“…Expression levels of the SA pathway marker genes PR1, PR2, and PR5 and the JA/ET signaling marker genes PLANT DEFENSIN1.2 (PDF1.2), PR4, and BASIC CHITINASE (ChiB) in the samples were examined by real-time quantitative PCR. [5][6][7][8] Confirming the previous results, 1 NADP addition significantly induced the SA pathway marker genes (Fig. 1A).…”

“…As a reference condition we used A. thaliana seedlings incubated without fungal spores. After the isolation of RNA from leaves harvested after 96 and 120 h, we performed transcript analysis of A. thaliana genes that are considered markers of SA-dependent systemic acquired resistance (PR-1a, PR-2, and PR-5 [38,39]) or markers of the JA/ET-dependent defense of plants (PR-3, PR-4, and PDF1.2 [40]). In A. thaliana seedlings inoculated with the T. atroviride parental strain, the SAR-related genes were induced during the earlier period, and later their transcript levels dropped close to those observed for the reference condition (without fungal spores) (Fig.…”

bAs a result of a transcriptome-wide analysis of the ascomycete Trichoderma atroviride, mycoparasitism-related genes were identified; of these, 13 genes were further investigated for differential expression. In silico analysis of the upstream regulatory regions of these genes pointed to xylanase regulator 1 (Xyr1) as a putatively involved regulatory protein. Transcript analysis of the xyr1 gene of T. atroviride in confrontation with other fungi allowed us to determine that xyr1 levels increased during mycoparasitism. To gain knowledge about the precise role of Xyr1 in the mycoparasitic process, the corresponding gene was deleted from the T. atroviride genome. This resulted in strong reductions in the transcript levels of axe1 and swo1, which encode accessory cell wall-degrading enzymes considered relevant for mycoparasitism. We also analyzed the role of Xyr1 in the Trichoderma-Arabidopsis interaction, finding that the plant response elicited by T. atroviride is delayed if Xyr1 is missing in the fungus.

Fusarium graminearum ATP-Binding Cassette Transporter Gene FgABCC9 Is Required for Its Transportation of Salicylic Acid, Fungicide Resistance, Mycelial Growth and Pathogenicity towards Wheat

ATP-binding cassette (ABC) transporters hydrolyze ATP to transport a wide range of substrates. Fusarium graminearum is a major causal agent of Fusarium head blight, which is a severe disease in wheat worldwide. FgABCC9 (FG05_07325) encodes an ABC-C (ABC transporter family C) transporter in F. graminearum, which was highly expressed during the infection in wheat and was up-regulated by the plant defense hormone salicylic acid (SA) and the fungicide tebuconazole. The predicted tertiary structure of the FgABCC9 protein was consistent with the schematic of the ABC exporter. Deletion of FgABCC9 resulted in decreased mycelial growth, increased sensitivity to SA and tebuconazole, reduced accumulation of deoxynivalenol (DON), and less pathogenicity towards wheat. Re-introduction of a functional FgABCC9 gene into ΔFgABCC9 recovered the phenotypes of the wild type strain. Transgenic expression of FgABCC9 in Arabidopsis thaliana increased the accumulation of SA in its leaves without activating SA signaling, which suggests that FgABCC9 functions as an SA exporter. Taken together, FgABCC9 encodes an ABC exporter, which is critical for fungal exportation of SA, response to tebuconazole, mycelial growth, and pathogenicity towards wheat.
