title: Visualization of flavonol distribution in the abaxial epidermis of onion scales via detection of its autofluorescence in the absence of chemical processes.
abstract: We visualized flavonol distribution in the abaxial epidermis of onion scales without chemical processes via detection of blue-light-induced green autofluorescence. Our visualizing results indicated an unequal intercellular distribution of flavonols among epidermal cells causing a patch distribution in the epidermis, and indicated that flavonol accumulation in ultraviolet irradiated-onion scales was in uniformity with epidermal cells, probably to compensate for their stress-hypersensitiveness.
