Combined metabolome and transcriptome analysis reveals the key pathways involved in the responses of soybean plants to high Se stress.

High selenium (Se) levels can induce toxicity, inhibit growth, and affect gene expression and metabolite content in plants. However, the molecular mechanism by which high Se stress affects soybean plants remains unclear. This study examined the responses of soybean leaves and roots to high Se stress using transcriptome and metabolome analyses.

The Physiological Response Mechanism of Peanut Leaves under Al Stress.

Aluminum (Al) toxicity in acidic soils can significantly reduce peanut yield. The physiological response of peanut leaves to Al poisoning stress still has not been fully explored. This research examined the influences of Al toxicity on peanut leaves by observing the leaf phenotype, scanning the leaf area and perimeter, and by measuring photosynthetic pigment content, physiological response indices, leaf hormone levels, and mineral element accumulation.

Regulatory Mechanism through Which Old Soybean Leaves Respond to Mn Toxicity Stress.

Manganese (Mn) is a heavy metal that can cause excessive Mn poisoning in plants, disrupting microstructural homeostasis and impairing growth and development. However, the specific response mechanisms of leaves to Mn poisoning have not been fully elucidated. This study revealed that Mn poisoning of soybean plants resulted in yellowing of old leaves.

Metabolic Responses to Manganese Toxicity in Soybean Roots and Leaves.

Soybean is one of the most crucial beans in the world. Although Mn (manganese) is a kind of important nutritive element helpful to plant growth and health, excess Mn is harmful to crops. Nevertheless, the effect of Mn toxicity on soybean roots and leaves metabolism is still not clear.

Transcriptome Sequencing Analysis of Root in Soybean Responding to Mn Poisoning.

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.
