Early transcriptional regulation of cell wall remodeling and defense responses underlies grapevine bunch compactness
The understanding of the bunch compactness (BC) genetics in Vitis vinifera L. has greatly benefited from the availability of sensor-based data, which has allowed us to elucidate which of the multiple subtraits determining this complex attribute are the major contributors to the overall phenotype and which genetic variants are the ones associated with it. However, expression data for these candidate genes are still lacking, and obtaining such data could contribute to a better understanding of the middle ground where genetics translates into the final phenotype.
