Fig. 1 Disease resistance of rice by overexpression of WRKY45 (A and B) Disease resistance of WRKY45-ox rice to fungal blast (A) and bacterial blight (B) diseases. (C) WRKY45-ox rice is even more blast resistant than the highly blast resistant rice variety ‘Sensho’. |
Fig. 2 SA signalling pathways in Arabidopsis and rice In Arabidopsis, downstream of SA is largely controlled by NPR1. In rice, the SA pathway separate into WRKY45- and OsNPR1-dependent pathways. An environmental factor (s) acts downstream of WRKY45 and OsNPR1 to trigger defence-gene expression. |
Fig. 3 Growth and PR-gene expression in WRKY45-ox rice plants under different growth conditions Greenhouse-grown WRKY45-ox rice showed only minor growth retardation, whereas, it was much more severe in growth-chamber-grown WRKY45-ox rice. Expression of PR1b and PR1a, as markers of defence reactions, was undetectable in greenhouse-grown but highly detected in growth-chamber-grown WRKY45-ox rice. |
