The above article, published online on 30 July 2025 in Wiley Online Library (wileyonlinelibrary.com), and its erratum (https://doi.org/10.1002/ijc.33194), have been retracted by agreement between the journal Editor-in-Chief, Christoph Plass; the Union for International Cancer Control; and John Wiley & Sons Ltd. A third party reported on PubPeer [1] that images in Figure 3 were later published in another article by different authors [Jiang et al. 2018 (https://doi.org/10.1111/jcmm.13732)] and that Figure 1c(2) was also published in a separate article by different authors [Wu et al. 2018 (https://doi.org/10.7150/jca.26359)]. Further investigation by the publisher found that several lanes of the GAPDH bands in Figure 4a had been re-used and labeled as beta-actin in another article by some of the same authors [Li et al. 2018 (https://doi.org/10.7150/ijbs.24505)] and that there was evidence of duplication and splicing in Figures 2a and 3a. Additionally review by the editors found concerns about data handling that were not adequately addressed during peer review. Additionally, upon re-investigation, the authors' previous explanation for the erratum which replaced images in Figures 2d, 2g, and 2h was not considered satisfactory by either the editors or the publisher. The authors did not respond to an inquiry by the publisher. The retraction has been agreed to because the concerns over data handling, coupled with evidence that the authors have re-used data in a later article, fundamentally compromises the editors' confidence in the results in this article. The authors were informed of the retraction. REFERENCE: [1] Reese Richardson.

Although Rho of Plants GTPases play well-established roles in regulating development and stress signalling, their functions in plant adaptation to waterlogging stress has yet to be fully elucidated. Here, we identified nine CsROP genes in the cucumber genome, which exhibit evolutionary diversification but retain conserved functional domains. Functional analysis revealed that CsROP2 acts as a negative regulator of adventitious root formation. It modulates auxin accumulation in hypocotyl vascular bundles, thereby suppressing adventitious root development and enhancing waterlogging sensitivity. The HD-Zip I transcription factor CsTBH directly binds the CsROP2 promoter and activates its expression. Our study uncovers a CsTBH-CsROP2 module that governs adventitious rooting and waterlogging tolerance by modulating auxin homeostasis.

To explore the regulatory function of JAZ genes in this disease resistance system, this study focused on SlJAZ3 and found that both SlJAZ3 and its interacting protein SlJAZ2 can positively regulate the resistance response mediated by Cf-19. In addition, SlMYC2, as a positive regulator of the resistance response, can interact with SlJAZ2 (or SlJAZ3) and activate the expression of SlPR2. Notably, SlJAZ3 (or SlJAZ2) competitively binds to SlJAZ2 (or SlJAZ3), reducing its binding to SlMYC2, which helps to restore the transcriptional activation of the downstream defense gene SlPR2. Our findings reveal that the SlJAZ2/SlJAZ3 dimer regulates downstream signal transduction.
