In
this study, the effects of white light-emitting diode (LED)
and UV-C radiation (with the same intensity) on stilbene biosynthesis
and phytochemicals accumulation of peanut sprouts were investigated.
Results showed that white light radiation promoted the growth of peanut
sprouts while UV-C radiation had the opposite effect. Contents of
total phenolics, total flavonoids, and phytochemicals significantly
increased in peanut sprouts treated by white light or UV-C radiation.
Besides, light radiation significantly induced stilbene accumulation
by upregulating the expression of genes and enzymes in stilbene biosynthesis-related
pathway, and UV-C was more effective to promote stilbene accumulation.
Compared with piceid and piceatannol, resveratrol showed the highest
accumulation in peanut sprouts treated by light radiation. In summary,
white light or UV-C radiation could be used as a method to promote
stilbene biosynthesis and phytochemicals accumulation in peanut sprouts
and UV-C was more effective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
