Tissue culture results (left) and origins of solid blue mutations (right).

<p>Percentages were calculated based on the results of medium and highly variegated plants. Solid blue was the most frequent form of somaclonal variations of ‘Thamires.’ Most of these variations were derived from newly induced mutations arising from the tissue culture process. The numbers in this figures are calculated by the result of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0023541#pone-0023541-t001" target="_blank">Table 1</a>.^aTotal number of somaclonal variations should be include solid blue mutants, other phenotypes, and altered-variegation mutants. ^bOthers include periclinal chimeras and solid pink mutants.
