Abstract

Several intragenically linked microsatellites have been identified in the floral regulatory genes A. sandwicense APETALA1 (ASAP1) and A. sandwicense APETALA3/TM6 (ASAP3/TM6) in 17 species of the Hawaiian and North American Madiinae (Asteraceae). Thirty-nine microsatellite loci were observed in the introns of these two genes, suggesting that they are hotspots for microsatellite formation. The sequences of four of these microsatellites were mapped onto the phylogenies of these floral regulatory genes, and the structural evolution of these repeat loci was traced. Both nucleotide substitutions and insertion/deletion mutations may be responsible for the formation of perfect microsatellites from imperfect repeat regions (and vice versa).
