Comparison of different methods for the establishment of RNA silencing in plants
RNA interference (RNAi) occurs naturally in plants and is involved in developmental gene regulation as well as in transposon silencing and defence against viruses. RNAi is initiated by small double-stranded RN...

Elimination of agrobacteria from transgenic plants
Genetically engineered agrobacteria are routinely used to transform crop plants. These agrobacteria can obviously persist within the transgenic plants although they are not tumorgenic [1–4]. Our attempts to el...

Expression of phosphinothricin acetyltransferase from the root specific par promoter in transgenic tobacco plants is sufficient for herbicide tolerance
The pat gene, coding for phosphinothricin acetyltransferase (PAT) from Streptomyces viridochromogenes, was cloned behind the par promoter of the hemoglobin gene from Parasponia andersonii, Introduction into tobac...

Functioning haemoglobin genes in non-nodulating plants
Haemoglobin has previously been recorded in plants only in the nitrogen-fixing nodules formed by symbiotic association between Rhizobium or Frankia and legume or non-legume hosts11–4. Structural similarities amon...

Genetic Variation and Horizontal Gene Transfer: Prospects of Research of a Group Installed at the “Biologische Bundesanstalt”
A way to define a relevant concept for research on risk assessment of deliberate releases of genetically engineered microorganisms is described. Established risk assessment schemes are used to highlight proble...

Common evolutionary origin of legume and non-legume plant haemoglobins
The detection of haemoglobins in distantly-related non-legume plant families1,2 as well as in the legume families raises the question of whether the origin of the plant haemoglobins was single or multiple, We hav...
