Cai W., Ma J., Chi W., Zou M., Guo J., Lu C, and Zhang L. Cooperation of LPA3 and LPA2 Is Essential for Photosystem II Assembly in Arabidopsis.
The authors of the above article are retracting it from Plant Physiology following an investigation into concerns of the origin and assembly of several figures. In Figure 2D, lanes labeled 1 and 0.5 of the wild type were duplicated. In Figure 4D, the “cloned” backgrounds were improperly used for the original images in three YFP panels (Alb3-NY+LPA1-CY, LPA1-NY+LPA3-CY, and LPA1-NY+LPA2-CY). In addition, two YFP/chlorophyll signals that were not in one field of vision in the LPA2-NY+LPA3-CY series of images were combined into the same frame. The characterizations of the lpa3 mutants have been repeated, and the results were reproduced in the authors’ laboratory. They are therefore confident that the conclusions of this article remain valid, namely that LPA3 is involved in PSII assembly, but are retracting the article because of the irregularities and inappropriate data handling. They apologize for the publication of this erroneous paper and deeply regret the inconvenience caused.
