Project description:Kumquat (Fortunella classifolia Swingle) was thought as a close relative to citrus according to fruit morphology taxonomic, but kumquat fruit as well as its flowering characteristic are distinct from other citrus species, the trees usually blooms on the medium of June, obviously later than other citrus species, moreover many kumquat accessions could be blossom more than one times during one growth season, as this reason, the kumquat fruits could be consecutively ripen over several months, which made the study of globe genes expression profile for different development stage fruit easy. Kumquat is non-climacteric fruit, however the kumquat fruit ripening process, especially genes expression change in young and ripe kumquat fruits are less known, so studying on the global genes expression profiles of kumquat fruits in young and ripe stage are especially helpful to identify ripening-related genes and unravel the mechanism of ripening process.
