Most of these bacteria were originally classified under the Erwinia genus, but are now identified as species of genera Pectobacterium and Dickeya. Studies have shown that genetic and phenotypic diversities of these pathogens vary across regions, and exploring such aspects in different potato-producing areas could provide insights into these bacteria’ ecology. In this study, 84 Taiwanese strains of potato-isolated soft rot bacteria were subjected to phylogenetic and phenotypic assays using the latest classification schemes. Preliminary testing with genus-specific primers suggested that all strains belonged to Pectobacterium. Multilocus sequence analysis divided them into four clades, each represented respectively by the type strain of P. brasiliense, P. carotovorum, P. versatile, and P. aroidearum. Among the species identified, P. brasiliense was found to be the most genetically diverse and prevalent. Phenotypic tests on representative strains of these species showed that all tested strains were able to grow at pH 5.5–10.0 and 16–37 °C. The ability to grow at pH 4.0–41 °C varied across strains, but the differences were unable to discriminate among species. Additional physiological assays were conducted, and while most assays did not allow reliable distinction among species, the indole production test was able to differentiate P. brasiliense strains from the other species. Inoculation of potato tubers revealed great intra-specific heterogeneity among maceration potentials of the tested strains. Interestingly, the maceration potentials of different Pectobacterium species responded differently to elevated temperature. The findings from this work contribute to a broader understanding of Pectobacterium strains affecting potatoes in Taiwan.","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":"16 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different studies have shown that the application of benzothiadiazole (BTH) and arbuscular mycorrhizal fungi (AMF) can effectively control this disease. It has also been reported that both induced and genetically inherited resistance, elevated polyphenol oxidase (PPO) and peroxidase enzyme (POX) activities, and resistance-related genes expression. This study aimed to elucidate the biochemical and genetic responses of sunflower plants under white rot infection and different treatments by measuring the ROS-scavenging enzymes PPO and POX activities in healthy or infected sunflower plants, as well as identifying some defense genes. Sunflower cultivars with different levels of resistance to Sclerotinia sclerotiorum were used. Pregerminated seeds were soaked in an aqueous solution of BTH before being sown into trays and placed in a greenhouse. Before sowing, AMF was also applied to the substrate. Twenty-one-day-old plants were then inoculated with Sclerotinia sclerotiorum. Our results demonstrated that BTH and AMF induced some degree of systemic resistance in sunflower against white rot, especially combined. Even though the amount of pathogen detected in plants only varied between cultivars, not changing when inducers were applied, disease severity was reduced, demonstrating that treatments were effective against white rot. In addition, the activation of defense-related genes correlated well with the degree of resistance observed in plants. Therefore, our results provide insights for a better understanding of the mechanisms underlying induced-resistance to sunflower white rot infections.","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":"32 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(2n = 14), is the third most important legume crop worldwide after common bean and chickpea. Pea production is severely affected by rust caused by Uromyces viciae-fabae. Lignification is one of the most important mechanisms playing a very significant role in plant disease resistance. In the present study, a total of 115 pea entries of the Australian germplasm together with four standard controls were observed for the presence of total lignin content (72 h) and its accumulation in relation to the different components of resistance. Out of all the test entries, one resistant entry ‘EC865975’ showed the maximum increase in total lignin content even more than the resistant check. It also exhibited a low AUDPC (the Area under the Disease Progress Curve) value of 292 and showed formation of smaller pustules measuring 0.7 mm in size with reduction in their number. Further, it was found that the total lignin content was highly negatively correlated (r = -0.796) with AUDPC. The higher accumulation of lignin content was found in resistant test entries over susceptible ones. The principal component analysis of the different parameters revealed that the total lignin content and AUDPC were only the parameters mostly contributing to the total phenotypic variation to the extent of 81.92% as they exhibited their Eigenvalue > 1. Further, the regression analysis considering the total lignin content as the independent variable and AUDPC, size and number of pustules, 100 seed weight and seed area as predictor variables revealed that the total lignin content caused 75.2% alteration in other predictor variables. Hence, the present study confirmed that the lignification can be used as a key biochemical parameter for screening of resistant sources from the various pea germplasms.","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":"48 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fusarium sacchari and F. proliferatum were consistently isolated from symptomatic fruit. In pathogenicity tests on ‘Lady finger’ banana fruit, F. proliferatum was more virulent than F. sacchari. Quantitative Time-of-Flight Mass Spectrometric analysis of secondary metabolites produced by isolates of these two Fusarium species on three different matrices (banana peel, barley and maize kernels) identified 11 mycotoxins. Seven of them (Fusaproliferin, Fumonisins A1, Fumonisins A2 and Fumonisins B1, Hydrolysed Fumonisin B1, Fusarin C and Moniliformin) were detected in matrices contaminated by F. proliferatum isolates. Fumonisin A1 was the prevalent mycotoxin in both maize kernels and banana peel, while Fumonisin A2 prevailed in barley kernels. Similarly, seven mycotoxins (the cyclic hexadepsipeptides Enniatins B2, B3 and B4, Fumonisins A1 and B2, Hydrolysed Fumonisin B1 and Fusarin C) were detected in matrices contaminated by F. sacchari isolates, but they were only in part the same as those produced by F. proliferatum isolates. Fusarin C prevailed in all three matrices colonized by F. sacchari. Fumonisin A1 was detected exclusively in maize kernels while Enniatins B3 and B4, Fumonisin B2 and Hydrolysed Fumonisin B1 were detected exclusively in barley kernels. Overall, F. proliferatum produced a higher amount of mycotoxins than F. sacchari. Moreover, in banana peel both species produced a lower number and amount of mycotoxins than in the other two matrices.","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":"14 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142192673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
