a The Tajima relative rate test was used to examine the equality of the evolutionary rate between rubber tree paralogues; b Mt is the sum of the identical sites in all three sequences tested; c M1 is the number of unique differences in the first paralogue; d M2 is the number of unique differences in the second paralogue; e If p < 0.05, the test rejects the equal substitution rates between the two duplicates and infers that one of the two duplicates has an accelerated evolutionary rate.
