abstract
Molecules exuded by plant roots are thought to act as signals to influence the ability of microbial strains to colonize the roots and to survive in the rhizosphere. Differential bacterial responses to signals from different plant species may mediate the selection of specific rhizosphere populations. Very little, however, is known about the effects of plant exudates on patterns of bacterial gene...
Agroinfiltration is used to treat plants with modified strains of Agrobacterium tumefaciens for the purpose transient in planta expression genes transferred from bacterium. These encode valuable recombinant proteins therapeutic or industrial applications. Treatment large quantities industrial-scale protein production exposes bacteria (harboring interest) agroinfiltration medium that devoid nutr...
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. Ralstonia solanacearum is an economically important plant pathogen with an unusually large host range. The Moko (banana) and NPB (not pathogenic to banana) strain groups are closely related but are adapted to distinct hosts. Previous comparative genomics studies uncovered very few differences that could account for the host range difference between these pathotypes. To better unders...
The rice blast fungus Magnaporthe oryzae is a model for studying fungal-plant interactions. Although it produces two types of spores (microconidia and macroconidia), previous infection studies have exclusively dealt with macroconidia. Germination of microconidia has not been reported, and their role in plant infection is not defined. Here we show that approximately 10% of microconidia germinate...
Plant has evolved along microbial symbionts, including bacteria, archaea, fungi, and protista. These symbionts, i.e. microorganisms living in close association with the host, with their collection of intricate genetic components have improved plant fitness by adding essential and functional capabilities. Therefore, one might continuously see plant as a superorganism composed of an amalgam of bo...
Sterols, a class of lipids found in the cellular membranes of all eukaryotes, have vital roles in regulating membrane fluidity and permeability. While animal cells contain cholesterol in their membranes, plant cells contain phytosterols such as campesterol, sitosterol, and stigmasterol. The sterol ergosterol, discovered more than a century ago from the ergot fungus Claviceps purpurea [1], is a ...
