Abstract
Papaya Carica papaya L. cv. Eksotika and carambola Averrhoa carambola cv. B1O served as interesting tropical fruit softening models representing fast and slow-softening fruits respectively. This review however will focus specifically on papaya to describe the biochemical and molecular events that epitomized fruit softening during ripening. Major events that characterize papaya fruit ripening are the climacteric ethylene production the sequential disassembly of cell wall pectins and hemicelluloses and the functional significance of important wall enzymes notably -galactosidases and polygalacturonases in modifying the cell wall. A number of genes or gene products that are involved in ethylene biosynthesis and perception as well as in fruit softening have been isolated and characterized. These genes or gene products seem to be differentially expressed or accumulated through fruit ripening and maturation. The relevance of these findings to efforts to genetically modify papaya fruit ripening and softening will be discussed.
