Great write up, heres a teaser, trying to save space on server, follow link for full study.
1. INDRODUCTION
Surface polysaccharides and exudates of
plants are often the first point of contact
between foreign organisms and plants, in
addition to acting as mechanical scaffolding
to support land plants, or simple stored
energy sources. The ecological role of these
polysaccharides can be both positive and negative,
and in this review, we consider both
aspects, especially as revealed through the
use of synchrotron-based IR spectroscopy.
We briefly review the microbiological characteristics
of rhizosphere-associated microorganisms,
interactions with plant growth, and
some of the recent chemical communication
pathways (Quorum Sensing/quenching) identified
in the soil. From the plant perspective,
recent work in model genetic systems points
to two mechanisms whereby low-molecularweight
natural compounds may be excreted
into the root environment in response to pathogen
attack or abiotic stress
