Abstract
The negative effects of potyvirus diseases on the agricultural industry are extensive and global. Understanding how protein-protein interactions contribute to potyviral infections is imperative to developing resistant varieties that help counter the threat potyviruses pose. While many protein-protein interactions have been reported, only a fraction are essential for potyviral infection. Accumulating evidence demonstrates that potyviral infection processes are interconnected. For instance, the interaction between the eukaryotic initiation factor 4E (eIF4E) and viral protein genome-linked (VPg) is crucial for both viral translation and protecting viral RNA (vRNA). Additionally, recent evidence for open reading frames on the reverse-sense vRNA and for nonequimolar expression of viral proteins has challenged the previous polyprotein expression model. These discoveries will surely reveal more about the potyviral protein interactome. In this review, we present a synthesis of the potyviral infection cycle and discuss influential past discoveries and recent work on protein-protein interactions in various infection processes.

Abstract
Rubisco small subunit (RbcS), a core component with crucial effects on the structure and kinetic properties of the Rubisco enzyme, plays an important role in response to plant growth, development, and various stresses. Although Rbcs genes have been characterized in many plants, their muti-functions in soybeans remain elusive. In this study, a total of 11 GmRbcS genes were identified and subsequently divided into three subgroups based on a phylogenetic relationship. The evolutionary analysis revealed that whole-genome duplication has a profound effect on GmRbcSs. The cis-acting elements responsive to plant hormones, development, and stress-related were widely found in the promoter region. Expression patterns based on the RT-qPCR assay exhibited that GmRbcS genes are expressed in multiple tissues, and notably Glyma.19G046600 (GmRbcS8) exhibited the highest expression level compared to other members, especially in leaves. Moreover, differential expressions of GmRbcS genes were found to be significantly regulated by exogenous plant hormones, demonstrating their potential functions in diverse biology processes. Finally, the function of GmRbcS8 in enhancing soybean resistance to soybean mosaic virus (SMV) was further determined through the virus-induced gene silencing (VIGS) assay. All these findings establish a strong basis for further elucidating the biological functions of RbcS genes in soybeans.

PLANTS (BASEL, SWITZERLAND) 2024; 13:1236. [PMID: 38732454 PMCID: PMC11085613 DOI: 10.3390/plants13091236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Revised: 04/25/2024] [Accepted: 04/26/2024] [Indexed: 05/13/2024]
Abstract
The best-characterized functional motifs of the potyviral Helper-Component protease (HC-Pro) responding for aphid transmission, RNA silencing suppression, movement, symptom development, and replication are gathered in this review. The potential cellular protein targets of plant virus proteases remain largely unknown despite their multifunctionality. The HC-Pro catalytic domain, as a cysteine protease, autoproteolytically cleaves the potyviral polyproteins in the sequence motif YXVG/G and is not expected to act on host targets; however, 146 plant proteins in the Viridiplantae clade containing this motif were searched in the UniProtKB database and are discussed. On the other hand, more than 20 interactions within the entire HC-Pro structure are known. Most of these interactions with host targets (such as the 20S proteasome, methyltransferase, transcription factor eIF4E, and microtubule-associated protein HIP2) modulate the cellular environments for the benefit of virus accumulation or contribute to symptom severity (interactions with MinD, Rubisco, ferredoxin) or participate in the suppression of RNA silencing (host protein VARICOSE, calmodulin-like protein). On the contrary, the interaction of HC-Pro with triacylglycerol lipase, calreticulin, and violaxanthin deepoxidase seems to be beneficial for the host plant. The strength of these interactions between HC-Pro and the corresponding host protein vary with the plant species. Therefore, these interactions may explain the species-specific sensitivity to potyviruses.

Rubisco small subunit (RbCS) is co-opted by potyvirids as the scaffold protein in assembling a complex for viral intercellular movement. PLoS Pathog 2024; 20:e1012064. [PMID: 38437247 PMCID: PMC10939294 DOI: 10.1371/journal.ppat.1012064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 03/14/2024] [Accepted: 02/21/2024] [Indexed: 03/06/2024] Open
Abstract
Plant viruses must move through plasmodesmata (PD) to complete their life cycles. For viruses in the Potyviridae family (potyvirids), three viral factors (P3N-PIPO, CI, and CP) and few host proteins are known to participate in this event. Nevertheless, not all the proteins engaging in the cell-to-cell movement of potyvirids have been discovered. Here, we found that HCPro2 encoded by areca palm necrotic ring spot virus (ANRSV) assists viral intercellular movement, which could be functionally complemented by its counterpart HCPro from a potyvirus. Affinity purification and mass spectrometry identified several viral factors (including CI and CP) and host proteins that are physically associated with HCPro2. We demonstrated that HCPro2 interacts with both CI and CP in planta in forming PD-localized complexes during viral infection. Further, we screened HCPro2-associating host proteins, and identified a common host protein in Nicotiana benthamiana-Rubisco small subunit (NbRbCS) that mediates the interactions of HCPro2 with CI or CP, and CI with CP. Knockdown of NbRbCS impairs these interactions, and significantly attenuates the intercellular and systemic movement of ANRSV and three other potyvirids (turnip mosaic virus, pepper veinal mottle virus, and telosma mosaic virus). This study indicates that a nucleus-encoded chloroplast-targeted protein is hijacked by potyvirids as the scaffold protein to assemble a complex to facilitate viral movement across cells.

Transcriptomic and genomic analysis provides new insights in molecular and genetic processes involved in zucchini ZYMV tolerance. BMC Genomics 2022; 23:371.

Abstract
BACKGROUND Cucurbita pepo is highly susceptible to Zucchini yellow mosaic virus (ZYMV) and the resistance found in several wild species cannot be considered as complete or broad-spectrum resistance. In this study, a source of tolerance introgressed in C. pepo (381e) from C. moschata, in True French (TF) background, was investigated 12 days post-inoculation (DPI) at transcriptomic and genomic levels. RESULTS The comparative RNA-sequencing (RNA-Seq) of TF (susceptible to ZYMV) and 381e (tolerant to ZYMV) allowed the evaluation of about 33,000 expressed transcripts and the identification of 146 differentially expressed genes (DEGs) in 381e, mainly involved in photosynthesis, transcription, cytoskeleton organization and callose synthesis. By contrast, the susceptible cultivar TF triggered oxidative processes related to response to biotic stimulus and activated key regulators of plant virus intercellular movement. In addition, the discovery of variants located in transcripts allowed the identification of two chromosome regions rich in Single Nucleotide Polymorphisms (SNPs), putatively introgressed from C. moschata, containing genes exclusively expressed in 381e. CONCLUSION 381e transcriptome analysis confirmed a global improvement of plant fitness by reducing the virus titer and movement. Furthermore, genes implicated in ZYMV tolerance in C. moschata introgressed regions were detected. Our work provides new insight into the plant virus recovery process and a better understanding of the molecular basis of 381e tolerance.

Abstract
To develop a new antiviral preparation from a microbial source, the halophilic bacterium Bacillus pumilus E303035 was isolated from a soil sample collected at Qarhan Salt Lake in Qinghai, China. The inhibitory activity of an ethyl acetate extract of its fermentation broth was higher than that of an n-butanol extract. After isolation and purification, 9 compounds were obtained: cyclo(L-Leu-L-Pro) (1), cyclo(L-Pro-L-Tyr) (2), Brevianamide F (3), 2-(3-Indolyl) ethanol (4), N-[2-(1H-indol-3-yl) ethyl] acetamide (5), 3, 3-di(1H-indol-3-yl)propane-1,2-diol (6), Lincomycin B (7), dibutylphthalate (8), and p-hydroxyphenethyl alcohol (9). Compounds 1, 5, and 9 showed inhibitory activities against potato virus Y (PVY). Compounds 1, 4, and 9 had significant inhibitory activity against genes HC-pro, P3, and Nib, compound 5 against gene P3, and compounds 1 and 4 against NIa. Compounds 1, 4, 5, and 9 had significant inhibitory activity against genes VPg and 6K1. Active compounds 1, 5, and 9 had various effects on the expression of viral genes related to pathogenesis. Expression of genes cullin and XTH was up-regulated and CP was down-regulated, compared to the positive control. In conclusion, compounds 1, 5, and 9 might be considered as potential antiviral agents for future development.
