Photosynthesis
The following picture is meant to symbolize the process of photosynthesis… Continue reading
Root parasitizing nematodes
I have been working on root knot nematodes for a while, and here are some images featuring this interaction. Continue reading
The Golden Angle
I became interested in the golden angle, because I was impressed by Aeonium plants I saw in Madeira and I wanted to model these plants. Continue reading

Ectomycorrhiza/ericoid mycorrhiza
Ectomycorrhiza and ericoid mycorrhiza are further forms of interactions of plant roots and fungi, which have evolved independently and at a later time points compared to arbuscular mycorrhiza. There are still more types of such interactions, but these three forms … Continue reading

Visualizing chromosomes
Chromosomes are large DNA-molecules containing the information for huge numbers of genes. Although we are dealing with a completely different scale, when compared to the visualization of genes, we are having exactly the same problem: A linear sequence of huge amounts of data. Continue reading
Visualizing genes
DNA is the biological way of storing information, the equivalent to a computer’s main disk. This post will try to focus on this side of DNA and how it can be visualized. Continue reading
Fractals
Fractals are repetitive, self-similar structures, often observed in nature… Continue reading
Arbuscular mycorrhiza
Arbuscular mycorrhiza is a very ancient interaction dating back to the time, when the very first land plants colonized the main land… Continue reading

DNA – beyond the double helix (II)
Packaging of DNA-molecules (within cells or cell nuclei) is a very interesting topic, first because packaging determines, how fast the information stored in the DNA can be used by the cell, and second, because cellular compartments appear to be tiny compared to DNA-molecules. Continue reading
