我们通过检测蓝光诱导的绿色自发荧光，在没有化学过程的情况下可视化洋葱鳞片远轴表皮中的黄酮醇分布。我们的可视化结果表明，表皮细胞中黄酮醇的细胞间分布不均匀，导致表皮中出现斑块分布，并表明紫外线照射的洋葱鳞片中黄酮醇的积累与表皮细胞是一致的，可能是为了补偿它们的应激过敏性。
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.
