Introduction Fusarium wilt of bananas ( Musa spp.), a threat to sustainable banana production worldwide, necessitates immediate action control the disease. The current strategies are centered on preventing its spread or developing resistant varieties. However, very little is known about genetic machinery used by fungus infect and kill plants. Therefore, research should focused also in understanding plant-pathogen molecular interaction targeting virulent genes for knock-out Fusarium. This...
The xylanolytic potential of endophytic fungi isolated from leaves Theobroma cacao was explored for the first time. Four fungal strains showed significant amounts xylanase activity and low cellulase levels when grown on wheat bran as sole carbon source. Strain Ec220 Fusarium graminearum had highest production (1.79 U/ml), whereas its minimal (0.24 U/ml). Optimal conditions were: 154 h incubation time, pH 5.79 29.8 °C. Furthermore, two protein spots detected by two-dimensional gel...
ABSTRACT The dispersed gene family 1 ( DGF-1 ) is the fifth largest in T rypanosoma cruzi genome, with over 500 members (11). Many of predicted protein products have several transmembrane domains and N - glycosylation phosphorylation sites were thought to localize plasma membrane. Here, we report that affinity-purified antibodies against a region one these proteins (DGF-1.2) localized it intracellularly different stages parasite. DGF-1.2 more abundant amastigote stage than trypomastigotes...
Fusarium wilt of Banana (FWB) caused by oxysporum f. sp. cubense (Foc) poses a significant threat to the banana industry, with current inadequate control measures. This study evaluated antifungal potential nine Streptomyces strains isolated from Antarctic soil samples, using Casein-Starch media stimulate production compounds. The inhibition spectrum against Foc was assessed under laboratory conditions well diffusion on Mueller-Hinton agar, activity measured in arbitrary units (AU/mL) and...
Sugar beet pulp (SBP) is a waste product of the sugar industry which rich in ferulic acid. Few acid esterases (FAEs) that are capable releasing from SBP or soluble feruloylated oligosaccharides (SFO-SBP) have been described. Streptomyces avermitilis CECT 3339 was grown medium containing destarched wheat bran (DSWB) as carbon source. FAE activity evaluated terms micro-organism's capacity to release DSWB, SBP, SFO-DSWB and SFO-SBP. S showed both media able A comparison detected each indicated...
Vitellogenins (Vtg) are glycolipophosphoproteins synthesized by oviparous vertebrates as yolk proteins precursors.These have been studied for their role in reproduction and endocrine disruption.In this work, we report the first proteomic study towards characterization of Vtg from Pseudoplatystoma fasciatum, Piaractus brachypomus Colossoma macropomum.Male specimens each three fish species were estradiol-induced (experimental) non-induced (control).The initial was made 2D protein gel...
In Peru, 5 of every 10 children suffer from malnutrition, which increases the risk developing non-communicable diseases (NCDs) at early stages their life. Sacha inchi (Plukenetia huayllabamana) cake is by-product oil extraction process Amazon Peruvian seed and has high protein (56%) fiber (5.9%) content. Tarwi (Lupinus mutabilis Sweet) a legume characterized by its content (>50%) levels tyrosine tryptophan amino acids. Thus, purpose this research was to develop high-protein cookies enriched...
Ecuador es uno de los principales exportadores banano a nivel mundial, razón por la cual vital demostrar las garantías necesarias en cuanto al manejo adecuado esta fruta. Fusarium tropical raza 4 (TR4), amenaza con desaparecer cultivares Cavendish, lo que investigación se centró realizar el diseño 2 sgRNA primer exón secuencia target estudio, perteneciente familia genes SIX (Secreted In Xylem) y provocar una deleción in vitro través tecnología CRISPR Cas9, ya presume dicho gen está...
The present study used proteomics to analyze the expression of lectin-like proteins, specifically arcelins, in P. vulgaris cultivar varieties from Venezuela. A PAGE-SDS analysis 30 commercial accessions showed significant differences molecular weight range proteins (arcelins). Eight different were selected based on their electroforetic mobility for proteomic analysis. Arcelin immuno-detection two dimentional electrophoresed was easily display arcelin profiles studied accessions. Mass...
Although kernel infection by Aspergillus flavus and pre-harvest aflatoxin contamination of Zea mays grain is a significant crop production problem, not only in Venezuela but also around the world, little progress has been made identifying proteins metabolic pathways associated with this pathogen resistance. Usually, protein two-fold expression between control condition considered biomarker some phenomena, we think it essential to evaluate its contribution That why decided determine...
