Biography of Vitis genomics: recent advances and prospective

Abstract

Abstract Grape genome is the basis for grape studies and breeding, which is also important for grape industries. In the last two decades, more than 44 grape genomes have been sequenced. Based on these genomes, researchers have made a substantial progress in the mechanism of biotic and abiotic resistance, berry quality formation, and breeding strategies. In addition, these works provide essential data for future pan-genome analysis. Apart from the de novo assembled genomes, more than six whole-genome sequencing projects have provided datasets comprising almost 5000 accessions. Based on these datasets, researchers explored domestications and origin of grape and clarified the gene flow that occurred during the dispersed history. Moreover, GWAS and other methods were used to identify more than 900 genes related to the resistance, quality, and developmental phases of grape. These findings have benefit grape studies and provide some basis for smart genomic selection breeding. Otherwise, the grape genome has played a great role in grape studies and industries, and the importance of genomics will increase sharply in the future.
