dc.description.abstract | Split-root systems (SRS) constitute an appropriate methodology for studying the relevance
of both local and systemic mechanisms that participate in the control of rhizobia-legume symbioses.
In fact, this kind of approach allowed to demonstrate the autoregulation of nodulation (AON)
systemic response in soybean in the 1980s. In SRS, the plant main root is cut and two lateral roots
that emerge from the seedlings after root-tip removal are confined into separate compartments. After
several days of growth, these plants have two separate roots that can be inoculated with the same or
with different bacteria, at the same or at different times. In this work, we have used a non-destructive
SRS to study two different competitiveness relations between rhizobial strains in soybean roots. One
of them is the competition for nodulation between two soybean-nodulating rhizobia: the slow-grower
Bradyrhizobium japonicum USDA110 and the fast-grower Sinorhizobium fredii HH103. The second
is the competitive blocking of S. fredii 257DH4 nodulation in the American soybean Osumi by
Sinorhizobium fredii USDA257, which is unable to nodulate American soybeans. Our results showed
that the competitiveness relationships studied in this work are mitigated or even avoided when the
competitive strains are spatially separated in different compartments containing half-roots from the
same plant, suggesting that competitive relations are more related to local plant responses. In our
opinion, split-root systems are an appropriate approach to further study competitive relations among
rhizobial strains. | es |
