--- _id: '12878' abstract: - lang: eng text: Salicylic acid (SA) plays important roles in different aspects of plant development, including root growth, where auxin is also a major player by means of its asymmetric distribution. However, the mechanism underlying the effect of SA on the development of rice roots remains poorly understood. Here, we show that SA inhibits rice root growth by interfering with auxin transport associated with the OsPIN3t- and clathrin-mediated gene regulatory network (GRN). SA inhibits root growth as well as Brefeldin A-sensitive trafficking through a non-canonical SA signaling mechanism. Transcriptome analysis of rice seedlings treated with SA revealed that the OsPIN3t auxin transporter is at the center of a GRN involving the coat protein clathrin. The root growth and endocytic trafficking in both the pin3t and clathrin heavy chain mutants were SA insensitivity. SA inhibitory effect on the endocytosis of OsPIN3t was dependent on clathrin; however, the root growth and endocytic trafficking mediated by tyrphostin A23 (TyrA23) were independent of the pin3t mutant under SA treatment. These data reveal that SA affects rice root growth through the convergence of transcriptional and non-SA signaling mechanisms involving OsPIN3t-mediated auxin transport and clathrin-mediated trafficking as key components. acknowledgement: The authors thank Professor Jianqiang Wu (Kunming Institute of Botany, Chinese Academy of Sciences) for support with phytohormone measurement.

Asymmetric\r\ndistribution of the phytohormone auxin is a necessary prerequisite to the tropic bending both in roots and\r\nshoots. During hypocotyl gravitropic response, the PIN3 auxin transporter polarizes within gravity-sensing\r\ncells to redirect intercellular auxin fluxes. First gravity-induced PIN3 polarization to the bottom cell mem-\r\nbranes leads to the auxin accumulation at the lower side of the organ, initiating bending and, later, auxin\r\nfeedback-mediated repolarization restores symmetric auxin distribution to terminate bending. Here, we per-\r\nformed a forward genetic screen to identify regulators of both PIN3 polarization events during gravitropic\r\nresponse. We searched for mutants with defective PIN3 polarizations based on easy-to-score morphological\r\noutputs of decreased or increased gravity-induced hypocotyl bending. We identified the number of\r\nhypocotyl reduced bending (hrb) and hypocotyl hyperbending (hhb) mutants, revealing that reduced bending corre-\r\nlated typically with defective gravity-induced PIN3 relocation whereas all analyzed hhb mutants showed\r\ndefects in the second, auxin-mediated PIN3 relocation. Next-generation sequencing-aided mutation map-\r\nping identified several candidate genes, including SCARECROW and ACTIN2, revealing roles of endodermis\r\nspecification and actin cytoskeleton in the respective gravity- and auxin-induced PIN polarization events.\r\nThe hypocotyl gravitropism screen thus promises to provide novel insights into mechanisms underlying cell\r\npolarity and plant adaptive development." article_processing_charge: Yes (via OA deal) article_type: original author: - first_name: Hana full_name: Rakusová, Hana last_name: Rakusová - first_name: Huibin full_name: Han, Huibin id: 31435098-F248-11E8-B48F-1D18A9856A87 last_name: Han - first_name: Petr full_name: Valošek, Petr id: 3CDB6F94-F248-11E8-B48F-1D18A9856A87 last_name: Valošek - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Rakusová H, Han H, Valošek P, Friml J.
