A microbial technique of biocontrol using the interaction of microorganisms to repress the growth of deleterious bacteria and viruses was deveioped. The bacterial strain used in this work also improved the growth of fishes and crustaceans. To control the bacterial population, protozoa was found having a significant role in the aquaculture biotope, The concept of biocontrol in aquaculture is als...

The translation initiation factors (IFs) IF1/eIF1A and IF2e/IF5B have been conserved throughout all kingdoms. Although the central roles of the bacterial factors IF1 and IF2 were established long ago, the importance of their eukaryotic homologs, eukaryotic IFs (eIFs) eIF1A and eIF5B, has only recently become evident. The translation machinery in eukaryotes is more complex and accordingly, eIF1A...

Insertion sequences (ISs) are small transposable elements widespread in bacterial genomes, where they play an essential role in chromosome evolution by stimulating recombination and genetic flow. Despite their ubiquity, it is unclear how ISs interact with the host. Here, we report a survey of the orientation patterns of ISs in bacterial chromosomes with the objective of gaining insight into the...

common bacterial blight (cbb) caused by xanthomonas axonopodis pv. phaseoli is a serious disease of bean fields in iran and the world. chemical control of cbb is inefficient, therefore the use of resistant genotypes with stability production is the most suitable alternative. stability and adaptability of 26 bean genotypes yield in the presence and absence of cbb were evaluated in agricultural r...

Studying how antimicrobial peptides interact with bacterial cells is pivotal to understand their mechanism of action. In this paper we explored the use of Circular Dichroism to detect the secondary structure of two antimicrobial peptides, magainin 2 and cecropin A, with E. coli bacterial cells. The results of our studies allow us to gain two important information in the context of antimicrobial...

InlB, a surface protein of the human bacterial pathogen Listeria monocytogenes, interacts with the receptor tyrosine kinase Met on host cells to enable bacterial invasion. In this issue, Niemann et al. (2007) provide the first structural evidence that InlB does not compete for the same interaction site on Met as the natural ligand HGF.

Two-hybrid screening is a standard methodology to identify and characterize protein-protein interactions that has become an integral component of many proteomic investigations. The twohybrid system was initially developed using yeast as a host organism. However, bacterial two-hybrid systems have also become common laboratory tools and are preferred in some circumstances, although yeast and bact...

Bacterial cells and other biological particles carry charged macromolecules on their surface that form a "soft" ion-permeable layer. In this paper, we test the applicability of an electrokinetic theory for soft particles to characterize the electrophoretic mobility (EPM) and adhesion kinetics of bacterial cells. The theory allows the calculation of two parameters--the electrophoretic softness a...

Since its initial description, the yeast two-hybrid (Y2H) system has been widely used for the detection and analysis of protein-protein interactions. Mating-based strategies have been developed permitting its application for automated proteomic interaction mapping projects using both exhaustive and high-throughput strategies. More recently, a number of prokaryotic two-hybrid (P2H) systems have ...

the interaction between root-colonizing pseudomonas fluorescens strain cha0mcherry and three wheat cultivars (bolani, roushan, forno) was studied as a phenomenon to be employed in the control of wheat leaf rust disease (puccinia triticina). cha0mcherry was inoculated using seed treatment method. the application of cha0mcherry reduced the number of pustules on leaves via inducing systemic resist...
