Abstract

Though the volatile profiles of black pepper have been reported already, the information on terpene synthase family genes is not known. In this study, using a combinatorial approach, the berry hybrid transcriptome assembly of llumina and nanopore sequencing, the entire terpene synthase family responsible for the biosynthesis of the flavor-imparting volatiles in black pepper berries was profiled. The profile shows 98 terpene synthases from various terpene synthesis pathways. Three important monoterpene synthases were also validated by targeted amplification, sequencing and homology modeling. This study provides the first of its kind information on the terpene synthase family profile in Piper nigrum, which is potentially a major step for further characterization of the functional terpene synthase genes in black pepper.
