Coffee (Coffea arabica cv. Rubi) seed germination: mechanisms and regulation
Coffee seeds display slow and variable germination which severely hampers the production of seedlings for planting in the following growth season. Little work has been done with the aim to understand the behavior of coffee seeds during germination and there is a lack of information concerning the regulation of the germination process. This thesis ...

The role of auxin in cell specification during arabidopsis embryogenesis
Auxin is a structurally simple molecule, yet it elicits many different responses in plants. In Chapter 1 we have reviewed how specificity in the output of auxin signaling could be generated by distinct regulation and the unique properties of the members of the Aux/IAA and ARF transcription factor families. In Chapter 2 we further investigated the g...
Identification of novel MONOPTEROS target genes in embryonic root initiation

The biochemical basis of plant development
Plants develop highly elaborate structures, ranging from small mosses to large trees. All these structures are made by stem cells and consist of a few basic types of tissue. The field of Biochemistry of Plant Development studies the mechanisms by which regulatory proteins control the formation of stem cells and tissues. The young embryo, developing...
Microspore embryogenesis: reprogramming cell fate from pollen to embryo development
Microspore embryogenesis is an expression of plant cell totipotency that leads to the production of haploid embryos. Besides being a widely exploited plant breeding tool, microspore embryogenesis is also a fascinating system that can be used to obtain a deeper mechanistic understanding of plant totipotency. This thesis aims to provide more insight ...
Structural basis for specific gene regulation by Auxin Response Factors
Auxin is a plant hormone that triggers a broad variety of responses during plant development. These responses range from correct cell division patterns during embryogenesis to formation and growth of different organs. Due to its importance for plant growth and development, many aspects of the biology of auxin have been studied. In Chapter 2, we use...
