Other claims from this paper (9)
- Observation Three genes (CcOah, CcOdc1 and CcOdc2) directly involved in oxalic acid biosynthesis and catabolism were identified in C. chrysosperma.
- Observation CcOah is required for oxalic acid biogenesis in C. chrysosperma.
- Observation All three OA genes were highly upregulated during early infection stages of the poplar stem.
- Intervention effect Deletion of any of the three genes obviously reduced pycnidial production.
- Intervention effect Deletion of any of the three genes caused no abnormality of hyphal growth and morphology.
- Intervention effect Each individual deletion strain produced significantly smaller lesions on poplar twigs and leaves.
- Intervention effect The DeltaCcOah strain strongly promoted the reactive oxygen species burst of poplar leaves during infection.
- Observation Induced secretion of oxalic acid was observed after poplar stem extracts were added to C. chrysosperma cultures.
- Mechanism The results indicate that oxalic acid acts as an important virulence factor of C. chrysosperma.
