Absence of genome-wide changes in DNA methylation during development of the zebrafish
(Nature Publishing, 1999-10)
MBD2 is a transcriptional repressor belonging to the MeCP1 histone deacetylase complex
(Nature Publishing Group, 1999-09)
Mammalian DNA is methylated at many CpG dinucleotides. The biological consequences of methylation are mediated by a family of methyl-CpG binding proteins (1–4). The best characterized family member is MeCP2, a transcriptional ...
Direct observation of DNA translocation and cleavage by the EcoKI endonuclease using atomic force microscopy
(Nature Publishing, 1999-01)
Vestiges of a DNA methylation system in Drosophila melanogaster?
(Nature Publishing Group, 1999-11)
The two types of 3-dehydroquinase have distinct structures but catalyze the same overall reaction
(Nature Publishing Group, 1999-07)
The structures of enzymes catalyzing the reactions in central metabolic pathways are generally well conserved as are their catalytic mechanisms. The two types of 3-dehydroquinate dehydratase (DHQase) are therefore most ...
Alternative mating tactics and extreme male dimorphism in fig wasps.
(The Royal Scoiety, 1997)
The dimorphisms in morphology and behaviour of male fig wasps are among the most extreme in the animal kingdom, and offer excellent oppotunities to test the predictions of certain sexual selection models.
Conflict of interest in a mutualism: documenting the elusive fig wasp seed trade-off
(The Royal Society, 1997)
The generally accepted view that mutualisms represent reciprocal exploitations implies a greater or lesser degree of inherent tension between the partners. This view emphasizes the importance of identifying conflicts of ...
The ecology of the New World fig-parasitising wasps Idarnes and implications for the evolution of the fig-pollinator mutualism.
(The Royal Society, 1994)
Figs and their pollinating wasps are perhaps the classic example of an obligate mutualism. In addition, figs have a suite of non-pollinating parasitic wasps whose basic ecolgy is largely undescribed. Figs therefore present ...
Modelling ecological interaction despite object-oriented modularity
Ecological modellers may be deterred from using object-oriented programming languages by reports of the inherent rigidity of the object-oriented formulation, giving rise to a poor representation of biotic interaction. ...
Learning in Helicoverpa armigera (Lepidoptera: Noctuidae): a new look at the behaviour and control of a polyphagous pest
(CAB International, 1999)
Recent experimental evidence has shown that learning occurs in the host selection behaviour of Helicoverpa armigera (Hübner), one of the world‘s most important agricultural pests. This paper discusses how the occurrence ...
