“…It is widely known that R. solani AG-3 PT is the main and the most aggressive causal agent of stem canker or black scurf on potatoes [ 35 , 36 , 37 , 38 , 39 ]. In addition to AG-3 PT, AG-1, AG-2, AG-4, AG-5, AG-6, AG-7, AG-8, AG-9, AG-10, AG-11, AG-12, and AG-13 were also reported to cause Rhizoctonia disease on potato [ 35 , 36 , 39 , 40 , 41 , 42 , 43 , 44 , 45 ]. In addition, BNR, used to protect potatoes against MNR previously [ 46 , 47 ], was proven to cause slight symptoms of stem canker on potatoes, such as AG-A, AG-F, AG-G, AG-I, AG-K, AG-U, and AG-W [ 48 , 49 , 50 , 51 , 52 ].…”

In this study, the diversity of putative mycoviruses present in 66 strains of binucleate Rhizoctonia (BNR, including anastomosis group (AG)-A, AG-Fa, AG-K, and AG-W) and 192 strains of multinucleate Rhizoctonia (MNR, including AG-1-IA, AG-2-1, AG-3 PT, AG-4HGI, AG-4HGII, AG-4HGIII, and AG-5), which are the causal agents of potato stem canker or black scurf, was studied using metatranscriptome sequencing. The number of contigs related to mycoviruses identified from BNR and MNR was 173 and 485, respectively. On average, each strain of BNR accommodated 2.62 putative mycoviruses, while each strain of MNR accommodated 2.53 putative mycoviruses. Putative mycoviruses detected in both BNR and MNR contained positive single-stranded RNA (+ssRNA), double-stranded RNA (dsRNA), and negative single-stranded RNA (-ssRNA) genomes, with +ssRNA genome being the prevalent nucleic acid type (82.08% in BNR and 75.46% in MNR). Except for 3 unclassified, 170 putative mycoviruses found in BNR belonged to 13 families; excluding 33 unclassified, 452 putative mycoviruses found in MNR belonged to 19 families. Through genome organization, multiple alignments, and phylogenetic analyses, 4 new parititviruses, 39 novel mitoviruses, and 4 new hypoviruses with nearly whole genome were detected in the 258 strains of BNR and MNR.

“…Onderzoek heeft uitgewezen dat verschillende Rhizoctonia-isolaten (behorende tot AG 1-1B, AG 1-1C, AG 2-1, AG 2-1 subset Nt, AG 3, AG 4 HGII, AG 5 en AG K) aanwezig zijn in Belgische bloemkoolakkers, maar dat isolaten behorende tot AG 2-1 domineren (Pannecoucque et al, 2008). Anderzijds kunnen isolaten behorende bij AG 2-1 ook bij andere gewassen schade geven, zoals tarwe en koolzaad (Sturrock et al, 2015;Jaaffar et al, 2016), sla (van Beneden et al, 2009b), aardappel (Murdock et al, 2019) of van andere gewassen geïsoleerd worden (bv. suikerbiet (Zhao et al, 2019), waar het wegval van kiemplanten veroorzaakt).…”

“…The pathogen can cause diseases in plant families including Solanaceae, Poaceae, Amaranthaceae, Fabaceae, Brassicaceae, Rubiaceae, Araceae, Malvaceae, Moraceae, and Linaceae (Mayo et al, 2015;Verwaaijen et al, 2017;Ajayi-Oyetunde and Bradley, 2018). It is divided into 14 AGs based on its special genetic and biological characteristics, including AG-1 to AG-13 and a bridging isolate AG-BI (Parissa and Tarighi, 2011), among which AG-1 to AG-13 were reported to cause Rhizoctonia disease on potato (Balali et al, 1995;Truter and Wehner, 2004;Yanar et al, 2005;Woodhall et al, 2008;Yang et al, 2015;Gush et al, 2019;Murdock et al, 2019;Yang et al, 2019;Lopez Corrales et al, 2023). It is widely known that R. solani AG-3 PT is notably aggressive, primarily causing stem canker or black scurf on potatoes (Balali et al, 1995;Woodhall et al, 2008Woodhall et al, , 2013Fiers et al, 2011;Yang et al, 2015).…”

Black scurf caused by Rhizoctonia solani severely affects potato production. Through amplification of V3-V4 and ITS1-5f variable regions of 16S and internal transcribed spacer (ITS) rRNA, the study was based on the location (Kunming, Qujing, and Zhaotong), plant components (rhizosphere soil and roots), and sample types (healthy and diseased) to assess the diversity of bacterial and fungal communities. We found plant components significantly influence microbial diversity, with rhizosphere soil being more diverse than roots, and the microbial community in the root is mainly derived from the rhizosphere soil. Moreover, the rhizosphere soil and roots of healthy potato plants exhibit greater microbial diversity compared to those of potato plants infected by Rhizoctonia solani. Bacterial phyla Actinobacteriota and Acidobacteriota were enriched in rhizosphere soil compared to that of roots, whereas Proteobacteria and Cyanobacteria showed the opposite trend. Fungal phylum Ascomycota was found in low relative abundance in rhizosphere soil than in roots, whereas Basidiomycota showed the opposite trend. Bacterial genera including Streptomyces, Lysobacter, Bacillus, Pseudomonas, Ensifer, Enterobacter, and the Rhizobium group (Allorhizobium, Neorhizobium, Pararhizobium, Rhizobium), along with fungal genera such as Aspergillus, Penicillium, Purpureocillium, and Gibberella moniliformis, have the potential ability of plant growth promotion and disease resistance. However, most fungal species and some bacterial species are pathogenic to potato and could provide a conducive environment for black scurf infection. Interaction within the bacterial network increased in healthy plants, contrasting with the trend in the fungal network. Our findings indicate that R. solani significantly alters potato plant microbial diversity, underscoring the complexity and potential interactions between bacterial and fungal communities for promoting potato plant health and resistance against black scurf.
