Description
Summary:	The Brassicaceae are an important family of about 338 genera distributed worldwide. It includes several species of crops, weeds, ornamentals, and the model organism Arabidopsis thaliana (L.) Heynh. Capsella bursa-pastoris (L.) Medik. And Capsella rubella Reut. belong to a small genus with only three species. Capsella species are closely related to the model organism Arabidopsis thaliana ( Couvreur et al., 2010 ). Capsella rubella is diploid (2 n = 2 x = 16). It grows around the Mediterranean Sea, and, more occasionally, in America and Australia where it was introduced ( Hurka and Neuffer, 1997 ). Capsella rubella has been described as a highly selfi ng plant ( Hurka et al., 1989 ) and has attracted attention as a model system for comparative genomic studies in crucifers ( Boivin et al., 2004 ). Complete genomic sequencing of C. rubella is under way, and sequences are currently available on the NCBI Trace archive www.ncbi.nlm.nih.gov/Traces/home/). Capsella bursa-pastoris (shepherd ' s purse) is tetraploid (2 n = 4 x = 32). It is distributed in ruderal habitats all over the world except in the tropics ( Hurka and Neuffer, 1997 ). Capsella bursa-pastoris is a predominantly selfi ng species with a fl exible mating system ( Hurka et al., 1989 ). Genetic variation in Capsella has been investigated using enzyme systems ( Hurka and Neuffer, 1997 ) and, more recently, gene sequencing ( Slotte et al., 2008 ). Genetic variation was found to be low, especially in C. rubella. To explore genetic variation using highly polymorphic markers, we developed 17 microsatellite loci.
