Other claims from this paper (13)
- Observation Azoarcus colonization was associated with 523 differentially expressed genes in rice roots.
- Observation Only 6% of the differentially expressed genes overlapped between Azoarcus and Xoo colonization in rice roots.
- Intervention effect Xoo infection induced a stronger defense reaction in rice roots than Azoarcus colonization.
- Observation Azoarcus colonization led to down-regulation of many defence related rice root genes.
- Observation Endophyte-induced rice root DEGs encoded enzymes for phytoalexin biosynthesis, ROS production or PR proteins.
- Observation The Azoarcus-induced signal transduction marker DEGs did not overlap with published DEGs of the rice endophyte Azospirillum sp. B510.
- Observation The authors suggest a large variation in rice responses among individual genotypic combinations.
- Observation DEGs related to the jasmonate signalling pathway were consistently activated by both beneficial endophytes in rice roots.
- Observation The salicylate pathway in rice roots was activated only in roots infected by the pathogen.
- Intervention effect In the cpm2 jasmonate-deficient rice mutant, endophytic colonization by Azoarcus was significantly increased compared with the other lines.
- Intervention effect In the cpm2 jasmonate-deficient rice mutant, Xoo colonization was not affected.
- Intervention effect NPR1 knockdown rice lines showed slightly decreased colonization by Xoo.
- Mechanism The authors conclude that JA but not SA signalling controls endophyte density in rice roots and can restrict internal root colonization.
