Transcriptional analysis of sexual versus asexual planarians. Ratio-intensity (R-I) scatter plot depicting the results of oligonucleotide microarray comparing gene expression between mature sexual planarians (Sx) and asexual (Asex) planarians. Standard deviation (SD); in situ hybridization (ISH); transcripts that showed upregulation (≥ 2 SD) in sexuals (black triangles); transcripts that showed upregulation (≥ 2 SD) in asexuals (yellow triangles); transcripts from primary in situ hybridization screen that were expressed in the planarian reproductive system (green circles); transcripts characterized in this study (purple squares); transcripts showing changes ≤ 2 SD (white squares).
