Development of SSR markers for the genus Patellifolia (Chenopodiaceae).
OBJECTIVE
Microsatellite primers were developed to promote studies on the patterns of genetic diversity within Patellifolia patellaris (Chenopodiaceae) and the relationship between the three species of the genus Patellifolia.


RESULTS
The genomic sequence from P. procumbens was screened for simple sequence repeats (SSRs), and 3648 SSRs were identified. A subset of 53 SSR markers was validated, of which 25 proved to be polymorphic in the three species except for the P. webbiana-specific marker JKIPat16. The number of alleles ranged from 85 in P. patellaris, 187 in P. procumbens, and 202 in P. webbiana.


CONCLUSIONS
The set of 25 new markers will facilitate studies of the relationships between the three Patellifolia species and of the spatial and temporal distribution of genetic diversity within the species.
