Resumen:
A considerable number of soil and rhizospheric fungi and bacteria collectively known as plant growth promoting
microorganisms (PGPM) have demonstrated ability to colonize plant roots and to provide benefits
to their hosts. Among these benefits, many authors documented improved root hydraulic conductance
and alleviation of abiotic stresses such as drought and salinity. Today, it is accepted that movement
through aquaporins represents a quite faster pathway of water movement across biological membranes.
This review is intended to reflect the state of art in the knowledge of PGPM effects on plant water status
and root hydraulic conductance, with special emphasis on the experimental data that prove or suggest
an impact of PGPM on root aquaporins under both normal and water limiting conditions.
