Other claims from this paper (14)
- Observation Rhizophagus irregularis colonized Citrus aurantium roots abundantly three weeks after inoculation.
- Intervention effect Mycorrhized C. aurantium showed reduced leaf damage by Tetranychus urticae compared with non-mycorrhized controls.
- Intervention effect Mycorrhization did not affect host choice of mites in Y-tube assays.
- Observation Citrus aurantium has innate strong antixenotic resistance against Tetranychus urticae.
- Intervention effect Mycorrhization increased jasmonic acid, OPDA and JA-Ile concentrations in citrus.
- Intervention effect Mycorrhized citrus plants upregulated LOX-2 and PR-3 expression early after infestation.
- Observation Non-targeted metabolomics showed amino acid, oxocarboxylic acid and phenylpropanoid metabolism as the three major pathways with more hits at 24 hpi in mycorrhized plants.
- Observation Mycorrhized citrus showed a transition to a priming profile of these pathways at 48 hpi after infestation.
- Observation Malic acid, coumaric acid and diconiferyl alcohol were among the priming compounds.
- Intervention effect A mixture of all these compounds provided efficient protection against the mite.
- Observation Systemic resistance did not improve after 72 h of primary infestation in citrus.
- Mechanism The lack of improved systemic resistance is probably due to the innate strong systemic resistance of C. aurantium.
- Observation Mycorrhiza-induced resistance is functional against Tetranychus urticae in locally infested citrus leaves.
- Mechanism MIR is likely mediated by a complex pool of secondary metabolites and coordinated by priming of JA-dependent responses.
