“…Generally, in this study, environments which were warmer and drier resulted in less seed isoflavone levels across all genotypes than those environments which were cooler and wetter, consistent with previous studies (Tsukamoto et al 1995;Caldwell et al 2005;Lozovaya et al 2005). Mean isoflavone level ranged from 1600 to 3700 mg g (1 across the 10 environments.…”

“…This relationship is most likely a function of the relationship between temperature during seed fill and isoflavone accumulation. Cooler temperatures during the seed fill period increase isoflavone content (Caldwell et al 2005;Lozovaya et al 2005;Murphy 2007). The positive relationship between isoflavone content and maturity may be related to the timing of seed filling in later maturing lines, which occurs later in the season when temperatures can be expected to usually be lower in the Canadian soybean production regions.…”

. 2009. Association of seed and agronomic traits with isoflavone levels in soybean. Can. J. Plant Sci. 89: 477Á484. Soybean, Glycine max (L.) Merr., seeds contain isoflavones, compounds with potential human health benefits. This study investigated the association of seed and agronomic traits with isoflavone level in a genetically diverse group of soybean genotypes to provide more information for cultivar development. F 4:7 lines derived from several crosses were grown in four locations in 2005 and six locations in 2006 across Ontario and Quebec. Seed protein, oil and isoflavone contents were measured using near-infrared reflectance (NIR) on a plot basis. Seed yield was determined at 13% moisture and days to maturity (R8) were recorded. GGE genotype-bytrait biplots were generated to describe the relationships among all variables. Isoflavone content was not correlated with yield, indicating that potential exists for development of high or low isoflavone cultivars without sacrificing yield. Isoflavone content was negatively correlated with protein content, however high isoflavone lines were identified with moderate protein content. Isoflavone content was correlated with maturity suggesting that delayed planting and/or the use of later maturing varieties could be a successful strategy to increase isoflavone content. The results of this study support the potential for the development of either high or low isoflavone soybean cultivars with acceptable agronomic and seed quality traits.Key words: Soybean, isoflavone, protein, oil, yield, maturity Murphy, S.

“…Isoflavones accumulation over environments or their concentrations in plants varied widely (Hoeck et al, 2000;Mebrahtu, Mohamed, Wang, & Andebrhan, 2004;Caldwell, Britz, & Mirecki, 2005;Lozovaya, Lygin, Ulanov, Nelson, Dayde, & Widhohm, 2005) and generally plants are conducive to accumulate more isoflavone when growing in a controlled environment. This might due to desire well-watered and temperature condition.…”

Seed isoflavone content of soybean (Glycine max L. Merr.) is a trait of moderate heritablity and an ideal target for marker selection. To date over 20 QTL have been identified underlying this trait among seven populations. The objectives of this study were to identify additional QTL and candidate genes controlling isoflavone content in a set of recombinant inbred line (RIL) populations of soybean grown in two different seasons. Variations of isoflavones namely daidzein, glycitein and genistein contents over two growing seasons and locations suggests that isoflavones are influenced by both genes and environments. Six QTL were identified on five different chromosomes (Chr) or linkage groups (LG) that controlled daidzein (Chr_2/LG-M; Chr_17a/LG-D2), glycitein (Chr_2/LG-D1b; Chr_8/LG-A2) and genistein (Chr_8/LG-A2; Chr_12/LG-H) respectively in the seeds grown in season 2010. Two QTL were identified for daidzein (Chr_6/LG-C2; Chr_13b/LG-F), two QTLs for glycitein (Chr_1/LG-D1a; Chr_17c/LG-D2) and five QTLs for genistein (Chr_3/ LG-N; Chr_8/LG-A2; Chr_9/LG-K; Chr_18/LG-G) in the seeds of the 2011 growing season. Genes located within QTL confidence intervals were retrieved and gene ontology (GO) terms were used to identify those related to the flavonoid biosynthesis process. Twenty six candidate genes were identified that may be involved in isoflavones accumulation in soybean seeds.

“…Other researchers found that synthesis and accumulation of isoflavones were affected by irrigation, and irrigation increased isoflavones by 2.5 folds [66,67]. It was concluded that soil moisture increased daidzein, genistein and total isoflavones, but not glycitein when water stress was imposed at R6 [68]. Up to 45% increase of isoflavones was measured under irrigated conditions versus nonirrigated conditions [67].…”

Previous research showed that foliar boron (B) application at flowering or seed-fill growth stages altered seed protein, oil, and fatty acids. The objective of this research was to investigate the effects of foliar B fertilizer on seed phenolics (phenol, lignin, and isoflavones) and sugars concentrations. A repeated greenhouse experiment was conducted on soybean [(Glycine max(L.) Merr.)] under watered and water-stressed conditions. Soybean plants were divided into different sets, and each set was subjected to one of the following treatments: W = plants were watered with no foliar B; WB = plants were watered and received foliar B; WS = plants were water-stressed with no foliar B; WSB = plants were waterstressed and received foliar B. Foliar B was applied at rate of 0.45 kg/ha twice at flowering and twice at seed-fill stages. The results showed that total phenol and lignin concentrations were higher in seed collected from water-stressed plants compared with those collected from watered plants whether B was applied or not. The higher total phenol and lignin concentration in seed collected of water-stressed plants may be due to B-deficiency in plant tissues. Application of B resulted in higher concentrations of total seed B and isoflavones under watered and water-stressed plants. Higher cell wall B was higher in water-stressed plants than in watered plants, having an opposite trend to total B. Application of B resulted in higher seed sucrose in watered and water-stressed plants, but raffinose and stachyose were significantly higher under water-stressed plants. The research demonstrated that foliar B fertilizer altered seed phenol, lignin, isoflavones, and sugars, suggesting that B involved in phenolics and sugar metabolism. The higher cell wall B in waterstressed plants than in watered plants supports previous research that B has mainly a structural role. The higher sucrose resulting from foliar B in watered plants is desirable as sucrose contributes to seed quality. The increase of raffinose and stachyose concentrations in seed of water-stressed plants is undesirable as raffinose, and especially stachyose may be involved in water stress/drought tolerance. The current knowledge would help soybean breeders select for higher phenolic compounds and desirable sugars for higher seed qualities under drought conditions.
