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.

Observation Panda had dry weight per unit length of 2·35 mg/mm, among the strongest cultivars.
Observation Jennifer had dry weight per unit length of 2·34 mg/mm, among the strongest cultivars.
Observation Pipkin had dry weight per unit length of 1·75 mg/mm, the lowest among the cultivars.
Intervention effect Nitrogen application increased plant height.
Intervention effect Nitrogen application did not affect dry weight per main stem.
Intervention effect Nitrogen application decreased dry weight per unit length of stem.
Intervention effect The growth regulator treatments reduced plant height.
Intervention effect Dry weight per unit length of stem was similar in growth-regulator-treated and untreated plots.
