“…Although B. zeicola is primarily pathogenic to maize, B. zeicola is also pathogenic to other gramineous crops. B. zeicola was first found to be pathogenic to barley in Argentina, and the symptoms were similar to those of B. zeicola to maize [ 61 ]. Egyptian researchers have found that B. zeicola can cause wilting, severe rot, and death in rice seedlings [ 62 ].…”

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.

“…For inoculation, a 10 ml conidial suspension was prepared separately from 10 days old pure cultures for each isolate (Table 1) by scraping pathogen colonies from the agar surface with a sterile spatula and sterile water, and the conidial solution was adjusted to 10 6 spores/ml. (Cipollone et al., 2020). Using an electric fine atomizer, the inoculum of corresponding isolates was sprayed equally on the foliage of 15‐day‐old browntop millet seedlings.…”

A new leaf blight disease of browntop millet (Brachiaria ramosa) was noticed during rainy season (Kharif) 2018 at small millet experimental field, University of Agricultural Sciences, Gandhi Krishi Vignana Kendra (GKVK), Bengaluru, India. To assess the disease severity, an intensive roving survey was conducted during the 2019 cropping season. Based on the morphological characterization, the causal agent of leaf blight disease was identified as Bipolaris spp. Further sequencing and combined gene analysis of ITS (internal transcribed spacer of rDNA), GAPDH (glyceraldehyde 3‐phosphate dehydrogenase) and LSU (large subunit) of all the nine isolates confirmed the pathogen as B. setariae. Pathogenicity study showed that all the isolates were pathogenic and caused leaf blight symptoms on browntop millet. The B. setariae isolates showed marked variability with respect to disease incidence on browntop millet (cv. Dundu korale) under artificial inoculation conditions. However, the host range was limited only to browntop millet and found non‐pathogenic to other six small millets examined. To our knowledge, this is the first completely described study on characterization of B. setariae causing leaf blight disease of browntop millet in India.
