Description review article
Drought is a critical factor limiting the productivity of legumes worldwide. Legumes
can enter into a unique tripartite symbiotic relationship with root-nodulating bacteria
of genera Rhizobium, Bradyrhizobium, or Sinorhizobium and colonization by arbuscular
mycorrhizal fungi (AMF). Rhizobial symbiosis provides nitrogen necessary for growth.
AMF symbiosis enhances uptake of diffusion-limited nutrients such as P, Zn, Cu, etc.,
and also water from the soil via plant-associated fungal hyphae. Rhizobial and AMF
symbioses can act synergistically in promoting plant growth and fitness, resulting in
overall yield benefits under drought stress. One of the approaches that rhizobia use
to survive under stress is the accumulation of compatible solutes, or osmolytes, such
as trehalose. Trehalose is a non-reducing disaccharide and an osmolyte reported to
accumulate in a range of organisms. High accumulation of trehalose in bacteroids
during nodulation protects cells and proteins from osmotic shock, desiccation, and
heat under drought stress. Manipulation of trehalose cell concentrations has been
directly correlated with stress response in plants and other organisms, including AMF.
However, the role of this compound in the tripartite symbiotic relationship is not fully
explored. This review describes the biological importance and the role of trehalose in
the tripartite symbiosis between plants, rhizobia, and AMF. In particular, we review the
physiological functions and the molecular investigations of trehalose carried out using
omics-based approaches. This review will pave the way for future studies investigating
possible metabolic engineering of this biomolecule for enhancing abiotic stress tolerance
in plants.
