Transcriptome analysis of the endangered Notopterygium incisum: Cold-tolerance gene discovery and identification of EST-SSR and SNP markers

Notopterygium incisum C. C. Ting ex H. T. Chang (Apiaceae) is an endangered perennial herb in China. The lack of transcriptomic and genomic resources for N. incisum greatly hinders studies of its population genetics and conservation. In this study, we employed RNA-seq technology to characterize transcriptomes for the flowers, leaves, and stems of this endangered herb. A total of 56 million clean reads were assembled into 120,716 unigenes with an...
