Abstract
Plant in vitro culture techniques are highly useful to obtain signifcant amounts of true-to-type and disease-free
plant materials. One of these techniques is clonal micropropagation which consists on the establishment of shoot tip cultures, shoot multiplication, in vitro rooting and acclimatization to ex vitro conditions. However, in some cases, the existence of recalcitrant genotypes, with a compromised multiplication and rooting ability, or the difculties to overcome the
overgrowth of endophytic contaminations might seriously limit its efciency. In this sense, the establishment of benefcial
interactions between plants and plant growth-promoting microorganisms (PGPMs) under in vitro culture conditions might
represent a valuable approach to efciently solve those restrictions. During the last years, signifcant evidence reporting the
use of benefcial microorganisms to improve the yield of in vitro multiplication or rooting as well as their acclimatization
to greenhouse or soil conditions have been provided. Most of these positive efects are strongly linked to the ability of these
microorganisms to provide in vitro plants with nutrients such as nitrogen or phosphorous, to produce plant growth regulators, to control the growth of pathogens or to mitigate stress conditions. The culture of A. thaliana under aseptic conditions
has provided high-quality knowledge on the root development signaling pathways, involving hormones, triggered in the
presence of PGPMs. Overall, the present article ofers a brief overview of the use of microorganisms to improve in vitro
plant performance during the in vitro micropropagation stages, as well as the main mechanisms of plant growth promotion
associated with these microorganisms
