Methylation of somatic and sperm DNA in the homosporous fern Ceratopteris richardii
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-12)
Plants, in general, have a high proportion of their CpG and CpNpG nucleotide motifs modified with 5-methylcytosine (5mC). Developmental changes in the proportion of 5mC are evident in mammals, particularly during gametogenesis ...
Populus tremuloides photosynthesis and crown architecture in response to elevated CO 2 and soil N availability
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-04)
We tested the hypothesis that elevated CO 2 would stimulate proportionally higher photosynthesis in the lower crown of Populus trees due to less N retranslocation, compared to tree crowns in ambient CO 2 . Such a response ...
Kinetics of toluene degradation by toluene-oxidizing bacteria as a function of oxygen concentration, and the effect of nitrate
(Blackwell Publishing Ltd, 1997-05)
The kinetics of toluene degradation as a function of oxygen concentration were compared for six strains of toluene-oxidizing bacteria using initial rate assays. The effect of nitrate was also examined. Rates of degradation ...
Coming to terms with heritability
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-03)
The complex mechanisms of heredity are little appreciated by non-specialists, in some measure, because of misunderstandings that are perpetuated when words used for technical terms have other, more widely understood, folk ...
Olfactory versus visual cues in a floral mimicry system
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-02)
We used arrays of artificial flowers with and without fragrance to determine the importance of olfactory and visual cues in attracting insects to a floral mimic. The mimic is a fungus, Puccinia monoica Arth., which causes ...
zrp2: a novel maize gene whose mRNA accumulates in the root cortex and mature stems
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-10)
A near full-length cDNA clone (pZRP2) was isolated from a cDNA library constructed from maize root mRNAs. The predicted polypeptide has a calculated molecular mass of 66 975 Da, is largely hydrophilic, and contains 26 ...
Cloning of the human NADH: ubiquinone oxidoreductase subunit B13: localization to Chromosome 7q32 and identification of a pseudogene on 11p15
(Springer-Verlag; Springer-Verlag New York Inc., 1997-01)
Cloning, chromosomal mapping, and expression of the human eHAND gene
(Springer-Verlag; Springer-Verlag New York Inc., 1997-11)
Meeting report: 10th International Mouse Genome Conference
(Springer-Verlag; Springer-Verlag New York Inc., 1997-07)
