The mushroom Pleurotus ostreatus has nutritional and medicinal characteristics that depend on the growth substrate. In nature, this fungus grows dead wood, but it can be artificially cultivated agricultural wastes (coffee husks, eucalyptus sawdust, corncobs sugar cane bagasse). degradation of involves some enzyme complexes made up oxidative (laccase, manganese peroxidase lignin peroxidase) hydrolytic enzymes (cellulases, xylanases tanases). Understanding how these work will help to improve...

The elimination of antinutritional factors the Jatropha curcas L. seed cake is important for decreasing environmental damage and adding economic value to this residue biodiesel industry. In study, we analyzed ability Pleurotus ostreatus degrade produce edible mushrooms using different proportions J. as substrate. After 60 d incubation at 25 °C, observed 95% phytic acid 85% tannins reductions, high productivity. There was no evidence or in these mushrooms. Furthermore, phorbol ester...

Plant RBOH (RESPIRATORY BURST OXIDASE HOMOLOGS)-type NADPH oxidases produce superoxide radical anions and have a function in developmental processes response to environmental challenges. Barley RBOHF2 has diverse reported functions interaction with the biotrophic powdery mildew fungus Blumeria graminis f. sp. hordei. Here, we analyzed, detail, plant leaf level- age-specific susceptibility of stably RBOHF2-silenced barley plants. This revealed enhanced fungal penetration young tissue but...

In nature, orchid seeds obtain the nutrients necessary for germination by degrading intracellular fungal structures formed after colonization of embryo mycorrhizal fungi. Protocols asymbiotic typically use media with high concentrations soluble carbohydrate and minerals. However, when reintroduced into field, seedlings obtained via have lower survival rates than do symbiotic germination. Tree fern fiber, ideal substrate seedling acclimatization, is increasingly scarce. Here, we evaluated...

Manganese (Mn) toxicity is a very common soil stress around the world, which responsible for low fertility. This manuscript evaluates effect of endophytic bacterium Pseudomonas sp. Q1 on different rhizobial-legume symbioses in absence and presence Mn toxicity. Three legume species, Cicer arietinum (chickpea), Trifolium subterraneum (subterranean clover), Medicago polymorpha (burr medic) were used. To evaluate role 1-aminocyclopropane-1-carboxylate (ACC) deaminase produced by strain these...

The detoxification of Jatropha curcas seed cake is major interest for the biodiesel industry to add economic value this residue and also reduce environmental damage caused by its inappropriate disposal. In context, treatment with white rot fungus, Pleurotus ostreatus, can be a viable alternative because it produces enzymes capable degrading different lignocellulosic residues toxic compounds. study, capacity P. ostreatus degrade phorbol esters found in potential transform animal feed was...

Na natureza, as espécies de Orchidaceae estão associadas a fungos micorrízicos. A compreensão da especificidade fungo-planta nessa associação pode auxiliar no desenvolvimento programas para propagação simbiótica das orquídeas. Fungos micorrízicos Epulorhiza spp. têm sido isolados Epidendrum secundum Jacq. com maior freqüência. Assim, o objetivo deste trabalho foi avaliar germinação sementes e protocormos E. associados diferentes do gênero Epulorhiza. Utilizou-se 16 populações secundum. Após...

Gladiolus (Iridaceae) is a popular bulbous plant grown worldwide as an ornamental garden or cut flower due to its attractive color, size, and shape. In April 2012, leaf spots were observed on plants of grandiflorus varieties T-704 Amsterdam growing in production area flowers located the city Viçosa, Minas Gerais. The oval round brown with dark border surrounded by halo yellow tissue. Infected samples deposited herbarium at Universidade Federal de Viçosa (VIC31897). A fungus was isolated from...

In this study the susceptibility of different genotypes gladiolus (Gladiolus callianthus and G. grandiflorum T-704, Red Beauty, Tradehorn, Verônica, Amsterdam, Yester Gold, Rose Friendship) was evaluated correlated with development Curvularia gladioli infective structures. The plants were inoculated a 3 x 10(4) conidial suspension pathogen, severity infection assessed eight days after inoculation. Leaf samples vars. T-704 collected 24 hours They cleared rates spore germination appressorium...

The use of Jatropha curcas as a raw material for biodiesel production results in large amounts solid residue called seed cake (Jc). This is composed lignin, cellulose, toxic compounds and anti-nutritional factors. Though the monomers that make up lignin tannins could be used animal feed, polymer forms are not easily digestible, which necessitates processing step. White rot fungi known to produce enzymes capable degrading these polymers, well factors some (for example, phorbol ester)....

Homologs of qseG gene (coding for the membrane protein QseG), along with qseEF genes, are present in many Enterobacteriaceae; however, its role non-pathogenic strains is still unknown. To fill this knowledge gap, we investigated QseG a plant-associated enterobacterium interactions legume host and benefits induced by Mesorhizobium–chickpea symbiosis. Here, showed that Kosakonia sp. MH5 involved following processes: (i) evasion plant immune system (ii) efficient colonization chickpea root...
