Magnaporthe oryzae, the causative pathogen of rice blast, has caused extensive losses to rice cultivation worldwide. Strains of the bacterium Bacillus subtilis have been used as biocontrol agents against rice blast. However, little has been reported about the interaction between B. subtilis and the rice plant and its mechanism of action. Here, the colonization process and induced disease resist...
Anthracnose disease can be successfully controlled by chemical pesticides in conventional fruit growing. However, organic farming, order to maintain environmental safety and fulfill consumer demand for pesticide-free food, the control of this is a major problem. The use biocontrol agents with antagonistic mechanism many phytopathogens an innovative alternative cost-effective eco-friendly produc...
this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
bacillus subtilis k40b was isolated from rice rhizospheres and its potential for production of xylanase was evaluated using biochemical methods. the gene for xylanase in b. subtilis k40b was amplified, sequenced and assigned to the ncbi genebank. the gene size was estimated to be 563 bp encoding 413 amino acids. comparison of the xylanase gene with reference sequences showed that the xylanase o...
Abstract Sclerotinia stem rot caused by sclerotiorum is one of the most important diseases oilseed rape in world. Because absence resistant varieties and disadvantages chemical control, application antifungal microbes has become an eco-friendly effective measure to control this disease. In study, Bacillus subtilis strain RSS-1, isolated from soil samples, was identified based on morphological, ...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
The root-knot nematodes Meloidogyne incognita poses a serious threat to horticultural food and plantation crops. One of the effective efficient measures overcome this nematode is using bacteria as biological control agent. This study aimed test effectiveness Bacillus subtilis grown on media with additional micronutrients agent for M. incognita. was carried out by growing in 100 mL nutrient brot...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
BACKGROUND Bacillus subtilis is a favorable host for the production of industrially relevant proteins because of its capacity of secreting proteins into the medium to high levels, its GRAS (Generally Recognized As Safe) status, its genetic accessibility and its capacity to grow in large fermentations. However, production of heterologous proteins still faces limitations. RESULTS This study aim...
Eight strains of highly amylolytic, sporeforming bacilli (hereafter referred to as Bacillus amyloliquefaciens) were compared with respect to their taxonomic relationship to B. subtilis. The physiological-biochemical properties of these two groups of organisms showed that B. amyloliquefaciens differed from B. subtilis by their ability to grow in 10% NaCl, characteristic growth on potato plugs, i...
