“…Fs has been reported to be transmitted by air currents and easily dispersed by rain splash ( Nordahliawate et al, 2008 ), and it has also been reported to cause leaf diseases on Rhynchostylis gigantea ( Dekham and Kanchanawatee, 2020 ) and sugarcane ( Yao et al, 2020 ). It has also been reported to cause wilt on sugarcane ( Viswanathan et al, 2017 ; Bao et al, 2020 ), indicating it has the potential to become a soil-borne disease. A most notorious soil-borne banana pathogen is Foc , which first invades the roots and then climbs up the pseudo-stems through the vessels of the plant’s vascular system ( Czislowski et al, 2018 ).…”

Fusarium species have been identified as pathogens causing many different plant diseases, and here we report an emerging banana leaf blight (BLB) caused by F. sacchari (Fs) discovered in Guangdong, China. From the symptomatic tissues collected in the field, a fungal isolate was obtained, which induced similar symptoms on healthy banana seedlings after inoculation. Koch’s postulates were fulfilled after the re-isolation of the pathogen. Phylogenetic analysis on two gene segments and the whole genome sequence identified the pathogen belonging to Fs and named as Fs str. FS66. A 45.74 Mb genome of FS66 was acquired through de novo assembly using long-read sequencing data, and its contig N50 (1.97 Mb) is more than 10-fold larger than the previously available genome in the species. Based on transcriptome sequencing and ab initio gene annotation, a total of 14,486 protein-encoding genes and 418 non-coding RNAs were predicted. A total of 48 metabolite biosynthetic gene clusters including the fusaric acid biosynthesis gene cluster were predicted in silico in the FS66 genome. Comparison between FS66 and other 11 Fusarium genomes identified tens to hundreds of genes specifically gained and lost in FS66, including some previously correlated with Fusarium pathogenicity. The FS66 genome also harbors widespread gene transfer on the core chromosomes putatively from F. oxysporum species complex (FOSC), including 30 involved in Fusarium pathogenicity/virulence. This study not only reports the BLB caused by Fs, but also provides important information and clues for further understanding of the genome evolution among pathogenic Fusarium species.

“…Pokkah boeng disease (PBD) is an airborne fungal disease caused by Fusarium fujikuroi species complex (FFSC) and is responsible for severe yield losses in susceptible varieties of sugarcane worldwide. The FFSC species F. sacchari is associated with both PBD and sugarcane wilting (Viswanathan et al, 2017) as well as fruit rot disease in bananas (Abd Murad et al, 2017), spear rot of oil palm (Suwandi et al, 2018), and even mycotic keratitis among sugarcane farmers (Bansal et al, 2016). The FFSC species F. andiyazi has been reported to cause wheat head blight (Wang et al, 2015), ear rot of maize (Bandara et al, 2017), and stalk rot of sorghum (Zhang et al, 2014).…”

Frontiers in Microbiology | www.frontiersin.org February 2020 | Volume 11 | Article 240 Yao et al. Virome Identification and Characterization of Fusarium spp.was observed and the characterization of the four-segment dsRNA chrysovirus was performed with aid of electron microscopy and analysis of the encapsidated RNAs. These findings provide insight into the diversity and spectrum of mycoviruses in PBD pathogens and should be useful for exploring agents to control the disease.

“…Fusarium sacchari is an economically important plant pathogen of sorghum (Leslie et al, 2005), wheat (Wang et al, 2014), maize (Hsuan et al, 2011;Leslie et al, 2005), banana (Tarnowski et al, 2010), rice (Hsuan et al, 2011;Petrovic et al, 2013) and sugarcane (Egan et al, 1997;Hsuan et al, 2011;Poongothai et al, 2014;Viswanathan et al, 2017;. In the present study, F. sacchari was isolated from R. gigantea leaves with yellow leaf spot disease, adding R. gigantea orchids to the host list of F. sacchari.…”

Yellow leaf spot disease was observed on Rhynchostylis gigantea orchids on an orchid farm in the Nonthaburi province of Thailand. Symptoms started with yellowish patches lacking definitive borders on the leaves of the orchids. The patches slowly expanded and merged, creating larger patches; a brown spot or black necrotic area then emerged at the center of some of the patches. R. gigantea leaves exhibiting these symptoms were used as the source for isolation studies. Based on the morphological characteristics of the fungal isolate (colony appearance, macroconidia, microconidia, conidiophore and chlamydospore structures), phylogenetic analysis of translation elongation factor-1α sequence and fulfillment of Koch's postulates, the causative pathogen was identified as Fusarium sacchari. To our knowledge, this study is the first to report F. sacchari as a pathogen of R. gigantea.
