Article Title: Two Subunits of the Rpd3 Histone Deacetylase Complex of Cochliobolus heterostrophus Are Essential for Nitrosative Stress Response and Virulence, and Interact With Stress‐Response Regulators ChHog1 and ChCrz1

Figure Lengend Snippet: ChHog1 interacted with ChCrz1 to modulate the nitrosative stress response in Cochliobolus heterostrophus . (a) Yeast two‐hybrid assay validation of the interaction between ChHog1 and ChCrz1. (b) The interaction between ChHog1 and ChCrz1 was verified by glutathione S‐transferase (GST) pull‐down assay. (c) The expression of ChCRZ1 was induced by sodium nitroprusside (SNP) treatment, and ChCrz1 regulated the transcription of ChGSNOR and ChFHB in response to nitrosative stress in C. heterostrophus . (d) The expression of ChPHO23 was induced by SNP treatment, and the expression of detoxification genes was changed in Δ Chpho23 mutant compared to wild type (WT). (e) The expression of ChHOG1 was not induced by SNP treatment, but the expression of detoxification genes was changed in Δ Chhog1 mutant compared to WT. Each strain was cultured in complete medium with xylose (CMX) for 30 h and then transferred to CMX without or with 10 mM SNP for 2 h. The ChACTIN gene was used as an internal control. GraphPad Prism program's t tests and multiple t tests were used for the analysis of significant differences. The bars indicate SEM of three replications. ** in (c) indicates significant differences based on t test ( p < 0.01).
Article Snippet: The wild‐type strain C. heterostrophus C4 ( Tox1 + , MAT1‐2 , ATCC 48331) was used as the parental strain.
