Full-Length Transcriptome Analysis of the ABCB, PIN/PIN-LIKES, and AUX/LAX Families Involved in Somatic Embryogenesis of Lilium pumilum DC. Fisch.

ABSTRACT: Plant cell totipotency is one of the 25 major topics in current scientific research, and somatic embryos are good experimental material for studying cell totipotency. Polar auxin transport plays an important regulatory role in somatic embryogenesis (SE). However, little is known about the auxin transport genes and their regulatory mechanisms in Lilium SE. In this study, we applied single-molecule real-time (SMRT) sequencing to Lilium pumilum DC. Fisch. for the first time and obtained a total of 119,649 transcripts, of which 14 encoded auxin transport genes. Correlation analyses between somatic embryo induction and gene expression under different treatments revealed that auxin transport genes, especially ATP-binding cassette (ABC) transporter B family member 21 (ABCB21)
