“…The protein and oil content of seed in this study were comparable to those reported elsewhere [16,18,19]. While sucrose content were comparable to those reported before [20,21], they are higher than those of vegetable varieties reported in other studies [22]. Seed protein content was affected by interaction of the production system and variety (P<0.05).…”

Soybean [Glycine max (L.) Merr.], a legume native to East Asia contains up to 40% protein and 20% oil. Edamame, a popular vegetable soybean in East Asia, especially China and Japan, harvested at reproductive stages six and seven (R6 or R7) is gaining popularity in the US. Increased awareness of its nutritional quality through promotional campaigns and changing population demographics in the US have led to recent raise in US market demand for edamame. To meet the increasing market demand, frozen edamame from China and Taiwan has been imported. However, the quality of such imported product quickly deteriorates under frozen condition. The objective of this study was to determine whether off-season production systems and staggered planting of different maturity groups (MG) edamame cultivars during the planting season can extend the harvesting window for fresh beans. Four released edamame cultivars of different maturity groups (MG) were used: Gardensoy31 (MG III), Gardensoy41 (MG IV), Mooncake (MG V) and Randolph (MG VI). Total pod yield, marketable pod yield and seed quality traits including protein, oil and sucrose content of each cultivar were determined. The results indicated that early-and mid-spring planting of all MG varieties in the high tunnels allows for pod harvest starting in early July. Planting early in plasticcovered field followed by conventional planting in late-spring allowed harvest in mid-summer through early fall. While total and marketable pod yield differed among cultivars and production systems, seeds had comparable oil content (158 g kg -1 ) and protein and sucrose content range of 370-422 g kg -1 and 33-73 g kg -1 on dry matter, respectively. Use of season extension production techniques and soybean of appropriate MG increases harvest window from two weeks to several months.

“…Increased sucrose content has also been reported in vegetable types of soybean harvested at the R6‐R7 stages, and sucrose content was positively associated with product taste scores (Kumar et al. ). The correlation between sucrose and protein content has been described as negative (Wilcox and Shibles , Cui et al.…”

“…In a world germplasm collection, Hou et al (2009) identified accessions with a sucrose content of over 95 g/kg. Increased sucrose content has also been reported in vegetable types of soybean harvested at the R6-R7 stages, and sucrose content was positively associated with product taste scores (Kumar et al 2011). The correlation between sucrose and protein content has been described as negative (Wilcox and Shibles 2001, Cui et al 2004, Jaureguy et al 2011, which is a major impediment in breeding for food-grade soybeans with increased concentrations for both of these compounds.…”

Effects of divergent selection for seed protein content in high‐protein vs. food‐grade populations of early maturity soybean

et al. 2013

Due to the growing need for vegetable protein in Central European agriculture, there is interest in producing food-grade soybeans, which are higher in seed protein and sucrose content and have a larger seed size than conventional soybeans. As protein content of conventional soybean is often below 400 g/kg, either high-protein or food-grade donors were crossed with adapted genotypes in order to increase their protein level. After divergent selection for protein content, lines were evaluated for seed quality characters across three environments in Austria. The objectives of this research were to determine the roles of genetic background and the selection for protein content on food-grade soybean traits. While seed protein content of adapted parents was between 395 and 420 g/kg, its range was from 410 to 490 g/kg for the high-protein and from 390 to 450 g/kg for the food-grade lines, respectively. However, food-grade populations were superior in seed size and sucrose content and revealed different correlation patterns between quality traits as compared to highprotein populations, which demonstrates their usefulness for developing soybeans with improved quality.

“…Largely due to its higher nutritional content and better flavor compared to grain soybean, vegetable soybean has become very popular in China (300,000 ha planted each year), Southeast Asia, and some Western countries234. However, chilling stress affects vegetable soybean plant growth and results in severe yield reduction5.…”

Chilling stress is a major factor limiting the yield and quality of vegetable soybean (Glycine max L.) on a global scale. In the present study, systematic identification and functional analysis of miRNAs under chilling stress were carried out to clarify the molecular mechanism of chilling resistance. Two independent small RNA libraries from leaves of soybean were constructed and sequenced with the high-throughput Illumina Solexa system. A total of 434 known miRNAs and 3 novel miRNAs were identified. Thirty-five miRNAs were verified by qRT-PCR analysis. Furthermore, their gene targets were identified via high-throughput degradome sequencing. A total of 898 transcripts were targeted by 54 miRNA families attributed to five categories. More importantly, we identified 51 miRNAs differentially expressed between chilling stress and control conditions. The targets of these miRNAs were enriched in oxidation-reduction, signal transduction, and metabolic process functional categories. Our qRT-PCR analysis confirmed a negative relationship among the miRNAs and their targets under chilling stress. Our work thus provides comprehensive molecular evidence supporting the involvement of miRNAs in chilling-stress responses in vegetable soybean.
