OBJECTIVE To find anti-phytopathogen compounds from endophytic fungi associated with the endangered species Heptacodium miconioides. METHODS Fungi from H. miconioides with antifungal activities were isolated according to the plate growth inhibition method. The fungus with preferable antifungal activities was identified by morphological identification and 5. 8S rRNA sequence analysis. The bioa...

Antifungal activity of water soluble exudates of pea leaves was assayed. Exudates of different nodal leaves were collected by dipping them in sterilized distilled water for different length of time and conidial germination of four non-pathogenic to pea fungi (Alternaria solani, Curvularia lunata, Helminthosporium penniseti and H. echinocloa) and one pea pathogenic to pea fungus (Erysiphe pisi) ...

Effect of aqueous leaf extracts of 8 allelopathic tree species viz., Accacia nilotica (L.) Willd ex Del., Alstonia scholaris (L.) R. Br., Azadirachta indica (L.) A. Juss., Eucalyptus citriodora Hook, Ficus bengalensis L., Mangifera indica L., Melia azedarach L. and Syzygium cumini (L.) Skeels was studied on germination and seed-borne mycoflora of wheat (Triticum aestivum L.). Wheat seeds were s...

The study was conducted over the years 2012-2013 in order to evaluate the antagonistic effects of the metabolites of actinomycetes against phytopathogenic fungi of agricultural importance. To demonstrate the antagonist activity of antibiosis, bioassays were performed in vitro using the method of wells with cell-free filtrates and the double layer method with chloroform in order to kill living c...

Seven seed borne fungi were isolated from sugar beet seeds viz. Alternaria alternata, Helminthosporium sp., Rhizopus stolonifer, Epicoccum sp., Rhizoctonia solani, Phoma betae and Fusarium oxysporium f. sp. betae. The last three fungi were found internal, while the others were external on seed surface. The internal fungi caused root-rot disease to sugar beet plants. Tre11tment of seeds with eac...

• Potato (Solanum tuberosum) calcium-dependent protein kinase (StCDPK5) has been shown to phosphorylate the N-terminal region of plasma membrane RBOH (respiratory burst oxidase homolog) proteins, and participate in StRBOHB-mediated reactive oxygen species (ROS) burst. The constitutively active form, StCDPK5VK, provides a useful tool for gain-of-function analysis of RBOH in defense responses. • ...

Botanicals obtained from the plants are well known for suppression of inimical plant pathogens. The present study explores efficacy five locally available extracts their antifungal activity against early blight potato incited by Alternaria solani. include Datura stramonium, Allium sativum, Azadirachta indica, Eucalyptus globulus, and Lantana camara. All reduced mycelial growth conidial germinat...

Chitinases have the ability of chitin digestion that constitutes a main compound of the cell wall in many of the phytopathogens such as fungi. In the following investigation, a novel chitinase with antifungal activity was characterized from a native Serratia marcescens B4A. Partially purified enzyme had an apparent molecular mass of 54 kDa. It indicated an optimum activity in pH 5 at 45°C. Enzy...
