  1. Mycorrhizal phosphate uptake pathway in tomato is phosphorus-repressible and transcriptionally regulated Volume 181, Issue 4, 950–959, Article first published online: 24 December 2008

Since its publication, the authors of Nagy et al. (2009) have become aware that Fig. 1(a) incorrectly shows the length of the root subsamples used to measure percentage colonization instead of total root length per pot. The corrected values are shown in the revised version of Fig. 1(a) printed here and correspond to the root dry weights in Supporting Information Fig. S1(b) in Nagy et al. (2009). Both figures reveal a similar relationship between root growth and different P conditions. In consequence, relationships between soil P level and colonization are similar irrespective of using root weight or root length as a basis. Total colonized root length was 95, 68 and 39 m for the three P levels and the corresponding values for root length with arbuscules were 65, 56 and 27 m.

Figure 1.

 Root length (a), root colonisation (b) and length of hyphae in soil (c) as influenced by inoculation with Glomus intraradices and by supply of 0, 20 or 60 mg P kg−1soil (P0, P20 and P60) to pots with Micro-Tom tomato (Solanum lycopersicum) plants. Light and dark grey bars in (a) and (c) represent data from pots with nonmycorrhizal and mycorrhizal conditions, respectively. Dark grey, light, and white bars in (b) represent total mycorrhizal structures, arbuscules, and vesicles, respectively. Means + SE, and bars with the same letter in (a) and (c) are not significantly different (< 0.05). In (b), identical comparison of means was made separately for each colonization variable.

Therefore, it still seems fair to conclude that root colonization and hyphal length density (HLD) are far less sensitive to increasing soil P than the specific activity of 33P.

We apologize to our readers for this mistake and are grateful for the comments of one attentive reader.
