This study presents the first sequenced genome of WMV from Iraq and the second from Iran. The near-complete genome sequences of Iranian (In) and Iraqi (Iq) isolates were, respectively, 9999 and 10,041 nucleotides in length, excluding the 3′-terminal poly(A) tail. WMV-Iq and WMV-In shared nucleotide identities of 92.61–96.32% with those of 30 worldwide representative WMV isolates in GenBank and identities of 93.04–93.90% with a previously reported Iranian isolate IR02-54. Phylogenetic analysis based on the genomic sequences clustered all 32 isolates into seven groups (G1–G7), in which WMV-Iq and WMV-In clustered alongside 12 isolates from Asia, Europe, and America in group G1. Phylogenetic analysis of nucleotide sequences of the coat protein gene of WMV isolates resolved into five phylogroups (I–V) and both isolates, WMV-Iq and WMV-In, clustered together with isolates in group I and contain the N-terminal KEA motif, which is the characteristic of group I isolates. Our results show that WMV-Iq and WMV-In are recombinant isolates with multiple recombination events detected across the genome. Symptom intensity of WMV isolates in experimental hosts was variable and depended upon the host species, virulence of isolates, and environmental conditions.","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":"52 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141778250","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}

To test this hypothesis, the bacterial community within the vascular tissue of asymptomatic Eucalyptus grandis x E. urophylla trees, and those displaying varying stages of infection in China and Indonesia were compared using 16S rRNA profiling. Asymptomatic trees growing in areas where bacterial infections had never previously been reported to occur were included as controls. Ralstonia species were found within the vascular tissue of both asymptomatic and symptomatic trees, in high abundance. In the control samples, bacterial diversity within the vascular tissue was high with a low abundance of Ralstonia species.

Our study aimed to identify and evaluate the pathogenicity of these isolates. Based on cultural characteristics, microscopic morphological features and phylogenetic analyses of the internal transcribed spacer (ITS) and partial large subunit (LSU) nrDNA, translation elongation factor 1α (EF-1α), and β-tubulin (BT) gene sequences combination, eight Botryosphariaceae species, including Botryosphaeria dothidea, Diplodia citricarpa, Dothiorella plurivora, Dothiorella sarmentorum, Lasiodiplodia mahajangana, Lasiodiplodia theobromae, Neofusicoccum parvum and Neoscytalidium dimidiatum, were isolated and identified from Tamarix and Haloxylon species. Botryosphaeria dothidea, Neofusicoccum parvum, Lasiodiplodia theobromae and Neoscytalidium dimidiatum were recorded on both Tamarix and Haloxylon species, while the remaining species were detected only from Tamarix or Haloxylon species. Pathogenicity tests were conducted on detached shoots of Tamarix aphylla and Haloxylon ammodendron as well as branches of both tree species under field conditions. Lasiodiplodia mahajangana was the most virulent species and caused the longest wood lesion lengths on both tree species. Most of these species are reported for the first time from their respective hosts. Our findings in this study may be able to improve the basic information on the importance of Botryosphaeriaceae family on desert trees in Iran as well as other countries.","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":"150 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141576878","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}

Initially, a diverse panel of 95 genotypes were evaluated against foxtail millet leaf blast under field conditions at four different hotspot locations viz., Bangalore, Mandya. Nandyal and Vizianagaram during Kharif 2021. Based on the field reaction, 22 genotypes were selected for further screening under glasshouse conditions along with ISe175 (resistant check) and SiA326 (susceptible check). Four (4) leaf blast isolates namely FoxPs-3, 5, 6 and 15 from different locations were used to identify putative host differentials based on differential reaction. A set of 12 putative host differentials viz., ISe1256, GS55, GS2261, ISe1408, GS73, ISe1299, GS101, ISe746, ISe1655 and ISe1745 along with a resistant (ISe175) and susceptible check (SiA326), showing differential host responses were proposed as candidate host differentials to assess the pathogenic variability. The pathogenic profiling of 15 isolates on the identified putative host differential set has revealed four major pathogenic groups indicating the existence of pathotypes in Pyricularia population infecting foxtail millet in India. A set of putative host differentials identified and information on pathotypes of P. setariae is highly useful in better understanding of host pathogen interaction, existence of pathotype in a crop ecosystem and also serve as tools for identification of suitable disease resistant genotypes for resistant breeding programme.","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":"28 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141576877","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}

At the same time, predictive models need to account for the possible effect of environmental changes and of abiotic stressors on disease severity for all diseases. By wound-inoculating Botryosphaeria dothidea on potted California coast live oaks and Cryptostroma corticale on potted silver maples, simultaneously in well-watered and in water-deprived conditions, I show that drought conditions increase the severity of disease symptoms. I also show that, by including a water-stressed treatment, I can formally prove pathogenicity and fulfill Koch’s postulates for putative pathogens that could not be confirmed in the absence of the stressor. Additionally, I show that the inclusion of data obtained in water stress conditions increases the differentiation between symptoms caused by fungal infection vs. symptoms caused by wound trauma, thus reducing the possible effect of outliers, a significant problem affecting many trials for fulfilling Koch’s postulates conducted with a limited number of replicates. The availability of comparable datasets in the presence and the absence of an abiotic stressor allows for the calculation of an Environmental Disease Component Index. Positive values of the index indicate a significant role of environmental change in disease progression and identify those pathogens that must be modeled factoring in climatic stressors. I suggest that this index may be extremely valuable for identifying pathogens likely to become emergent as climate changes.","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":"24 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141576879","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}

Molecular analysis, specifically comparing nucleotide sequences of the ß-tubulin (ß-tub), cytochrome-B (cyt-B) and Alternaria major allergen gene (Alt a1) using the MycoCosm and NCBI databases, identified these isolates as Alternaria alternata. The phylogenetic tree, constructed via the Maximum-Likelihood method using the Alt a1 gene, demonstrated that all 11 isolates clustered with A. alternata, Sector—Alternaria, alongside reference strains from the NCBI database. Additionally, Alt a1 showed the capability to differentiate sub-groups within Sect.—Alternaria, indicating its intraspecific discriminatory potential.

Fungal species from Uromyces, Phakopsora and Puccinia genera are the main causal agents of the various legume rust diseases. They induce up to 100% yield losses on susceptible cultivars and are emerging as a substantial threat to global food security. Developing durable resistance to rust has thus become a critical breeding objective alongside efforts to improve cultural and disease management practices. This review specifically focuses on the recent advances in understanding and enhancing genetic rust resistance across diverse legume crops. Key topics covered include: (i) the diversity and host range of the rust species affecting legumes; (ii) the disease management strategies from cultural practices to chemical control; (iii) the available screening methods for identifying new sources of resistance; (iv) the genetic basis of resistance, encompassing both major resistance genes and quantitative trait loci; (v) insights into gene regulation and effector molecules leading to legume-rust interactions; and (vi) emerging genomic-assisted breeding techniques that can accelerate the development of durable rust resistance in legumes. Overall, this review highlights the progress made to date and the remaining challenges in sustainably managing rust diseases across diverse legume crops through integrated approaches spanning pathogen biology, advanced phenotyping, genetic resistance, and molecular breeding.","PeriodicalId":16837,"journal":{"name":"Journal of Plant Pathology","volume":"88 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141531177","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}
