“…E. rostratum is a plant pathogen with a wide range of hosts and has a high impact on grasses and Poaceae [ 48 , 49 ] and was first identified in rice in Venezuela [ 50 ]. Researchers in Algeria have found that E. rostratum is more invasive to maize than Bipolaris sorokiniana in pathogenicity tests of E. rostratum and B. sorokiniana [ 51 ]. In humans, the fungus has mainly caused keratitis and skin diseases [ 8 , 52 ].…”

Rice spikelet rot disease occurs mainly in the late stages of rice growth. Pathogenicity and biological characteristics of the pathogenic fungus and the infestation site have been the primary focus of research on the disease. To learn more about the disease, we performed whole-genome sequencing of Exserohilum rostratum and Bipolaris zeicola for predicting potentially pathogenic genes. The fungus B. zeicola was only recently identified in rice.We obtained 16 and 15 scaffolds down to the chromosome level for E. rostratum LWI and B. zeicola LWII, respectively. The length of LWI strain was approximately 34.05 Mb, and the G + C content of the whole genome was 50.56%. The length of the LWII strain was approximately 32.21 Mb, and the G + C content of the whole genome was 50.66%. After the prediction and annotation of E. rostratum LWI and B. zeicola LWII, we predicted that the LWI strain and LWII strain contain 8 and 13 potential pathogenic genes, respectively, which may be related to rice infection. These results improve our understanding of the genomes of E. rostratum and B. zeicola and update the genomic databases of these two species. It benefits subsequent studies on the mechanisms of E. rostratum and B. zeicola interactions with rice and helps to develop efficient control measures against rice spikelet rot disease.

“…Bipolaris sorokiniana is a plurivorous species, and has been reported as a phytopathogen of almost a hundred Poaceae, including cultivated and wild species (Farr and Rossman, 2022), and from different countries (Karunarathna et al, 2021). In Algeria, B. sorokiniana has been isolated from leaves of lentil (El Amine et al, 2021) and maize (Zibani et al, 2022).…”

Symptoms of foliar blight were observed on turfgrass in Oran (Algeria), including yellow chlorotic patches on leaves during the 2020 summer (temperatures between 35 and 40°C). Symptoms extended downward from leaf tips and entire leaves became blighted, leading to irregular discoloured areas that later turned brown. Isolations from infected plants included 214 isolates identified as Curvularia or Bipolaris, based on morphological traits. Other isolates included Fusarium, Myrothecium and Acremonium spp. Three molecular loci, ITS rDNA, gpd and tef1, were amplified and sequenced. Morphological and multi-locus phylogenetic analyses revealed four fungal species viz. B. sorokiniana, C. spicifera, C. verruculosa, C. geniculata, and two additional Curvularia lineages, some of these fungi are reported are first records for Algeria. Koch’s postulates were confirmed by inoculating potted turfgrass with spore suspensions of 16 isolates and re-isolating of the inoculated pathogens from symptomatic tissues. Bipolaris sorokiniana was the most virulent pathogen causing numerous foliar necrotic lesions similar to those observed in the field. Other isolates infected basal leaves only, and caused less severe symptoms. The results show that Curvularia species may be secondary pathogens infecting stressed plants, and that simultaneous occurrence of high temperatures and poor water quality have influenced disease progression. Correct identification of these pathogens is important for applying appropriate and timely disease management.
