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.

Xin He; Jinghong Hao; Shuangxi Fan; et al. Plants 2022. doi:10.3390/plants11101385

Other claims from this paper (11)

Intervention effect Heat stress decreased lettuce seedling total fresh weight by 33%.
Intervention effect Heat stress inhibited photosynthesis, more strongly under D-arginine treatment.
Intervention effect Spermidine recovery increased net photosynthetic rate, stomatal conductance and transpiration rate.
Intervention effect Spermidine recovery increased stomatal limit value and intercellular CO2 concentration.
Intervention effect Heat stress reduced Fv/Fm, qP and ETR.
Intervention effect Heat stress reduced PSII photochemical efficiency.
Intervention effect Heat stress increased NPQ.
Intervention effect Heat stress reduced light energy use, and exogenous spermidine alleviated that response.
Mechanism The authors propose increased polyamine content may stem from increased synthase and decreased oxidase activity.
Mechanism D-arginine suppressed endogenous polyamine levels and reduced lettuce heat tolerance.
Mechanism Exogenous spermidine promoted polyamine accumulation and increased lettuce photosynthetic and oxidative stress levels.

Title

Spent coffee grounds as an alternative fertilizer: impact on bioaccessibility of antioxidants and commercial quality of lettuce

Mariela Patrignani; Héctor Joaquín Hasperué; Ana Cervera‐Mata; et al. Journal of the Science of Food and Agriculture 2024. doi:10.1002/jsfa.13936

Other claims from this paper (8)

Intervention effect High spent coffee ground concentrations made lettuce tissues lighter and less green.
Intervention effect High spent coffee ground concentrations reduced lettuce root development.
Intervention effect Spent coffee ground levels affected antioxidant release.
Intervention effect In digested lettuce, increasing spent coffee grounds from 10 to 125 g kg −1 increased FRAP antioxidant amount from 43.88 ± 4.81 to 105.96 ± 29.09 μmol Trolox g −1 dry weight.
Intervention effect The IC RED assay found the highest antioxidant value at 150 g kg −1 spent coffee grounds.
Intervention effect Low spent coffee ground levels significantly increased antioxidant release in the fermented fraction.
Intervention effect Intermediate spent coffee ground amounts produced the highest insoluble antioxidant amount.
Recommendation The authors recommend balancing antioxidant capacity with visual quality.
