“…For Y. pestis, Y. pseudotuberculosis, and X. nematopila, biofilm development on the nematodes is dependent upon the hmsHFRS gene cluster [130,132]. The DF41 genome harbours a homologous operon, with a high degree of similarity at the amino acid level to PgaABCD of Pseudomonas fluorescens [9]. The PgaABCD biosynthetic cluster is conserved in 19 of the 21 P. brassicacearum strains (Fig.…”

“…Interestingly, differences in the reduction of nitrate and hydrolysis of gelatin and Tween 80 occurred between fluorescent and non-fluorescent variants [5]. These bacteria were also classified as non-pectinolytic and produced no hypersensitivity response on tobacco, which is not surprising since P. brassicacearum isolates are primarily studied for their beneficial effects [3,[5][6][7][8][9][10][11][12][13][14][15].…”

“…The remarkable mutual affinity between P. brassicacearum and wheat allows bacterial populations to reach the density required for disease control [8,11]. Since the type strain was first reported two decades ago [5], several isolates from the rhizosphere of plants have been described [5,16,176,7,9,10,14,15,18]. P. brassicacearum strains isolated from Arabidopsis, canola, potato, strawberry, tomato, and agricultural soils across a large geographic area also demonstrate exceptional biocontrol capabilities [5-7, 9, 10, 14, 15].…”

“…There are currently no metadata associated with BS3663 and to the best of our knowledge, there are no peer-reviewed publications available on this or strain 51MFCVI2.1. The second group includes DF41, a well-characterized biocontrol isolate from canola root [22,23,9,24,25], as well as two strains isolated from Wyoming soil, 36B7 and 36D4 which have high (98.3 and 98.5 %) pairwise amino acid identities (AAIs) with DF41 [20]. Two other soil isolates from Wyoming, 38D4 and 38D7, form the third group, while the fourth group consists of 37D10 and 48H11, isolated from soils in Wyoming and Wisconsin, respectively.…”

Pseudomonas brassicacearum is one of over fifty species of bacteria classified into the P. fluorescens group. Generally considered a harmless commensal, these bacteria are studied for their plant-growth promotion (PGP) and biocontrol characteristics. Intriguingly, P. brassicacearum is closely related to P. corrugata , which is classified as an opportunistic phytopathogen. Twenty-one P. brassicacearum genomes have been sequenced to date. In the current review, genomes of P. brassicacearum and strains from the P. corrugata clade were mined for regions associated with PGP, biocontrol and pathogenicity. We discovered that ‘beneficial’ bacteria and those classified as plant pathogens have many genes in common; thus, only a fine line separates beneficial/harmless commensals from those capable of causing disease in plants. The genotype and physiological state of the plant, the presence of biotic/abiotic stressors, and the ability of bacteria to manipulate the plant immune system collectively contribute to how the bacterial-plant interaction plays out. Because production of extracellular metabolites is energetically costly, these compounds are expected to impart a fitness advantage to the producer. P. brassicacearum is able to reduce the threat of nematode predation through release of metabolites involved in biocontrol. Moreover this bacterium has the unique ability to form biofilms on the head of Caenorhabditis elegans, as a second mechanism of predator avoidance. Rhizobacteria, plants, fungi, and microfaunal predators have occupied a shared niche for millions of years and, in many ways, they function as a single organism. Accordingly, it is essential that we appreciate the dynamic interplay among these members of the community.

Biological control of the soil-borne fungal pathogen Sclerotinia sclerotiorum –– a review

2018

View full text Add to dashboard Cite

Diseases caused by Sclerotinia sclerotiorum (Lib) de Bary are difficult to control and cause increasing losses of horticultural crops worldwide. Reasons of this phenomenon are various: (i) the specialization of crop production that causes the accumulation of the pathogen in the soil; (ii) the lack of a safe and efficient method of soil fumigation; (iii) the specific life cycle of S. sclerotiorum with survival structures (sclerotia), resistant to chemical and biological degradation. Sclerotinia diseases depend on many environmental factors which determine sclerotia survival and ascospores dissemination, because plants are mainly infected by air-borne ascospores from carpogenic germination of sclerotia. Due to the lack of effective synthetic agents for eradication of S. sclerortiorum from soil considerable interest has been focused on biological control, especially the selection of microorganisms with mycoparasitic activity towards S. sclerotiorum sclerotia, that can decrease their number in the soil. In this work we review reports on the use of different antagonistic fungi and bacteria in the control of S. sclerotiorum and discuss the suppressive effect of organic amendments against this soil-borne pathogen.

Microbial natural products among other functions they play a vital role in the disease prevention in humans, animals and plants. Pseudomonas parafulva CRS01‐1 is a broad‐spectrum antagonistic bacterium present in plants. However, no natural products have been isolated from this strain till date. Corresponding biosynthetic gene clusters to natural products is an effective method for bioprospecting, for which, genome manipulation tools are essential. We previously developed Pseudomonas‐specific phage‐derived homologous recombination systems for genetic engineering in four Pseudomonas species. Herein, we report the application of these recombineering systems in Pseudomonas parafulva CRS01‐1, along with structural elucidation and bioactivity evaluation of natural products. The Pseudomonas recombineering toolbox established before in different four species is efficient for genome mining and bioactive metabolite discovery from more distant species.
