Table 1.

Distribution of the selected microsatellite motifs in Jatropha transcriptomic sequences. Unclustered sequences refer to the raw EST files, while upon clustering, sequences were distributed in ‘Singlets’ and ‘Contigs’, as refered in the text. Microsatellite motifs shown in the table below were selected on the basis of the published reports on their preferential occurrences. Motifs AG/CT are known to be abundant in UTRs, AT/TA, AAT/TTA and AAAT/ATTT are generally most abundant motif types of their categories (di-, tri- and tetra-nucleotide) in the genomes, in non-coding DNA, AAG/CTT are generally most abundant repeats in exons, CCG/CGG are most common repeats in some species (mostly monocots) and motifs GC/CG are extremely rare
