A Correction on
Mitigation mechanism of silicon and iron co-application to cadmium toxicity in tomato seedlings by integrated transcriptomic and physiological correlation analysis

By Zhou X, Wang W, Ye D, Liu X, Peng C, Tang Y, Su L, Cheng S, Cao K, Lei Q, Pan T and He Z (2025) Front. Plant Sci. 16:1555618. doi: 10.3389/fpls.2025.1555618

There was a mistake in the caption of Figure 12 as published. Figure 12 caption should not include “WGCNA analysis”. The corrected caption of Figure 12 appears below.

Figure 12
Heatmap showing gene expression levels across different samples labeled CKY, CdY, CSY, CFY, and CSFY. The color gradient from blue to red indicates values from -2 to 2. Genes are categorized into groups: ACA, ZIP, MGT, SULTR, VIT, and YSL, with associated IDs.

Figure 12. DEGs involving element transporters in tomato seedlings. ACA (Ca), ZIP (Zn/Fe), MGT (Mg), SULTR (SO42-), VIT and YSL (Fe). Color indicates the expression level: the redder the color, the higher the number of DEGs.

A correction has been made to the section 3.5.4 DEGs involving glutathione. The citation of “Figure 9” was missing from “Conversely, the expression of these genes showed an opposite trend in CS and CF compared to that in Cd and was significantly upregulated in CSF.” The correct phrase appears below:

“Conversely, the expression of these genes showed an opposite trend in CS and CF compared to that in Cd and was significantly upregulated in CSF (Figure 9).”

A correction has been made to the section 3.5.5 DEGs involving element transporters. The citation of Figure 12 was missing from: “In this experiment, Cd exposure upregulated genes encoding ACA, ZIP, MGT, SULTR, VIT, and YSL, while CSF treatment significantly downregulated these genes.” The correct phrase appears below:

“In this experiment, Cd exposure upregulated genes encoding ACA, ZIP, MGT, SULTR, VIT, and YSL, while CSF treatment significantly downregulated these genes (Figure 12).”

In the published article, there was an error in 3.8 Model sketch as published. Figure 13 and its citation disappeared from under the text “These mechanisms collectively contribute to the protection of tomato seedlings against Cd stress”. The corrected Figure 13, its citation and its caption appear below:

Figure 13
Diagram illustrating the process of cadmium tolerance in plants. Cadmium (Cd²⁺) and iron (Fe³⁺) uptake are shown, with silicon (Si) playing a role in reducing Cd²⁺ assimilation. Inside the cell, various pathways are depicted including photosynthesis and carbon metabolism. Transcription factors (TFs), superoxide dismutase (SOD), and other enzymes like POD, CAT, and GS are involved in detoxifying reactive oxygen species such as superoxide (O₂⁻) and hydrogen peroxide (H₂O₂), ultimately contributing to cadmium tolerance. The diagram emphasizes the interactions between elements and molecular responses.

“These mechanisms collectively contribute to the protection of tomato seedlings against Cd stress (Figure 13)”.
