Genome and secretome analysis of jute endophyte Grammothele lineata strain SDL-CO-2015-1: Insights into its lignocellulolytic structure and secondary metabolite profile.

Grammothele lineata strain SDL-CO-2015-1, jute (Corchorus olitorius) endophyte has been reported to produce anti-cancer drug paclitaxel in culture condition. Here we investigated the genome using different bioinformatic tools to find its association with the production of commercially important compounds including taxol. Carbohydrate-active enzymes, proteases, and secretory proteins were annotated revealing a complex endophytic relationship with its plant host. The presences of a diverse range of CAZymes including numerous lignocellulolytic enzymes support its potentiality in biomass degradation. Genome annotation led to the identification of 28 clusters for secondary metabolite biosynthesis. Several biosynthesis gene clusters were identified for terpene biosynthesis from antiSMASH analysis but none could be specifically pinned to taxol synthesis. This study will direct us to understand the genomic organization of endophytic basidiomycetes with a potential for producing numerous commercially important enzymes and secondary metabolites taking G. lineata as a model.
