“…The above evidence demonstrates that toxins produced by F. virguliforme in colonized roots translocate to the leaves and cause leaf senescence and chlorophyll degradation (Brar et al, 2011; Bhattacharyya, 2012; Pudake et al, 2013). However, much less is tucumaniae homogeneously mixed in the soil, compared with the uninoculated control (Rosati et al, 2018), and in leaf disks from a susceptible soybean cultivar infiltrated with the recombinant FvTox1 from F. virguliforme compared with the control (Brar et al, 2011). This chlorophyll degradation by F. virguliforme toxins is associated with soybean STAY GREEN genes (Chang et al, 2019).…”

Sudden death syndrome (SDS) of soybean is a fungal disease caused by at least four distinct Fusarium species: F. tucumaniae, F. virguliforme, F. brasiliense, and F. crassistipitatum. All four species are present in Argentina. These fungi are soilborne pathogens that only colonize roots and cause root necrosis. However, damage also reaches the aboveground part of the plant, and foliar chlorosis and necrosis, followed by premature defoliation, can be observed. Although the pathogenicity and phytotoxicity of F. virguliforme has been well characterized, knowledge regarding disease development by other fungal species is scarce. In this study, two plant species, soybean (Glycine max) and Arabidopsis thaliana, and isolates from two fungal species, F. tucumaniae and F. crassistipitatum, were used to comparatively analyse the fungal pathogenicity and the phytotoxicity of volatile organic compounds (VOCs) and cell‐free culture filtrates. Fungal inoculation had a significant effect on plant growth, regardless of the plant species. In addition, infected soybean plants showed disease incidence and foliar and root symptoms. Inhibition of A. thaliana growth was not due to VOCs emitted by fungi. Instead, both pathogens were shown to produce toxins that caused typical SDS foliar symptoms in soybean and root length reduction in A. thaliana. As far as we know, this is the first report that demonstrates that F. tucumaniae and F. crassistipitatum affect A. thaliana growth and emit VOCs, and that F. crassistipitatum produces toxins.

“…Most of these proteins are involved in disease resistance and/ or the stress response of the partially resistant plants or in metabolic regulation of the partially susceptible plants (Iqbal et al, 2016). The metabolomes of roots and leaves from susceptible and partially resistant soybean cultivars inoculated with F. tucumaniae were also analysed by gas chromatography-mass spectrometry (GC-MS) (Scandiani et al, 2015;Rosati et al, 2018). Results indicated that the pathogen induced an accumulation of amino acids in roots (Scandiani et al, 2015) and leaves (Rosati et al, 2018) of the susceptible cultivar during early stages of infection (starting at 7 and 10 days after inoculation for root and leaf tissues, respectively).…”

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;

“…Among them, a 13.5 kDa protein named Fvtox1 causes interveinal chlorosis and necrosis in leaves of susceptible soybean varieties 24,27 . Interestingly, foliar SDS‐like symptoms development requires light, which suggests that FvTox1 alters the photosynthetic process 24,28 . In addition, toxin‐associated symptoms are affected by other environmental conditions such as temperature and media substrate 29–31 and, consequently, environmental changes over the years can explain the appearance of various degrees of foliar symptoms in the field 5,32 .…”

The increase in food production requires reduction of the damage caused by plant pathogens, minimizing the environmental impact of management practices. Soil‐borne pathogens are among the most relevant pathogens that affect soybean crop yield. Soybean sudden death syndrome (SDS), caused by several distinct species of Fusarium, produces significant yield losses in the leading soybean‐producing countries in North and South America. Current management strategies for SDS are scarce since there are no highly resistant cultivars and only a few fungicide seed treatments are available. Because of this, innovative approaches for SDS management need to be developed. Here, we summarize recently explored strategies based on plant nutrition, biological control, priming of plant defenses, host‐induced gene silencing, and the development of new SDS‐resistance cultivars using precision breeding techniques. Finally, sustainable management of SDS should also consider cultural control practices with minimal environmental impact. © 2021 Society of Chemical Industry.
