Augmentation of major isoflavones in Glycine max L. through the elicitor-mediated approach

Abstract

-Isoflavone content in soybean seeds was enhanced by the elicitor-mediated approach under field conditions through the floral application of abiotic elicitors-salicylic acid, methyl jasmonate and biotic elicitors-Aspergillus niger and Rhizopus oligosporus. Among isoflavones, daidzein and glycitein were found to be highly responsive to elicitors, with an increase of 53.7% and 78.7%, respectively as compared to control. Highest total isoflavone content (1276.4 mg g -1 of seeds) was observed upon the administration of 0.1 mM salicylic acid, which is 92.7% higher than in control. This study would be valuable for augmentation of the isoflavone content in soybean seeds in field grown plants for better nutraceutical potential.

Gene expression of glycyrrhizin acid and accumulation of endogenous signaling molecule in Glycyrrhiza uralensis Fisch adventitious roots after Saccharomyces cerevisiae and Meyerozyma guilliermondii applications

“…The previous studies reported that Saccharomyces enhanced the production of secondary metabolites to a great extent . Signaling molecules, including jasmonic acid (JA), salicylic acid (SA) and nitric oxide (NO), were previously studied for their effects on plants and microorganisms . JA signaling pathway plays a role as transducer in accumulating the secondary metabolites in THE treatment group .…”

Carotenoids from fruits and vegetables: Chemistry, analysis, occurrence, bioavailability and biological activities

“…Exogenous application of 25 ppm methyl jasmonate (MJ) and salicylic acid (SA) was also shown being beneficial for enhanced production of carotenoids through differential regulation (more than 6-fold up-regulation) of carotenoid biosynthetic genes in red algae ( Various biotic and abiotic elicitors have been used in fruits and vegetables at preharvest and post-harvest stages for quantitative enhancement of bioactive compounds, antioxidant activity and economic yield (Baenas, et al, 2014;Saini, et al, 2013); however information about functional efficiency of elicitors is scare. Thus, the effect elicitors on bioaccessibility and bioavailability of health promoting compounds should be analyzed to justify the functional benefits of elicitation.…”

LC–ESI–MS based characterisation of isoflavones in soybean (Glycine max (L.) Merr.) from India

“…Numerous factors influence the isoflavone content in the soybean varieties: growth stage, planting location, variety, cropping year, climate, country of origin, and seed weight etc., and all factors might contribute for alteration in the isoflavone levels in soy varieties (Riedl et al 2007;Sakthivelu et al 2008;Saini et al 2013;Zhang et al 2014). Similarly, major differences in the levels of individual isoflavones were observed within the three soybean cultivars viz., Hrvatica, Lea, Danica from Croatia, wherein, TI content ranged from 80.7 to 213.6 mg/100 g of soybean, with genistein as the most abundant isoflavone (Mujić et al 2011).…”
