Other claims from this paper (7)

Method / resource A total of 312,302 SSR molecular markers were identified across the Chinese chestnut genome
Method / resource After polymorphism screening, 138,208 polymorphic SSR loci were obtained in Chinese chestnut
Method / resource Only six primer pairs were required to create a unique DNA fingerprint of ancient chestnut trees
Method / resource The developed SSR markers had a polymorphic information content of 0.859 in Castanea
Method / resource Cluster analysis showed that Castanea resources can be well differentiated with the developed markers
Recommendation The developed markers can be widely used to identify interspecific boundaries in Castanea (author recommendation)
Recommendation The developed markers have potential for assessing genotypic diversity in chestnut (author interpretation)
