"Using DNA sequencing techniques that can decode the complete genome of an organism in one go (so-called ‘whole genome sequencing’) the researchers analyzed ‘clones’ of the small flowering plant ‘thalecress’ (Arabidopsis). They found that observable variations in regenerant plants are substantially due to high frequencies of mutations in the DNA sequence of these regenerants, mutations which are not contained in the genome of the parent plant."
Why plant 'clones' aren't identical
