Table 3 Summary of total AQPs currently identified within Solanaceae. Tomato and potato AQP families were characterised by Reuscher et al. (2013) and Venkatesh et al. (2013), respectively. N.sylvestris, N.tomentosiformis and tobacco gene families were established in this study. Numbers indicate genes occurring in each AQP sub-family (PIP, TIP, NIP, SIP and XIP). The number of identified N.tomentosiformis PIPs through the BLAST searches was 15 (noted by superscript value), however, we predict the total number of PIPs at the time of hybridisation to be 16 due to NtPIP2;1x likely being of N.tomentosiformis origin. This brings the overall number of N.tomentosiformis AQPs to 42
