“…Vectors play vital roles in viral long-distance transmission and prevalence [30]. This study identified aphid-borne viruses CMV [31], ChiVMV [32], TVDV [33], and PLRV [34], as well as thrips-borne TSWV [35], infecting A. carmichaelii plants. Potyviruses [36], certain cheraviruses [19], and the majority of carlaviruses [37] are transmitted by aphids.…”

Aconitum carmichaelii is a herbaceous herb indigenous to China that has been cultivated for traditional medicine for centuries. Virus-like symptoms of A. carmichaelii plants were observed on leaves in some A. carmichaelii plantations in Zhanyi and Wuding Counties, Yunnan Province, southwest China. High-throughput sequencing (HTS) was performed on 28 symptomatic plants, and the results revealed infection with 11 viruses, including 2 novel viruses and 9 previously described viruses: Aconitum amalgavirus 1 (AcoAV-1), aconite virus A (AcVA), cucumber mosaic virus (CMV), currant latent virus (CuLV), apple stem grooving virus (ASGV), chilli veinal mottle virus (ChiVMV), tomato spotted wilt orthotospovirus (TSWV), tobacco vein distorting virus (TVDV), and potato leafroll virus (PLRV). Two novel viruses tentatively named Aconitum potyvirus 1 and Aconitum betapartitivirus 1, were supported by sequence and phylogenetic analysis results of their genomes. We proposed the names Potyvirus aconiti and Betapartitivirus aconiti. RT-PCR assays of 142 plants revealed the predominance and widespread distribution of CMV, AcVA, and AcoPV-1 in plantations. The detection of isolates of CuLV, ASGV, ChiVMV, TSWV, TVDV, and PLRV infections for the first time in A. carmichaelii expands their known host ranges.

“…Regarding the viruses detected in A. carmichaeli, it is well-documented that CMV [38], ASGV [39,40], ChiVMV [41], PLRV [34], TVDV [33,42], and TSWV [38] have the ability to infect other economically important crops. The findings reported in this study suggest that the host range of these viruses is expanding.…”

Aphids are serious insect pests for agricultural and horticultural crops and may cause the major economic losses. Insecticides used to control aphids have caused environmental pollution and the insecticide residues in agricultural products. A new protease inhibitor gene from bacterium Xenorhabdus bovienii (Xbpi‐1) and the protease inhibitor protein expressed by the gene against the pea aphid (Acyrthosiphon pisum Harris; Hemiptera: Aphididae) have been reported, however, effects of the PIP on the symbiotic bacteria, Buchnera aphidicola, and gene expression in pea aphids are unknown. By assessing the quantity of B. aphidicola, the primary symbiotic bacterium, in the aphid fed on an artificial diet containing 100 and 500 μg/mL Xbpi‐1, we observed a substantial reduction in its population by 27% and 46%, respectively, as analysed by real‐time quantitative reverse transcription PCR (qRT‐PCR). Furthermore, the growth of other aphid‐associated bacteria was also significantly inhibited by Xbpi‐1. To elucidate the mechanisms at the gene level, we conducted transcriptome analysis and identified differentially expressed genes (DEGs). Subsequent Gene Ontology (GO) analysis of the 213 DEGs shed light on the impact of Xbpi‐1 on aphid metabolism processes and gene expression. Notably, the results highlighted several aphid nutrient metabolism pathways affected by Xbpi‐1, which are relevant to vector‐borne diseases. These pathways encompass crucial factors such as heat shock proteins, cuticle proteins and proteases. The results from this study revealed that the PIP had a novel mechanism against pea aphids by having adverse effects on the primary symbiotic bacteria in pea aphids and affecting aphid gene expression, showing that the PIP may be a promise bioinsecticide for aphid control in the future.
