Abstract

Wheat powdery mildew is one of the most destructive diseases threatening global wheat production. The wild relatives of wheat comprise rich sources of diversity for powdery mildew resistance. Here, we report map-based cloning of broad-spectrum powdery mildew resistance gene Pm13 from wild wheat species Aegilops longissima. Pm13 encodes a novel mixed lineage kinase domain-like (MLKL) protein which contains an N-terminal HeLo domain and a C-terminal authentic serine/threonine kinase (STK) domain, a unique domain architecture that has not been reported in plant disease-resistance genes. The resistance function of Pm13 was validated by loss-of-function mutants, gene silencing, transgenic assay, and allelic association analyses. Thus, Pm13 represents a special class of plant resistance genes revealing a novel aspect of host-pathogen interactions. Though introgressed into wheat ~30 years ago it was hardly exploited due to linkage drag. The new lines with small Ae. longissima Pm13 segment will lead to wide-scale deployment in wheat cultivars.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
