A Corrigendum on
Quantification and Localization of Formylated Phloroglucinol Compounds (FPCs) in Eucalyptus Species

by Dos Santos BM, Zibrandtsen JFS, Gunbilig D, Sørensen M, Cozzi F, Boughton BA, Heskes AM and Neilson EHJ (2019) Front. Plant Sci. 10:186. doi: 10.3389/fpls.2019.00186

Error in Figure/Table

In the original article, there was a mistake in Figure 4 and Supplementary Table S2 as published. There was an error during the FPCs quantification process, whereby the ratio of injection volume between sample and standard was accidentally inverted. This error has resulted in the overestimation of FPCs concentration reported, but does not alter the biological significance of the results. The corrected Figure 4 appears below, and Supplementary Table S2 has been replaced in the original article.

Furthermore, in the original article, there was an error in the results section where the number of total FPCs for different tissues of two species are cited.

A correction has been made to the Results section, sub-section Detection and Quantification of FPCs, paragraph four:

“From all species analyzed, E. camphora and E. globulus had the highest concentration of total FPCs in leaves, with 65 and 41mg g−1 DW, respectively (Figure 4, Supplementary Table S2). Eucalyptus camphora also had high concentration of FPCs in flower buds and flowers, with 13 and 12mg g−1 DW, respectively. Interestingly, three Eucalyptus species showed a tendency to accumulate more FPCs in flowers compared to the leaves. Eucalyptus leucoxylon, E. sideroxylon, and E. viminalis contained ~40, 5, and 3 times more total FPCs in the flowers compared to leaves, respectively Figure 4, Supplementary Table S2. Eucalyptus yarraensis presented very low amounts of FPCs in leaves and flower buds, and it is the only species that does not contain any sideroxylonals. Eucalyptus cladocalyx and C. ficifolia did not show any traces of this class of specialized metabolites in the tissues analyzed.”

Small letters represent statistical differences according to one-way ANOVA p < 0.050. (B) Relative FPCs concentration as percentage in respective tissues. t.d., traces detected; n.d., not detected.

In addition, there was an error in the discussion where the number of total FPCs concentration is cited again.

A correction has been made to the Discussion section, sub-section Qualitative and Quantitative FPCs Variation in Eucalyptus, paragraph three:

Eucalyptus camphora and E. globulus presented high concentrations of total FPCs in expanded leaves, with 65 and 41 mg g−1 DW, respectively. These concentrations are in a similar range to previous reports. For example, the concentration of sideroxylonals have been reported to reach up to 52 mg g−1 DW in E. melliodora (Wallis et al., 2002) and up to 100 mg g−1 DW in E. loxophleba ssp. lissophloia (Wallis and Foley, 2005).”

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
