In Iran, during 2013–16, 16 Gram‐positive corynebacteria‐like strains were recovered from the epiphytic parts of solanaceous vegetables including eggplant, pepper and tomato. The accidentally as a result monitoring for other bacterial pathogens in fields. phenotypically different Clavibacter michiganensis strains. Although none pathogenic on their host isolation or any plants, 12 out common bean, cowpea, mung bean soybean. Colonization by was observed maize, zucchini, faba honeydew melon,...

Abstract We report in this study for the first time occurrence of bacterial spot pepper Iran and both phenotypic genetic characterization its causal agent, Xanthomonas euvesicatoria . Pepper plants grown 15 30 surveyed private gardens commercial fields were infected by pathogen Marand County, East Azerbaijan Province, north‐western Iran. The obtained strains X. had different amylolytic pectolytic activities compared with those reported species elsewhere. Pathogenicity tests showed that...

A 2‐year comprehensive field survey was conducted across major tomato‐growing areas of Iran. Two hundred and thirty‐four tomato fields six tomato‐producing greenhouses were surveyed for the potential presence bacterial spot disease. Five ninety‐six samples with without symptoms analysed. While Xanthomonas spp. found in association plants both from five counties, disease observed only three them. Only strains isolated induced on tomato, while those symptomless caused cabbage common bean. None...

Members of the genus Clavibacter are economically important bacterial plant pathogens infecting a set diverse agricultural crops (e.g., alfalfa, corn, potato, tomato, and wheat). Tomato-associated sp. strains account for great portion genetic diversity genus, C. michiganensissensu stricto (formerly michiganensis subsp. michiganensis), causing canker disease, is considered one most destructive seed-borne agents crop worldwide. However, current taxonomic descriptions do not reflect existing...

The Gram-negative bacterium Xanthomonas translucens infects a wide range of gramineous plants with notable impact on small grain cereals. However, genomics-informed intra-species population structure and virulence repertories the pathogen have rarely been investigated. In this study, complete genome sequences seven X. strains representing an entire set genetic diversity two pathovars pv. undulosa is provided compared those publicly available genomes pathogen. Organization 25 type III...

The genus Xanthomonas contains a set of diverse bacterial strains, most which are known for their pathogenicity on annual crops and fruit trees causing economically important plant diseases. Recently, five strains were isolated from Agrobacterium-induced crown gall tissues amaranth (Amaranthus sp.) weeping fig (Ficus benjamina) plants in Iran. Phenotypic characteristics (i.e. biochemical tests features) whole genome sequence-based core-genome phylogeny followed by average nucleotide identity...

This study provides a phylogeographic insight into the population diversity of

During 2013–2016, 277 tomato fields were surveyed across Iran to monitor the status of bacterial canker tomato, caused by Clavibacter michiganensis subsp. . Altogether, 450 plant samples collected, both with and without symptoms, from which 35 strains recovered. These positive for PCR test performed using ‐specific primer pair CMR 16F1/ 16R1. Based on phylogeny gyrB gene sequences, 31, three one identified as C. , Microbacterium sp. Agrococcus sp., respectively. The 31 further subsp (23...

Tomato bacterial canker caused by Clavibacter michiganensis subsp. is one of the most important seed-borne tomato diseases around globe. The disease was initially reported in 1993 Iran, and it became a rising threat for multibillion dollar industry country during last decade. In this study, using phylogeographic analyses, we determined genetic diversity geographic distribution C. Iran. Our field surveys showed that pathogen expanding into southern eastern areas country. Furthermore,...

Bacterial wilt of dry beans (family Fabaceae) caused by the actinobacterial agent Curtobacterium flaccumfaciens pv. is one most important diseases threatening edible legume production around globe. Despite economic losses due to bacterial disease, pathogen has not so far been investigated for its genomic features, pathogenicity determinants, and virulence strategies. Here we present first complete genome sequence a highly virulent bacteriocin-producing C. strain P990. The bacterium circular...

In contrast to conventional antibiotics, which microorganisms can readily evade, it is nearly impossible for a microbial strain that sensitive antimicrobial proteins convert resistant strain. Therefore, and peptides are promising alternative candidates the control of bacterial infections under investigation. The MAP30 protein Momordica charantia valuable type I ribosome-inactivating (RIP) with anti-HIV anti-tumor activities. Whereas activity some RIPs has been confirmed, less attention paid...

The population dynamics of Xanthomonas arboricola pv. pruni (Xap) and X. citri subsp. (Xcc) was assessed on over three dozen plant species/genotypes under field greenhouse conditions. Both Xap Xcc multiplied red nightshade, black bindweed, Chenopodium , common bean wheat up to 20 days post‐inoculation (dpi) A high bacterial growth rate observed all (alfalfa, mustard, millet prickly lettuce) but one (liquorice) species tested successfully proliferated both lemon sweet 140 dpi, attaining a...

A multiphasic approach was used to decipher the phenotypic features, genetic diversity, and phylogenetic position of 46 Curtobacterium spp. strains isolated from dry beans other annual crops in Iran Spain. Pathogenicity tests, resistance arsenic compounds, plasmid profiling BOX-PCR were performed on strains. Multilocus sequence analysis (MLSA) also five housekeeping genes (i.e., atpD, gyrB, ppk, recA, rpoB) all strains, as well pathotype species. test showed that six out 42 nonpathogenic...

Bacterial leaf streak caused by different pathovars of Xanthomonas translucens is the most important seedborne bacterial disease small grain cereals. However, variations in virulence-associated genomic areas pathogen remain uninvestigated. In this study, diversity transcription activator-like effectors (TALE) was investigated using Southern blotting BamHI-digested DNAs Iranian strains X. translucens. All 65 were assigned into 13 genotypes, where 57 pv. undulosa placed genotypes 1 to 8, and...

Tumorigenic agrobacteria—members of the bacterial family Rhizobiaceae —cause crown gall and hairy root diseases on a broad range plant species. These bacteria are responsible for economic losses in nurseries important fruit trees ornamental plants.

Bacterial leaf streak disease caused by Xanthomonas translucens pv. undulosa is an economically important threatening wheat and barley crops around the globe. Thus far, specific PCR-based detection identification tests for X. pathovars are not available. In this study, we used comparative genomics approach to design a pathovar-specific primer pair of in naturally infected seeds its differentiation from other species. For aim, complete genome sequences strains different were compared PCR...

ABSTRACT Fruit bodies (sporocarps) of wild mushrooms growing in natural environments play a substantial role the preservation microbial communities, for example, clinical and food-poisoning bacteria. However, as reservoirs plant pathogenic bacteria remains almost entirely unknown. Furthermore, bacterial transmission from mushroom species to agricultural plants has rarely been recorded literature. In September 2021, creamy-white Gram-negative strain was isolated sporocarp Suillus luteus...
