Plants harbour a wide diversity of microorganisms that
efficiently colonize different internal and external plant
organs and compartments, including the phyllosphere
(above-ground plant surface), spermosphere (seeds and
area surrounding seeds), endosphere (internal tissues)
and rhizosphere (roots and soil in the vicinity of plant
roots), establishing complex and dynamic interactions
with the host plants (Trivedi et al., 2020). The plant microbiome
plays major roles in the nutrition, growth and resistance
against biotic and abiotic threats (Trivedi
et al., 2020; Bakker and Berendsen, 2022; Yuan
et al., 2022) and there is complex communication
between microorganisms and their plant hosts (Berlanga-
Clavero et al., 2020; Rico-Jiménez et al., 2022). Indeed,
the secretion of a great variety of plant compounds
directs the assembly of plant-associated microbial communities
and it has been proposed that plants produce a
range of chemical signals to selectively recruit specific
microorganisms in order to assemble protective
microbiomes that enable them to cope with the imposed
biotic and abiotic stresses (Rizaludin et al., 2021; Rolli
et al., 2021; Trivedi et al., 2022). As a consequence of
this selective pressure exerted by the plants, the microbial
composition of the rhizosphere and the non-rooted
bulk soil differ – with the rhizosphere having a larger
microbial abundance but lower diversity (Berlanga-
Clavero et al., 2020; Sokol et al., 2022).
