AGRICULTURAL SCIENCES Correction for “Overexpression of a pH-sensitive nitrate transporter in rice increases crop yields,” by Xiaorong Fan, Zhong Tang, Yawen Tan, Yong Zhang, Bingbing Luo, Meng Yang, Xingming Lian, Qirong Shen, Anthony John Miller, and Guohua Xu, which was first published June 6, 2016; 10.1073/pnas.1525184113 (Proc Natl Acad Sci USA 113:7118–7123).
The authors note that on page 7121, left column, second full paragraph, line 7, “OsNRT2.3b-” should instead appear as “OsNRT2.3a-.”
The authors also note that Fig. 3 appeared incorrectly. The corrected figure and its legend appear below.
Fig. 3.
Growth, yield, and NUE of OsNRT2.3b, OsNRT2.3a, and H167R mutation overexpressing lines. (A) Phenotypes and transcriptional and translational expression of OsNRT2.3b- and OsNRT2.3a-overexpressing lines and Nipponbare WT. (B) Phenotypes and transcriptional and translational expression of WT and OsNRT2.3b-H167R mutant-overexpressing lines. (C) Average grain yield and NUE of OsNRT2.3b- (O), OsNRT2.3a- (a-O), and H167R- (H167R) overexpressing lines and WT in field plots. RT-PCR with the specific primers (SI Appendix, Table S10) and Western blot analyses with monoclonal antibodies were performed to identify protein expression levels. NUE = grain yield/applied N fertilizer. Values are mean ± SE (n = 3). a and b above bars indicate significant differences (P < 0.05) between the transgenic lines and WT estimated by one-way ANOVA.
