“…The Pho-J1 isolate was grouped in the same cluster with a MN215621 sequence of Epicoccum sorghinum that was published before [15]. The Pho-J2 was grouped in the same cluster with sequence of MH368533, a Phoma matteucciicola of Curcuma wenyujin 5 [16] (figure 3). Therefore, we decided that Pho-J1 (LC721872) is identified as Epicoccum sorghinum, and Neoscirrhia matteucciicola (Syn.…”

Leaf spot disease is a serious constraint on ginger cultivation in Indonesia. The disease is primarily caused by certain fungal species. Another species of fungus that has never been reported before in Indonesia was consistently isolated from the collected samples of whitish spot symptom from Bogor and Sukabumi, West Java. The present study is aimed to determine the fungal identity and confirmed its pathogenicity as well as exploring its characteristics. Leaf tissue isolation, morphological characteristic observation and molecular analysis for determining the fungal identity, a pathogenicity test, disease occurrence observation on red- and white-ginger, colony characteristic on four different media and its response on PDA medium amanded with 0 – 500 ppm of mancozeb or copper hydroxide had been carried out in the plant pathology laboratory of ISMCRI in Bogor. The fungus was identified as a group of Phoma based on morphological characteristic, homology and phylogeny analysis. The carrot agar medium is the best medium for growing and sporulation of the fungus. The disease incidence and severity occurrence were more severe on white-ginger than the red-one. Mancozeb inhibited the fungus growth more effectively than copper hydroxide, but 500 ppm is not inhibiting the fungal growth.

“…Provenance Of The Virus Material P. matteucciicola strain HNQH1 was originally isolated from C. wenyujin, showing symptoms of leaf blight disease in Hainan, China, in 2018, and identi ed as P. matteucciicola based on morphological characteristics and phylogeny analysis [14]. The mycelia of HNQH1 were cultured for 7 days on cellophane membranes placed on top of potato dextrose agar (PDA) plates for dsRNA extraction.…”

Here, we report a novel mycotombus-like mycovirus, tentatively named 'Phoma matteucciicola RNA virus 2' (PmRV2), derived from the phytopathogenic fungus Phoma matteucciicola strain HNQH1. The complete PmRV2 genome is comprised of 3,460 nucleotides (nts), a positive-sense single-stranded RNA (+ ssRNA) with a GC content of 56.71%. Sequence analysis of PmRV2 indicated the presence of two noncontiguous open reading frames (ORFs) encoding a hypothetical protein and a RNA-dependent RNA polymerase (RdRp), respectively. PmRV2 contains a metal-binding 'GDN' triad in Motif C of RdRp while most + ssRNA mycoviruses contained a 'GDD' motif in the same region. Additionally, a BLASTp search showed that the RdRp amino acid sequence of PmRV2 was most closely related to the RdRp of Macrophomina phaseolina umbra-like virus 1 (50.72% identity) and Erysiphe necator umbra-like virus 2 (EnUlV2, 44.84% identity). Phylogenetic analysis indicated that PmRV2 grouped together with EnUlV2 within the recently proposed family of 'Mycotombusviridae'.

Here, a novel umbra-like mycovirus, ‘Phoma matteucciicola RNA virus 2’ (PmRV2), isolated from Phoma matteucciicola strain HNQH1 in Hainan province of China, was sequenced and analyzed. The complete genomic sequence of PmRV2 is 3,460 nucleotides (nts) with a GC content of 56.71%. Sequence analysis of PmRV2 indicated that the presence of two noncontiguous open reading frames (ORFs) encoding a hypothetical protein and a RNA-dependent RNA polymerase (RdRp), respectively. PmRV2 contains a metal-binding ‘GDN’ triad in Motif C of RdRp while most + ssRNA mycoviruses contained a ‘GDD’ motif in the same region.
