In this study, a constructed infectious clone of TYLCV was used for the exploration of tomato and tobacco plants' response to virus infection. Infected plants exhibit typical symptoms of TYLCV, including leaf chlorosis, curled, and plant dwarfing. Reactive oxygen species (ROS) accumulated, and severe cell necrosis appeared in the tomatoes and tobacco that were infected. After TYLCV infection, 6,775 and 900 genes' expressions were up-regulated in tomatoes and tobacco, including MYB and MADS-box transcription factors, serine/threonine protein kinase, heat shock proteins, cytochrome P450s, E3 ubiquitin-protein ligase, RAV transcription factors. Several stress-responsive kinases involved in autophagy were significantly up-regulated in tobacco but not in tomato. Moreover, silencing the RAV transcription factor, which is associated with the salicylic acid (SA) induced antiviral signaling, led to decreased virus abundance in tomato leaves. The results are helpful for an in-depth understanding of plants' resistance to TYLCV infection.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143772862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To survey the incidence of cyst nematodes in Kimchi-cabbage fields, 469 soil samples were collected from the main producing areas between 2018 and 2021. Only cyst nematodes belonging to the genus Heterodera were investigated, and the overall nematode incidence was found to be 40%. Regionally, the highest incidence was observed in Taebaek, reaching 89%, with mean densities of cysts and eggs per 500 cm³ of soil recorded at 522 and 49,734, respectively. Based on Bayesian analysis of the mitochondrial DNA cytochrome c oxidase subunit I gene sequence, the cyst nematodes were identified as four species: clover cyst nematode (Heterodera trifolii, HT, frequency: 78%), soybean cyst nematode (H. glycines, HG, 11%), sugar beet cyst nematode (H. schachtii, 4%), and white soybean cyst nematode (H. sojae, HSo, 2%). Mixed infestations were found in some fields, with HT + HG (4%) and HG + HSo (1%). These results indicate that HT is the dominant species in the main Kimchi-cabbage producing areas in Korea. In conclusion, implementing effective HT management strategies is critical to minimize economic losses in Kimchi-cabbage production in Korea.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":"41 2","pages":"201-209"},"PeriodicalIF":1.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11986354/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144000575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when properly implemented, alternate wetting and drying can mitigate these issues. Despite its potential advantages, the effects of different water management practices on the soil microbiome are not well understood. This study explored how intermittent flooding and drying influence the soil microbiome by analyzing microbial communities under varying moisture conditions using Illumina sequencing. The results showed notable shifts in the abundance of Bacillota and Actinomycetota in response to fluctuations in water levels, although the overall microbial abundance returned to its original state under stable moisture conditions. In contrast, the abundance of Chloroflexota, which increased during waterlogging, remained elevated even under dry conditions. Additionally, microbial interactions were more pronounced during waterlogging compared to both moist and dry conditions. Overall, this research underscores the significant role of water management in shaping soil bacterial communities.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":"41 2","pages":"231-239"},"PeriodicalIF":1.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11986366/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144018890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cysts are commonly used for cyst nematode bioassays because many eggs are included inside cyst. Traditionally, cysts are extracted from the soil using the paper strip method or the centrifugal flotation method (CFM) combined with sieving. The specific gravity of sugar solution (SGSS) is often used in the CFM; however, the efficiency of cyst extraction and egg hatching in the CFM has not been studied. In this study, we assessed the effects of SGSS in a specific gravity range of 1.15 to 1.30 in the CFM on the cyst extraction and egg hatching of clover cyst nematode (Heterodera trifolii) and sugar beet cyst nematode (H. schachtii). High SGSS in the CFM within the range of 1.15 to 1.30 was positively correlated with the extraction of more cysts. Egg-hatching rates were not different between SGSSs, indicating that SGSS did not directly affect egg-hatching rates. These results showed that the cysts of cyst nematodes can be efficiently extracted with high SGSS in the CFM.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":"41 2","pages":"225-230"},"PeriodicalIF":1.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11986351/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144040617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cultivation also generates tons of supernatant waste that require detoxification and disposal. Recent research has focused on recycling waste supernatant as a plant protectant and biofertilizer, although, to date, most studies have considered its use as a biological control of pathogens infecting dicot plants. By contrast, the current study evaluated whether Chlorella supernatant could protect turfgrass (Agrostis stolonifera), a monocot plant widely used as a turfgrass, against dollar spot disease caused by the fungal pathogen Clarireedia jacksonii (formerly Sclerotinia homoeocarpa) under greenhouse and field conditions. Foliar application of supernatants from Chlorella sp. ABC001 and HS2 cultures reduced the incidence of dollar spot disease in turfgrass under both greenhouse and field conditions without directly inhibiting growth. The effects of supernatant application on the rhizosphere microbiome were investigated using 16S rRNA amplicon sequencing. Application of ABC001 and HS2 supernatants modulated the structure of the rhizosphere microbiome and enriched specific microbial taxa that improved turfgrass health in the presence of C. jacksonii. The application of waste Chlorella supernatant therefore offers an alternative method for protecting monocot plants against fungal pathogens, while also enhancing the composition of soil microbes in the rhizosphere.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":"41 2","pages":"210-224"},"PeriodicalIF":1.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11986362/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144024017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate the pyraclostrobin sensitivity of Botryosphaeria spp. in Korea, 329 isolates were collected from eight regions between 2005 and 2023. Phylogenetic analysis based on the concatenated sequences of internal transcribed spacer, tef1, and tub2 revealed B. sinensis (287 out of 329 isolates) and B. kuwatsukai (42 out of 329 isolates). EC50 values of isolates ranged from 0.01 to 34.16 μg/ml (average, 3.03 μg/ml). Mean EC50 values and frequency distributions were similar among isolate groups, indicating no significant differences in sensitivity. Twenty less-sensitive and 20 sensitive isolates were selected and their cytochrome b (cyt b) genes analyzed, revealing no mutations in codons 129, 137, and 143. Whole gene sequencing revealed three distinct cyt b gene structures among Botryosphaeria spp., and all strains, including those with different EC50 values and species, showed consistent amino acid sequences. Furthermore, control efficacy on pyraclostrobin-treated apple fruits indicated no significant differences between the five least sensitive and five most sensitive isolates. These results provide the baseline sensitivity of Botryosphaeria spp. to pyraclostrobin and highlight the structural characteristics of their cyt b gene. In conclusion, the assessment of Botryosphaeria isolates from various regions in Korea revealed no evidence of resistance to pyraclostrobin so far. However, the risk of resistance of Botryosphaeria populations still exists so it is assumed that continuous monitoring of risk assessment is necessary for Botryosphaeria in Korea.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":"41 2","pages":"189-200"},"PeriodicalIF":1.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11986353/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143975025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
