Fig. 4From: Assessing the Extent of Substitution Rate Variation of Retrotransposon Long Terminal Repeat Sequences in Oryza sativa and Oryza glaberrimaDistribution of Kimura 2p nucleotide distances along O. sativa chromosome 3 short arm RefSeq for LTRs orthologous sequences. Black dots denote the nucleotide distance value (Y-axis) for each position. The red line is a nonparametric regression estimate of the local values. Black lines indicate upper and lower 95% confidence bounds on the smooth line computed assuming no positional preference (10,000 permutations). Position (X-axis) is expressed as nucleotides on the chromosome 3 short arm RefSeq. Centromere position is estimated at 1.94e+07 bp.Back to article page
