“…Interestingly, that infection by T. caries or Fusarium of the resistant forms of wheat-activated isoperoxidases which can sorb on pathogen mycelium or chitin (Khairullin et al 2000;Caruso et al 2001). Furthermore, these isoperoxidases possessed antifungal activity (Caruso et al 2001;Akhunov et al 2008).…”

The role of salicylic acid (SA) in regulating wheat calli growth and peroxidase activity in the co-culture with bunt (Tilletia caries (D.C.) Tul.) and smut (Ustilago tritici Pers.) pathogens was studied in this work. We found that the influence of SA increased the number of globular high-density sites with meristema-like cells and reduced the number of low-structured sites with parenchyma-like cells in wheat calli. SA inhibited fungi spores germination, mycelium growth, and formation of its new spores during the co-cultivation of wheat calli with bunt or smut agent. Interaction of fungi mycelium with wheat calli treated by SA led to formation of zones with hypersensitive reaction in calli high-structured sites with meristema-like cells. The obtained data about the influence of SA on activation of wheat calli growth and the peroxidases with pI Â3.5 and Â9.8, which can bind to the mycelium of T. caries or U. tritici are discussed in this paper.

“…4), Septoria nodorum (Yusupova et al, 2006) and Tilletia caries (Khairullin et al, 2000); in potato infected by Phytophthora infestans (Maksimov et al, 2011), and in Aegilops umbellulata infected by Septoria nodorum . Akhunov et al (2008) purified chitin-specific PO with fungicidal activity from cotton and observed the increase of its activity in plants, penetrated by Verticillium dahliae. Golubenco et al (2007) showed the presence of the chitin-binding PO isozyme in Hibiscus trionum, which activated dramatically after inoculation by V. dahliae.…”

“…Furthermore, many kinds of transcription factors, protein kinases, and phytohormones are involved during the response process of cotton plants to Fov: for example, the cotton MAPK kinase GhMPK20 negatively regulates resistance to F. oxysporum, and the expression of GhMKK6 contributes to the immune response in cotton (Wang et al 2018;Wang et al 2017). Notably, both salicylic acid and jasmonic acid can contribute to the over-expression of pathogenesis-related genes in cotton plants (Akhunov et al 2008).…”

Fusarium wilt, caused by the fungus Fusarium oxysporum Schlecht. f. sp. vasinfectum (Fov) is a destructive soil-borne cotton disease. To profile the genes and pathways responding to Fov infection, we compared transcriptomic responses before and after F. oxysporum inoculation in a highly resistant cotton cultivar, Yumian21, and a highly susceptible cultivar, Jimian11. Although the overall gene expression pattern was downregulated in both cultivars, the global gene expression in the resistant cultivar was stronger than that in the susceptible cultivar. In addition, the expressed genes of two cultivars mostly differed in “cellular process,” “single-organism process,” “metabolic process,” and “response to stimulus” functional groups in the biological process Gene Ontology category: the upregulated differentially expressed genes (DEG) were largely enriched in the resistant cultivar, while the downregulated DEGs were largely enriched in the susceptible cultivar. Phenylpropanoid biosynthesis and phenylalanine metabolism are the key metabolic pathways in cotton in response to Fov. We found that lignin plays a potential role in cotton resistance to Fov. Two coding genes, caffeic acid 3-O-methyltransferase and peroxidase2, as well as the two transcription factors MYB46 and MYB86, are possibly involved in the accumulation and synthesis of lignin. Furthermore, the result showed that the quantification of lignin could be potentially used as a selection tool to identify Fusarium wilt resistant cotton.
