Figure 2From: A change in temperature modulates defence to yellow (stripe) rust in wheat line UC1041 independently of resistance gene Yr36The effect of changes in temperature, up to eight days before inoculation with Pst, on yellow rust resistance in adult plants of the wheat line UC1041 - Yr36. A) Mean percentage (%) leaf area covered in uredia 18 dpi on adult plants inoculated with Pst isolate 08/21 kept at 12°C/18°C or 12°C/25°C pre and post inoculation (dark grey) or transferred to the other temperature regime post-inoculation (light grey). Mean values (± 1 standard error) were obtained from three independent experiments. Different letters indicate statistical significant differences (P < 0.01). B) Pst symptoms on flag leaves at 18 dpi in the four temperature regimes. Uredia can be observed within necrotic/chlorotic areas. C-D) Mean percentage (%) leaf area covered in uredia at 18 dpi on adult plants inoculated with Pst isolate 08/21 and kept at the original temperature regime of C) 12°C/18°C or D) 12°C/25°C pre and post inoculation (dark grey) or shifted at various time points before inoculation to the other temperature regime (light grey). Mean values (± 1 standard error) were obtained from four biological replicates. Different letters indicate statistically significant differences (P < 0.01).Back to article page
