Begomoviruses are whitefly-transmitted, single-stranded DNA viruses that cause serious infections in crop plants and are often also associated with non-cultivated plants. Here, we report the detection of two new begomoviruses in Pavonia sp. (Malvaceae). Sequence comparisons and phylogenetic analysis showed that these novel viruses are related to New World begomoviruses. The nucleotide sequences of the DNA-A of both viruses had the highest similarity to abutilon mosaic Bolivia virus (AbMBoV). Based on symptoms observed in the field and considering the host, we propose the names pavonia mosaic virus (PavMV) and pavonia yellow mosaic virus (PavYMV) for these two new begomoviruses.

RNA viruses have evolved numerous strategies to overcome host resistance and immunity, including the use of multifunctional proteases that not only cleave viral polyproteins during virus replication but also deubiquitinate cellular proteins to suppress ubiquitin (Ub)-mediated antiviral mechanisms. Here, we report an approach to attenuate the infection of Arabidopsis thaliana by Turnip Yellow Mosaic Virus (TYMV) by suppressing the polyprotein cleavage and deubiquitination activities of the TYMV protease (PRO). Performing selections using a library of phage-displayed Ub variants (UbVs) for binding to recombinant PRO yielded several UbVs that bound the viral protease with nanomolar affinities and blocked its function.

The global human immunodeficiency virus 1 (HIV-1) pandemic is driven by the extraordinary genetic diversity of the virus, largely resulting from frequent recombination events. These events generate circulating recombinant forms (CRFs) and unique recombinant forms, which significantly contribute to the complexity of HIV-1 epidemiology, especially within key populations, such as men who have sex with men (MSM). Here, we identified three novel HIV-1 recombinant strains consisting of the CRF01_AE and CRF07_BC subtypes from HIV-positive MSM in Baoding City, Hebei Province, China.

Wheat viruses are major yield-reducing factors, with mixed infections causing substantial economic losses. Determining field virus populations is crucial for effective management and developing virus-resistant cultivars. This study utilized the high-throughput Oxford Nanopore sequencing technique (ONT) to characterize wheat viral populations in major wheat-growing counties of Kansas from 2019 to 2021.

Maize lethal necrosis (MLN) is a significant threat to food security in Sub-Saharan Africa (SSA), with limited commercial inbred lines displaying tolerance. This study analyzed the transcriptomes of four commercially used maize inbred lines and a non-adapted inbred line, all with varying response levels to MLN. RNA-Seq revealed differentially expressed genes in response to infection by maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV), the causative agents of MLN.
