ABSTRACT:
Legumes form symbioses with arbuscular mycorrhizal fungi (AMF) and
rhizobia. The presence of one microbial symbiont has been recognized
to affect the activity of the other, and the interaction of both can
be detected through effects on the host plant. Such an interaction
forms the so-called tripartite symbiosis, for which beneficial effects
on nodulation and N2-fixation have been assumed to rely completely on
increased supply of phosphorus to the plant through the mycorrhizas.
After providing a working model for the establishment of the
tripartite symbiosis, the main objective of this thesis was to
investigate whether the process is regulated by phosphorus. A
multi-year field experiment was conducted with soybean (Glycine max
(L.) Merr.), and indigenous AMF treatments were produced by either
disrupting or leaving intact the extra-radical mycelium while the
potential of bradyrhizobia (Bradyrhizobium japonicum (Kirchner)
Jordan) was kept constant. The results indicated that even though
nodulation was enhanced when the mycorrhizal colonization was elevated
at 10 days after emergence, N2 fixation was not affected at later
periods of growth. Nevertheless, the P levels in soil and all plant
parts, as well as the soil acid and alkaline phosphatase activity were
similar irrespective of AMF treatment, showing that the establishment
of the tripartite symbiosis was not regulated by P. Therefore,
communication between the symbionts was clearly the next factor to be
tested and, for the remainder of the thesis, the objective was to
determine which flavonoids play a role in the establishment of the
tripartite symbiosis. Patterns of root accumulation of specific
flavonoids and the extent to which early effects of the tripartite
symbiosis would have at later periods of growth were evaluated over
three experiments under controlled environmental conditions. The root
accumulation of the flavonoids daidzein, genistein and coumestrol
diminished in response to the symbionts and N2 fixation was enhanced
by the tripartite symbiosis. Furthermore, AMF with different
colonization strategies had different impacts on the early development
of the tripartite symbiosis but N2 fixation was identical irrespective
of the fungus present.
