Acacia koa seedlings were evaluated from plantings and commercial nurseries for colonization by Fusarium spp., particularly F. oxysporum, the putative cause of koa wilt/dieback disease in Hawaii. We sampled 162 seedlings, 90% of which were from nurseries on the islands of Hawaii, Maui, Kauai, and Oahu. Fusarium oxysporum was detected on about 78% of sampled seedlings. It was most prevalent on r...
Fusarium is a genus of filamentous fungi that contains many agronomically important plant pathogens, mycotoxin producers, and opportunistic human pathogens. Comparative analyses have revealed that the Fusarium genome is compartmentalized into regions responsible for primary metabolism and reproduction (core genome), and pathogen virulence, host specialization, and possibly other functions (adap...
Pathogenic isolates of Fusarium oxysporum, distinguished as formae speciales (f. spp.) on the basis of their host specificity, cause crown rots, root rots and vascular wilts on many important crops worldwide. Fusarium oxysporum f. sp. cepae (FOC) is particularly problematic to onion growers worldwide and is increasing in prevalence in the UK. We characterized 31 F. oxysporum isolates collected ...
Guava (Psidium guajava L.) is an important fruit crop of subtropical countries and cultivated extensively throughout India, it is grown almost in all the states. Bihar has the largest area (24.7 thousand ha.) under guava cultivation followed by Uttar Pradesh (18.5 thousand ha.) and Maharastra (14.8 thousand ha.). Various pathogens have been reported from the wilt affected plants from guava orch...
Our group studies tomato foot and root rot, a plant disease caused by the fungus Forl (Fusarium oxysporum f.sp. radicis-lycopersici ). Several bacteria have been described to be able to control the disease, using different mechanisms. Here we describe a method that enables us to select, after application of a crude rhizobacterial mixture on a sterile seedling, those strains that reach the root ...
The antifungal activity of zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles prepared by bio-safe method was evaluated for Alternaria alternate, Fusarium oxysporum, Rhizopus stolonifer and Mucor plumbeus. It was observed from the study that all the nanoparticles at different concentrations brought about significant inhibition in the germination of spores of Alternaria alternata, Fusarium...
The antifungal activity of extracts of Tinospora cordifolia (leaves), Moringa oleifera (bark) and Trachyspermum ammi (seeds) at three concentrations viz., 25, 50, 75% (v/v) were evaluated in vitro by poisoned food technique against Fusarium oxysporum f. sp. lycopersici and Fusarium solani causing wilt disease on tomato and brinjal plants. The antifungal activity was assessed in terms of percent...
In this paper, we for the first time show the ability of the mesophilic fungus Fusarium oxysporum in the bioleaching of waste material such as Fly-ash for the extracellular production of highly crystalline and highly stable, protein capped, fluorescent and water soluble silica nanoparticles at ambient conditions. When the fungus Fusarium oxysporum is exposed to Fly-ash, it is capable of selecti...
In this study Dodecyl trimethyl ammonium sulphate (DTA) was obtained through quaternization reaction between dodecylamine and dimethyl sulfate (yield: 51.5%) while Dimethylamino propyl glucosylamine (DAPGA) was successively synthesized from D-glucose and 3-Dimethylamino propylamine (yield: 93.6%). Both compounds were analyzed through NMR spectroscopy. Evaluation of their biological activity aga...
As the world’s food safety and environmental problems become increasingly severe, agricultural sectors of various countries are also paying closer attention to use biofertilizers biocontrol agents. Rhizosphere bacteria a significant source commonly used This study aims describe genome genomic traits agent in genus Bacillus. In this paper, strain Bacillus amyloliquefaciens IBFCBF-5 was isolated ...
