Tracking Papaya Pollen Movement with the GUS Transgene Marker

Tracking Papaya Pollen Movement with the GUS Transgene Marker - Acta Horticulturae, 740, p.183-191, 2007 .

Transgenic, virus-resistant papaya cultivars in Hawaii are easily identified by a colorimetric assay for the beta-glucuronidase (GUS)marker transgene. We used GUS to track pollen movement from a central 0.5-ha plot of gynodioecious transgenic 'Rainbow' plants by seed assays on plants in surrounding border rows of non-transgenic 'Sunrise' papaya. GUS evidence of cross-pollination occurred in 70
