title: GSM5418783: T1; Populus deltoides x Populus x canadensis; RNA-Seq
library_construction_protocol: After removing the leaves, basal stems (2 cm) were sampled for RNA isolation. Thirty plants for each line were pooled as a sample and three biological replication were set. RNA purification, library construction and sequencing were conducted by Shanghai Applied Protein Technology Co., Ltd. (Shanghai, China). RNA libraries were prepared for sequencing using standard Illumina protocols
