In the original article, there was a mistake in the legend for Figure 2 as published. The part labels for nodules induced by RL3841 and RLgmcA(pBBRgmcA) were incorrect. The correct legend appears below:
“Structure of 4-week-old pea nodules and bacteroids. Nodules were induced by RLgmcA(pBBRgmcA) (A,D), RLgmcA (B,E), RL3841 (C,F). The wild-type RL3841 forms normal spherical (determinant) nodules (C), while the gmcA mutant forms elongated nodules (B). PHB, poly-β-hydroxybutyrate. S, senescing bacteroid. Scale bars = 200 μm (A–C) and 1 μm (D–F).”
In the original article, there was an error in the text. In the Results section, the citation for Figure 2 contained the wrong part labels. A correction has been made to Results, The Symbiotic Phenotype ofR. leguminosarum Strains, paragraph 2:
“Four-week-old nodules were further examined by both light and electron microscopy. The nodules induced both by wild type RL3841 and by mutant RLgmcA turned blue when stained with toluidine blue. These observations were corroborated by light microscopic analysis. Both the nodules were filled by Rhizobia-infected cells (Figures 2B,C). The ultrastructural structure of the infected cells was observed by transmission electron microscopy. In the mutant infected nodule cells, bacteroids underwent premature senescence. Bacteroids in pea plants inoculated by R. leguminosarum bv. viciae usually did not produce visible PHB granules, but in the mutant bacteroids, the poly-b-hydroxybutyrate (PHB) was also distinctly observed (Figure 2).”
In the original article, there was a mistake in Table 4 as published. The strain names LMB599 and LMB675 were wrong; the correct strain names are RLgmcA and RLgmcA(pBBRgmcA), respectively. The corrected Table 4 appears below:
Table 4
| Strain | Nodules per plant | Acetylene reduction (μ moles acetylene per plant per h) | Dry weight per plant (g) |
|---|---|---|---|
| RL3841 | 137.3 ± 13.2a | 2.24 ± 0.14a | 1.86 ± 0.20a |
| RLgmcA | 131.3 ± 11.3a | 1.56 ± 0.05b | 1.10 ± 0.18b |
| RLgmcA(pBBRgmcA) | 135.5 ± 11.3a | 2.12 ± 0.16a | 1.80 ± 0.16a |
| WC | 0 | 0 | 0.35 ± 0.09c |
Symbiotic behavior of R. leguminosarum gmcA mutant.
All data are averages (±SEM) from ten independent plants.
Different letters indicates the value is significantly different from that of the wild-type RL3841 control (one-way ANOVA, P < 0.05). WC, water control without inoculation.
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
