Figure: Genetic exchange of paternal and maternal traits typically occurs over
the entire length of a chromosome.

The ideal crop plant is delicious and productive, while also resistant to pests and
diseases.
CRISPR/Cas molecular scissors allow for targeted editing, insertion or inhibition
of genes in plants.
Now, researchers have been able to stop gene exchange
.
Learn from nature: Chromosome engineering prevents gene exchange
In their research, the scientists followed nature's example
.
In collaboration with Professor Andreas Houben of the Leibniz Institute of Plant Genetics and Crop Plants (IPK), Puchta and his team flipped the chromosomes of the model organism Arabidopsis thaliana (mustard) by nine-tenths
.
Make it possible to grow more efficient and robust crop plants in the future
In order to effectively cultivate crops, it is important
to combine as many favorable traits as possible in one plant.
