N,N-dimethyl-p-toluidine was nominated for toxicology and carcinogenesis studies by the National Cancer Institute based on the potential for human exposure through its use in dental materials and bone cements and the lack of toxicity and carcinogenicity data. Male and female F344/N rats and B6C3F1/N
Granular bodies in root primary meristem cells of Zea mays L. var. Cuscoensis K. (Poaceae) that enter young vacuoles by invagination: a novel ribophagy mechanism.

Because it has a very large, very rapidly growing primary root, we evaluated giant maize (Zea mays var. Cuscoensis) as a model organism for root research. Granular inclusions are a common feature of cells in many organisms, but they are not common in root meristems. We here report the presence of

N,N-Dimethyl-p-toluidine (DMPT) is used as a polymerization accelerator, in industrial glues, and as an intermediate in dye and pesticide synthesis. There is potential for human exposure to DMPT. The disposition of oral and intravenous (i.v.) doses of [14C]DMPT in F344 rats and B6C3F1 mice was

Several modifications of a wild-type green fluorescent protein (GFP) gene were combined into a single construct, driven by the ubi-1 promoter and intron region, and transformed into maize. Green fluorescence, indicative of GFP expression, was observed in stably transformed callus as well as in

Twenty juvenile New Zealand white rabbits were dosed orally once daily with 1,000 mg of nalidixic acid/kg for 3, 7, and 14 consecutive days, then for 14 days followed by a 14-day recovery period. Eighteen age-matched rabbits were allotted to four groups and given corn oil vehicle to serve as

We developed a novel sectioning and staining method to make high contrast, high resolution sections of plant tissue for light microscopy. Specimens of teosinte (Zea mays L., ssp. mexicana) root tips were fixed and embedded in Technovit 7100™ plastic resin. Thin sections, 1-2.5 μm, were

Roots and shoots of corn seedlings (Zea mays L. var. Dixie 18) germinated in trifluralin (alpha,alpha,alpha-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) solutions are characterized by radial enlargement of the cortical cells and by multinucleate cells in the meristematic regions. Trifluralin
