While many genes up-regulated by auxin have been characterized, less is known about the genes that are down-regulated by auxin. We isolated and characterized an auxin-repressed gene (RpARP) from the tree legume, Robinia pseudoacacia L. A sequence similarity search in public databases showed that the RpARP gene has homologs in various higher plants including monocots and dicots. The deduced amino acid sequences are highly conserved among these homologs (up to 85% identity). Northern blot analysis showed that auxin repressed RpARP gene expression and that repression was dependent on the presence of metabolizable sugar and on protein synthesis. In addition, cold treatment abolished the auxin-mediated repression of RpARP gene expression. Results from transgenic plant analyses suggest that RpARP gene expression is posttranscriptionally regulated by auxin and by the untranslated regions. Sequence analysis of the promoter region (-70 and -500 bp upstream of the putative transcription initiation site) of the RpARP gene identified four sucrose-repressible response elements (TATCCAT-motifs; Huang et al. 1990), suggesting that the cis-elements responsible for regulation by sucrose are located in the promoter region. In fact, the expression of the transgenic RpARP gene was unaffected by sucrose when driven by a CaMV 35S promoter.

Don is one of the most abundant species in the north of Spain. Knowledge of drought response mechanisms is essential to guarantee plantation survival under reduced water supply as predicted in the future. Tolerance mechanisms are being studied in breeding programs, because information on such mechanisms can be used for genotype selection. In this paper, we analyze the changes of leaf water potential, hydraulic conductance (K(leaf)), stomatal conductance and phytohormones under drought in P. radiata breeds (O1, O2, O3, O4, O5 and O6) from different climatology areas, hypothesizing that they could show variable drought tolerance. As a primary signal, drought decreased cytokinin (zeatin and zeatin riboside-Z\u2009+\u2009ZR) levels in needles parallel to K(leaf) and gas exchange. When Z\u2009+\u2009ZR decreased by 65%, indole-3-acetic acid (IAA) and abscisic acid (ABA) accumulation started as a second signal and increments were higher for IAA than for ABA. When plants decreased by 80%, Z\u2009+\u2009ZR and K(leaf) doubled their ABA and IAA levels, the photosystem II yield decreased and the electrolyte leakage increased. At the end of the drought period, less tolerant breeds increased IAA over 10-fold compared with controls. External damage also induced jasmonic acid accumulation in all breeds except in O5 (P. radiata var. radiata\u2009\u00d7\u2009var. cedrosensis), which accumulated salicylic acid as a defense mechanism. After rewatering, only the most tolerant plants recovered their K(leaf,) perhaps due to an IAA decrease and 1-aminocyclopropane-1-carboxylic acid maintenance. From all phytohormones, IAA was the most representative 'water deficit signal' in P. radiata.", "keywords": ["0301 basic medicine", "2.

White lupin is the only crop bearing CRs and is considered as the model species for CR studies. However, little information is available on CRs atypical development, including the molecular events that trigger their formation. To provide insights on CR formation, we performed an anatomical and cellular description of rootlet development in white lupin. Starting with a classic histological approach, we described rootlet primordium development and defined eight developmental stages from rootlet initiation to their emergence. Due to the major role of hormones in the developmental program of root system, we next focussed on auxin\uffe2\uff80\uff90related mechanisms. We observed the establishment of an auxin maximum through rootlet development in transgenic roots expressing the DR5:GUS auxin reporter. Expression analysis of the main auxin\uffe2\uff80\uff90related genes [TIR, Auxin Response Factor (ARF) and AUX/IAA] during a detailed time course revealed specific expression associated with the formation of the rootlet primordium. We showed that L. albus TRANSPORT INHIBITOR RESPONSE 1b is expressed during rootlet primordium formation and that L. albus AUXIN RESPONSE FACTOR 5 is expressed in the vasculature but absent in the primordium itself.

Auxin signaling regulates LR formation, but the molecular mechanism by which salinity affects root auxin signaling and whether salt induces other pathways that regulate LR development remains unknown. In Arabidopsis thaliana, the auxin-regulated transcription factor LATERAL ORGAN BOUNDARY DOMAIN 16 (LBD16) is an essential player in LR development under control conditions. Here, we show that under high-salt conditions, an alternative pathway regulates LBD16 expression. Salt represses auxin signaling but, in parallel, activates ZINC FINGER OF ARABIDOPSIS THALIANA 6 (ZAT6), a transcriptional activator of LBD16. ZAT6 activates LBD16 expression, thus contributing to downstream cell wall remodeling and promoting LR development under high-salt conditions. Our study thus shows that the integration of auxin-dependent repressive and salt-activated auxin-independent pathways converging on LBD16 modulates root branching under high-salt conditions.</p", "keywords": ["0301 basic medicine", "Salinity", "0303 health sciences", "03 medical and health sciences", "Indoleacetic Acids", "Arabidopsis Proteins", "Gene Expression Regulation", " Plant", "Arabidopsis", "Life Science", "Plant Roots", "Research Article"]}, "links": [{"href": "https://doi.org/PMC10980347"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/The%20Plant%20Cell", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "PMC10980347", "name": "item", "description": "PMC10980347", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/PMC10980347"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2023-12-23T00:00:00Z"}}, {"id": "PMC6121082", "type": "Feature", "geometry": null, "properties": {"updated": "2026-05-25T16:28:03Z", "type": "Journal Article", "created": "2018-06-15", "title": "Out of Shape During Stress: A Key Role for Auxin", "description": "In most abiotic stress conditions, including salinity and water deficit, the developmental plasticity of the plant root is regulated by the phytohormone auxin.
