\"kenji<\/a>The mutually beneficial relationship between legumes and rhizobia, the nitrogen-fixing soil bacteria that make their home in legume root nodules and create nutrient-rich fertilizer for them, is one of the most well-known and agronomically important examples of symbiosis. New research from Dr. Kenjiro Quides<\/a>, a Postdoctoral Teaching and Research Fellow in the Grand Challenges Initiative<\/a> at Chapman University, tested the boundaries of this relationship \u2014 and found that it\u2019s not always as perfectly harmonious as previously thought.<\/p>\n

The results are reported in a new paper in the journal Evolution<\/em><\/a>.<\/p>\n

Legumes provide carbohydrates for rhizobial bacteria that live in root nodules, while the rhizobia fix atmospheric nitrogen into a form that’s usable for the legume (nitrogen is often a limiting nutrient for plants). In theory, if legumes have greater root nodule growth, they should be able to host more rhizobia, which should produce more nitrogen and enable larger plant growth in general.<\/p>\n

The research, carried out by Quides and colleagues at UC Riverside during his doctorate, tested the relationship between root nodule growth and rhizobia using a smaller relative of Soybeans, named Lotus japonicus<\/em>. By using multiple genetic variants that formed a low, medium, and high number of nodules, the study showed that legumes grew to maximum size when a low and medium number of nodules formed, but legumes that formed a high number of nodules had drastically reduced growth.<\/p>\n

The investigation then turned to the rhizobia. The size of the rhizobial population, a standard measure of bacterial growth, was found to continue to increase as the number of nodules formed increased. This suggests a hidden conflict in the symbiotic relationship. It seems that the legume and rhizobia interests are only aligned until the host optimum is reached, a point at which their interests diverge. This provides support for the conclusion that in the symbiotic relationship, rhizobia have an evolutionary advantage.<\/p>\n

The results demonstrate that to avoid conflict in symbiotic relationships, hosts must tightly regulate their investment into symbiotic organs (like legumes\u2019 root nodules) to maximize their own benefit-to-cost ratio of associating with their symbiotic partner.<\/p>\n

\u201cLegumes seem to play a balancing act to maximize their growth, but rhizobia continue to grow and that is a really exciting result,\u201d Dr. Quides said. He noted that this study opens the door to more research. \u201cAlthough we found diminishing returns for the host from nodulation, the fact that rhizobia population size continued to increase is promising. We found the costs outweigh the benefits at high nodule numbers. However, if we can increase the number of nodules and therefore the rhizobia population size while minimizing the cost to the plant, we have the potential to increase the productivity of legume crops in the future.\u201d<\/p>\n

Dysregulation of host\u2010control causes interspecific conflict over host investment into symbiotic organs<\/em> is available online at: https:\/\/doi.org\/10.1111\/evo.14173<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
