Number of additional amino acids in the interior protein isoforms in a) rice chromosome 10 and b) Arabidopsis chromosome 4. ‘Min’ and ‘max’ are the minimum and maximum number of additional amino acids, respectively; p15, p30, and p50 are the cumulative proportions of interior variants with additional number of amino acids ≤ 15, ≤ 30, and ≤ 50, respectively.
