Soh2020 - Spatio-temporal morphogen gradient and BMP signaling

ABSTRACT: This model couples BMP morphogen gradient formation with Smad signaling in zebrafish and reproduces Fig.3B of the referenced paper. mBMP4 diffuses and forms a morphogen gradient in the host tissue where differential signal transduction kinetics for pSmad2 versus pSmad5 lead to narrow (pSmad2) versus wide (pSmad5) signal activity ranges in response to the same morphogen gradient (mBMP4) as input. The model file is in MorpheusML format and can be opened in the free, open-source multicellular modeling software Morpheus (https://morpheus.gitlab.io) to simulate the time course (movie) of the spatio-temporal dynamics. Further optional plots of the radial solution profile and the time courses of mean concentrations over the domain are included and temporarily inactivated in the model file, in section Analysis.

Integration of Nodal and BMP Signaling by Mutual Signaling Effector Antagonism.

Soh Gary Huiming GH Pomreinke Autumn Penecilla AP Müller Patrick P

Cell reports 20200401 1

Opposing sources of bone morphogenetic protein (BMP) and Nodal signaling molecules are sufficient to induce the formation of a full axis in zebrafish embryos. To address how these signals orchestrate patterning, we transplant sources of fluorescently tagged Nodal and BMP into zebrafish embryos, robustly inducing the formation of secondary axes. Nodal and BMP signal non-cell-autonomously and form similar protein gradients in this context, but the signaling range of Nodal (pSmad2) is shorter than ...[more]

Vu2019 - Planarian tissue polarity

Project description:The model explores the establishment and stability of the wildtype polarity pattern in planarian flatworms. Initial conditions for A and M fields are chosen as arbitrarily perturbed to demonstrate stability of the wild type pattern. A represents the A/P polarization system, M represents the M/L polarization system and P represents the resulting superimposed and normalized polarization. P can be compared to the measured polarity data of ciliary rootlets. This simulation reproduces Figure 4C of the referenced paper. Parameter values correspond to the wild type pattern (control) as given in Table S2 of the referenced paper. The model file is in MorpheusML format and can be opened in the free, open-source multicellular modeling software Morpheus (https://morpheus.gitlab.io) to simulate the time course (movie) of the spatio-temporal dynamics.

Vu2019 - Planarian double-head regeneration

Project description:This spatio-temporal model explores tissue polarity re-organization during planarian double-head formation upon regeneration with beta-catenin-1 RNAi treatment. Initial conditions for A and M polarity fields are chosen near the wild type pattern and the first 100 time steps are used to establish the typical wild type splay pattern. The induction of the ectopic head occurs at time-step 100 (interpreted as tail amputation time) at the position where the former tail was (right end), subsequently affects the nearby tissue with some lag and then re-polarizes the posterior half of the tissue from time-step 200 onward. Of these polarity fields, A represents the anterior-posterior polarization system provided by the core PCP pathway, M represents the medio-lateral polarization system provided by the Ft/Ds pathway and P represents the resulting superimposed and normalized polarization. P can be compared to the observable polarity data of ciliary rootlets. This simulation reproduces Figure 4D of the referenced paper. Parameter values correspond to the beta-catenin-1(RNAi) pattern as given in Table S2 of the referenced paper. The model file is in MorpheusML format and can be opened in the free, open-source multicellular modeling software Morpheus (https://morpheus.gitlab.io) to simulate the time course (movie) of the spatio-temporal dynamics.

Miyazawa2010 - changing turing patterns by spatial parameter sweep

Project description:Biologists have long been fascinated by the amazing diversity of animal colour patterns. Despite much interest, the underlying evolutionary and developmental mechanisms contributing to their rich variety remain largely unknown, especially the vivid and complex colour patterns seen in vertebrates. The model [1] shows, that complex and camouflaged animal markings can be formed by the ‘blending’ of simple colour patterns. A mathematical model predicts that crossing between animals having inverted spot patterns (for example, ‘light spots on a dark background’ and ‘ dark spots on a light background’ ) will necessarily result in hybrid offspring that have camouflaged labyrinthine patterns as ‘ blended ’ intermediate phenotypes. In [1] the authors confirmed the broad applicability of the model prediction by empirical examination of natural and artificial hybrids of salmonid fish. The results suggest an unexplored evolutionary process by means of ‘pattern blending’, as one of the possible mechanisms underlying colour pattern diversity and hybrid speciation. The model file is in MorpheusML format and can be opened in the free, open-source multicellular modeling software Morpheus (https://morpheus.gitlab.io) to simulate the time course (movie) of the spatio-temporal dynamics. It resembles figure 3a from [1], where a 2D parameter space shows the transition from black to white spots through intermediate labyrinthine patterns. 1.

Mobile PEAR transcription factors integrate hormone and miRNA cues to prime cambial growth

Project description:In addition to apical growth, plants undergo radial growth to increase girth, a particularly prominent feature in trees. During both apical and radial growth the phytohormones auxin and cytokinins form symmetries that govern further growth patterns. But whereas the gene regulatory networks interpreting the hormonal fields during apical growth are well established, such networks are not known for the radial growth. We show here that the initiation of radial growth occurs around early protophloem sieve element (PSE) cell files of the root procambial tissue in Arabidopsis. In this domain cytokinin signalling promotes expression of a pair of novel mobile transcription factors, PHLOEM EARLY DOF (PEAR1, PEAR2) and their four homologs (OBP2, DOF6, TMO6 and HCA2), collectively called PEAR proteins. The PEAR proteins form a short-range concentration gradient peaking at PSE and activating gene expression that promotes radial growth. The expression and function of PEAR proteins are antagonized by well-established polarity transcription factors, HD-ZIP III, whose expression is concentrated in the more internal domain of radially non-dividing procambial cells by the function of auxin and mobile miR165/166. The PEAR proteins locally promote transcription of their inhibitory HD-ZIP III genes, thereby establishing a negative feedback loop that forms a sharp boundary demarking the zone of cell divisions. Taken together, we have established a network, in which the PEAR - HD-ZIP III module integrates the spatial information of the hormonal domains and miRNA gradients during root procambial development, to provide a pre-pattern with actively dividing and more quiescent zones, thus priming radial growth.

Identification of regulators of vascular proliferation

Project description:Vascular tissue transports water and nutrients throughout the plant body and is consequently essential for growth and development. In Arabidopsis, the vascular tissue is initiated at the centre of the embryo. During embryogenesis it is found in a characteristic diarch pattern with a central file of xylem cells with an adjacent layer of procambium on either side. Phloem poles are present on the outside of the procambium layers. Following germination a series of cell divisions results in the reorganisation of the vascular tissue which transitions to a radially symmetric structure. The RNA-seq data associated with this submission captures those early events. In 7-day old seedlings, wild type hypocotyl s have begun the process of change towards radial symmetry. In pxy mutants this process is stalled, and in 35S::CLE41 lines, radial expansion occurs prematurely. In root tissue of this age there is little evidence of the transition to radial symmetry in any of the genotypes tested. The RNA-seq dataset submitted will thus provide insight into the changes required to reorganise Arabidopsis vascular tissue as it transitions from primary to secondary growth.

Genome-Wide expression under osmotic stress conditions in Saccharomyces cerevisiae

Project description:Changes in RNA levels during osmotic stress were investigated. Total RNA was extracted from a wild-type yeast strain before and after treatment with 0.4 M NaCl and the corresponding cDNAs were hybridazed on Tiling arrays. In particular, for all the intron-containing genes, the changes in the levels of intron signal in stressed cells related to the intron signal in the non-stressed cells, and the changes in the levels of exon signal in stresses cells related to the exon signal in non-stressed cells were investigated. The supplementary bar file contains the ratios between stress signals respect to non-stress signals, using the average of the 3 biological replicas.
