Transcriptome analyses of L. fusiformis Cr33-inoculated roots in response to Cd stress. (A) Three-week-old tomato plants cultured in the split-root systems were inoculated with or without Cr33 for 3 d. Then, these plants were exposed to 100 μM Cd with or without Cr33 for 48 h. Total RNA samples extracted from the treated roots were used for RNA-Seq analyses, including Group I (Cd48 vs. –Cd) and II (Cr33 + Cd48 vs. Cd48). (B) Numbers of DEGs in both Group I and II. (C) Venna diagram of shared and specific DEGS between the Group I and II. (D,E) KEGG analyses for up-regulated DEGs from the Group I and II. (F) A model for the Cd-activated Fe uptake leading to aggravate Cd toxicity in plants. Cd-induced expression of Fe uptake-related genes including FIT (a functional homolog of Fer), IRT1, and FRO2 resulted in the increased Cd uptake in plants. (G) Expression profiles of Fer, IRT1, and FRO1 in both the Group I and II.
