“…Species of Nigrospora are a cosmopolitan in their distribution and frequently occur as plant pathogens, endophytes or saprobes (Cui et al 2018;Raza et al 2019). Several species of Nigrospora have been reported as leaf spot-inducing fungi, including N. sphaerica in cladode in Brazil (Conforto et al 2019), date palms (Alam et al 2019) and mandarin (Alam et al 2017a) in Pakistan, and mulberry in India (Arunakumar et al 2019), and N. oryzae on watermelon, Kiwifruit and lotus in China (Alam et al 2017b;Li et al 2018;Zhang et al 2018) and Aloe in Bangladesh and Pakistan (Alam et al 2017b;Begum et al 2018).…”

Date palm is the most important crop in Oman, occupying approximately 50% of the area devoted to agriculture. Little information is available on leaf spot diseases of date palm in Oman and in the world. This study was conducted to identify the most common fungal pathogens associated with leaf spot diseases of date palm. A total of 198 symptomatic leaf samples were collected from seven districts in Oman. Isolations revealed that most isolates belonged to the genus Alternaria. Molecular-based identification using multigene sequences revealed that the isolates belonged to Alternaria alternata, A. burnsii, A. tomato, Curvularia subpapendorfii, Didymella microchlamydospora, Fusarium brachygibbosum, F. incarnatum-equiseti and Nigrospora lacticolonia. In pathogenicity tests, A. alternata was found to be the most aggressive. F. incarnatum-equiseti was the least aggressive, only inducing symptoms in leaves injured prior to inoculation. The other species caused moderate leaf spot symptoms on the leaves. This study shows that several fungal species belonging to different genera can be found associated with leaf spot symptoms of date palms, and they vary in their aggressiveness on date palm leaves. It is the first study to report C. verruculosa, D. microchlamydospora, and N. lacticolonia as leaf spot pathogens of date palm in the world.

“…Two weeks after inoculation, symptoms were observed only on the leaves inoculated with conidia and the fungus was consistently re-isolated. Nigrospora sphaerica was observed on blueberry in Argentina, sugarcane in China, and tea in India (Cui et al 2018;Dutta et al 2015). To our knowledge, this is the first report of N. sphaerica on peanut.…”

“…Among the species reported by the authors were N. aurantiaca, N. camelliae-sinensis, N. hainanensis, N. lacticolonia, N. pyriformis, N. sphaerica, N. zimmermanii, N. falsivesicularis, N. vesicularifera, N. saccharicola, N. sacchari-officinarum, and N. singularis. Another study, also conducted in China, reported N. sphaerica as the causing agent of leaf blight in sugarcane [75].…”

Dark septate endophytes (DSEs) constitute a polyphyletic group within the Ascomycota, with global distribution and a wide range of host plant species. The present study evaluated the diversity of DSE in sugarcane roots of the varieties RB867515, RB966928, and RB92579, and four varieties of not commercialized energy cane. A total of 16 DSE strains were isolated, mostly from the varieties RB966928 and RB867515, with six and five isolates, respectively. Just one of the four energy cane varieties had fungi with DSE appearance. The analyses of the DNA sequences from the internal transcribed spacer (ITS) and the large subunit (LSU), in association with the micromorphology of the isolates, allowed the differentiation of the 16 isolates in at least five species, within the families Periconiaceae, Pleosporaceae, Lentitheciaceae, Vibrisseaceae, and Apiosporaceae and the orders Pleosporales, Helotiales, and Xylariales. The order Pleosporales represented 80% of the isolates, and the species Periconia macrospinosa, with six isolates, accounted for the highest isolation frequency. The results confirm the natural occurrence of the DSE symbiosis in sugarcane varieties and the generalist character of these fungi as some of the detected species have already been reported associated with other host plants, ecosystems, and regions of the world.
