The LAVA mutants defective in auxin-regulated primary or lateral root development.
<p><span>Regulation of PIN activity, polarity as well as auxin gradient generation and its canalisation remain crucial topics in plant developmental biology especially in the context of organogenesis like the formation new lateral roots. Here, we are presenting the LAVA (LR Alterations Visualised after Auxin) collection of 278 mutants, defective in auxin-induced lateral root (LR) morphogenesis. Those mutants were obtained from a forward genetic screen in which synthetic auxin 1-Naphtyl Acetic Acid (1-NAA) was used to induce LR formation in the mutagenized PIN3::PIN3-GFP population. Our database contains mutant root phenotyping and for a subset of the collection, we recorded PIN polarity and subcellular trafficking, cotyledon vasculature development, primary and LR gravitropism as well as aerial phenotypes with some reminiscent to auxin-regulated organogenesis aberrations. We are convinced that our dataset can serve as a unique tool to identify novel components of auxin signalling, transport, and cell polarity but also be of interest to the broader plant research community interested in the roots system architecture that is vital for plant survival, growth and adaptation to environmental conditions.</span></p> <p><span>The phenotype analysis of the mutant collection is summarized and organised in an Excel spreadsheet (2024-08-07_mutant_database_Table S1). The photographic material is organised in folder form (see Supporting Data S1 in this repository), where each folder number corresponds to a particular mutant and entry in the excel table.</span></p> <p><span> Mutant seeds will be available in the European Arabidopsis Stock Centre (NASC). The seed sending to the repository is in progress. </span></p> <p><span>The manuscript describing this work is currently being submitted to the research journal.

Lateral Root Development in Two Tomato Accessions under Salt Stress
<p>The images of growing tomato seedlings were collected using SPIRO setup by Maryam Rahmati-Ishka every 30 minutes. However, as our automated script did not work for quantifying the lateral roots, Magda Julkowska traced the roots manually - for images collected every 60 minutes. </p> <p>The data was collected over 4 experiments, for two tomato genotypes: M248 - S. pimpinellifolium - wild tomato - salt tolerant - maintains the LR emergence under salt stress; and LA1511 - S. lycopersicum - cultivated tomato - salt tolerant - maintains the LR elongation under salt stress. </p>

Extrusion of medial and lateral meniscus before and after posterior root detachment
<p>Despite contemporary surgical treatments of posterior meniscus root tears, there is a low rate of healing and an incidence of residual meniscus extrusion approaching 30%. Here, we characterized and compared the behavior of the medial and lateral meniscus in response to axial compression load and real-time dynamic motion using a cadaveric model. There were no differences in the amount of meniscus extrusion between the medial and lateral meniscus with a competent posterior root (0.338mm vs. 0.235mm; p-value = 0.181). However, posterior root detachment resulted in a consistently increased amount of meniscus extrusion for the medial meniscus compared to the lateral meniscus (2.233mm vs. 0.4705mm; p-value < 0.0001). Moreover, the medial and lateral menisci responded differently to the effects of knee flexion angle. Detachment of the posterior root of the medial meniscus resulted in an increase in extrusion at all angles of knee flexion, but was most pronounced (4.00mm ± 1.26mm) at 30-degrees of knee flexion. In contrast, the lateral meniscus only extruded (1.65mm ± 0.97mm) in full extension. Furthermore, only the medial meniscus extruded during dynamic flexion after posterior root detachment. These findings suggest that while meniscus extrusion occurs in both the medial and lateral meniscus, the functional consequences of extrusion are more significant for the medial meniscus than that of the lateral meniscus. Limiting the amount of meniscus extrusion after posterior root tear in response to static compressive forces and dynamic motion is necessary to recapitulate native meniscus function.</p>

Data from: Nod factors potentiate auxin signaling for transcriptional regulation and lateral root formation in Medicago truncatula
Nodulation (Nod) factors (NFs) are symbiotic molecules produced by rhizobia that are essential for establishment of the rhizobium–legume endosymbiosis. Purified NFs can stimulate lateral root formation (LRF) in Medicago truncatula, but little is known about the molecular mechanisms involved. Using a combination of reporter constructs, pharmacological and genetic approaches, we show that NFs act on early steps of LRF in M. truncatula, independently of the ethylene signaling pathway and of the cytokinin receptor MtCRE1, but in interaction with auxin. We conducted a whole-genome transcriptomic study upon NF and/or auxin treatments, using a lateral root inducible system adapted for M. truncatula. This revealed a large overlap between NF and auxin signaling and, more interestingly, synergistic interactions between these molecules. Three groups showing interaction effects were defined: group 1 contained more than 1500 genes responding specifically to the combinatorial treatment of NFs and auxin; group 2 comprised auxin-regulated genes whose expression was enhanced or antagonized by NFs; and in group 3 the expression of NF regulated genes was antagonized by auxin. Groups 1 and 2 were enriched in signaling and metabolic functions, which highlights important crosstalk between NF and auxin signaling for both developmental and symbiotic processes.
