  • Title: Bioinformatic analysis of microbial type terpene synthase genes in plants.
    Author: Chen X, Han J, Chen F.

    Abstract:
    Plants are prolific producers of terpenoids. Terpenoid biosynthesis is initiated by terpene synthases (TPS). In plants, two types of terpenes synthase genes are recognized: typical plant TPS genes and microbial-terpene synthase like-genes (MTPSL). While TPS genes are ubiquitous in land plants, MTPSL genes appear to be restricted to non-seed land plants. Evolutionarily, TPS genes are specific to land plants, whereas MTPSL genes have related counterparts in other organisms, especially fungi and bacteria. The presence of microbial type TPS in plants, fungi and bacteria, with the latter two often being associated with plants, poses a challenge in accurately identifying bona fide MTPSL genes in plants. In this chapter, we present bioinformatic procedures designed to identify MTPSL genes in sequenced plant genomes and/or transcriptomes. Additionally, we outline validation methods for confirming the identified microbial-type TPS genes as genuine plant genes. The method described in this chapter can also be adopted to analyze microbial type TPS in organisms other than plants.
