Transcriptome Mining Expands Knowledge of RNA Viruses across the Plant Kingdom

Jonathon C. O. Mifsud et al.

Summary: Our current understanding of plant viruses is mainly based on economically important host species. However, we have limited knowledge about viruses infecting basal plant lineages such as ferns, lycophytes, bryophytes, and charophytes. To expand our understanding, we conducted a broad-scale viral survey of species across the plant kingdom. We found that basal plants harbor a wide diversity of RNA viruses, including some that may belong to a new virus family. This study provides insights into the evolutionary history of core plant virus genes and genome segments and emphasizes the scarcity of research in these species.

A new flavi-like virus identified in populations of wild carrots

Deborah Schonegger et al.

Summary: We have discovered a new virus related to the Flaviviridae family in wild carrots using a high-throughput sequencing method. This virus, named carrot flavi-like virus 1 (CtFLV-1), has a large genome and shares similarities with flavi-like viruses from arthropods as well as a plant-associated virus, gentian Kobu-sho-associated virus (GKSaV). The similarities in their sequences suggest that GKSaV and CtFLV-1 could belong to a new genus of plant-associated viruses.

A Novel Flavi-like Virus in Alfalfa (Medicago sativa L.) Crops along the Snake River Valley

Jennifer Dahan et al.

Summary: Alfalfa fields in Idaho were found to harbor various viruses, with a new flavi-like virus called Snake River alfalfa virus (SRAV) identified for the first time in a plant host. The study suggests a possible role of Frankliniella occidentalis in the transmission of these viruses, including SRAV, in alfalfa crops.

Bioinformatic Analysis Predicts a Novel Genetic Module Related to Triple Gene and Binary Movement Blocks of Plant Viruses: Tetra-Cistron Movement Block

Sergey Y. Morozov et al.

Summary: This study discovered a novel putative-related movement gene module, called tetra-cistron movement block (TCMB), in the virus-like transcriptomes of moss and Antarctic flowering plant. These TCMBs are encoded by smaller RNA components of putative two-component viruses related to plant benyviruses. The involvement of replicative beny-like helicases in the evolution of the BMB and TCMB movement genetic modules was suggested based on phylogenetic analysis.

Distinct Mechanisms of Endomembrane Reorganization Determine Dissimilar Transport Pathways in Plant RNA Viruses

Andrey G. Solovyev et al.

Summary: Plant viruses utilize the endomembrane system of infected cells for replication and cell-to-cell transport. The replication of viral RNA genomes occurs in the cytoplasm and requires virus-encoded proteins to induce reorganization of the endomembrane compartments. The transport of virus genomes between cells is facilitated by virus-encoded movement proteins. Different plant viruses utilize different sets of movement proteins and employ distinct mechanisms of endomembrane reorganization for cell-to-cell transport.

Reticulon-like properties of a plant virus-encoded movement protein

Ekaterina A. Lazareva et al.

Summary: The movement protein BMB2 from Hibiscus green spot virus induces constriction of ER tubules, increasing the permeability of PD and facilitating intercellular virus spread. These reticulon-like proteins are also found in other RNA viruses, suggesting a common mechanism for viral spread.

Detection and molecular characterization of Wheat stripe mosaic virus on wheat in South Africa

T. G. Terefe et al.

Summary: A previously unknown disease affecting wheat in South Africa has been identified as being caused by Polymyxa graminis and Wheat Stripe Mosaic Virus (WhSMV). WhSMV, recently described in Brazil and Paraguay, was detected in all symptomatic leaf samples tested. The disease's epidemiology and control methods are currently unknown due to its recent discovery.

Summary: Researchers evaluated the chronological possibility of proposed plastid origins and transmissions in eukaryotic phytoplankton through Bayesian molecular clock analyses. The study established a timeframe for the origin of red algal-derived plastids under scenarios of serial endosymbiosis, revealing that the hypotheses of serial endosymbiosis are chronologically possible.

Arginine methylation of SARS-Cov-2 nucleocapsid protein regulates RNA binding, its ability to suppress stress granule formation, and viral replication

Ting Cai et al.

Summary: In this study, PRMT1 was found to methylate the SARS-CoV-2 nucleocapsid (N) protein, which plays a crucial role in viral replication. Inhibition of arginine methylation by type I PRMT inhibitors reduced viral replication by affecting the interaction between the N protein and the viral genomic RNA, highlighting a potential therapeutic strategy for targeting viral genome packaging and assembly.

Experimental taphonomy of organelles and the fossil record of early eukaryote evolution

Emily M. Carlisle et al.

Summary: Experimental research on the decay of organelles in red and green algae suggests that chloroplasts are more resistant to decay than nuclei, while pyrenoids are unlikely to be preserved. This indicates potential differential organelle preservation in seed plants and prompts a reevaluation of the early eukaryotic fossil record.
