characterize the genetic diversity conserved in entire genebanks.

Information management

Generating new data by itself is insufficient if it cannot be effectively disseminated, queried, summarized, visualized, and analyzed. Data generation, therefore, has to go hand-in-hand with providing intuitive software and analysis tools to deal with the rapidly expanding datasets describing maize and wheat genetic resources.

Pre-breeding

A ‘reformatting’ of the diversity in genebanks into a more breeder-ready format could lower the barriers to mobilize novel genetic variation into breeding programs, which in good part are due to the dependency of gene effects on genetic backgrounds.

Traits with complex genetic architecture

Some of the most important challenges to agriculture need to be addressed by manipulating genetically complex characters controlled by small-effect alleles (yield potential, heat and drought tolerance, etc.).

Collecting germplasm.

The availability of sufficient numbers of genebank accessions does not appear to be a factor limiting the use of novel genetic variation in breeding programs, and a new initiative will secure the global network of genebanks of humanity’s major food crops for future generations.
