“…During the reproductive growth stage (R5), leaf redistribution is the main source of nitrogen in the pods (Taniguchi et al, 2018). After drought treatment, the nitrogen content in the pods of HN44 decreased significantly, while the remaining parts did not change significantly, indicating that the nitrogen flow in the plant was stagnant and the process of leaf redistribution to the pod was significantly inhibited (Fig 6C).…”

Background: Soybeans are the main sources of oil and protein for most of the global population. As the population grows, so does the demand for soybeans. However, drought is a major factor that limits soybean growth. Methods: The nitrogen content in different parts of the soybean under drought stress and rehydration was investigated using the soybean cultivars, HN44 and HN65, at different growth stages (vegetative growth, parallel period of vegetative growth and reproductive growth and reproductive growth). Result: During the vegetative growth stage, drought decreased the plant’s nitrogen content. After rehydration, all the organs showed different degrees of compensatory effects. During the parallel period of vegetative and reproductive growth, drought decreased the nitrogen content of the leaves. After rehydration, the nitrogen content was partially restored. During the reproductive growth period, drought affected the translocation of nitrogen to the sink. After rehydration, the nitrogen content increased in the pods and decreased in other parts. In summary, rehydration after drought during the vegetative growth period of soybean can lead to nitrogen accumulation, but the reproductive growth phase differs from earlier; therefore, this period should avoid drought stress.

“…Pod shattering rate is one of the main determinants of soybean yield. Using two different genotypes of the soybean crop, researchers Taniguchi et al (2018) studied the association between plant growth facilitated by gibberellin and pod setting ratio. After flowering, the plant growth rate was meaningfully improved in Fukuyutaka and lower in the Kariyutaka genotype.…”

The soybean is one of the most significant legume crops around the globe and serves as a source of dietary components for humans and animals. It has a higher percentage of protein compared to any other crop. Soybean yield and quality have been affected by many environmental factors. The genetic mechanism of yield and quality is still not clearly understood. Hence there is still a need to investigate the major potent factors to shed light on the mechanism behind yield and quality traits in soybean. Recently, a lot of significant work, including novel QTL, genes, and CRISPR-based genome editing in soybeans, has been done, which opened new doors of hope. The current review has presented detailed work done previously. We have also discussed the role of different breeding techniques in the conventional way of soybean improvement. The genetic factors regulating yield, quality, and disease resistance could be further cloned and transferred into elite cultivars to attain higher output in the current situation of changing environment. The integrated use of several techniques, like CRISPR/Cas9, next-generation sequencing, omics approaches, would be a fruitful way to improve soybean yield and quality. Besides this, hybridization, mass selection, pure line selection, backcross breeding, and pedigree selection should be adopted to develop novel soybean cultivars. This review concluded that soybean yield and quality improvement could be enhanced by exploring its genetic mechanism using several molecular and conventional methods.

“…Four-seed pods are more likely to form in the upper and middle parts than in the lower part of the stem (Liu, Yao, et al, 2015). Previous studies have conducted many genetic mapping analyses on the number of four-seed pods using different genetic populations (Li et al, 2020;Taniguchi et al, 2018). With the development of high-throughput sequencing technology, the analysis of whole-genome resequencing and transcriptome sequencing data to map traits associated with soybean pods and seeds has been ongoing (Liu, Yao, et al, 2015;Teng et al, 2019;Wang et al, 2015).…”

Previous studies have conducted many genetic mapping analyses on the number of four‐seed pods using different genetic populations (Li et al, 2020; Taniguchi et al, 2018). Sayama et al (2017) evaluated the pleiotropic effects of Ln on leaf shape and pod number using the Gm‐jag1 mutant and SmartGrain image software for leaf shape analysis, indicating that the pleiotropic effects of the Ln gene in soybean control leaf shape and pod number.…”

Gene mining of 100‐grain weight and the number of four‐seed pods in soybean (Glycine max)

The number of four-seed pods and 100-grain weight are important yield components in soybean. Typically, they are negatively correlated traits. Generally, soybean varieties with a high 100-grain weight and a higher number of three-or four-seed pods are more likely to obtain a high yield. It is difficult to select for double-excellent traits that meet the needs of farmers and the market using conventional breeding methods.The purpose of this study was to mine genes associated with the number of fourseed pods and 100-grain weight in soybean. Whole-transcriptome sequencing was performed on four specific chromosome segment substitution lines (HWMN, HWFN, LWMN and LWFN) combined with the distribution of blocks imported from wild soybean DNA fragments and gene annotation. The material was sampled in each of the eight development stages. Among them, globular embryo formation, heart embryo formation, and cotyledon primordium formation were used to mine differentially expressed genes (DEGs). A total of 3792 DEGs were identified, and 25 expression patterns were obtained by the K-means rapid clustering method. GO enrichment analysis of DEGs was performed by Agrigo, and a total of 43 GO terms were enriched. Through annotation analysis, 126 DEGs associated with seed size and number were obtained. Combined with analysis of the introduced DNA fragments of wild soybean ZYD00006, 19 genes that eventually aligned on those blocks were obtained.Six representative genes were selected as candidate genes, namely,
