目的：在本研究中，我们的工作假设是，连续光照和真菌诱导处理的豆科植物幼苗会导致叶绿素和可溶性蛋白水平的提高。结果：基于短期光照和黑暗处理，叶绿素（染料木黄酮，染料木苷，大豆苷元和大豆苷）和可溶性蛋白浓度在“光”下显著上调。 对于测试的所有可食用豆类物种（菜豆、大豆、鹰嘴豆、蚕豆、绿豆、红小豆），将“黑暗”环境与“黑暗”环境进行比较。葛藤幼苗表现出最高的 与其他分析的豆类相比，光诱导上调后的蛋白质和可溶性蛋白质的水平。大豆疫霉真菌诱导子处理后，所有豆科植物的叶绿素合成均表现出较小的上调。结论：本研究的结果表明，可食用豆类幼苗的生长， 当它们在光照下生长时，与在黑暗中生长这种幼苗的常规实践相比，它们的叶绿素和可溶性蛋白质的水平。这显然将导致重大改善 营养和药用价值。
Objective:In this study, our working hypothesis was that continuous light and fungal elicitation treatment of legume seedlings would lead to enhanced levels of isoflavonoids and soluble proteins.Results:Based on short-term light and dark treatments, isoflavonoid (genistein, genistin, daidzein, and daidzin) and soluble protein concentrations were significantly upregulated in the "light" environment compared to the "dark" environment for all edible legume species (kudzu vine, soybean, garbanzo bean, fava bean, mung bean, adzuki bean) that were tested. Kudzu seedlings showed the highest levels of both isoflavonoids and soluble proteins after light-elicited upregulation compared to the other legumes analyzed. All legumes showed less up-regulation of isoflavonoid synthesis when treated withPhytophtora sojaefungal elicitor. Oligosaccharide fungal elicitor caused no such upregulation.Conclusions:The findings in this study show that edible legume seedlings have enhanced levels of isoflavonoids and soluble proteins when they are grown in the light compared to the conventional practice of growing such seedlings in the dark. This will clearly result in significant improvement in their nutritive and medicinal value.
