e0“The potentiated activation of cellular defense responses in AATP1(St) antisense tubers is not accompanied by a precedent increase in endogenous salicylic acid levels, but is associated with a strongly enhanced resistance of the tissue to E. carotovora”

Other claims from this paper (10)
- Intervention effect Decreased AATP1 activity in transgenic potato tubers reduced starch levels.
- Intervention effect Decreased AATP1 activity modified tuber morphology.
- Intervention effect Decreased AATP1 activity altered concentrations of primary metabolites in potato tubers.
- Intervention effect Hydrogen peroxide production, salicylic acid content and defense-gene mRNA levels in tuber discs were similar between wild-type and AATP1(St) antisense plants.
- Intervention effect AATP1(St) antisense tubers showed highly potentiated activation of defense responses compared with wild-type tissue after challenge with fungal elicitors or Erwinia culture supernatants.
- Intervention effect AATP1(St) antisense tubers accumulated more transcripts of beta-1,3-GLUCANASE B2 and A1.
- Intervention effect AATP1(St) antisense tubers accumulated more transcripts of CHITINASE B3 and A2, and Phe AMMONIA-LYASE.
- Intervention effect Elicitation of the early hydrogen peroxide burst was enhanced up to 21-fold in AATP1(St) antisense tubers.
- Intervention effect AATP1(St) antisense tubers had a strongly enhanced resistance to E. carotovora.
- Mechanism The authors conclude that inhibition of primary metabolic reactions primes potato tubers for improved defense elicitation, which likely contributes to enhanced E. carotovora resistance.
