serine protease inhibitors enhanced the insecticidal activity of the
insect control proteins from Bacillus thuringiensis var.
kurstaki, var. tenebrionis, and var. israelensis against their target insects, tobacco budworm and
other lepidopterans, Colorado potato beetle, and mosquito, respectively.
B. thuringiensis protein
concentrations, at levels causing minimal insect mortality (10-20%), were mixed with purified
protease inhibitors and assayed against the appropriate target insects.
The presence of extremely low levels
(4 FM) of protease inhibitors enhanced the insecticidal activity of B. thuringiensis var. kurstaki by
2-20-fold. Protease inhibitors also potentiated the insect growth
inhibitory
activity of sublethal B. thuringiensis var. kurstaki protein
concentrations. Genetically improved tobacco plants expressing a
protease inhibitor fused to a truncated B. thuringiensis insect control protein showed levels of
activity enhancement similar to those seen with purified protease
inhibitors. http://pubs.acs.org/cgi-bin/abstract.cgi/jafcau/1990/38/i04/f-pdf/f_jf00094a051.pdf?sessid=6006l3

The
structure of an insect control protein gene from Bacillus
thuringiensis var. kurstaki
HD−1 was determined, and truncated forms of the gene that
express a
functional insecticidal protein were generated. Two of these truncated
genes were incorporated into a plant expression vector for Agrobacterium−mediated
transformation. Transgenic tomato plants containing the chimeric genes
express the insect control protein gene. Such expression confers
tolerance to lepidopteran larvae on the transgenic tomato plants and
their progeny. These engineered tomato plants represent a significant
step to increased selectivity, specificity and efficiency in insect
control.

tomato plants expressing a lepidopteran-specific insect control protein
from Bacillus thuringiensis var. kurstaki
HD-1 (B.t.k.)
were field tested in 1987 and 1988 to evaluate their efficacy under
normal field conditions. When infested with eggs of the tobacco
hornworm (Manduca sexta), the transgenic plants
showed only
very limited feeding damage on the leaves near the inoculated sites
soon after the larvae hatched, and sustained no further damage. In
contrast, nontransgenic control plants suffered heavy feeding damage
and were almost completely defoliated within two weeks. Significant
control of tomato fruitworm (Heliothis zea) and
tomato pinworm (Keiferia lycopersicella) was also
observed. These results demonstrate that transgenic tomato plants
containing a gene encoding a B.t.k. protein can
provide control of lepidopteran insect pests under field conditions.

The gene encoding the
coleopteran−specific insect control protein from Bacillus
thuringiensis var. tenebrionis was
isolated and characterized. When expressed in either E. coli
or P. fluorescens
the gene directs the production of biologically active insect control
protein that is lethal to Colorado potato beetle. The gene contains two
functional translational initiation codons in the same reading frame
leading to the production of both the full length protein and an
N−terminal truncated form. The gene has been engineered to
produce each
of these two proteins separately, and each is active against Colorado
potato beetle. Native crystals from B.t. var. tenebrionis
were found to contain five distinct proteins derived from this single
gene either as primary translation products or the result of
proteolysis. Comparison of this gene to a
lepidopteran−specific B.t. gene revealed
only limited regions of homology.
