Future perspectives and challenges Completion of the A. chinensis WGS will be the first within the Ericales a large and diverse order that includes persimmon blueberry cranberry and tea and the benefits to be gained in having the Actinidia WGS are enormous. Genome annotation is a key to the utility of any WGS and the advances in transcriptome sequencing will greatly aid the defining and delineating of genes. Building on the availability of the genome sequence characterization of the interrelationships between the Actinidia genome transcriptome proteome and metabolome and functional genomics of alleles will greatly aid in the understanding of biological processes phenotypes and traits of kiwifruit. The annotated A. chinensis WGS will also provide a reference genome for the sequencing of genomes of other Actinidia species to examine inter-species variability and to identify SNPs. The knowledge gained from these efforts will open up greater opportunities for molecular breeding in kiwifruit allowing the use of molecular markers for selective and accelerated introgression of desirable traits from the diverse Actinidia germplasm to create new and novel cultivars. As detailed in this chapter much of the molecular research in Actinidia has targeted traits such as fruit flavour aroma ripening and colour which could be exploited in the development of new cultivars with novel fruit characteristics. There has been very little molecular research in Actinidia targeted towards pathogens and disease. However the recent devastating effect on commercial kiwifruit orchards in parts of Italy due to kiwifruit canker caused by the bacterium Pseudomonas syringae pv. actinidiae Psa may well change the emphasis of the immediate future of kiwifruit research. Although Psa was identified in Italy in 1992 Scortichini 1994 the bacterium caused little problem until severe disease outbreaks in both A. deliciosa and A. chinensis cultivars
