The impact of global warming on bud dormancy in temperate fruit trees. An approach in sweet cherry

Abstract : Bud dormancy is the mechanism that temperate fruit trees use to synchronize their phenology with unfavourable climatic conditions. In a swiftly-changing environment, temperate fruit crop adaptation in many areas will be at risk in the coming decades. Problems associated to bud dormancy related issues may be wide-ranging: flowering, fruit set, sun-scald, spring frost, cross-pollination or host-pest interaction. A model for bud dormancy control in temperate fruit trees is proposed. We present a research approach integrating genomics, phenomics and modelling in a non-model, but highly appreciated, fruit species: sweet cherry. Phenomics resources include phenology data from INRA’s wide germplasm collection (>400 accessions), phenology data from all over Europe and overseas (supported by the COST action on sweet cherry that INRA-Bordeaux is leading), and chilling requirements data of a mapping population (3 years). Genomics resources developed include sweet cherry unigene and RNAseq, which are been used as tools for candidate gene research within different pathways related to bud dormancy. qRT-PCR analysis are on-going for validation. In addition, mapping progenies and collection were genotyped using the 6K SNP chip developed within the RosBREED project. Association genetics and QTL analyses are underway, while GWAS is also envisaged. The final objective is the integration of phenotypic, genomic and climatic data that will be modelled to predict the phenotype of a particular genotype in a predetermined climatic condition.
