Adaptation to a changing climate and the genetic basis of flowering time variation in pearl millet – CLIM

Submission summary

CLIM : Adaptation to a changing climate and the genetic basis of flowering time variation in pearl millet Sahelian countries have experienced a significant shift to drier climates in the last 40 years, and one of the major cereal crops in these countries is pearl millet. One of the most important adaptations of plants to shorter rainy seasons is flowering time. In the context of a changing climate, earlier flowering in pearl millet may mitigate the effects of climatic change by allowing flowering and seed production in drier environments than those of 40 years ago. The aim of this project is to identify genes responsible for the adaptations of pearl millet to climate variation. Our main hypothesis is that the flowering pathway is relatively conserved across species, which makes knowledge of flowering time gene from model plants relevant to the study of flowering time differences in neglected species. Our methodology uses an original approach combining both genome selection scans and association studies in an understudied crop. Genome selection scan methods allow the screening of a large number of loci from model plant species. We will develop a new methodological framework to allow this method to be more widely applicable. The role of each gene will then be validated by the association of genotypic variation with flowering phenotype. The study will be of value to pearl millet breeders and allow them to develop improved varieties adapted to different precipitation conditions. It is unique in that it will permit the assessment of adaptation to changing climate at the molecular level.
