Seit 2015 führt die Universität Duisburg-Essen die Praxissemester-Begleitung in Blended-Learning-Formaten innerhalb eines Blocktagmodells durch. Studierende können so individuell, zeitlich und räumlich flexibel betreut werden. Einen festen Bestan

In higher plants, the plastome-encoded photosystem I-subunit PsaI is specifically required for photosystem I stability during high-light and chilling stress and leaf senescence.
PsaI is the only subunit of PSI whose precise physiological functio

The genomes of DNA-containing cell organelles (mitochondria, chloroplasts) can be laterally transmitted between organisms, a process known as organelle capture. Organelle capture often occurs in the absence of detectable nuclear introgression, and th

Summary Transgene expression from the plastid (chloroplast) genome provides unique advantages, including high levels of foreign protein accumulation, convenient transgene stacking in operons, and increased biosafety due to exclusion of plastids from

Hard Graft In plants, it is not clear whether heritable changes can be induced by tissue grafting—for example, when one plant is grafted onto a different root stock. Stegemann and Bock (p. 649 ) now show that genetic material is transferred between

Allopolyploidization, the combination of the genomes from two different species, has been a major source of evolutionary innovation and a driver of speciation and environmental adaptation. In plants, it has also contributed greatly to crop domesticat

Presence and possible functions of DNA methylation in plastid genomes of higher plants have been highly controversial. While a number of studies presented evidence for the occurrence of both cytosine and adenine methylation in plastid genomes and pro

The functions of several small subunits of the large photosynthetic multiprotein complex PSI (Photosystem I) are not yet understood. To elucidate the function of the small plastome-encoded PsaJ subunit, we have produced knockout mutants by chloroplas

Eukaryotic cells arose through the uptake of free-living bacteria by endosymbiosis and their gradual conversion into organelles (plastids and mitochondria). Capture of the endosymbionts was followed by massive translocation of their genes to the geno

Chloroplast RNA editing proceeds by C-to-U transitions at highly specific sites. Here, we provide a phylogenetic analysis of RNA editing in a small plastid gene, petL, encoding subunit VI of the cytochrome b6f complex. Analyzing representatives from
