Khairul Ansari; Siamsa Doyle; Joanna Kacprzyk; et al. Toxins 2014. doi:10.3390/toxins6020679

Other claims from this paper (10)

Intervention effect DON at 10 μg mL(-1) does not cause cell death in Arabidopsis cell cultures.
Association DON's ability to retard heat-induced cell death in Arabidopsis cell cultures depends on light.
Intervention effect Under darkness, DON promotes heat-induced cell death in Arabidopsis cell cultures.
Intervention effect No evidence was found that light affects defense-gene transcription in DON-treated roots of CM82036 seedlings.
Intervention effect No evidence was found that light affects defense-gene transcription in DON-treated roots of Remus seedlings.
Intervention effect Root DON treatment produces genotype-dependent, light-enhanced defense transcript accumulation in wheat coleoptiles.
Intervention effect DON upregulates PAL, NPR1 and POX transcripts in CM82036 coleoptiles.
Intervention effect DON does not upregulate PAL, NPR1 and POX transcripts in Remus coleoptiles.
