Metabolite Contents and Antioxidant Activities of Soybean (Glycine max (L.) Merrill) Seeds of Different Seed Coat Colors.

ABSTRACT: Seed coat color is one of the main agronomical traits that determine the chemical quality of soybean seeds and has been used as a parameter during cultivar development. In this study, seeds of yellow (n = 10), greenish-yellow (n = 5), and light-yellow (n = 4) soybean accessions were evaluated for their contents of total protein, total oil, total phenolic (TPC), and five prominent fatty acids including palmitic acid (PA), stearic acid (SA), oleic acid (OA), linoleic acid (LA), and linolenic acid (LLA), relative to a control cultivar, and the effect of seed coat color on each was investigated. Antioxidant activity was also evaluated using 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, Trolox equivalent antioxidant capacity (TEAC), and ferric reducing antioxidant power (FRAP). The results showed significant variations of metabolite contents and antioxidant activities between the soybeans. The average TPC, DPPH-radical scavenging activity, and FRAP were each in the order of greenish-yellow > yellow > light-yellow soybeans. In contrast, light-yellow soybeans contained a high level of OA and low levels of SA, LA, and LLA, each except LA differing significantly from yellow and greenish-yellow soybeans (p < 0.05). Our findings suggest that greenish-yellow and light-yellow soybeans could be good sources of antioxidants and high-quality soybean oil, respectively.

Project description:The present study is an attempt to establish a fast, highly reproducible transformation with a simplified regeneration system in soybean targeting the apical meristem. The modified half-seed explants from soybean cultivar (cv.) JS335 were subjected to different time intervals of sonication (0, 1, 10, 20, and 30 min) and vacuum infiltration (0, 1, 10, 20, and 30 min) in the presence of Agrobacterium tumefaciens strain EHA105 harbouring pCAMBIA1301. The explants were then co-cultivated and subjected to a modified plant regeneration process that involves only two steps (1) primary shoot regeneration, and (2) in vitro rooting of primary shoot. The rooted plantlets were hardened and maintained in the greenhouse until maturity. Sonication treatment of 10 min, followed by plant regeneration using a modified method, recorded the highest transformation efficiency of 26.3% compared to other time duration tested. Furthermore, 10 min of vacuum infiltration alone resulted in even higher transformation efficiency after regeneration, reaching 28.0%. Interestingly, coupling sonication and vacuum infiltration for 10 min respectively produced the highest transformation efficiency after regeneration of 38.0%. The putative transformants showed gus expression in mature leaves, trifoliate leaves, flowers, and pods. The presence of hpt II was also confirmed in putative transformants, with an amplicon size of 500 bp. Quantitative real-time PCR confirmed the existence of hpt II as one to two copies in the soybean genome of T0 plants. Furthermore, the segregation pattern was observed in the T1 generation soybean plants which were confirmed using PCR for hpt II. The optimized protocol when tested with other Indian soybean cultivars showed an enhanced transformation efficiency ranging from 19.3% (cv. MAUS47) to 36.5% (cv. CO1). This optimized protocol could provide a reliable platform to overcome the challenges that are associated with the genetic engineering of soybean.Supplementary informationThe online version contains supplementary material available at 10.1007/s13205-023-03715-8.
