We have isolated a constitutive promoter sequence, tCUP, from tobacco by T-DNA tagging using a promoterless GUS-nos3' reporter gene construct. The T-DNA integration event produced a translational fusion with the GUS gene that is expressed widely in organs, at both the mRNA and enzyme activity levels. In tobacco transformed with a tCUP-GUS-nos3' gene, GUS(More)
A doubled haploid barley (Hordeum vulgare L.) population that was created from a cross between cultivars 'Léger' and 'CI 9831' was characterized by RAPD (random amplified polymorphic DNA) markers for resistance to isolate WRS857 of Pyrenophora teres Drechs. f. sp. maculata Smedeg., the causal agent of the spot form of net blotch. Resistance, which initially(More)
The Oxoid Signal blood culture system (Oxoid USA, Inc., Columbia, Md.) was compared with the Roche Septi-Chek system (Roche Diagnostics, Div. Hoffmann-La Roche Inc., Nutley, N.J.), with the latter consisting of a tryptic soy broth (R-TSB) bottle with an attached agar slide unit and a Columbia broth bottle. A total of 5,034 cultures with equal volumes of(More)
The necessity to prevent and manage pain in reptiles is becoming increasingly important, as their use in scientific research and popularity as exotic pets continues to rise. It was hypothesized that feeding behavior would provide an adequate indicator of pain perception in the ball python (Python regius). Normal feeding was defined the previous week, where(More)
OBJECTIVES To quantify the effect of subcutaneous (SC) capsaicin injection on heart rate (HR) in ball pythons (Python regius) and to assess the efficacy of two opioids (morphine and butorphanol) in modifying this response. STUDY DESIGN Prospective, randomized, unmatched study. ANIMALS Eleven mixed-sex, captive-bred ball pythons. METHODS Snakes were(More)
