The grapevine trunk diseases (GTD) Botryosphaeria dieback and esca threaten the sustainability of industry worldwide. This study aimed to evaluate compare efficacy various liquid (pyraclostrobin + boscalid thiophanate methyl) paste (paste tebuconazole) formulation fungicide treatments as well biological control agents (Trichoderma atroviride SC1 T. I-1237), for their potential prevent infection...

Global-scale data on the Oligocene to Recent planktic foraminifers and coccoliths from the tropical Pacific and Atlantic Oceans are employed for quantitative testing of alternative models (Red Queen and Stationary Hypotheses) of the relationship between speciation rates, extinction rates, taxonomic diversity, abiotic events, and history of the paleosystem. The results demonstrate that although ...

<i>Psidium guajava</i> leaf paste and decoction have long been used in Mauritius for their efficacy dandruff management. The study aimed to test <i>P. extracts against fungi collected from patients' scalps, as previous research has shown a strong link between dermatophytes. Fungi were isolated cultured on Sabouraud dextrose agar (SDA), which contained 2% olive oil, 1% Tween 80...

In this study Trichoderma atroviride was selected as over producer of chitinase enzyme among 30 different isolates of Trichoderma sp. on the basis of chitinase specific activity. From this isolate the genomic and cDNA clones encoding chit33 have been isolated and sequenced. Comparison of genomic and cDNA sequences for defining gene structure indicates that this gene contains three short introns...

Plants are constantly exposed to microbes, for this reason they have evolved sophisticated strategies to perceive and identify biotic interactions. Thus, plants have large collections of so-called resistance (R) proteins that recognize specific microbe factors as signals of invasion. One of these proteins is codified by the Arabidopsis thaliana HR4 gene in the Col-0 ecotype that is homologous t...

BACKGROUND There is an imperative necessity for alternative sources of energy able to reduce the world dependence of fossil oil. One of the most successful options is ethanol obtained mainly from sugarcane and corn fermentation. The foremost residue from sugarcane industry is the bagasse, a rich lignocellulosic raw material uses for the production of ethanol second generation (2G). New cellulol...
