abstract = {A non-invasive plant phenotyping platform, GrowScreen-PaGe,
was used to resolve the dynamics of shoot and root growth of
the model cereal Brachypodium (Brachypodium distachyon
Bd21-3) in response to the plant growth promoting (PGP)
bacteria Azospirillum (Azospirillum brasilense Sp245).
Inoculated Brachypodium plants had greater early vigor and
higher P use efficiency than non-inoculated Brachypodium at
low P and low temperature conditions. Root systems were
imaged non-invasively at eight time points and data combined
with leaf area, shoot biomass and nutrient content from
destructive subsamples at 7, 14 and 21 days after
inoculation (DAI). Azospirillum colonisation of roots
improved Brachypodium shoot and, to a greater degree, root
growth in three independent experiments. Inoculation
promoted P use efficiency in shoots but not P concentration
or uptake, despite increased total root length. Longer roots
in inoculated plants arose from twofold faster branch root
growth but slower axile root growth, detected at 11 DAI.
Analysis of the spatio-temporal phenotypes indicated that
the effects of Azospirillum inoculation increased as shoot P
concentration declined, but the magnitude depended on the
time after inoculation and growth rate of branch roots
compared to axile roots. High throughput plant phenotyping
platforms allow the details of plant-microorganism symbioses
to be resolved, offering insights into the timing of changes
in different tissues to allow molecular mechanisms to be
determined},
