Yam (Dioscorea spp) is a tuberous crop extensively found in Eastern Africa and Asia constituting 6% of the world’s tuber production. It serves as a nutritional supplement with a high amount of protein (2.8%). A lot of medicinal relevance is also associated with the tubers. It is used as herbal medicine for the cure of diseases such as diabetes, aging, neurodegenerative diseases, and cancers. Dioscorin, the major protein of Dioscorea is a multi-functional enzyme possessing carbonic anhydrase (CA), dehydroascorbate reductase activity (DHAR), and monodehydroascorbate reductase activity (MDHAR). Despite of its wide utility the tuber remains an orphan crop as its genome and proteome have not been analyzed in detail. Efforts are under way to obtain the complete genome sequences to improvise yam molecular breeding. The availability of new genomic markers would help to identify duplicates accessions, to conduct diversity analysis and association mapping. The combination of proteomics and genomics, proteo-genomics would be useful for refining the genome annotation using the proteomics data. This chapter will review the advances made in understanding the tuber proteomics and outline the direction for future research.
