1. Introduction
Papaya, Carica papaya L. is an important tropical fruit crop. Ripe fruits are consumed fresh while unripened fruits can be used in salads or as a vegetable and as a source of papain. Papaya fruits are a rich source of vitamins and minerals, low in sodium, fat and calories, and lack starch (Hewajulige and Dhekney, 2016). Papain, a proteolytic enzyme obtained from immature fruits is used in the pharmaceuticals, leather, wool and rayon industries (Seelig, 1970). Papaya is grown on 0.43 million ha with an annual production of 11 million tons. A majority of the production occurs in Asia and the Americas (FAOSTAT, 2013). Papaya (2n¼2x¼18) is a member of the Caricaceae family, which consists of herbaceous plants (Badillo, 1993). The crop is believed to have originated in Central America in regions ranging from Mexico to Panama. The Caricaceae was originally comprised of 31 species in the Carica, Jacartia and Jarilla genera from Central America and the African Cylicomorpha genus (Nakasone and Paull, 1998). Taxonomic revisions resulted in some species being transferred from Carica to the Vasconcella genus (Badillo et al., 2000). Consequently, the Vasconcella genus now consists of 21 species followed by Jacartia with 7 species, while papaya is now the sole species in the Carica genus (Badillo, 1993). Major goals of papaya improvement programs include increased yield and productivity, resistance to biotic and abiotic stress factors and improved quality characteristics. Papaya cultivars with improved traits such as high yield and quality have been successfully developed through intensive breeding programs worldwide (Chan, 2002; Nakasone and Paull, 1998). Minisatellite and microsatellite markers have been explored to accelerate papaya genetic improvement, analyze phenotypic variation for traits of interest, and understand genetic relationships for efficient management and conservation of genetic resources (Oliveria et al., 2010; 2015a, 2015b). Papaya improvement for stress tolerance (abiotic and biotic) via hybridization with species from other genera of the Caricaceae family has been marginally successful. Limitations for transfer of useful traits are attributed to several post-zygotic incongruities including embryo abortion, poor seed viability and sterility in progeny obtained following hybridization between two genera (Horovitz and Jimenez, 1967; Manshardt and Wenslaff, 1989). The limitations encountered in papaya improvement via conventional breeding can be overcome by biotechnological approaches such as embryo rescue and genetic engineering. Genetic engineering of papaya allows incorporation of specific traits into elite cultivars without potentially altering the existing phenotype. The process involves transfer of specific DNA sequences in cell cultures and their subsequent integration into the host genome. The prerequisites for successful gene transfer include efficient cell culture systems for plant regeneration and gene insertion techniques (Birch, 1997). Recent advances in papaya genomics along with refinement of cell culture and gene insertion protocols make genetic engineering as an important tool for studying gene function and expression in papaya and the development of improved cultivars. This chapter will review the progress in papaya cell culture, genetic engineering and genomics, and the successful application of this technology for papaya improvement.
