“…The genomes of isolates KPF-1 and KPF-2 are both composed of 9832 nucleotides, excluding the poly(A) tail, and the genome is predicted to encode a polyprotein of 3164 amino acids. However, the complete genome size of Korean TuMV isolates that we obtained previously was 9833 nt [ 16 , 17 ]. By contrast, the complete genome sequences of the new isolates reported here lack a base in the 3’ untranslated region at nt 9753.…”

“…The Chinese cabbage isolates (KBC-1 and KBC-8) were predicted to belong to the World-B group. However, most of the isolates collected from Korea belong to the Basal-BR group [ 16 , 17 ]. The second phylogenetic tree only included Korean TuMV isolates with PVY as an outgroup (Fig.…”

“…The complete genome sequence of each isolate was determined and found to consist of 9832 nucleotides. Interestingly, they lack a nucleotide in the 3’ UTR region when compared to all TuMV strains we have previously collected in South Korea [ 16 , 17 , 27 ].…”

“…The maximum-likelihood method was used to construct a phylogenetic tree with 1000 bootstrap replicates in MEGA software (version 7.0). The complete genome sequences of TuMV strains used in this study were obtained from NCBI (Table 2 ), including isolates previously reported in South Korea [ 16 , 17 , 29 ], two infectious clones constructed in this study (KPF-1 and KPF-2), and four newly collected isolates, KRS-3, KRS-8, KBC-1, and KBC-8 (submitted to NCBI but not yet published).…”

Perilla is an annual herb with a unique aroma and taste that has been cultivated in Korea for hundreds of years. It has been widely cultivated in many Asian and European countries as a food and medicinal crop. Recently, several viruses have been reported to cause diseases in perilla in Korea, including turnip mosaic virus (TuMV), which is known as a brassica pathogen due to its significant damage to brassica crops. In this study, we determined the complete genome sequences of two new TuMV isolates originating from perilla in Korea. Full-length infectious cDNA clones of these two isolates were constructed, and their infectivity was tested by agroinfiltration of Nicotiana benthamiana and sap inoculation of Chinese cabbage and radish plants. In addition, we analyzed the phylogenetic relationship of six new Korean TuMV isolates to members of the four major groups. We also used RDP4 software to conduct recombination analysis of recent isolates from Korea, which provided new insight into the evolutionary relationships of Korean isolates of TuMV.

Sustainable production of Chinese cabbage (Brassica rapa L.) is essential for the economy and food security in South Korea. However, climate change poses significant threats to its growth and quality. Changes in precipitation patterns such as drought and heavy rain can affect the development of crop, leading to stunted growth or disease. This can lead to significant losses in crop yield. In this study, a hybrid modeling system was developed to predict incidence of viral disease and evaluate impacts of combination of virus infection and environmental variabilities (including climate and location) on marketable cabbage yields. The crop growth model was successfully developed using a limited number (n = 7) of previous studies (RMSE 0.25‐0.33 Mg ha−1, R2 = 0.87‐0.99). The developed hybrid modeling system was composed of a virus incident model and a crop growth model. According to simulated results, all study locations had around 20% incidence rates. However, based on the simulation results, the rates of viral disease incidence varied depending on the climate of each year. Among several climatic factors, precipitation had the greatest effect on virus outbreaks. Jeju Island, which had a relatively high rainfall, had a higher disease incidence rate than other provinces. According to shared socioeconomic pathways (SSPs), in SSP245 (an intermediate development pathway), the yield of 1.58 Mg ha−1 was reduced to 1.26 Mg ha−1 due to a 25% viral disease outbreak. In SSP585 (a high development pathway), with an incidence of 23%, the yield was reduced by 0.2 Mg ha−1. These results will be useful for efficiently cultivating crops under various climatic conditions and seeking management methods to minimize damage from viral disease.This article is protected by copyright.
