Abstract

The evolution of the symbiotic association with microbes allowed termites to decompose ingested lignocellulose from plant derived substrates, including herbivore dung and soil humus. However, some aspects of lignocelulose digestion of higher termites remain unknown. Representatives of Termitidae range in their feeding habits from wood and litter-feeding to humus-feeding species. These insects constitute an excellent group to evaluate questions about lignocellulose digestion in the context of evolution and adaptation to the environments. However, only limited information is available about the feeding ecology of neotropical higher termites. The main objective of this research project is to investigate aspects of lignocellulose digestion and symbiont community in the gut of termites through enzymatic bioassays and Illumina sequencing of the 16S rRNA gene and transcriptomics. We will determine i) the bacterial community, enzymatic activity and transcriptome of the facultative lichen-feeder termite Constrictotermes cyphergaster and ii) the functional composition of gut microbiota of the humus-litter feeders Procornitermes araujoi e Silvestritermes euamignathus, after feeding with different components of the lignocellulose. We expect that lichen ingestion affect the composition and functionality of the microbiota of C. cyphergaster. In addition, we expect that intermediate feeders could modulate their gut microbiota and digestive capability after diet variation more efficiently because their higher gut bacteria diversity. The results of this research project will be important to the understanding of relationship of higher termites and their gut symbionts. (AU)
