Low-copy nuclear genes

Given the paucity of nuclear genes used in Campanulaceae, we are trying to identify low-copy genes that may be informative, especially within the Campanuloideae.  We have now isolated two markers: GapC exons 7-9 (with introns 7-8) and NIA (Nitrate reductase, intron3) AND we have our first sequences!  We are also exploring PepC, Waxy, Leafy, ADH, and TM6. Who needs ITS? :-)
