Project description
It is widely accepted that the changing climate could have profound impacts on agriculture. The proposed study will use state-of-the art technologies to study and interpret the impacts of changing environmental factors on grapevine biology, organ development and berry quality in vineyards, following a grapevine ‘field-omics’ approach. Ultimately the proposed work will provide a understanding of how a grapevine functions in interaction with its complex and changing environment. The proposed project seeks to specifically interpret the impacts of changes to the physical environment of developing and ripening berries and the grapevine and environment interaction.

The aims are: Constructing a field-omics experimental workflow Modulating the microclimate of developing and ripening grapevine berries in a model vineyard and profiling of the transcriptomic and metabolic responses Developing a more integrated understanding of grape berry ripening
