The bananas have a gene from green pepper to protect against banana Xanthomonas wilt (BXW which costs farmers in Africa's Great lakes region an estimated half a billion dollars every year.

and found a new bacterium Burkholderia australis that promotes plant growth through a process called nitrogen fixation.

While two of the most abundant bacteria did not have noticeable effects on plant growth Burkholderia australis was doing quite well in competition with other soil bacteria in the environment

We found that bacteria from the Pseudomonas family in particular Pseudomonas extremorientalis are salt-resistant and grow close to the roots where they compete with other bacteria for colonization.

Here Pseudomonas produce antibiotics that plants use to defend themselves against fungi trigger the rooting process

To better exploit these useful bacterial strains the Uzbek microbiologist has come up with a technique that allows the selective enrichment of Pseudomonas strains.

and his team managed to remove the ability of the Pseudomonas aeruginosa microorganism to resist the antibiotic medication tetracycline by limiting its access to food and oxygen.

(E coli) as well as species of Klebsiella Enterobacter Pseudomonas and Serratia. Late-onset sepsis commonly occurs in about 22 percent of very-low-birth-weight babies the United states

These lactic acid bacteria have now been tested on severe human wound pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) Pseudomonas aeruginosa and vancomycin-resistant Enterococcus (VRE) among others.

Through genetic testing scientists identified the disorder as being caused by the bacterium Xanthomonas axonopodis. The disease is most likely spread by wind-driven rain

whether the bacteria Ralstonia eutropha maintains its ability to produce polyhydroxyalkanoates (PHA) in microgravity. A biodegradable polyester created by bacterial fermentation PHA can be used to make things such as skin grafts and valve replacements

and soil sciences in UD's College of Agriculture and Natural resources has identified a naturally occurring microbe living right in the soil around rice plants--Pseudomonas chlororaphis EA105--that inhibits the devastating fungus known as rice blast.

and colleagues Spence Donofrio and Vidhyavathi Raman showed that Pseudomonas chlororaphis EA105 strongly inhibited the formation of the appressorium and that priming rice plants with EA105 prior to infection by rice blast decreased lesion

These bacteria were tested then in the laboratory with Pseudomonas chlororaphis EA105 demonstrating the strongest impact on rice blast.

Bais points out that although hydrogen cyanide is produced commonly by pseudomonad bacteria the antifungal impact of Pseudomonas chlororaphis EA105 appears to be independent of cyanide production.

This summer he and his colleagues will conduct field trials using Pseudomonas chlororaphis EA105 on rice plants grown on the UD farm.

The work focused on bacteria known as Pseudomonas syringae pv. tomato DC3000 which can ruin tomatoes as well as Arabidopsis.

which is resistant to infection by Pseudomonas syringae. The Missouri and PNNL groups compared levels of metabolites in Arabidopsis to those in the mutant mkp1 form of the plant.

The same molecular machinery employed by Pseudomonas syringae is used also by a host of microbes to cause diseases that afflict people including salmonella the plague respiratory disease and chlamydia.

In our antibacterial studies we have been testing honey's activity against E coli Staphylococcus aureus and Pseudomonas aeruginosa among others.*

and parasitic ants and tested the effect of the extracts on the growth of bacterial pathogens in the lab. Plant pathogen Pseudomonas syringae was sensitive to the application of leg extracts of both ant species

In lab tests bacterial strains of the genera Bacillus Lactococcus Pantoea and Burkholderia effectively inhibited the growth of Pseudomonas bacteria isolated from infected acacia leaves.

The bacterial genus Burkholderia for example includes dangerous disease-causing pathogens--one species has even been listed as a potential bioterrorist agent

We have shown that a certain group of Burkholderia which have just been discovered in the last 12 years as plant-growth promoting bacteria are said not pathogenic the study's senior author Ann Hirsch a professor of molecular cell and developmental biology in the UCLA College of Letters and Science.

The findings of Hirsch and her colleagues indicate that several recently discovered Burkholderia species including Burkholderia tuberum could be used--cautiously--in nitrogen fixing.

These species the scientists discovered lack those genes that make other Burkholderia species harmful agents of infection.

We're especially interested in these recently described Burkholderia species because they are found primarily in the dry and acidic soils of the Southern hemisphere making them potentially important for agriculture in less productive areas.

For their study the UCLA life scientists performed a bioinformatics analysis of four symbiotic Burkholderia species all of

Unlike their dangerous cousins the four symbiotic Burkholderia species did not have associated genes with the virulence systems found in the pathogenic species. Burkholderia were discovered first as plant pathogens in 1949 by Walter Burkholder who identified them as the agent causing

Later Burkholderia species were identified as the causative agent of the disease melioidosis a public health threat especially in tropical countries like Thailand and in parts of Australia.

Although some members of the Burkholderia cepacia complex have been used to protect plants from dangerous fungal infections their potential to cause infection has resulted in severe limits on their use in agriculture.

It wasn't until many decades after Burkholder's discovery that closely related Burkholderia species were found to enter plant roots not as pathogens

Although the nodulating symbiotic species of Burkholderia are related to the more dangerous species a detailed analysis of their evolutionary relationships published earlier this year by Hirsch

The harmful Burkholderia species are more resistant to antibiotics than the symbiotic and agricultural strains.

In addition to the bioinformatics analysis in the current study the team analyzed resistance to a panel of common antibiotics and tested the potential of different Burkholderia species to cause infection in laboratory conditions.
