“…In this study, FoPV1 was shown to have a reduced pathogenicity phenotype according to the comparison of the virulence of the present strain of FoPV1 (FCR51) and the cured strain of the virus (FCR51VF). Moreover, compared with the cured strain (FCR51VF), FCR51 has a lower conidia production, which is a positive correlation with the virulence of F. oxysporum [ 48 ]. Thus, FoPV1 has obvious hypovirulence to F. oxysporum by directly or indirectly reducing sporulation function.…”

Root rot as a result of Salvia miltiorrhiza is a common root disease caused by Fusarium spp., which has become one of the main diseases affecting the production of S. miltiorrhiza. Currently, several hypovirulence-related mycoviruses have been identified in many phytopathogenic fungi, including Fusarium spp., which show potential as biological controls. In this study, we report a new mycovirus, Fusarium oxysporum partitivirus 1 (FoPV1), isolated from F. oxysporum strain FCR51, which is a causal agent of S. miltiorrhiza dry rot. The FoPV1 genome contains two double-stranded RNA segments (dsRNA1 and dsRNA2). The size of dsRNA1 is 1773 bp, and it encodes a putative RNA-dependent RNA polymerase (RdRp). The dsRNA2 is 1570 bp in length, encoding a putative capsid protein (CP). Multiple sequence alignments and phylogenetic analyses based on the amino acid sequences of the RdRp and the CP proteins indicated that FoPV1 appears to be a new member of the family Partitiviridae that is related to members of the genus Gammapartitivirus. Pathogenicity assay showed that FoPV1 confers hypervirulence to its host, F. oxysporum. This is the first report of a partitivirus infecting F. oxysporum and the first hypovirulence-related mycovirus from the causal agent of S. miltiorrhiza dry rot.

Plant diseases are a major threat affecting the sustainability of global agriculture. Although the breeding of new resistant cultivars is considered to be the primary approach to prevent and control plant diseases, it is dependent on an in‐depth understanding of plant–pathogen interactions. At present, we have an in‐depth understanding of the interactions between model plants and pathogens, such as Arabidopsis thaliana and rice, but we are still in the beginning stage for more non‐model plants (e.g., medicinal plants). Panax notoginseng is the primary source of the high‐value active ingredient triterpenoid saponins. Root rot disease in P. notoginseng has attracted research attention because of its high destructiveness. Understanding the infection stages and strategies of pathogens, plant resistance mechanisms and induced plant defence against pathogens is essential to support agricultural sustainable development of P. notoginseng. Here, we review and summarize, with root rot of P. notoginseng as a model, the current knowledge of plant–pathogen interaction, and feasability of use of microorganisms and secondary metabolites as sources of biological control agents at a low cost. Finally, we also discuss the importance of plant–pathogen interactions in resistance breeding, thereby providing a new strategy to develop green agriculture for non‐model plants.

“…ROS accumulation negatively regulates the pathogenicity of Fusarium oxysporum f. sp. momordicae [95]. Research data show that QSOX1 in plants is a REDOX sensor that restricts the production of ROS by connecting ROS and active nitrogen signals, and negatively regulates plant immunity [96].…”

Duplication events occur very frequently during plant evolution. The genes in the duplicated pathway or network can evolve new functions through neofunctionalization and subfunctionalization. Flavonoids are secondary metabolites involved in plant development and defense. Our previous transcriptomic analysis of F6 recombinant inbred lines (RILs) and the parent lines after Fusarium oxysporum f. sp. vasinfectum (Fov) infection showed that CHI genes have important functions in cotton. However, there are few reports on the possible neofunctionalization differences of CHI family paralogous genes involved in Fusarium wilt resistance in cotton. In this study, the resistance to Fusarium wilt, expression of metabolic pathway-related genes, metabolite content, endogenous hormone content, reactive oxygen species (ROS) content and subcellular localization of four paralogous CHI family genes in cotton were investigated. The results show that the four paralogous CHI family genes may play a synergistic role in Fusarium wilt resistance. These results revealed a genetic channelization mechanism that can regulate the metabolic flux homeostasis of flavonoids under the mediation of endogenous salicylic acid (SA) and methyl jasmonate (MeJA) via the four paralogous CHI genes, thereby achieving disease resistance. Our study provides a theoretical basis for studying the evolutionary patterns of homologous plant genes and using homologous genes for molecular breeding.
