Title

Resistance of pea roots to endomycorrhizal fungus or Rhizobium correlates with enhanced levels of endogenous salicylic acid

Other claims from this paper (6)

Observation Glomus mosseae induced SA accumulation in wild type and P2 pea roots.
Association The induced SA accumulation was greater in P2 plants and rose with time, unlike wild type.
Association SA accumulation in P2 plants increased with time.
Observation Rhizobium leguminosarum wild type induced SA accumulation in P2 pea roots.
Association Wild type pea root SA accumulation depended on bacterial inability to make Nod factors.
Mechanism The authors suggest sym30 suppresses SA dependent defence against Rhizobium and endomycorrhizal fungi, allowing symbiosis.
