ISOLATION OF BACILLUS SPHAERICUS WITH IMPROVED EFFICACY AGAINST CULEX QUINQUEFASCIATUS (2007)

HYUN-WOO PARK, CLARE M. MANGUM, HE ZHONG, SABRINA R. HAYES

A Bacillus sphaericus highly toxic to 4th-stage Culex quinquefasciatus was isolated from sediment samples collected at Winter Beach marsh in Indian River County, Florida. This isolate, named WBM...

Synthesis of Additional Endotoxins in Bacillus thuringiensis subsp. morrisoni PG-14 and Bacillus thuringiensis subsp. jegathesan Significantly Improves Their Mosquitocidal Efficacy (2005)

Hyun-woo Park, Dennis K. Bideshi, Brian A. Federici

A fundamental principal of resistance management is that the more complex and potent a toxin mixture, the slower resistance will develop to the mixture in an insect population. Thus, to develop more...

Molecular Genetic Manipulation of Truncated Cry1C Protein Synthesis in Bacillus thuringiensis To Improve Stability and Yield

Park, Hyun-Woo, Bideshi, Dennis K., Federici, Brian A.

Cry1 protoxins of Bacillus thuringiensis are insecticidal 135-kDa proteins synthesized and assembled into parasporal crystals during sporulation. After ingestion, these crystals dissolve in the...

Optimization of Cry3A Yields in Bacillus thuringiensis by Use of Sporulation-Dependent Promoters in Combination with the STAB-SD mRNA Sequence

Park, Hyun-Woo, Ge, Baoxue, Bauer, Leah S., Federici, Brian A.

The insecticidal activity of Bacillus thuringiensis strains toxic to coleopterous insects is due to Cry3 proteins assembled into small rectangular crystals. Toxin synthesis in these strains is...

Recombinant Strain of Bacillus thuringiensis Producing Cyt1A, Cry11B, and the Bacillus sphaericus Binary Toxin

Park, Hyun-Woo, Bideshi, Dennis K., Federici, Brian A.

A novel recombinant Bacillus thuringiensis subsp. israelensis strain that produces the B. sphaericus binary toxin, Cyt1Aa, and Cry11Ba is described. The toxicity of this strain (50% lethal...

Cyt1A of Bacillus thuringiensis Delays Evolution of Resistance to Cry11A in the Mosquito Culex quinquefasciatus

Wirth, Margaret C., Park, Hyun-Woo, Walton, William E., Federici, Brian A.

Insecticides based on Bacillus thuringiensis subsp. israelensis have been used for mosquito and blackfly control for more than 20 years, yet no resistance to this bacterium has been reported....

Minireplicon from pBtoxis of Bacillus thuringiensis subsp. israelensisâ–ż

Tang, Mujin, Bideshi, Dennis K., Park, Hyun-Woo, Federici, Brian A.

A 2.2-kb fragment containing a replicon from pBtoxis, the large plasmid that encodes the insecticidal endotoxins of Bacillus thuringiensis subsp. israelensis, was identified, cloned, and sequenced....

Iteron-Binding ORF157 and FtsZ-Like ORF156 Proteins Encoded by pBtoxis Play a Role in Its Replication in Bacillus thuringiensis subsp. israelensisâ–ż

Tang, Mujin, Bideshi, Dennis K., Park, Hyun-Woo, Federici, Brian A.

We recently identified a minireplicon of pBtoxis from Bacillus thuringiensis subsp. israelensis that contained an operon encoding two novel proteins (ORF156 and ORF157), both of which are required...
