PhD proposal: Genetic bases of adaptation in wheat wild relatives
Date de mise à jour : 3 juillet 2024
The objectives are:
- Identifying genes under selection in wheat wild relatives,
- Associating these selection footprints with environmental constraints,
- Identifying among those selected genes those that can be leveraged for wheat breeding.
Available data
The student will build up on already available whole transcriptome data (Glémin et al., 2019; Burgarella et al. 2023), which provides i) full transcriptome sequences for 103 individuals of 19 Triticeae species, ii) the level of expression of the different genes in these individuals, iii) polymorphism data (≥ 7 individuals for 5 species).
Additionally, high-quality whole genome sequences of wild, domesticated and modern wheat accessions are publicly available and large-scale sequencing projects are currently underway, as well as gene expression studies in domesticated wheat under stress. These data will be suitable for assessing the relevance of further investigating identified candidate genes in cultivated species.
