Proportions of retroelements found in redundant STCs, nonredundant STCs, and genomic sequences from Arabidopsis and rice. Transposable element homologies were identified as described in text. Classification of Arabidopsis chromosome 2 transposable elements was obtained from the chromosomal annotation (Lin et al. 1999). Total observed homologs are as follows: Nonredundant STCs: 350 rice transposases, 2754 rice retroelements; 101 Arabidopsistransposases, 628 Arabidopsis retroelements. Redundant STCs: 821 rice transposases, 6027 rice retroelements; 143Arabidopsis transposases, 1197 Arabidopsisretroelements. Genomic DNA: 23 rice transposases, 45 rice retroelements; 159 Arabidopsis transposases, 404Arabidopsis retroelements.
