Abstract
In the early 1990s an outbreak of papaya ringspot virus (PRSV) in the papaya groves in the Puna district of Hawaii caused severe damage to an important crop. Since then, the planting of two transgenic cultivars resistant to the virus — called 'SunUp' and 'Rainbow' — has helped to maintain yields. SunUp is a transgenic red-fleshed fruit that expresses the coat protein gene of a mild mutant of PRSV, conferring resistance via post-transcriptional gene silencing. Rainbow is a yellow-fleshed (and therefore more popular) F1 hybrid bred from SunUp. Now the draft genome sequence of the SunUp strain of papaya has been determined — a first for a commercial virus-resistant transgenic fruit tree. Comparison of this plant…
