Abstract
Potato (Solanum tuberosum) is the third most important food crop worldwide, providing a significant source of nutrition and livelihood. To better understand the complex biological processes and improve potato breeding and cultivation strategies, various -omics techniques have been employed. Genomics, transcriptomics, proteomics, and metabolomics have been extensively used to unravel the potato genome structure and function, find gene expression patterns, determine protein abundance, and pinpoint metabolic pathways. These -omics approaches have contributed to the identification of key genes, molecular markers, and metabolic pathways associated with important traits such as disease resistance, yield, quality, and environmental adaptation. Linked to potato phenotyping, which remains a bottleneck, -omics techniques can help to understand the gene x environment x management interaction, which is key for breeding and precision agriculture. In this overview, we highlight the significance and recent advances of -omics techniques related to potato biology and their potential application in potato breeding and crop management. We find that during the last 5 years, a little over half of the transcriptome studies have concerned abiotic stress, whereas the largest part of the biotic studies concerns interactions with Phytophthora infestans. The last couple of years have also seen an explosion in the increase of available potato cultivated and wild genome assemblies. Cross-omics and holistic studies are, however, still quite scarce with a large potential of future developments, particularly when it comes to moving from greenhouse experiments to the fields. We highlight possibilities and current gaps in potato -omics and systems biology.
