Other claims from this paper (6)
- Intervention effect Aspergillus flavus biomass was significantly higher in the presence of mature and immature peanut kernels and hulls than in the control.
- Intervention effect Kernels and hulls lowered the expression of three Aspergillus flavus laccases by 4-6 fold.
- Intervention effect Three sucrose-induced Aspergillus flavus laccases were up-regulated 35-304 fold by 3% sucrose.
- Intervention effect Three Aspergillus flavus laccases were up-regulated 85-248 fold at low water potential.
- Observation Apparent degradation of phytoalexins was observed when phytoalexins were induced in seeds together with a priori induction of Aspergillus flavus laccases.
- Mechanism Up-regulation of Aspergillus flavus laccase expression at low water potential and high sucrose could contribute to peanut invasion of immature kernels under drought.
