Plants have been living together with microbes (including bacteria,
nematodes and fungi) in the soil for millions of years. Both groups
of organisms interact with each other. For example, many microbes feed
on dead and live plant matter or plant exudates. Other microbes manage
to invade plants and feed on their resources. Still others provide nutrients
for plants that the plant could not otherwise access. Examples of these
symbionts are symbiotic nitrogen fixing bacteria that form nodules on
the roots of legume plants, and mycorrhizal fungi that can mine phosphorus
for plants. These plant-microbe interactions have important impacts
on agriculture and forestry.
Just as the human immune system protects us from infections by bacteria,
plants would be taken over by bacteria if they didn't have systems to
keep microbes at bay. During evolution, microbes and plants have developed
chemical communication systems that signal each other who is there,
what they want and the response of the partner. Often, the outcome of
signal interaction is the development of new root structures harboring
symbiotic or pathogenic microbes. Examples of these are: root nodules
inhabited by nitrogen-fixing bacteria; nematode-induced root galls;
tumours formed by Agrobacterium or arbuscular structures formed by mycorrhizal
fungi.
A central question in our research is how microbial signals orchestrate
plant responses to form a new root structure. Have microbes "hijacked"
or learned to mimic plant signals to manipulate root development?
Our recent work includes studies on the molecular mechanism of root
nodule development and focuses on the role of plant hormones and flavonoids
in regulating nodule development. Further research shows that nodule
formation overlaps in its development and possible regulation with lateral
root development and root gall development induced by parasitic nematodes.
This has led to the hypothesis that microbes might hijack developmental
signals used by plants to regulate their own development. Techniques
used to study the responses in plants to divert signals from microbes
include in situ hybridisation; light, fluorescence and confocal microscopy;
microspectrofluorometry and high pressure liquid chromatography.
More recently, Proteome Analysis has been used to compare the simultaneous
accumulation of hundreds of plant proteins in response to a variety
of bacterial signalling molecules. This technique makes use of two-dimensional
gel electrophoresis and mass spectrometry to display and identify large
numbers of proteins at a time. Proteome Analysis has given new insights
into the defence systems and developmental responses of plants to microbes.
