Title
Mannitol biosynthesis is required for plant pathogenicity byAlternaria alternata

Other claims from this paper (8)
- Observation All fungal mutants produced viable conidia that germinated normally.
- Observation Trehalose levels were elevated in the fungal mutants.
- Intervention effect The MtDH mutant did not reduce tobacco lesion severity versus wild type.
- Intervention effect The MPDH mutant caused significantly less disease.
- Intervention effect The double mutant caused significantly less disease.
- Observation The double mutant still germinated and formed appressoria on tobacco leaves.
- Observation The double mutant elicited a host defense response.
- Mechanism The authors conclude mannitol biosynthesis is not required for spore germination or initial infection.
