“…ET and SA are phytohormones that regulate plant growth and development and pathogen stress responses, among other activities (Bürger and Chory, 2019). Pretreatment of soybean seedlings from two soybean genotypes, one susceptible and one resistant to SDS infection, with an ET inducer before transplanting to F. virguliforme-infested soil reduced SDS foliar severity compared to the control (Abdelsamad et al, 2019). The ET inducer activated plant defence-associated genes and transcription factors and inhibited F. virguliforme mycelial growth.…”

Soybean sudden death syndrome: Fungal pathogenesis and plant response

Soybean (Glycine max) is a commercial crop mainly grown in the Americas and Asia. World production is about 348.7 million tonnes over 124.9 million ha in 2018 (last published data, Food and Agricultural Organization, http://www.fao.org/faost at/en/#data/QC, accessed on 18 March 2020). However, yield can be reduced by diseases and insect pests (Allen et al., 2017; Hartman et al., 2016). One important disease, sudden death syndrome (SDS), is caused by soilborne fungal pathogens that infect plants through the roots. These fungi are generally restricted to roots, but symptoms can be found both below and above ground. Root symptoms include necrosis and discoloration of the xylem. Aboveground symptoms include interveinal leaf chlorosis and necrosis (Hartman et al., 2015; Navi and Yang, 2016). These aboveground symptoms are caused by toxins produced by the pathogen in the roots that are translocated to the foliage (Hartman et al., 2015). Given the widespread interest in this soybean disease, as evidenced by the large number of articles published recently (more than 80 since 2015), here, we review experimental evidence on fungal pathogenesis, fungus-soybean interactions and plant disease resistance, symptom evaluation, and treatments, reported over the last five years. We have not covered genome mapping studies because this topic was the focus of recent reviews (Chang et al., 2018;
