Abstract
Many R genes have been cloned and functionally validated.This has contributed to our understanding of R gene mechanisms while providing effective resistance. Pangenomes provide the most accurate representation of a species genome by incorporating genetic diversity from a range of individuals.The number of pangenomes for vegetable crops is growing. Developments in resistance gene enrichment sequencing (RenSeq), such as SMRT RenSeq, have facilitated the rapid identification of causal R genes, as well as characterising the species-wide repertoires of R genes. -omics technologies have provided some insights into the complex mechanisms of quantitative resistance (QR). Alternative biotechnologies, such as ncRNA, can be used to enhance disease resistance.
