Figure 3From: A change in temperature modulates defence to yellow (stripe) rust in wheat line UC1041 independently of resistance gene Yr36The effect of changes in temperature on Pst development in seedlings of the wheat line UC1041 - Yr36. A) Mean leaf area (%) covered in uredia 18 dpi on UC1041 -Yr36 seedlings. Leaves were inoculated with Pst isolate 08/21 and kept at the original temperature regime of 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 up to 50 fields of view in three independent experiments. Different letters indicate statistically significant differences (P < 0.01). B-C) Microscopic characterisation of Pst development as categorised by the extent of hyphal colonisation. B) Illustration of Pst hyphal abundance, with each category of abundance being represented by different cross-hatching (upper panel). C) Frequency of occurrence of each category in each temperature treatment. Mean values for each category were obtained from three biological replicates.Back to article page
