Towards more sustainable resistances to downy mildew in sunflower

Downy mildew is a sunflower disease that can lead to an almost total loss of yield in the case of serious attacks. Thanks to long work on valorization of natural genomic resources and to the development of new genotyping technologies, scientists and technicians at the plant-microorganisms interactions laboratory (LIPM) have improved understanding of infection mechanisms which should help to reinforce disease resistance of sunflower in the field.

Genetic resources of wild and cultivated sunflowers

As a public research institute, INRA explores and preserves biodiversity and genetic resources of several crops. These resources are available to public and private collaborators according to national policies and international agreements. In order to maintain a wide genetic diversity for research and breeding, the Biological Resources Centre (BRC) for sunflower develops its collection since the 1960s and is now operating at INRA Occitanie-Toulouse.

Sunflower genome reveals symphony of genes involved in oil production and flowering

Less than one year after the decoding of the sunflower genome, in-depth analyses of said genome have revealed the hundreds of genes that work together to regulate flowering, and those that are involved in the production of oil. Carried out by INRA scientists¹ within the framework of the SUNRISE project in the French Investments for the Future Programme and in collaboration with the International sunflower genome consortium², the studies were published online in the May 22, 2017 issue of Nature.

A major advance in characterising downy mildew resistance genes in sunflower

A team of INRA scientists from Toulouse and Clermont Ferrand has developed a method that can identify the proteins responsible for the virulence of the parasite that causes downy mildew in sunflower. This disease can cause an almost total loss of yield in the event of a severe infestation. These findings have just been published in the journal Frontiers in Plant Science. This advance should facilitate the characterisation of genes for the resistance of sunflower to downy mildew.

A look back at 10 years of research on sunflowers: Toulouse, the “Sun Valley” of sunflowers?

Close to 130 scientists, seed companies, sector professionals, farmers, and industrial players gathered in Toulouse on 28 and 29 June to discuss the findings and perspectives of research on sunflowers. The event proved that sunflowers are a fine model for putting partners in touch and allowing different disciplines to see common ground.
