Just as humans cannot live without oxygen, so a tropical forest cannot be without termites. My Ph.D. study is focusing on understanding the functioning of dead phytomass degradation by termites. Termites need a specific microbiota in their gut and the only way to obtain information about prokaryotes and eukaryotes in termite's gut is to use molecular methods such as nucleic acid extraction, sequencing, and subsequent data processing, where bash and python become indispensable helpers.

Machadotermes is one of the basal Apicotermitinae genera, living in tropical West Africa. Old observations suggested the presence of a new gland, the intramandibular gland, in Machadotermes soldiers. Here, by combining micro-computed tomography, optical and electron microscopy, we showed that the gland exists in Machadotermes soldiers only as an ac...

Termites are social cockroaches that appeared about 150 million years ago. Nowadays, they are one of the main decomposers of dead plant tissues in tropical and subtropical regions. They digest lignocellulose, the principal component of plant tissues, with the help of rich communities of hindgut microbes composed of Bacteria, Archaea, and protists. The degradation of lignocellulose is performed by microbial Carbohydrate-Active enzymes (CAZymes) involved in the cleavage of complex carbohydrates. While the identity of the microbial CAZymes present in the hindgut of termites is known, the evolutionary history of these CAZymes with termites is unknown. We sequenced the gut metagenomes of 202 termite species representative of the ecological and taxonomic diversity of termites and studied the evolution of 259 CAZyme gene families. These CAZymes included glycoside hydrolases (GHs), glycosyltransferases (GTs), carbohydrate esterases (CEs), polysaccharide lyases (PLs), carbohydrate-binding module (CBM), and enzymes with auxiliary activities (AAs). We generated phylogenetic trees of prokaryotic CAZymes found in the termite gut together with non-termite CAZymes from the CAZy, GTDB, and NCBI databases. Using these phylogenetic trees, we will describe the evolution of termite gut prokaryotic CAZymes since termites came to be 150 million years ago.
