“…Without a spindle, the division wall cannot form, leading to the retention of chromosomes and their copies in the same cell. Polyploid plants that develop from colchicine treatment have improved their adaptation to salt stress by efficiently regulating water usage by varying leaf latex osmotic potential (Mangena 2023). These plants also possess better adaptive abilities in regulating cation toxicity and ions that limit enzyme activity and nucleic acid metabolism than diploids (Manzoor et al 2019).…”

Abstract. Fathurrahman F, Ulpah S, Sodiq NAM, Mahadi I, 2024. The effect of Colchicine treatment on phenotype and genotype characteristics of Detam-2 variety of soybean Glycine max. Biodiversitas 25: 1230-1238. The enhancement of soybean plant mutagenesis to obtain phenotypic and genotypic diversity is essential in agriculture. This study aimed to analyze the effect of colchicine concentration on phenotypic and genotypic characteristics based on RAPD markers of detam-2 variety. The experiments were carried out from January to June 2023 in the experimental farm of the Agriculture Faculty, Universitas Islam Riau, Pekanbaru, Indonesia. Therefore, 600 plants were used, consisting of 200 controls and 400 samples treated with 3,500 ppm of colchicine. The growth parameter was analyzed using a DMRT statistical test at p<0.05, and stomata densities were compared using T-test. The mutant-1 produced the highest yield, a total of 235 pods (with 233 phity pods), seed weighed 93.20 g, which was significantly different from those of controls. Mutant-2 produced the highest dry weight of 100 seeds, which was 12.80 g, with a dry seed weight per plant of 63.30 g. Leaf types in mutant samples varied, including normal, purple leaf stems, and curly leaves. The genotypic study showed that primer OPAA-01 produced a different number of DNA bands. The highest genetic similarity was 0.961 among the controls, while the lowest was 0.451 between mutant-1 and the controls. Based on the results, the dendrogram produced two groups: control and mutant-1.

“…Soybean ( Glycine max ) is a plant of the genus Glycine in the Fabaceae family, and it is one of the most important legumes in the world [ 23 ]. As a crop, soybean frequently suffers diverse metal ion stresses throughout its life cycle, not merely limiting the production but threatening people’s health because of accumulating harmful heavy metallic elements [ 24 , 25 ].…”

Manganese (Mn) is among one of the essential trace elements for normal plant development; however, excessive Mn can cause plant growth and development to be hindered. Nevertheless, the regulatory mechanisms of plant root response to Mn poisoning remain unclear. In the present study, results revealed that the root growth was inhibited when exposed to Mn poisoning. Physiological results showed that the antioxidase enzyme activities (peroxidase, superoxide dismutase, ascorbate peroxidase, and catalase) and the proline, malondialdehyde, and soluble sugar contents increased significantly under Mn toxicity stress (100 μM Mn), whereas the soluble protein and four hormones’ (indolebutyric acid, abscisic acid, indoleacetic acid, and gibberellic acid 3) contents decreased significantly. In addition, the Mn, Fe, Na, Al, and Se contents in the roots increased significantly, whereas those of Mg, Zn, and K decreased significantly. Furthermore, RNA sequencing (RNA-seq) analysis was used to test the differentially expressed genes (DEGs) of soybean root under Mn poisoning. The results found 45,274 genes in soybean root and 1430 DEGs under Mn concentrations of 5 (normal) and 100 (toxicity) μM. Among these DEGs, 572 were upregulated and 858 were downregulated, indicating that soybean roots may initiate complex molecular regulatory mechanisms on Mn poisoning stress. The results of quantitative RT-PCR indicated that many DEGs were upregulated or downregulated markedly in the roots, suggesting that the regulation of DEGs may be complex. Therefore, the regulatory mechanism of soybean root on Mn toxicity stress is complicated. Present results lay the foundation for further study on the molecular regulation mechanism of function genes involved in regulating Mn tolerance traits in soybean roots.

Sulfur deficiency severely limits soybean growth, inhibiting the rhizobia nitrogenase and soybean protein synthesis. This study assessed the impact of sulfur fertilization and rhizobia inoculation on soybean growth and nitrogen fixation through bacterial culture and hydroponic experiments. We selected three rhizobia strains for bacterial cultures and used six sulfur levels. The test demonstrated severe inhibition of Rhizobium USDA110 growth without sulfur. In hydroponic experiment, we employed five sulfur levels with USDA110 as the inoculum strain. Soybean growth, nitrogen fixation, yield, and root morphology-related parameters, and root nodule growth, were significantly inhibited without sulfur. Following Rhizobium inoculation, low sulfur concentrations (0.15–0.60 mM) stimulated early-stage (V9) root growth and increased shoot nitrogen accumulation, but inhibited root growth at R5 stage. Furthermore, Rhizobium inoculation notably enhanced soybean growth, nitrogen fixation, and yield, especially within the recommended low sulfur concentration range (0.15–0.30 mM). The maximum nodule nitrogenase activity at R5 stage and highest yield was recorded at a 0.3 mM sulfur concentration with Rhizobium inoculation, which was 9.51–1222.07% higher than other treatments. These findings highlight that low sulfur concentration and rhizobia inoculation enhance soybean growth, nitrogen fixation, and yield but reduce soybean root efficacy, increasing reliance on root nodules.
