Control of Fusarium verticillioides,cause of ear rot of maize,by Pseudomonas fluorescens

BACKGROUND: Maize is one of the staple food crops grown in India. Fusarium verticillioides (Sacc.) Nirenberg is the most important fungal pathogen of maize, associated with diseases such as ear rot and kernel rot. Apart from the disease, it is capable of producing fumonisins, which have elicited considerable attention over the past decade owing to their association with animal disease syndromes. Hence, the present study was conducted to evaluate ecofriendly approaches by using a maize rhizosphere isolate of Pseudomonas fluorescens (Trev.) Mig. and its formulation to control ear rot disease and fumonisin accumulation, and also to study the capacity to promote growth and yield of maize. In vitro assays were conducted to test the efficacy of P. fluorescens as a seed treatment on seed germination, seedling vigour and also the incidence of F. verticillioides in different maize cultivars. The field trials included both seed treatment and foliar spray. For all the experiments, P. fluorescens was formulated using corn starch, wheat bran and talc powder. In each case there were three different treatments of P. fluorescens, a non‐treated control and chemical control. RESULTS: Pure culture and the formulations, in comparison with the control, increased plant growth and vigour as measured by seed germination, seedling vigour, plant height, 1000 seed weight and yield. P. fluorescens pure culture used as seed treatment and as spray treatment enhanced the growth parameters and reduced the incidence of F. verticillioides and the level of fumonisins to a maximum extent compared with the other treatments. CONCLUSION: The study demonstrates the potential role of P. fluorescens and its formulations in ear rot disease management. The biocontrol potential of this isolate is more suited for fumonisin reduction in maize kernels intended for human and animal feed. Copyright © 2009 Society of Chemical Industry  相似文献   

Effect of Protein Hydrolysates from Germinated Soybean on Cancerous Cells of the Human Cervix: An <Emphasis Type="Italic">In Vitro</Emphasis> Study     

R. Mora-Escobedo  Maria del Carmen Robles-Ramírez  Eva Ramón-Gallegos  Rafael Reza-Alemán 《Plant foods for human nutrition (Dordrecht, Netherlands)》2009,64(4):271-278

Consumption of soybeans can reduce the risk of different types of cancer. Little is known about the effect of germination on the anticancer properties of soya. This study was done to determine if germination improves the anticancer properties of soybean protein through generation of amino acids or bioactive peptides. Soybean was germinated for 0, 2, 3, 4, 5, and 6 days and proteins were isolated from the seeds. Isolates with and without ethanol-soluble phytochemicals were hydrolyzed with digestive enzymes and their effect on growth in HeLa and C-33 (epidermoid cervical carcinoma) and HaCaT (non-cancerous human keratinocytes) cells were evaluated with the Alamar Blue method. Germination induced degradation of the α and α’ fractions of β-conglycinin and acid fraction of glycinin, generating low molecular weight peptides. Degrees of hydrolysis ranged from 73–77%. Hydrolysates inhibited the growth of HeLa cells and C-33 at concentrations exceeding 1.25 mg/ml. Major inhibition was observed with the hydrolysate germinated for 2 days and containing ethanolsoluble phytochemicals (IC₅₀ 2.15 and 2.27 mg/ml for HeLa and C-33, respectively). Interestingly, hydrolysate cytoxicity for normal cells was minimal in comparison to cancer cells.  相似文献

Oxidation of dietary polyphenolics by hydroperoxidase activity of lipoxygenase     

Pinto Mdel C  Macias P 《Journal of agricultural and food chemistry》2005,53(23):9225-9230

Lipoxygenase, in the presence of hydrogen peroxide, produces the oxidative decomposition of quercetin, naringenin, and resveratrol, known antioxidant molecules. Quercetin was the molecule more efficiently oxidized, followed by resveratrol and naringenin. When this molecule was incubated in the presence of GSH, a quinoid derivative was produced. This compound was not obtained in the presence of naringenin or resveratrol, suggesting that in the presence of hydrogen peroxide and lipoxygenase, quercetin may be oxidized to a prooxidant species. When hydrogen peroxide was substituted by hydroperoxy linoleic acid, the same oxidative process was observed. This means that in food products in which lipoxygenase and linoleic acid are presents, quercetin may be oxidized to prooxidant species; in contrast, naringenin and resveratrol may constitute a valid additive for the prevention of the oxidative degradation of foods.  相似文献   

Feline uveitis: diagnosis and treatment     

Colitz CM 《Clinical Techniques in Small Animal Practice》2005,20(2):117-120

Uveitis is the inflammation of any or all parts of the vascular tunic of the eye; the vascular tunic includes the iris, the ciliary body, and choroid. A good knowledge base, up-to-date reference materials, and good instruments will improve the diagnosis of uveitis. Feline uveitis can be caused by numerous infectious agents in addition to neoplasia and less likely trauma. The infectious causes most commonly associated with feline uveitis include feline leukemia virus, feline immunodeficiency virus, feline infectious peritonitis, systemic fungal infections, toxoplasmosis, and bartonellosis. Neoplastic causes of uveitis can be primary or secondary. Iris melanoma is the most common primary uveal neoplasia and trauma-associated sarcoma is the second most common primary uveal neoplasia. Treatment for the clinical signs of anterior uveitis include topical steroidal or non-steroidal anti-inflammatory agents, parasympatholytic agents for ciliary spasm, to keep the pupil dilated, and to prevent posterior synechia. Posterior uveitis should be treated with systemic medications that will address the underlying cause. Enucleation of blind, painful eyes not responsive to medications is a means to alleviate the animal's discomfort and to further diagnose the underlying cause.  相似文献
