Bt corn has been genetically modified to express the Cry1Ab protein of Bacillus thuringiensis to kill lepidopteran pests. Fluorescence microscopy and staining with toluidine blue indicated a higher content of lignin in the vascular bundle sheaths and in the sclerenchyma cells surrounding the vascular bundle in all ten Bt corn hybrids, representing three different transformation events, studied than of their respective non-Bt isolines. Chemical analysis confirmed that the lignin content of all…

Influence of Bt transgenes on cell wall lignification and digestibility of maize stover for silage
Comparisons of non-Bt/Bt hybrid pairs, for both whole plants and internodes, found no consistent differences in yield, nutrient content, in vitro ruminal NDF digestibility, or lignin concentration.
Crop residue composition and decomposition in transgenic corn agroecosystems: effects of the Bacillus thuringiensis gene and herbivory
Bt (Bacillus thuringiensis) corn (Zea mays L.) is reported to have a higher lignin concentration and be more resistant to degradation compared to conventional non-Bt (NBt) hybrids. NBt hybrids are
Field‐Grown Bt and non‐Bt Corn: Yield, Chemical Composition, and Decomposability
It is concluded that the Bt gene does not affect the agronomic performance or the chemical composition of corn in fields without herbivory, and that Bt corn residue may be more susceptible to decomposition than non-BtCorn residue.
Decomposition of Bt and Non-Bt Corn Hybrid Residues in the Field
Results of a previous laboratory study indicated that six transgenic crops expressing the Cry1Ab insecticidal protein from Bacillus thuringiensis (Bt) decomposed at a slower rate than their
European corn borer injury effects on lignin, carbon and nitrogen in corn tissues
ECB injury and the Bt gene had subtle effects on the chemical composition of corn tissue, which did not alter the short-term decomposition of corn residues.
Transgenic Bt plants decompose less in soil than non-Bt plants
Bt plants are plants that have been genetically modified to express the insecticidal proteins (e.g. Cry1Ab, Cry1Ac, Cry3A) from subspecies of the bacterium, Bacillus thuringiensis (Bt), to kill
Crop residue chemistry, decomposition rates, and CO2 evolution in Bt and non-Bt corn agroecosystems in North America: a review
Corn (Zea mays L.) is a major cereal crop, with production on more than one-fifth of the agricultural land worldwide. In North America, about 50% of corn acreage is planted with transgenic corn


Relationship between Plant Composition and European Corn Borer Resistance in Three Maize Populations
In general, there was an association between plant cell wall composition and ECB resistance, but genetic background influenced the relationship.
Repression of lignin biosynthesis promotes cellulose accumulation and growth in transgenic trees
It is indicated that lignin and cellulose deposition could be regulated in a compensatory fashion, which may contribute to metabolic flexibility and a growth advantage to sustain the long-term structural integrity of woody perennials.
Manipulation of lignin quality by downregulation of cinnamyl alcohol dehydrogenase
The improved chemical extractability of lignin in CAD antisense plants supports a role for this technology in improving the pulp and paper-making value of forest trees while the similarity with brown-midrib mutants suggests a route to more digestible forage crops.
Using the acetyl bromide assay to determine lignin concentrations in herbaceous plants: some cautionary notes.
Characterization of the reaction conditions revealed that the acetyl bromide reagent readily degrades xylans, a prominent polysaccharide group within all lignified plants, which results in increased absorbance in the 270-280 nm region that is used to quantify lignin.
Effect of degradation on the porosity and surface area of forage cell walls of differing lignin content
Cell walls, prepared from the stems of wheat, maize, lucerne and rape and from timothy grass, were degraded using a commercial cellulase enzyme preparation. Timothy and lucerne were extensively
Characteristics of plant cell walls affecting intake and digestibility of forages by ruminants.
A simple model of cell-wall digestion and passage in which ruminal fill is a function of rates of digestion and Passage, as well as the indigestible fraction of thecell-wall indicates that cell- wall concentration and rate of passage are the most critical parameters determining ruminalFill.
Persistence and Biological Activity in Soil of Insecticidal Proteins from Bacillus thuringiensis and of Bacterial DNA Bound on Clays and Humic Acids
Because of the large differences in the chemical composition and structure between these proteins and DNA, as well as between clays and humic acids, these studies can serve as models for the potential fate and effects of other biomolecules that will be introduced to soil from “factories” of transgenic plants and animals genetically engineered to produce vaccines, hormones, antibodies, toxins, pharmaceuticals, and other bioactive compounds.
Brown-midrib genes of maize: a review
L'utilisation des fourrages par les ruminants depend essentiellement de la teneur en constituants parietaux, principalement cellulose et hemicelluloses, et de leur digestibilite, reduite
