From the beginning of life 4 billion years ago, the emergence of eukaryotes, some of which soon joined forces with a photosynthesising cyanobacteria, paving the way for an almost unbelievable variety of algae, from which streptophytic algae found their way onto land more than 500 million years ago and gradually evolved land plants until we are where we are today.

Endosymbiosis acts as a shaping force in evolution. Endosymbionts that evolved billions of years ago are shaping the face of the earth today, and they are constantly taking on new, fascinating tasks. Fifty years ago, endosymbiosis was met with scepticism, but today it is recognised as a phenomenon responsible for some of the greatest changes in life.

Schreiber et al. 2021, Evolution and Domestication of rye. The Rye Genome.

Where does our rye come from? What makes it special? This chapter gives an insight into the evolution and cultural history of this cereal, which is nevertheless important in parts of the world.

Melon and watermelon belong to distinct species and followed different routes during their domestication. Therefore, it is not surprising that they became sweet on different ways as well and different genes are responsible for the loss of bitterness.

Genebanks hold a great potential to maintain and study the diversity of crops. In this article the current state and the prospects of molecular passport data as a universal monitoring tool within and between genebanks is reviewed

Pan-genomes are going another step forward to examine the diversity of crop plants in greater detail. Therefore multiple individuals are sequenced very deep to take a close look into different levels of variation. This article describes how genebanks can contribute to such an approach and how the pan-genome for barley will be set up.

A review wich is dealing with the modifications of wheat and barley in the course of domestication and cultivation, to shed light into the genetic basics of these two important cereal crops.

crop plant diversity

This review, a summary of the current state of research, is dealing with the most recent developments in sequencing- and analyses techniques and their importance for studying the cultural history of economically less important crops. With the help of these methods that become increasingly cost-effective we gain a better understanding of the individual domestication histories, examine the present diversity in greater detail and unravel the diversification of our crop plants.

Of course in this list of scientific graphics and illustrations my PhD thesis may not be missing. An entire page on this homepage is dedicated to its art and content.
