Opium poppy is one of the most important medicinal plants and remains the only commercial resource of morphinan-based painkillers. However, little is known about the regulatory mechanisms involved in benzylisoquinoline alkaloids (BIAs) biosynthesis in opium poppy. Herein, the full-length transcriptome dataset of opium poppy was constructed for the first time in accompanied with the 33 samples of Illumina transcriptome data from different tissues, growth phases and cultivars. The long-read sequencing produced 902,140 raw reads with 55,114 high-quality transcripts, and short-read sequencing produced 1,923,679,864 clean reads with an average Q30 rate of 93%. The high-quality transcripts were subsequently quantified using the short reads, and the expression of each unigene among different samples was calculated as reads per kilobase per million mapped reads (RPKM). These data provide a foundation for opium poppy transcriptomic analysis, which may aid in capturing splice variants and some non-coding RNAs involved in the regulation of BIAs biosynthesis. It can also be used for genome assembly and annotation which will favor in new transcript identification.
