Other claims from this paper (8)
- Observation GR18-1 resisted powdery mildew at seedling and adult stages.
- Observation PmGR-18 mapped to the Pm4 interval on chromosome arm 2AL.
- Observation Xwgrc763 and Xwgrc872 flank PmGR-18 at 0.5 and 1.0 cM, defining a 1.13 Mb interval.
- Observation PmGR-18 sequence matched Pm4d exactly.
- Intervention effect After Bgt E09 inoculation, Pm4d_V1 expression rose significantly.
- Intervention effect After Bgt E09 inoculation, Pm4d_V2 expression rose significantly.
- Observation Pm4d_V2 expression was significantly lower than Pm4d_V1 at most time points.
- Method / resource Flanking and functional markers enabled tracking PmGR-18 into susceptible cultivars.
