Title

Effects of Ultraviolet-B Radiation on the Regulation of Ascorbic Acid Accumulation and Metabolism in Lettuce

Shujuan Liu; Lei Yu; Lipan Liu; et al. Horticulturae 2023. doi:10.3390/horticulturae9020200

Other claims from this paper (9)

Intervention effect Photosynthetic gas exchange measures fell during the first four irradiation days and recovered at day seven.
Intervention effect UV-B increased lettuce AsA, GSH and H2O2 levels significantly.
Association H2O2 level correlated positively with AsA and GSH levels.
Intervention effect UV-B upregulated expression of most genes encoding AsA recycling enzymes.
Intervention effect UV-B downregulated associated AsA recycling enzyme activities.
Mechanism The authors propose that elevated AsA contributes to the AsA–GSH cycle and downregulates AO activity and expression.
Observation UV-B irradiation affected metabolite levels more than treatment time.
Mechanism The authors suggest feedback between AsA recycling enzyme expression and activity regulates AsA homeostasis.
Recommendation The authors recommend short-term UV-B supplementation to enhance lettuce AsA content.
