Production of high yield short duration Brassica napus by interspecific hybridization between B. oleracea and B. rapa.

Brassica napus is a leading oilseed crop throughout many parts of the world. It is well adapted to long day photoperiods, however, it does not adapt well to short day subtropical regions. Short duration B.

Formation of macromolecule complex with Bacillus thuringiensis Cry1A toxins and chlorophyllide binding 252-kDa lipocalin-like protein locating on Bombyx mori midgut membrane.

P252, a 252-kDa Bombyx mori protein located on the larval midgut membrane, has been shown to bind strongly with Bacillus thuringiensis Cry1A toxins (Hossain et al. Appl Environ Microbiol 70:4604-4612, 2004). P252 was also shown to bind chlorophyllide (Chlide) to form red fluorescence-emitting complex Bm252RFP with significant antimicrobial activity (Pandian et al.

A novel 96-kDa aminopeptidase localized on epithelial cell membranes of Bombyx mori midgut, which binds to Cry1Ac toxin of Bacillus thuringiensis.

Proteins in the brush border membrane (BBM) of the midgut binding to the insecticidal Cry1Ac toxin from Bacillus thuringiensis were investigated to examine the lower sensitivity of Bombyx mori to Cry1Ac, and new aminopeptidase N that bound to Cry1Ac was discovered. DEAE chromatography of Triton X-100-soluble BBM proteins from the midgut revealed 96-kDa aminopeptidase that bound to Cry1Ac. The enzyme was purified to homogeneity and estimated to be a 96.

Characterization of a novel plasma membrane protein, expressed in the midgut epithelia of Bombyx mori, that binds to Cry1A toxins.

We describe the properties of a novel 252-kDa protein (P252) isolated from brush border membranes of Bombyx mori. P252 was found in a Triton X-100-soluble brush border membrane vesicle fraction, suggesting that it may be a component of the midgut epithelial cell membrane. P252 was purified to homogeneity, and the amino acid sequence of two internal peptides was determined, but neither of the peptides matched protein sequences in the available databases.
