“…Similarly, cultivar BRS 413 RR differed from DM 6563 with a lignin content of 4.84 g/% compared to 4.45 g/% ( Figure 7 ). These results corroborate what was observed in other studies for the BRSMG 715A cultivar and other black seed coat genotypes [ 9 , 17 , 24 ]. Additionally, cultivars with black seed coats stand out for having a higher concentration of phenolic compounds such as anthocyanin and flavonoids [ 75 ].…”

“…Although most commercial soybean cultivars have a yellow seed coat, the black seed coat of soybeans has properties that make it attractive both for seed and grain use. For instance, higher concentrations of phenolic compounds such as anthocyanins, carotenoids, and lignin are found in black-seeded compared to yellow-seeded soybeans [ 8 , 9 ].…”

Soybean is the primary source of vegetable protein and is used for various purposes, mainly to feed animals. This crop can have diverse seed coat colors, varying from yellow, black, brown, and green to bicolor. Black seed coat cultivars have already been assigned as favorable for both seed and grain production. Thus, this work aimed to identify genes associated with soybean seed quality by comparing the transcriptomes of soybean seeds with contrasting seed coat colors. The results from RNA-seq analyses were validated with real-time PCR using the cultivar BRS 715A (black seed coat) and the cultivars BRS 413 RR and DM 6563 IPRO (yellow seed coat). We found 318 genes differentially expressed in all cultivars (freshly harvested seeds and seeds stored in cold chamber). From the in silico analysis of the transcriptomes, the following genes were selected and validated with RT-qPCR: ACS1, ACSF3, CYP90A1, CYP710A1, HCT, CBL, and SAHH. These genes are genes induced in the black seed coat cultivar and are part of pathways responsible for ethylene, lipid, brassinosteroid, lignin, and sulfur amino acid biosynthesis. The BRSMG 715A gene has almost 4times more lignin than the yellow seed coat cultivars. These attributes are related to the BRSMG 715A cultivar’s higher seed quality, which translates to more longevity and resistance to moisture and mechanical damage. Future silencing studies may evaluate the knockout of these genes to better understand the biology of soybean seeds with black seed coat.

“…Mertz et al (2009) and Bahry et al (2017) found that seeds with a black seed coat (that have anthocyanin accumulation in the seed coat) have greater physiological quality than those with a yellow seed coat. Furthermore, Bahry et al (2015) found that soybean seeds with a black seed coat have a greater concentration of phenolic compounds and antioxidant potential than those with a yellow seed coat.…”

Metabolites of the phenylpropanoid pathway and physiological quality of soybean seeds in storage

et al. 2021

The aim of this study was to evaluate changes in the physiological quality of soybean seeds throughout a storage period in two environments, and to evaluate how these changes are related to metabolites of the phenylpropanoid pathway. A completely randomized experimental design was used in a 4 × 8 factorial arrangement (storage periods × cultivars) with four replications. We used seeds from cultivars with contrasts in lignin content, color, and presence of anthocyanin in the seed coat, and isoflavone content in the seed. The seeds were kept for six months under cold and dry storage and in a non-controlled environment. Germination, first germination count, seedling emergence, and tetrazolium testing were performed on the seeds every two months. The physiological quality of the seeds declines during the storage period, with higher rates of decrease in the non-controlled environment. The metabolites of the phenylpropanoid pathway that were studied, especially lignin, affect seed storage potential. Cultivars with higher lignin content show greater storage potential, especially in a non-controlled environment.

“…This result demonstrates that the seeds of the tested cultivars, with seed coat lignin contents between 3 and 5% (Table 5), similarly to most cultivars currently sold on the market, do not differ in terms of water uptake. For Bahry et al (2015), seed water uptake is more closely related with the genotypeenvironment interaction than with the relationship between seed coat and lignin concentration. However, it is important to highlight the relationship of lignin with some attributes that make up seed quality, as mentioned by Krzyzanowski & França-Neto (2021).…”

The identification of pod-and seed-related traits of soybean genotypes and their interaction with water uptake can be applied in breeding programs with a view to establishing cultivars developed for the production and maintenance of high-quality seeds. The objective was to evaluate the water uptake of pods and seeds of soybean cultivars with different lignin contents after different soaking periods. The experimental was arranged in a completely randomized, 7×10 factorial design, with four replications. The factors consisted of seven soybean cultivars and 10 soaking periods (1, 2, 3, 4, 5, 6, 7, 8, 24, 48 hours). The pods and seeds were grown in a greenhouse and harvested at the phenological growth stage R8 (at full maturation, when 95% of the pods had mature color). The following traits were evaluated: lignin content in pod and seed coat, moisture content, and rate of water uptake of pods and seeds. Soybean cultivars with pods with high lignin contents have a lower rate of water uptake. The lignin contents of the seed coats, within the chosen limits, did not affect the seed water uptake.
