Abstract Twenty‐two strains of Pseudomonas fluorescens isolated from the rhizosphere soil nine plant species were screened in vitro for their inhibitory effect on mycelial growth rice sheath blight fungus, Rhizoctonia solani . Of 22 strains, two promising (Pf1 and FP7) assessed seedling vigour ability to promote four cultivars rice. Both bacterial induced systemic resistance cv. IR 50, which is susceptible blight. After inoculation sheaths with pathogen, ‐treated plants showed an increase...
Abstract Strains of Pseudomonas fluorescens were investigated for biocontrol efficacy against tomato spotted wilt virus (TSWV) in both alone and mixtures. P. strains applied to seed, soil foliage or as a seedling dip significantly reduced TSWV, with concomitant increase growth promotion the glasshouse field. Two native (CoP-1 CoT-1) one foreign strain (CHAO) TSWV. In fluorescens-treated plants, increased activity polyphenol oxidase, β-1,3-glucanase chitinase was observed, induction confirmed...
Basal stem rot (BSR) caused by the species of Ganoderma is one most devastating diseases numerous perennial, coniferous and palmaceous hosts. In forest systems, has an ecological role in breakdown or delignification woody plants. Symptoms BSR disease can take several years to develop, presence pathogen (such as indicated fruiting bodies) often only visible when fungus well established more than half bole tissue been decayed, leaving no chance for grower cure infected palms. Soils with poor...
Plant growth-promoting bacteria (PGPB) include isolated from rhizosphere, phyllosphere, marine, rock surface, and different ecosystems. PGPB enhance plant growth by promoting nitrogen fixation, phosphorus solubilization, production of phytohormones such as indole acetic acid (IAA), gibberellins, polyamines, nitric oxide, stress-mitigating enzyme viz., 1-aminocyclopropane-1-carboxylate deaminase. Further, they protect health through the synthesis antibiotics hydrolytic enzymes induction...
Bacillus subtilis is a Gram-positive bacterium known for its antagonistic attributes, particularly through the production of various secondary metabolites, including lipopeptides. In this study, we investigated capabilities B. strain NBAIR-BSWG1 with focus on assessing efficacy in combatting Sclerotium rolfsii. Our findings demonstrated substantial inhibitory effects, 82.73% to 100% reduction S. rolfsii growth when exposed at concentrations ranging from 50 100 µL/mL poison food technique....
Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae), is an economically important invasive cassava pest responsible for the massive devastation of in Asia and African continent. Initially, identifying this posed challenges because it closely resembled native mealybug species. Additionally, traditional morphological identification process labor-intensive time-consuming. Detecting pests at early stage crucial, hence development a rapid detection assay essential. In current study,...
Abstract Background Melon fruit fly, Zeugodacus cucurbitae Coquillett (Diptera: Tephritidae), is a devastating polyphagous pest attacking large number of fruits and vegetables causing huge economic yield losses across the world. Management this notorious very challenging as larvae feed inside fruit. Hence, present research study aimed to screen indigenous Bacillus thuringiensis Berliner (Bacillales: Bacillaceae) strains toxicity identify insecticidal toxicity-related genes in respective...
Abstract Background Among all the coconut pests, rhinoceros beetle causes acute and serious damage to palm. Management of this pest is very difficult due its nocturnal activity, also, it damages emerging leaf inside bud. using entomopathogens will be great importance as economical ecofriendly. Studies were carried out decipher biocontrol potential indigenous entomopathogenic bacterium ( Bacillus thuringiensis ) fungi Metarhizium robertsii M. majus against Oryctes in field, individually well...
Abstract Background Several Echinacea species have been used as nutraceuticals or botanical drugs for "immunostimulation", but scientific evidence supporting their therapeutic use is still controversial. In this study, a phytocompound mixture extracted from the butanol fraction (BF) of stem and leaf (S+L) extract E. purpurea ([BF/S+L/Ep]) containing stringently defined bioactive phytocompounds was obtained using standardized published procedures. The transcriptomic proteomic effects...
Abstract Background Shikonin, a phytochemical purified from Lithospermum erythrorhizon , has been shown to confer diverse pharmacological activities, including accelerating granuloma formation, wound healing, anti-inflammation and others, is explored for immune-modifier activities vaccination in this study. Transdermal gene-based vaccine an attractive approach delivery of DNA transgenes encoding specific tumor antigens host skin tissues. Skin dendritic cells (DCs), potent antigen-presenting...
Alternaria alternata wreaks havoc on fruit and vegetable production globally, threatening food security by causing black leaf spot disease. Bacillus subtilis, a natural inhabitant of soil, is promising biological control agent for the management A. alternata. In present study, antagonistic potential B. subtilis NBAIR-BSWG1 was initially confirmed against through dual culture technique with 43.03% inhibition mycelial growth. Subsequently, we extracted cell-free extract from pure assessed its...
Abstract Background Porcine circovirus type 2 (PCV2) is the primary cause of an emerging swine disease, postweaning multisystemic wasting syndrome, that responsible for economic losses. To develop effective vaccine PCV2, we evaluated a heterologous prime‐boost approach, using gene gun‐mediated naked DNA vector as priming and modified vaccinia virus ankara (MVA) booster, in Balb/c mice. Methods Three open reading frames (ORF) PCV2 viral samples from infected pigs were amplified, vaccination...
Specific cytokines have been tested clinically for immunotherapy of cancers; however, cytotoxicity has often impaired their usefulness. Consequently, alternative approaches are increasingly desirable. Dioscorea spp. tuber is a widely used traditional Chinese medicinal herb claimed to confer immunostimulatory activity. In this study, we evaluated as an adjuvant therapy use alongside chemotherapy cancer. Phytocompounds from tubers were ethanol fractioned and ex vivo splenocyte proliferation...
