Other claims from this paper (11)
- Intervention effect TuMV infection reduced stomatal aperture in Arabidopsis.
- Intervention effect TuMV infection diminished gas exchange rate, daily water consumption and rosette initial dehydration rate in Arabidopsis.
- Intervention effect TuMV-infected Arabidopsis overaccumulated salicylic acid and abscisic acid.
- Intervention effect TuMV infection altered expression levels of key ABA homeostasis genes in Arabidopsis.
- Intervention effect TuMV infection induced expression of the ABA signalling gene ABI2.
- Intervention effect TuMV infection highly induced expression of ABCG40 in Arabidopsis.
- Intervention effect The abi2-1 mutant abolished both TuMV-induced stomatal closure and low stomatal conductance.
- Intervention effect ABA or SA biosynthetic, signalling or degradation mutants other than abi2-1 did not abolish the TuMV-induced stomatal phenotypes.
- Intervention effect TuMV infection lowered relative water loss in Arabidopsis.
- Intervention effect Plants under combined drought and viral stress had higher mortality than mock-inoculated drought-stressed controls.
- Intervention effect TuMV infection diminishes drought tolerance in Arabidopsis, despite the stomatal closure it triggers.
