Knowledge on the factors that determine the composition of bacterial communities in the vicinity of roots (rhizosphere) is essential to understand plant-soil interactions. Plant species identity, plant growth stage and soil properties have been indicated as major determinants of rhizosphere bacterial community composition. Here we show that the presence of saprotrophic fungi can be an additiona...
Prokaryote, viruses, and eukaryotes chromosomes contain fragments of DNA can move and migrate to other parts of the chromosome calling as Transposition and play an important role in new combinations of gene production. DNA fragments carrier the genes or transposons are the transposable elements that may called gene mutant also. Transposons can move to another position of the same chromosome or ...
Fusarium graminearum is the pathogenic agent of Fusarium head blight (FHB), which is a destructive disease on wheat and barley, thereby causing huge economic loss and health problems to human by contaminating foods. Identifying pathogenic genes can shed light on pathogenesis underlying the interaction between F. graminearum and its plant host. However, it is difficult to detect pathogenic genes...
Background and Objective: The endophytes are the fungi or bacteria that live within a plant in a symbiotic relationship. This study aimed to investigate the effect of isolated bacterial endophytes from Allium jesdianum on some bacterial pathogens such as Staphylococcus aureus, Escherichia coli as well as pathogenic fungi, including Trichophyton mentagrophytes and Candida albicans. Materials an...
1-Corydalmine,an alkaloid isolated from roots of Corydalis chaerophylla inhibited spore germination of some plant pathogenic as well as saprophytic fungi e.g. Alternaria brassicae, A. brassicicola, A. solani, Curvularia lunata, C. maculans, C. sp., C. pallscens, Erysiphe pisi, Fusarium udum, Helminthosporium species,H. penniseti and a Heterosporium species. 1-Corydalmine significantly inhibited...
Many plants have evolved adaptations in order to survive in low nitrogen environments. One of the best-known adaptations is that of plant symbiosis with nitrogen-fixing bacteria; this is the major route by which nitrogen is incorporated into plant biomass. A portion of this plant-associated nitrogen is then lost to insects through herbivory, and insects represent a nitrogen reservoir that is ge...
As in other eukaryotes, protein kinases play major regulatory roles in filamentous fungi. Although the genomes of many plant pathogenic fungi have been sequenced, systematic characterization of their kinomes has not been reported. The wheat scab fungus Fusarium graminearum has 116 protein kinases (PK) genes. Although twenty of them appeared to be essential, we generated deletion mutants for the...
Oomycetes comprise a diverse group of organisms that morphologically resemble fungi but belong to the stramenopile lineage within the supergroup of chromalveolates. Recent studies have shown that plant pathogenic oomycetes have expanded gene families that are possibly linked to their pathogenic lifestyle. We analyzed the protein domain organization of 67 eukaryotic species including four oomyce...
