Disease reactions of Pi-ta/Pi-ta2/Ptr differential lines. a Disease reactions of Pi-ta/Pi-ta2/Ptr lines to four diverse races/isolates. Disease reaction was evaluated 7 days post-inoculation with 0–5 rating scale where 0–2 is resistant and 3 to 5 is susceptible. Rice varieties with the Pi-ta/Pi-ta2/Ptr genes were susceptible to IE-1K (TM2 lacking AVR-Pita) and resistant or moderately resistant to the transformant IE-1K + AVR-Pita from O-13715. Note: M. oryzae races (isolates), IB-1 (15A6_3, 15L22_3), IB-17 (SSID116), IB-49 (ML1), and IE-1 (14A15–2), differentiated the Pi-ta-containing rice lines from the rice lines with Pi-ta2/Ptr. b Photographs showing disease reaction of indicated rice lines and races: Katy (Pi-ta+/Pi-ta2+/Ptr+), Amane (Pi-ta+/Pi-ta2?/Ptr-) and M2354 (Pi-ta+/Pi-ta2-/Ptr−), and S/C272 (Pi-ta−/Pi-ta2?/Ptr+). Pictures were taken at seven days post-inoculation
