A systems biology approach to study the genetic variability of proteome responses to water deficit in sunflower

Résumé

Climate change is a current issue of major concern because of its potential effects on biodiversity and the agricultural sector. Better understanding the adaptation of plants to this recent phenomenon is therefore a major interest for crop science and society. The domesticated sunflower, Helianthus annuus L., is the fourth most important oilseed crop in the world and has promise for agriculture adaptation because it can maintain stable yields across a wide variety of environmental conditions, especially during drought stress. As drought stress response involves a large number of molecular pathways and subsequent physiological processes, it constitutes an archetypical systems biology model. Here, we studied the responses of eight parental lines (four males and four females) and their 16 hybrids cultivating with the outdoors high-throughput automated phenotyping platform Heliaphen. Multi-omics analyses combining transcriptomics, metabolomics, proteomics and ecophysiological data were carried out in order to perform an integrative study. Statistical modelling of relationships between these datasets aimed at establishing the molecular players of drought stress response with the integration of some genetic diversity and heterotic behaviours.
