The authors of the above article request the correction of Figures 3A, 3D, 3F and 3G, Figure 4B, Figure 5B, Figure 6B, Figure 7A, Figure 8B, and Supplemental Figure 10B, as described below. The original results and conclusions are unaffected by these corrections. The authors apologize for any inconvenience caused to the readers. All authors have approved this correction.
In order to obtain fruits at the same developmental stage for length quantification, some of the fruits were imaged separately with a ruler and the images merged together during manuscript preparation. We corrected Figures 3A, 3D, 3F and 3G, Figure 4B, and Figure 7A by adding white lines between the separate images (corrected panels boxed in red for Figures 3, 4, and 5; corrected panel only shown for Figure 7). The figure legends and remaining figure panels are unchanged from the original version.
In the original Figure 5B, the same cucumber fruit was unintentionally imaged twice with different scales and mistakenly saved as different names (V/C and A-RNAi-6) during image processing. The corrected Figure 5B shows representative fruits of V/C and A-RNAi-6 transgenic lines; the replaced images are underlined in red. The figure legend and remaining figure panels are the same as the original version.

Protein Interactions Detected with Y2H and BiFC.
(B) Y2H assays showed CsFUL1A interacts with seven proteins including CsAGL20, while CsFUL1C does not interact with CsAGL20. No interactions were detected between CsFUL1A and CsFUL1C, CsFUL2, CsALC, or CsHEC3. No homodimer or heterodimer formed between CsFUL1A and CsFUL1C.
Y1H assay. (Supports Figure 7).
(B) The CsFUL1 A allele and CsFUL1 C allele bound to promoter fragments of CsPIN1 and CsPIN7 containing the CArG-box, but not to CsPID and CsARF12. CsCUM10 could not bind to these CArG-boxes.

Source data for Figure 6 and Supplemental Figure 10.
In the original Figure 6B and Supplemental Figure 10B, colony copy and paste errors occurred in the Y1H experiment, including that the two yeast colonies on the first row of Figure 6B were duplicates, and that control yeast images of CsFUL1A/P11 and CsFUL1A/P13 were repeatedly used three and two times, respectively, in Supplemental Figure 10B. We carefully checked the original yeast plate picture (shown with red circled colonies in images marked Source data) and corrected these two figures accordingly. The figure legend and remaining figure panels are unaltered from the original version. The replaced images in the corrected figures are underlined in red.
The same image processing mistake occurred in the top six rows of Figure 8B, including that yeast pictures of CsFUL1A-AD/BD were repeatedly used three times in the first two rows, and that colony images of CsFUL1A-BD/CsSEP2-AD and CsFUL1A-BD/CsSEP4-AD were repeated twice in rows 3-6. We traced back to the original yeast plate picture (shown with red circled colonies) and corrected Figure 8B accordingly. The figure legend and the rest of the figure panels are unaltered from the original version.
