Other claims from this paper (13)
- Observation A targeted search identified (R)-β-tyrosine in Nipponbare seeds, leaves, roots, and root exudates.
- Observation β-tyrosine presence varied among 119 cultivars.
- Association β-tyrosine was most prevalent in temperate japonica cultivars.
- Observation Mapping identified a candidate β-tyrosine gene on chromosome 12.
- Intervention effect A point mutation in TAM1 eliminated β-tyrosine production in Nipponbare.
- Association Rice cultivars lacking β-tyrosine production have a chromosome 12 deletion encompassing TAM1.
- Intervention effect Jasmonic acid induced β-tyrosine accumulation.
- Intervention effect β-tyrosine had no negative effects on hemipteran herbivores at physiologically relevant concentrations.
- Intervention effect β-tyrosine had no negative effects on lepidopteran herbivores at physiologically relevant concentrations.
- Intervention effect β-tyrosine inhibited Arabidopsis thaliana root growth at concentrations as low as 1 μM.
- Intervention effect β-tyrosine inhibited root growth of other tested dicot plants at concentrations as low as 1 μM.
- Observation Rice exudes β-tyrosine into hydroponic medium at higher concentrations.
- Mechanism Authors suggest that exuded β-tyrosine may contribute to rice allelopathy.
