Article Title: Rhizobacteria prime the activation of defence and nutritional responses to suppress aphid populations on barley
doi: 10.1101/2024.09.04.611222
Figure Lengend Snippet: This bubble plot showed the enriched KEGG pathways of upregulated and downregulated differentially expressed genes in leaves of barley without treatment (Control), infested with the aphid Sitobion avenae (Sa), inoculated with the rhizobacteria Acidovorax radicis (Ar) or Bacillus subtilis (Bs) , or inoculated with rhizobacteria and infested with aphid (ArSa or BsSa) . In Sa , ArSa and BsSa plants, the aphid S. avenae was allowed to feed on plants for 24 hours, 7 and 21 days. (a) shows genes induced by Sa relative to Control . (b) shows treatment groups inoculated with Ar : Ar vs. Control are genes altered by Ar in absence of aphids. ArSa vs. Control are genes induced by both rhizobacteria and aphids relative to Control . ArSa vs. Ar shows the aphid (Sa) induced genes in rhizobacteria (Ar) inoculated plants. ArSa vs. Sa shows the rhizobacteria (Ar) induced genes in aphid (Sa) infested plants. (c) shows treatment groups inoculated with Bs : Bs vs. Control are genes altered by Bs in absence of aphid. BsSa vs. Control are genes induced by both rhizobacteria (Bs) and aphid (Sa) relative to Control . BsSa vs. Bs shows the aphid (Sa) induced genes in rhizobacteria (Bs) inoculated plants. BsSa vs. Sa shows the rhizobacteria (Bs) induced genes in aphid (Sa) infested plants.
Article Snippet: Acidovorax radicis was cultivated at 30 °C on nutrient agar plates (Difco™ General purpose nutrient broth 8 g/litre plus 15 g -agar) and grown for 96 hours.
