Abstract Saussurea medusa, Saussurea hypsipeta and Saussurea obvallata are typical alpine snowline plants growing in the Qinghai-Tibet plateau. They are characterized by a specialized morphology. S. medusa and S. hypsipeta have very dense trichomes on whole plant, whereas S. obvallata has transparent bracts covered inflorescences. The different forms reflect their adaptation to cold environments. To investigate the different mechanisms of adaptation of these species to cold temperatures, transcriptome sequencing was performed in three species of Saussurea DC. A total of 116394 137237 and 113879 Unigenes were identified from S. medusa, S. hypsipeta and S. obvallata, respectively. Of these, 55909 (48.03%), 65519 (47.74%) and 51889 (45.56%) Unigenes… More >
