Escherichia coli O157:H7 has been associated with contaminated seed sprout outbreaks. The majority of these outbreaks have been traced to sprout seeds contaminated with low levels of pathogens. Sanitizing sprout seeds presents a unique challenge in the arena of produce safety in that even a low residual pathogen population remaining on contaminated seed(More)
The European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), is an economically important insect pest of corn, Zea mays L., in the United States and Canada. The development of genetically modified corn expressing genes derived from Bacillus thuringiensis (Bt) that encodes insecticidal crystalline (Cry) proteins has proven to be effective(More)
The origin of polystichy in the maize ear and central tassel spike continues to challenge our understanding of evolution in this important crop species. In this paper we tested the hypothesis that the change in phyllotaxy occurs in the region of husk leaf production before the transition to reproductive growth. Young ear or presumptive ear primordia were(More)
The developmental anatomy of the regeneration of adventitious shoot apices from leaves of Vaccinium corymbosum L. ‘Aurora’ is described for the first time. Leaves were cultured for 0, 3, 6, 10, 15, or 21 d with their upper or lower surface in contact with Woody Plant Medium supplemented with 2% sucrose, vitamins, 5 μM thidiazuron, and 0.5% Agargel. Initial(More)
Short term photoheterotrophic growth of Lemna minor in the presence of 100 micrograms per milliliter (440 micromolar) cytidine deoxyriboside bleaches the fronds in the absence of effect upon growth rate (Frick 1978 Plant Physiol 61: 989-992). Serial sections of mesophyll cells of green and bleached fronds were compared in the light microscope. The number of(More)
