“…90 is closely related to Fujimishiro except for root nodulation. In another potted plant experiment, Katayama et al (2010) showed that the number of root nodules of the R+ plants was 82.4 ± 8.6 (mean ± SE, n = 15), but there were no nodules on the roots of the R− plants ( n = 24). Also, foliar nitrogen and phenolics of the R+ plants were 50% higher and 12% lower than those of the R− plants in the presence of rhizobia.…”

1. Plants take nutrients for their growth and reproduction from not only soil but also symbiotic microbes in the rhizosphere, and therefore below‐ground microbes may indirectly influence the above‐ground arthropod community through changes in the quality and quantity of plants. 2. Rhizobia are root‐nodulating bacteria that provide NH4+ to legume plants. We examined bottom‐up effects of rhizobia on the community properties of the arthropods on host plants, using a root‐nodulating soybean strain (R+) and a non‐nodulating strain (R−) in a common garden. 3. R+ plants grew larger and produced a greater number of leaves than R− plants. We observed 28 species of herbivores and three taxonomic groups of predators on R+ and R− plants. The herbivorous species were classified into sap feeders (12 species) and chewers (16 species). 4. The species richness of overall herbivores, sap feeders, and chewers on R+ plants was greater than that on R− plants. Rhizobia positively affected the abundance of chewers. 5. The community composition of herbivores was significantly different between R− and R+ plants, although species diversity and evenness did not differ. 6. Rhizobia‐induced bottom‐up effects were transmitted to the third trophic level. The abundance, taxonomic richness, and diversity of the predators on R+ plants were greater but evenness was lower than those on R− plants. The community composition of predators was not affected by rhizobia. 7. These results indicate that the below‐ground microbes initiated bottom‐up effects on above‐ground herbivores and predators through trophic levels.

“…The enhanced species richness and abundance of insect herbivores are most likely due to increased foliar nitrogen in plants with rhizobia (Katayama et al, 2010).…”

“…Such beneficial processes of Rhizobium are affected by biotic factors like rhizosphere microbes (van Veen et al, 1997) as well as abiotic factors like soil fertility (Rotaru & Sinclair, 2009). Belowground colonization of roots by Rhizobium has been found to interact with aphids and other aboveground herbivores (Kempel et al, 2009;Katayama et al, 2010Katayama et al, , 2011Martinuz et al, 2012). For example, root colonization by Rhizobium has been found to promote plant resistance to insect pests (Thamer et al, 2011).…”

Rhizobium inoculant has been developed for bean production in Lake Victoria basin. Two types of compost have been developed, water hyacinth compost with cattle manure culture (H+CMC) or with effective microbes (H+EM). Influence of Rhizobium and composts on Aphis fabae and Colletotrichum lindemuthianum were investigated in the field. Rhizobium and hyacinth composts increased nodulation (×2 to 5); while Aphis fabae population increased (×2) on Rhizobium-inoculated plants with H+EM. Incidence of C. lindemuthianum was high in Rhizobium-inoculated plants. Plants that received diammonium phosphate (DAP) fertilizer had few nodules, reduced germination, slow growth and low yields. In conclusion, the water hyacinth composts contain beneficial microbes that promote root nodulation by Rhizobium, which is necessary for nitrogen fixation, while enhancing tolerance to aboveground infestations by A. fabae and C. lindemuthianum. We raise questions on our results to stimulate research, considering that bean breeding programs in Africa have mainly focused on microbial pathogens, and not insect pests.
