“…Among these diseases, root rot is a severe and common disease caused by many pathogens, such as Fusarium spp., Alternaria alternata, and Cladosporium spp., and occurs under continuous cropping conditions [35]. As is reported, F. oxysporum diseases can cause significant reductions in the root yield, sugar content, and purity, and thus affect the sugar beet yield [36,37]. This pathogenic strain can remain in the soil for years, and traditional control methods are not always efficient [34].…”

The continuous cropping of sugar beet can result in soil degradation and a decrease in the sugar beet yield and quality. However, the role of continuous sugar beet (Beta vulgaris L. var. saccharifera) cropping in shaping the structure and function of the rhizosphere microbial community remains poorly investigated. In this study, we comparatively investigated the impact of different numbers of years of continuous sugar beet cropping on structural and functional changes in the microbial community of the rhizosphere using high-throughput sequencing and bioinformatics analysis. We collected rhizosphere soils from fields continuously cropped for one-year (T1), five-year (T5), and thirty-year (T30) periods, as well as one bulk soil (T0), in the Xinjiang Uygur Autonomous Region. The results demonstrated that continuous sugar beet cropping resulted in a significant decline in the community diversity of soil bacterial and fungal populations from T1 to T5. With continuous change in the structure of the microbial community, the Shannon diversity and observed species were increased in T30. With an abundance of pathogenic microbes, including Acidobacteria, Alternaria, and Fusarium, that were highly enriched in T30, soil-borne diseases could be accelerated, deduced by functional predictions based on 16S rRNA genes. Continuous sugar beet cropping also led to significant declines in beneficial bacteria, including Actinobacteria, Pseudomonas spp., and Bacillus spp. In addition, we profiled and analyzed predictive metabolic characteristics (metabolism and detoxification). The abundance of phenolic acid decarboxylase involved in the phenolic acid degradation pathway was significantly lower in groups T5 and T30 than that in T0 and T1, which could result in the phenolic compounds becoming excessive in long-term continuous cropping soil. Our results provide a deeper understanding of the rhizosphere soil microbial community's response to continuous sugar beet cropping, which is important in evaluating the sustainability of this agricultural practice.

“…F. oxysporum has been identified as the main cause of fusarium wilt disease in rice (Mironenko, 1960), tomato (Borisade et al, 2017), banana (Mostert et al, 2017), oil palm (Flood, 2006), sweet potato (Loebenstein and Thottappilly, 2009), eggplant (Miller et al, 2008), watermelon (Egel and Martyn, 2007), date palm (Elliot, 2009), and cabbage (Song et al, 1996). In addition, F. oxysporum has caused root rot disease in soybean (Arias et al, 2013;Ellis et al, 2014), sweet potato (Clark and Moyer, 1988), wheat (Labuschagne et al, 2010), sugar beet (Hanson et al, 2018), pepper (Cerkauskas, 2017), and Amaranthus hybridus (Chen and Swart, 2000). Moreover, Fusarium foetens, another closely related species of F. oxysporum, caused wilt disease in Begonia elatior in France (Saurat et al, 2013).…”

Fusarium commune associated with wilt and root rot disease in rice

Fusarium species are the world's most economically destructive and species-rich groups of mycotoxigenic plant pathogens (Aoki et al., 2014). Wilt and root rot disease, commonly known as fusarium wilt and root rot, has been caused by several species of Fusarium. Fusarium wilt is a common vascular fungal disease in plants, mainly caused by Fusarium oxysporum (Dita et al., 2018). However, Fusarium commune is also one of the causal pathogens of fusarium wilt and was originally misidentified as F. oxysporum, although it has been considered as a distinct species since 2003 (Yu and Babadoost, 2013). In China, F. commune was the most common cause of fusarium wilt in Eleochari dulcis (Zhu et al., 2014). This pathogen has been isolated from soil and plants including white pine, Douglas-fir, carnation, maize, carrot, and barley (Skovgaard

Suppression of Fusarium oxysporum with recombinant polygalacturonase inhibiting proteins (BvPGIPs) extracted from sugar beet roots

Soil-borne fungus Fusarium oxysporum f. sp. betae (Fob) is the causative agent of Fusarium yellows in sugar beet. Leaf interveinal yellowing and root vascular discoloration significantly reduce root yield as well as sucrose content and juice purity. Fob, like other fungal pathogens, initiates disease development by secreting polygalacturonase (PG) enzymes to break down plant cell walls during early stages of infection. To protect themselves, plants produce polygalacturonase-inhibiting proteins (PGIPs). In our study of sugar beet root defense responses, several PGIP genes (BvPGIPs) were identified. To determine if BvPGIPs inhibit Fob PGs, genes BvPGIP1, BvPGIP2 and Bv(FC607)PGIP1 were fused with the CaMV 35S promoter and each was expressed individually in sugar beet hairy roots. We demonstrate that all three recombinant BvPGIP proteins inhibited Fob and F. oxysporum f. sp. gladioli (Fog) PGs. A comparable level of BvPGIP activity was observed against Fob PGs, while BvPGIP2 showed higher activity against Fog PGs. Similar results were obtained when recombinant PGIPs were used to bioassay effects on Fob and Fog spore germination and hyphal growth. This is a first report that documents F. oxysporum inhibition by overexpressing BvPGIPs that may lead to improved Fusarium yellows resistance in sugar beet.
