Randomized trial investigates the effects of UV-A irradiation on secondary metabolite production in Artemisia argyi, highlighting its potential pharmaceutical uses.
Key Points
The aim is to explore the metabolic response of Artemisia argyi to UV-A irradiation and its effect on secondary metabolite production.
Investigated metabolic response through transcriptomic and metabolomic analyses after UV-A treatment for 16 hours followed by 8 hours of darkness.
Identified differentially expressed genes and metabolites in response to UV-A exposure over 6 days.
A total of 4343 differentially expressed genes were identified, primarily linked to fatty acid metabolism and secondary metabolite biosynthesis.
Out of 1959 detected metabolites, 223 were differentially accumulated, with phenolic acids and flavonoids being the largest subgroups.
Methyl jasmonate was identified as a key regulator enhancing the synthesis of polyphenols and terpenes.
