Glyphosate: a once-in-a-century herbicide.
The use of this virtually ideal herbicide is now being threatened by the evolution of glyphosate-resistant weeds, and adoption of resistance management practices will be required to maintain the benefits of glyphosate technologies for future generations. Expand
Role of peroxidase in the development of water-impermeable seed coats in Sida spinosa L.
The results support the view that peroxidase is involved in the polymerization of soluble phenolics to insoluble lignin polymers during development of prickly sida seed coats, causing the formation of a water-impermeable barrier prior to seed dehydration. Expand
Natural products in crop protection.
The historical use of natural products in agricultural practices, the impact ofnatural products on the development of new pesticides, and the future prospects for natural products-based pest management are reviewed. Expand
The current status and environmental impacts of glyphosate-resistant crops: a review.
Glyphosate-resistant crops have promoted the adoption of reduced- or no-tillage agriculture in the USA and Argentina, providing a substantial environmental benefit and the development and use of failsafe introgression barriers in crops with such linked genes is needed. Expand
Localization of Artemisinin and Artemisitene in Foliar Tissues of Glanded and Glandless Biotypes of Artemisia annua L.
The tissue localization of the antimalarial sesquiterpenoid compound artemisinin in annual wormwood (Artemisia annua L.) was determined by differential extraction of a glanded biotype and through the use of a glandsless biotype, indicating that artemisine and artemisitene present in foliar tissue are localized entirely in the subcuticular space of capitate glands of A. annua.

Glyphosate Effects on Plant Mineral Nutrition, Crop Rhizosphere Microbiota, and Plant Disease in Glyphosate-Resistant Crops
Most of the available data support the view that neither the GR transgenes nor glyphosate use in GR crops increases crop disease and yield data on GR crops do not support the hypotheses that there are substantive mineral nutrition or disease problems that are specific to GR crops. Expand
Aminomethylphosphonic acid, a metabolite of glyphosate, causes injury in glyphosate-treated, glyphosate-resistant soybean.
Results suggest that soybean injury to GR soybean from glyphosate is due to AMPA formed from glyphosate degradation, a known phytotoxin. Expand

The high level of adoption of glyphosate-resistant crops by North American farmers has helped to significantly reduce the value of the remaining herbicide market, which has resulted in reduced investment in herbicide discovery, which may be problematic for addressing future weed-management problems.

Detoxification and Transcriptome Response in Arabidopsis Seedlings Exposed to the Allelochemical Benzoxazolin-2(3H)-one*
The capacity of Arabidopsis to detoxify exogenously supplied BOA was analyzed by quantification of the major known metabolites, revealing that detoxification occurs predominantly through O-glucosylation of the intermediate BOA-6-OH, most likely requiring the sequential action of as-yet-unidentified cytochrome P450 and UDP-glUCosyltransferase activities.
