A Corrigendum on
Root symbiotic fungi improve nitrogen transfer and morpho-physiological performance in Chenopodium quinoa

By Alquichire-Rojas S, Escobar E, Bascuñán-Godoy L and González-Teuber M (2024). Front. Plant Sci. 15:1386234. doi: 10.3389/fpls.2024.1386234

In the published article, there was an error in the unit used for stomatal conductance, we wrote “g_s (nmol H₂O m^-2 s^-1)” where we meant g_s (mmol H₂O m^-2 s^-1). This error occurred in the Y axis title for Figure 4B, the caption for Figure 4, Table 1 caption and in a sentence of the Materials and methods, section 2.8 Plant photosynthetic and morphological parameters as published. This sentence previously stated:

“Gas exchange measurements of net photosynthesis (A_N) (µmol CO₂ m^-2 s^-1), stomatal conductance (g_s) (nmol H₂O m^-2 s^-1), and transpiration (T) (mmol H₂O m^-2 s^-1) were performed for fully expanded leaves (third leaf from the top) using a portable open gas exchange system (CIRAS-2, PP Systems Amesbury, MA, USA).”

The corrected sentence appears below:

“Gas exchange measurements of net photosynthesis (A_N) (µmol CO₂ m^-2 s^-1), stomatal conductance (g_s) (mmol H₂O m^-2 s^-1), and transpiration (T) (mmol H₂O m^-2 s^-1) were performed for fully expanded leaves (third leaf from the top) using a portable open gas exchange system (CIRAS-2, PP Systems Amesbury, MA, USA).”

The corrected Figure 4 and Table 1 are below:

Figure 4

Figure 4. Effects of nitrogen (N) level and EIPF inoculation on photosynthetic parameters in C. quinoa (A) net photosynthetic rate (μmol CO₂ m^-2 s^-1) (n = 4-6), (B) stomatal conductance rate (mmol H₂O m^-2 s^-1) (n = 4-6), and (C) transpiration rate (mmol H₂O m^-2 s^-1) (n = 4-6). Error bar labels with different letters indicate significant differences (P < 0.05) among treatments. 5 mM, low nitrogen level; 15 mM, high nitrogen level; EIPF-, non-inoculated plants; EIPF1+, inoculated with Beauveria; EIPF2+, inoculated with Metarhizium.

In the published article, there was also an error in the Funding statement; “Other funding was provided by ANID-Subdirección Capital Humano/Doctorado Nacional/2021-21210677 (SA-R)” was omitted.

The correct Funding statement appears below:

“The author(s) declare that financial support was received for the research, authorship, and/or publication of this article. This work was supported by grants ANID Fondecyt Regular N° 1230282 (MG-T) and ANID Fondecyt Regular N° 1211473 (LB-G). Other funding was provided by ANID-Subdirección de Capital Humano/Doctorado Nacional/2021-21210677 (SA-R)”.

In the published article, there was an error, in the reagent’s name used for Glutamine Synthetase assay; we wrote “hydroxyamide” where we meant “hydroxylamine”.

A correction has been made to Materials and methods, 2.7 Measurements of Glutamine Synthetase (GS) and Glutamate Dehydrogenase (GDH) activities, paragraph 1. This sentence previously stated:

“The mixture for the GS essay contained 500 µL of reaction buffer (80 mM glutamic acid, 20 mm MgSO₄, 8 mM ATP, 6 mM hydroxyamide, 1 mM ethylenediaminetetraacetic acid, 0.1 mM Tricine, pH 7.8).”

The corrected sentence appears below:

“The mixture for the GS essay contained 500 µL of reaction buffer (80 mM glutamic acid, 20 mm MgSO₄, 8 mM ATP, 6 mM hydroxylamine, 1 mM ethylenediaminetetraacetic acid, 0.1 mM Tricine, pH 7.8).”

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.

In the published article, there was an error in the Conflict of Interest statement. A correction has been made to the Conflict of Interest statement:

“The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

The handling editor [NFS] is currently organizing a Research Topic with the author [LBG].”

The Field Chief Editor Dr. Chun-Ming Liu has assessed the original manuscript, the correction, and the review process, and certifies the integrity of the review process.
