Amaizing is a long-term public-private research initiative coordinated by Alain Charcosset, INRA UMR Génétique végétale, Moulon, France. The overall objective of AMAIZING is to improve the efficiency of maize breeding programs in France, and to further characterize the varieties by implementing biotechnology advances and developing tools, biological knowledge, reference data and strategic know-how. Specific emphasis will be put on better understanding of genome structure and diversity organization, gain insights in the genetic determinisms of drought and cold tolerance, nitrogen use efficiency and the analysis of heterosis in view of developing optimized varieties and associated cultivation practices. Basic knowledge on diversity, resources and approaches developed within the project also will be beneficial to target traits investigated in other projects.Especially, AMAIZING will produce a genome sequence based and breeder oriented tool box that will enable a breakthrough in the following fields

Project details

Duration: 01/07/2011 to 31/12/2019

Coordinator: Alain Charcosset

AMAIZING will involve 24 partners, public research institute and breeding compagnies with diverse complementary expertise over duration of 8 years.

For complete list, see:

Bioinformatics (Workpackage 2) : 3 partners : UMR Génétique Quantitativ Evolution - Le Moulon - (leader), URGI, BGA)

AMAIZING will produce and manipulate very large bodies of heterogeneous data including million of sequence reads (WP3), genotyping (WP4) and phenotyping data points (WP5).

These data will have to be conveniently stored, pre-processed and made available to the partners of the project and to the international community.

One main goal of WP2 is to provide partners bioinformatics and Information Technology (IT) expertise, hardware services, scientific programming, database management, scientific software and database training.

The project Information System will be based on a set of distributed and existing databases : GnpIS, ThaliaDB and an analysis tool Biomercator, that will be improved to take into account Amaizing User needs.
