“…59 Chin et al reported that daidzein, daidzin and genistin showed similar antibacterial activities against Bacillus subtilis, Pseudomonas aeruginosa and Staphylococcus aureus, among other studied bacteria. 60 By contrast, our study indicated that genistin shows stronger antibacterial activity against Xag compared with daidzein and daidzin. It must be noted that the structure of genistin consists of genistein linked to a glucose moiety in position 7 and, similarly, the structure of daidzin consists of daidzein linked to a glucose moiety in the same position.…”

BACKGROUND Xanthomonas axonopodis pv. glycines (Xag) is the causal agent of bacterial pustule disease and results in enormous losses in soybean production. Although isoflavones are known to be involved in soybean resistance against pathogen infection, the effects of exogenous isoflavones on soybean plants remain unexplored. RESULTS Irrigation of soybean plants with isoflavone genistein inhibited plant growth for short periods, probably by inhibiting the tyrosine (brassinosteroids) kinase pathway, and increased disease resistance against Xag. The number of lesions was reduced by 59%–63% when applying 50 μg ml−1 genistein. The effects on disease resistance were observed for 15 days after treatment. Genistein also enhanced the disease resistance of soybean against the fungal pathogen Sclerotinia sclerotiorum. Exogenous genistein increased antioxidant capacity, decreased H2O2 level and promoted the accumulation of phenolics in Xag‐infected soybean leaves. Exogenous genistein reduced the amounts of endogenous daidzein, genistein and glycitein and increased the concentration of genistin, which was found to show strong antibacterial activity against the pathogen and to reduce the expression of virulence factor yapH, and flagella formation gene flgK. The expression of several soybean defense genes, such as chalcone isomerase, glutathione S‐transferase and 1‐aminocyclopropane‐1‐carboxylate oxidase 1, was upregulated after genistein treatment. CONCLUSIONS The effects of exogenous genistein on soybean plants were examined for the first time, revealing new insights into the roles of isoflavones in soybean defense and demonstrating that irrigation with genistein can be a suitable method to induce disease resistance in soybean plants. © 2022 Society of Chemical Industry.

“…Chin et al. (2012) indicated that daidzein, daidzin, and genistin showed similar antibacterial activities against foodborne Bacillus subtilis , Pseudomonas aeruginosa , and Staphylococcus aureus . The identification of the specific isoflavones found in the sprouts of different cultivars can help form a better understanding of their intrinsic resistance to pathogen infection and the cultivars that offer medium‐high levels of resistance, which may improve the production of soybean sprouts and reduce pathogen‐derived losses.…”

Sprouting is a common strategy to enhance the nutritional value of seeds. Here, all the reports regarding the occurrence of isoflavones in soybean sprouts have been covered for the first time. Isoflavones were detected with concentrations ranging from 1 × 10–2 to 1 × 101 g/kg in soybean sprouts. Isoflavone concentration depends on the cultivar, germination time, part of the sprout, light, and temperature. Aglycon isoflavones increased during germination, especially in the hypocotyl, while 6″‐O‐malonyl‐7‐O‐β‐glucoside isoflavones decreased in the hypocotyl and increased in the cotyledon and root. Cooking reduced total isoflavone content. Regarding the strategies to enhance isoflavone contents, fermentation with Aspergillus sojae and external irradiation with UV‐A or far‐infrared were the methods that caused the greatest increases in aglycon, 7‐O‐β‐glucoside, and total isoflavones. However, the largest increases in 6″‐O‐malonyl‐7‐O‐β‐glucoside and 6″‐O‐acetyl‐7‐O‐β‐glucosides isoflavones were detected after treatment with chitohexaose and calcium chloride, respectively. Practical Application Soybean sprouts are widely consumed and provide essential proteins, antioxidants, and minerals. They are rich in isoflavones, which exhibit numerous health benefits, and have been studied as alternative therapies for a range of hormone‐dependent conditions, such as cancer, menopausal symptoms, cardiovascular disease, and osteoporosis. Despite numerous reports being published to date regarding the occurrence of isoflavones in soybean sprouts, the publications in this field are highly dispersed, and a review has not yet been published. This review aims to (1) highlight the particular isoflavones that have been detected in soybean sprouts and their concentrations, (2) compared the effects of temperature, light, cooking and soybean cultivar affect the isoflavone levels on the different parts of the sprout, and (3) discuss the efficacy of the methods to enhance isoflavone contents. This review will provide a better understanding of the current state of this field of research by comparing the general trends and the different treatments for soybean sprouts.

“…The history of humanity, from the medical point of view, can be considered a battle against infectious diseases. In the beginning of the 21st century, the occurrence of bacterial infections resistant to drugs became common and research to develop new drugs with antimicrobial activity has spread to new clinical areas (Harbarth and Samore, 2005, Chin et al, 2012). Accordingly, natural products from plants are interesting alternatives for solving this problem, since many plant extracts and their phytochemical constituents are known to have antimicrobial activities (Coutinho et al, 2009a).…”

The development of new drugs from plants is an interesting alternative approach to overcoming microbial resistance. shows resistance to diseases and pests and a higher concentration of chemical components that may be useful in the pharmaceutical industry. We investigated the potential antimicrobial and antibiotic-modifying activity of hydroalcoholic extracts of leaves, stems, bark, pulp and seeds of. The extracts were prepared by homogenization of material in 50% ethanol. Minimum inhibitory concentration (MIC) was determined by the broth dilution method, and the bacterial strains tested were and. Antibiotic-modifying activity was evaluated against the strains 03 and 08, using a subinhibitory concentration of extract. The antibiotics tested were: amikacin, gentamicin, ampicillin, potassium benzylpenicillin and oxacillin. The extracts did not show antimicrobial activity of clinical relevance, where the MIC was equal to or greater than 1024 μg/mL. showed 13 events, while showed only 4 events. Among these events, 14 involved synergistic activity, potentiating the effect of the antibiotics, and only 3 events demonstrated antagonistic activity toward ampicillin. Hydroalcoholic extracts are potential antimicrobial agents when combined with conventional drugs little utilized in treatment.
