Other claims from this paper (7)
- Intervention effect One week of red light at night did not significantly affect leaf biomass and area of tomato.
- Intervention effect Night red light altered leaf thickness and internode length in tomato, particularly in wild-type plants.
- Observation Transcriptomes differed significantly between wild-type and Nr plants, particularly in genes related to photosynthesis, growth regulation and the circadian clock.
- Intervention effect Red light modulated the expression of hormone-related genes in tomato leaves.
- Intervention effect Red light increased the activity of the antioxidant enzymes guaiacol peroxidase and glutathione S-transferase, in a manner dependent on ET in WT plants.
- Intervention effect Red light increased biotic stress resistance in Nr mutants, shown by reduced Botrytis cinerea infection.
- Mechanism The authors suggest red light may activate defence pathways independently of ET.
