Other claims from this paper (9)
- Method / resource Selection produced the ANOM1 BC1F5 germplasm for race G resistance and cultivated sunflower resemblance.
- Observation The resistance trait showed monogenic dominant inheritance.
- Observation Or Anom1 mapped to a 1.2 cM Chromosome 4 interval and co-segregated with seven SNP markers.
- Observation The target interval corresponds to a 1.32 Mb sunflower reference region with RLK-RLP genes.
- Observation The H. anomalus target region lacked RLPs.
- Observation Two RLKs in the H. anomalus region were proposed as Or Anom1 candidates.
- Observation Broomrape established a vascular connection with the sunflower host.
- Observation Broomrape growth stopped before tubercle development in resistant sunflower.
- Observation Resistance involved phenolic compound accumulation and tubercle necrosis.
