Ion beam mutagenesis is an advanced technique capable of inducing substantial changes in plants, resulting in noticeable alterations in their growth. However, the precise molecular mechanisms underlying the effects of radiation on soybeans remain unclear. This study investigates the impact of ionizing radiation on soybean development through a comprehensive approach that integrates transcriptomics and metabolomics.

The study consisted of 87 patients with dentofacial deformity: Class II (30 patients), Class III (37 patients), and asymmetry (20 patients). Pearson's chi-squared test and ANOVA were used to analyze the differences in smile characteristics across the preoperative groups.

- Low temperatures negatively impact soybean growth, with varying effects on different cultivars; this study focuses on the cold-tolerant KD52 and cold-sensitive DS17.
- The examination of physiological responses showed that DS17 is more susceptible to damage (high malondialdehyde levels) while KD52 has stronger antioxidant defenses, indicated by the increased activity of enzymes like peroxidase and superoxide dismutase.
- Transcriptomic analysis identified 234 key genes that differ in expression between the two cultivars under cold stress, suggesting that understanding these genes could lead to improved cold resilience in soybeans.
Vegetative soybean (maodou or edamame) serves as a nutrient-rich food source with significant potential for mitigating global nutritional deficiencies. This study undertook a thorough examination of the nutritional profiles and transcriptomic landscapes of six soybean cultivars, including three common cultivars (Heinong551, Heinong562, and Heinong63) and three fresh maodou cultivars (Heinong527, HeinongXS4, and HeinongXS5). Nutrient analysis of the seeds disclosed notable differences in the levels of protein, fat, soluble sugars, vitamin E, calcium, potassium, magnesium, manganese, iron, and zinc across the cultivars.

- Seed hardness is an important trait for soybean consumption and processing, and this study aimed to understand its genetic basis in a population of 234 recombinant inbred lines (RILs).
- The research revealed significant genetic variation in seed hardness among RILs, with six quantitative trait loci (QTLs) identified, particularly focused on chromosome 2 and 16, with qHS-2-1 being the most influential.
- The study found potential candidate genes, including Glyma.02G307000, linked to seed hardness, and differences in gene expression between parent varieties were noted, paving the way for future research and improvements in soybean crops.
Introduction: Rhizosphere microorganisms can effectively promote the stress resistance of plants, and some beneficial rhizosphere microorganisms can significantly promote the growth of crops under salt stress, which has the potential to develop special microbial fertilizers for increasing the yield of saline-alkali land and provides a low-cost and environmentally friendly new strategy for improving the crop yield of saline-alkali cultivated land by using agricultural microbial technology.
Methods: In May 2022, a field study in a completely randomized block design was conducted at the Heilongjiang Academy of Agricultural Sciences to explore the correlation between plant rhizosphere microorganisms and soybean growth in saline-alkali soil. Two soybean cultivars (Hening 531, a salt-tolerant variety, and 20_1846, a salt-sensitive variety) were planted at two experimental sites [Daqing (normal condition) and Harbin (saline-alkali conditions)], aiming to investigate the performance of soybean in saline-alkali environments.
Article Synopsis
- * Research conducted in 2019 and 2020 compared two cultivation methods—ridge with biodegradable film (RB) and conventional flat land (CF)—under various deficit irrigation strategies to analyze their impact on soybean growth.
- * Results indicated that the RB-IBP treatment, which optimizes both rainwater collection and irrigation timing, significantly improved soybean yield and photosynthetic efficiency compared to the CF method, making it a superior water-saving strategy.
