Interpretive Summary:

Technical Abstract: The genome of papaya (372 Mbp) is at least 10% smaller than that of rice, the only completely sequenced crop plant to date. The small genome size of papaya and the fact that it can produce fruit in as few as 9 months make it a potential model organism for fruit-producing tree crops. An added incentive to analyzing this particular plant genome is provided by the recent identification of a primitive sex chromosome in papaya, which has commercial implications, as hermaphrodites have preferred agronomic characteristics. Here we report the analysis of 50,661 BAC end sequences from a papaya BAC library constructed by Ming et al. (2001), which provides a first glimpse into the sequence composition of the papaya genome. The annotated BAC-end sequences will serve as useful resources for physical mapping, positional cloning, genetic marker development and genome sequencing of papaya.
