Genomic variation between PRSV resistant transgenic SunUp and its progenitor cultivar Sunset.

ABSTRACT:

Background

The safety of genetically transformed plants remains a subject of scrutiny. Genomic variants in PRSV resistant transgenic papaya will provide evidence to rationally address such concerns.

Results

In this study, a total of more than 74 million Illumina reads for progenitor 'Sunset' were mapped onto transgenic papaya 'SunUp' reference genome. 310,364 single nucleotide polymorphisms (SNPs) and 34,071 small Inserts/deletions (InDels) were detected between 'Sunset' and 'SunUp'. Those variations have an uneven distribution across nine chromosomes in papaya. Only 0.27% of mutations were predicted to be high-impact mutations. ATP-related categories were highly enriched among these high-impact genes. The SNP mutation rate was about 8.4 × 10^- 4 per site, comparab
