To improve sorghum for bioenergy and forage uses, brown midrib (bmr)6 and -12 near-isogenic genotypes were developed in different sorghum backgrounds. The bmr6 and bmr12 grain had significantly reduced colonization by members of the Gibberella fujikuroi species complex compared with the wild type, as detected on two semiselective media. Fusarium spp. were identified using sequence analysis of a...

The molecular mechanisms underlying the initiation of innate and adaptive proallergic Th2-type responses in the airways are not well understood. IL-33 is a new member of the IL-1 family of molecules that is implicated in Th2-type responses. Airway exposure of naive mice to a common environmental aeroallergen, the fungus Alternaria alternata, induces rapid release of IL-33 into the airway lumen,...

Potato brown spot caused by Alternaria alternata (Fr.) Keissler is one of the most destructive diseases potato worldwide. The present study was conducted to identify causal agent, and test efficacy several fungicides with different modes actions against A. alternata. Five chemical including; Copper oxychloride (Sufer Oxychloride® 50% WP), Carbendazim (Carbendazim Aria® 60% Penconazole (Penconaz...

Fungal species were isolated from samples of damaged sunflower. The strains selected on the basis cultural and morphological characteristics belonged to Alternaria alternata, tennus Fusarium oxysporum, solan , fungal identified, as well strains, 67, termites, termarium, oxolbate 10, oxoliban 10 - 10.9%.

IL-9 overexpression protects against alveolar fibrosis induced by crystalline silica particles. This cytokine is also involved in allergic asthma. In the present study, we examined the effect of IL-9 overexpression on the subepithelial fibrotic response, a feature of asthmatic remodeling, induced by chronic exposure to Alternaria alternata extract. IL-9-overexpressing mice (Tg5) and their wild-...

O -Alkyl derivatives of naringenin ( 1a - 10a ) were prepared from naringenin using the corresponding alkyl iodides and anhydrous potassium carbonate. The resulting products were used to obtain oximes ( 1b - 10b ). All compounds were tested for antimicrobial activity against Escherichia coli ATCC10536, Staphylococcus aureus DSM799, Candida albicans DSM1386, Alternaria alternata CBS1526, Fusariu...

The Alternaria brown spot (ABS) is a disease caused in tangerine plants and its hybrids by the fungus Alternaria alternata f. sp. citri which has been found in Brazil since 2001. Due to the recent occurrence in Brazilian orchards, the epidemiology and genetic variability of this pathogen is still an issue to be addressed. Here it is presented a survey about the genetic variability of this fungu...

Several fungal endophytes were isolated from some medicinal plants and screened for their ability to produce the anticancer drug vinblastine. An isolate was found vinblastine (205·38 ?g l?1), identity of confirmed by UV spectroscopic, high?performance liquid chromatography electrospray ionization mass spectrometry analyses. Based on both morphological molecular studies, vinblastine?producing st...
