Ferula gummosa Boiss from the Apiaceae family is native to East and West of Iran. Galbanum is an oleo-gum-resin with high pharmaceutical and industrial values, which is exuded from F. gummosa in response to wounds. Although galbanum ranks first in terms of Iranian export of pasture medicinal plants, but little information on the genetic and biochemical mechanisms of these compounds are existed. RNA-Seq techniques are now one of the most used and most accurate methods in transcriptomics. In the present study, RNA-Seq was used to evaluate the root and flower of F. gummosa transcriptome. Short reads obtained from Illumina HiSeq2000 were assembled by Trinity. The assembled transcriptome with 158,436 transcripts and N50 1,348 bp was annotated using different databases. In total, 100,275 transcripts were annotated using BLASTX with an E-value cut-off of 10-5. Gene ontology (GO) classification of annotated transcripts was done by Blast2Go and Trinotate pipeline and in total 73,678 transcripts with at least one GO were identified. In terms of biological processes, cellular and metabolic processes are the most GO terms indicated that the plant is in a metabolically active status. Transcriptome assessment of orthologous genes by NCBI-KOG database led to the identification of 42,452 genes from 3,925 families and 26 functional classes. The largest class of orthologous genes was associated with signal transduction mechanisms , followed by other classes such as secondary metabolites-transport and catabolism with a frequency of 4.25 % indicating an active status of F. gummosa roots and flowers for secondary metabolite production and transportation.
