C., Smulevich, G., et al. (2020). Front. Plant Sci. 11:600336. doi: 10.3389/fpls.2020.600336 In the original article, there were three errors. The concentrations of antibiotics should be expressed in micrograms per milliliter; the pH of the Tris buffer should be 8.0; and the concentration of deoxyferrous globin should be stated as 2.5 micromolar. Two corrections have been made to: MATERIALS AND METHODS, Production and Purification of Recombinant Globins, paragraph 1, line 7 and line 17, “...of LB medium with 100 µg ml−1ampicillin or 100 µg ml−1kanamycin,...” “..20 mM Tris (pH 8.0) with 150 mM NaCl...” One correction has been made to: MATERIALS AND METHODS, Nitrite Reductase Activity, paragraph 1, line 4, “...were 2.5 µM and 0.05–1 mM, respectively.” 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. Copyright © 2021 Villar, Larrainzar, Milazzo, Pérez-Rontomé, Rubio, Smulevich, Martínez, Wilson, Reeder, Huertas, Abbruzzetti, Udvardi and Becana.
