Glycosylation plays a crucial role in many aspects of cell biology, including cellular and organismal integrity, structure-and-function of many glycosylated molecules in the cell, signal transduction, development, cancer, and in a number of diseases. Besides, at the inter-organismal level of interaction, a variety of glycosylated molecules are involved in the host-microbiota recognition and initiation of downstream signalling cascades depending on the outcomes of the glycome-mediated ascertainment. The role of glycosylation in host-microbe interactions is better elaborated within the context of virulence and pathogenicity in bacterial infection processes but the symbiotic host-microbe relationships also involve substantive glycome-mediated interactions. The works in the latter field have been reviewed to a much lesser extent, and the main aim of this mini-review is to compensate for this deficiency and summarise the role of glycomics in host-microbe symbiotic interactions.

Fungal symbionts play a key role in maintaining host homeostasis. In a recent issue of Nature, Liao et al. show that Kazachstania pintolopesii, a symbiotic fungus in mice, is shielded from the host immune system during homeostasis but induces type 2 immunity during mucus fluctuations.

Fungal-bacterial endosymbioses, the most intimate typology of symbioses, have been described in different taxa of Mucoromycota, an early diverging group of Fungi. In a recent issue of Nature, Giger and colleagues describe how they implanted a Burkolderia-related microbe inside a Mucoromycota fungus, giving rise to a functional and stable endosymbiosis.

The deep hydrocarbon fluids discharged into the water column at cold seeps create diverse and heterogeneous habitats on the seafloor. Symbiosis is essential for the survival of marine life in extreme deep-sea environments. Although the symbiotic relationship between chemoautotrophic bacteria and invertebrates has been reported, our understanding of these host-microbe interactions under heterogeneous environment remains limited.

The intracellular colonization of plant roots by the beneficial fungal endophyte Serendipita indica follows a biphasic strategy, including a host cell death phase that enables successful colonization of Arabidopsis thaliana roots. How host cell death is initiated and controlled is largely unknown. Here, we show that two fungal enzymes, the ecto-5'-nucleotidase SiE5NT and the nuclease SiNucA, act synergistically in the apoplast at the onset of cell death to produce deoxyadenosine (dAdo).

Humans maintain symbiotic relationships with complex microbial communities in their intestinal tracts that are paramount to their host's health and development. Given their importance, it is essential for the host to reliably acquire key members of the gut microbiota and assemble communities that provide benefits during important windows of host development. Epidemiological studies over the last 2 decades have convincingly shown that clinical and nutritional factors that disrupt early-life microbiome assembly predispose humans to infections and chronic noncommunicable diseases.
