Error in Figure
In the original publication [1], an error was identified in Figure 7, affecting panels D–I. The updated Figure 7 includes replacement microscopic images for panels D–I that correspond to the appropriate treatment conditions used in this study. This correction does not affect the figure legend, the manuscript text, or the interpretation of the results. The scientific conclusions of the study remain unchanged.
In addition, the Acknowledgments Section has been updated to thank Dr. Ana Angelova and Xuechen Zhang for their support during the recombination experiments.
The corrected Figure 7 appears below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
