icsh1 mutants of V. dahliae were less virulent on potato than the wild-type strain; the gene is required for full virulence.

Other claims from this paper (7)
- Observation VdICSH1 expression was up-regulated in V. dahliae after induction with extracts from potato tissues.
- Observation VdICSH1 expression increased more in response to potato root extracts than to leaf and stem extracts.
- Observation VdICSH1 expression in response to root extracts did not differ significantly between the highly and weakly aggressive isolates tested.
- Observation During infection of detached potato leaves, VdICSH1 expression increased significantly in the highly aggressive isolate compared with the weakly aggressive one.
- Intervention effect Potato plants inoculated with the icsh1 mutant accumulated more bound SA than those inoculated with the wild-type strain.
- Association SA and JA accumulation in potato followed different trends in roots and stems at early infection stages versus leaves at later stages, indicating both are associated with potato defenses against V. dahliae.
- Observation Expression of isochorismatase family members in icsh1 mutants compensates for ICSH1 transcripts, but this compensation disappears in the presence of potato leaf extracts.
