“…PBD, caused by Fusarium spp., is one of the main sugarcane diseases in the world [10,18]. In PBD, the fungal conidia can be spread via wind; therefore, new leaves are easily infected under high temperature, humidity, and rainfall conditions [35]. Chemical fungicides used against PBD cannot penetrate into the waxy layer of sugarcane stems; however, they exhibit adverse effects on the environment and human health [20].…”

Background Endophytes are reported to play a role in resistance against plant pathogens. Understanding the metabolite-mediated endophytic microbiota composition in plants provides insights to improve plant stress resistance. In this study, via metabolome and microbiome analyses, we aimed to elucidate the resistance mechanism of sugarcane cultivars with high resistance to sugarcane pokkah boeng disease (PBD). The endophytic microbial composition and metabolites in the stems of various sugarcane cultivars with high resistance (HR) or high susceptibility (HS) to PBD were analyzed. Results The results revealed that the endophytic fungi with biocontrol effects such as Shinella, Dechloromonas, and Microbacter were significantly enriched, and the abundance of pathogenic fungi such as Fusarium, Ramichloridium, Scleroramularia, Phaeosphaeriopsis, Sarocladium, Zygophiala, Gibberella, Pseudocercospora, Cyphellophora, Monocillium, Apiotrichum, Microsphaeropsis, and Scleroramularia significantly reduced in the stems of HR cultivars. Additionally, six metabolites [citric acid, isocitrate, malic acid, PC(16:0/0:0), phosphocholine, and lysoPC(16:0)] were significantly related to the endophytes in the stems of HR cultivars. Conclusions These results suggested that more abundance of antagonistic microbes and highly active metabolic functions of endophytes in the HR cultivars were the important mechanisms underlying their higher resistance to PBD.

“…The earliest symptom of PBD is chlorosis towards the base of the young leaves and occasionally on the other parts of the leaf blades. Severe sugarcane PBD frequently occurs in high temperatures and humidity (Vipul et al, 2018). Fusarium pathogens of PBD grow and sporulate luxuriantly in a temperature range of 20-30°C and a humidity range of 75%-85% (Kumar et al, 2011).…”

“…Sugarcane pokkah boeng disease (PBD) is caused by a Fusarium species complex (FSC; Bao et al, 2016; Costa et al, 2019; Nordahliawate et al, 2008). PBD spreads to new leaves by wind dispersal of conidia (Martin et al, 1989; Sidique, 2007) and infection is favoured by high temperature (25–32°C), humidity (80%–85%) and rainfall (300–400 mm) (Vipul et al, 2018). PBD was first discovered in Java in 1896 and subsequently spread worldwide with the production and cultivation of POJ2878 (Martin et al, 1989; Sidique et al, 2008).…”

Sugarcane pokkah boeng disease (PBD), caused by a Fusarium species complex, is one of the most critical diseases causing a significant economic loss of sugarcane production in China. It is important to standardize the evaluation method for screening sugarcane cultivars for resistance to PBD. Field trials were conducted to investigate the occurrence of sugarcane PBD in different months and growth stages from 2018 to 2019 and to evaluate the PBD resistance of 169 sugarcane genotypes from 2019 to 2022. PBD mainly occurred in the early and middle elongation stages at a plant height of approximately 1-2 m. The most severe and common incidence of PBD was from June to August. Variance analysis showed genotype, year and the interaction of genotype and year had a significant effect on disease incidence and disease index.The 169 sugarcane genotypes were divided into five categories by cluster analysis and discriminant analysis, of which 33 were rated as highly resistant, 37 as resistant, 38 as moderately susceptible, 26 as susceptible and 35 as highly susceptible. These findings enhance our understanding of sugarcane resistance to PBD and lay the foundation for breeding new resistant varieties.
