When plant geneticists discover a gene that increases crop yields, they want to try inserting the same change into other crops
In a study published in the journal Nature Plants, Lippmann and former postdoc Cao Xu (now at the Chinese Academy of Sciences in Beijing) and colleagues show how diploidy in plant genomes enables crop developers The plan is complicated
Tweaking a gene in one plant can increase a desirable trait, but altering the same gene in another plant may not produce the same results
The team looked at the clv3 gene
In tobacco, the impact was significant, with some growing areas doubling in size
For Lippmann, the lesson is that optimizing crops through genome editing may require an inventory of repetitive genes
