Light Spectral Composition Modifies Polyamine Metabolism in Young Wheat Plants
International Journal of Molecular Sciences, 2022 Although light-emitting diode (LED) technology has extended the research on targeted photomorphogenic, physiological, and biochemical responses in plants, there is not enough direct information about how light affects polyamine metabolism. In this study,
