“…Quadrana et al (2013) and Vinutha et al (2017) reported that increased transcript level of core tocopherol pathway genes was directly correlated with tocopherol content in tomato and soybean seeds, respectively. Bansal et al (2020) reported enhancement in tocopherol content in soybean genotypes irradiated with 0.5 kGy dose is well correlated in this study as tocopherol pathway genes induced more at 0.5 kGy dose of γ-irradiation. Kim et al (2005) showed increase in SOD and APX enzyme activity on exposure to low doses of γ-irradiation suggesting induction in the respective genes of these enzymes in Capsicum annuum L. cv.…”

Aim: The present investigation was aimed to determine the effect of gamma radiation on genes encoding for tocopherol pathway and antioxidant enzymes in two contrasting soybean genotypes seedlings. Methodology: Seeds from two contrasting soybean genotypes (Bragg and DS-74) were exposed to two different doses of gamma irradiation (0.5 and 1.0 kGy), allowed to germinate and RNA was extracted for cDNA synthesis from 3-days-old soybean seedlings. Expression level of tocopherol pathway and antioxidant enzymes genes was carried out using real time PCR. Seed vigour and moisture contents in seeds of both the soybean genotypes were also analysed. Results: Genes encoding tocopherol biosynthesis and redox enzymes showed higher expression upon 0.5 kGy seed irradiation [3.01 and 3.5 fold for SOD and APXandγ-TMT and MPBQ-MT genes (2.87 and 4.21 fold respectively) in Bragg soybean seedlings] as compared at 1.0 kGy dose of gamma irradiation. The moisture content in control and irradiated soybean seed samples ranged from 8.1 to 15.2 % with DS-74 control seeds showing highest moisture content (15.2%) and Bragg seeds (0.5 kGyirradiated) with lowest moisture content (8.1%). 0.5 kGy irradiated Bragg seeds showed highest seed vigour in the form seed germination (72.25 %) and seedling emergence (61.12%). Interpretation: The result showed that 0.5 KGy of γ- irradiation of soybean seeds were more effective in improving the seed quality by enhancing gene expression of tocopherol pathway and antioxidant enzymes.

“…Conversely, yellow and green-coated soybeans demonstrated a notable enhancement in these attributes at radiation doses of 0.5 and 2 kGy. Moreover, Krishnan et al [44] and Bansal et al [45] reported that an effective improvement in extractable antioxidant activities and the preservation of nutraceutical properties was achieved with the application of a lower dose, specifically 0.5 kGy.…”

Soybean has the potential to be termed the “crop of the future” due to its significant capacity to address protein-energy malnutrition and hidden hunger, particularly in developing countries where diets are predominantly based on wheat and rice. Despite its substantial nutritional value, numerous health benefits, and its versatility in various food and industrial applications, soybean’s full potential remains underutilized due to inherent off-flavors and the presence of antinutritional factors (ANFs). Gamma irradiation is known to have a positive impact by inducing structural and chemical changes in biomolecules like carbohydrates, lipids, proteins, and other phytochemicals. This process leads to improved functionality and market demand by reducing ANFs and the off-flavor in soybeans. Scientifically, it has been demonstrated that low to moderate doses of gamma radiation, up to 10 kGy, can positively influence the antioxidant capacity of soybeans. This, in turn, helps control lipid and protein oxidation, reducing the generation of off-flavors and enhancing the quality and nutraceutical potential of soybeans.
