Morphogenesis emerges from complex multiscale interactions between genetic and mechanical processes. To understand these processes, the evolution of cell shape, proliferation gene expression must be quantified. This quantification is usually performed either in full 3D, which computationally expensive technically challenging, or on 2D planar projections, introduces geometrical artifacts highly curved organs. Here we present MorphoGraphX (www.MorphoGraphX.org), a software that bridges this...
This study examines historical water management practices as a means of addressing climate change, focusing on the Tyski Stream catchment in Upper Silesia, Poland, region marked by extensive urbanization and industrial evolution. It investigates effectiveness hydrotechnical systems, such bead-like ponds from 15th to 18th centuries, enhancing retention, reducing flood risks, supporting ecosystem services. In critical period, over 54 years (1827–1881), number reservoirs decreased 142 31 (the...
Premise of the Study In numerous vascular plants, pavement cells leaf epidermis are shaped like a jigsaw‐puzzle piece. Knowledge about subcellular pattern growth that accompanies morphogenesis such complex shape is crucial for studies role cytoskeleton, cell wall and phytohormones in plant development. Because detailed anticlinal periclinal walls remains unknown, our aim was to measure at resolution. Methods Using fluorescent microbeads applied surface adaxial Arabidopsis thaliana as...
The relatively thick primary walls of epidermal and collenchyma cells often form waviness on the surface that faces protoplast when they are released from tensile in-plane stress operates in situ. This is a manifestation buckling results heterogeneity elastic strain across wall. In this study, was confirmed by spontaneous bending isolated wall fragments were initially flat. We combined empirical data formation growing cell with computations buckled shapes. chose cylindrical-shaped organs...
For modeling the magnetic properties of concentrated and diluted semiconductors, we use Kondo-lattice model. The phase diagram is derived by inspecting static susceptibility itinerant band electrons, which are exchange coupled to localized moments. It turns out that rather low occupations favor a ferromagnetic ordering local moment systems due an indirect coupling mediated spin polarization charge carriers. disorder in treated adding CPA-type concept theory. almost all concentrations $x$,...
Growth and cellular organization of the Arabidopsis root apex are investigated in various aspects, but still little is known about spatial directional variation growth rates very apical part apex, especially 3D. The present paper aims to fill this gap with aid a computer modelling based on tensor method. typical shape pattern considered. Previously, basis two types empirical data: published velocity profile along axis dimensions cell packets formed lateral cap, displacement field for was...
Pollen tubes are extremely rapidly growing plant cells whose morphogenesis is determined by spatial gradients in the biochemical composition of cell wall. We investigate hypothesis (MP) that distribution local mechanical properties wall, corresponding to change radial symmetry along axial direction, may lead growth oscillations pollen tubes. claim experimentally observed originate from at transition zone, where both intervening symmetries (cylindrical and spherical) meet. The characteristic...
In angiosperms, growth of the root apex is determined by quiescent centre. All tissues proper and cap are derived from initial cells that surround this zone. The diversity cell lineages originated these initials suggests an interesting variation displacement velocity within apex. However, little known about variation, especially in most apical region including cap. This paper shows a method determination field for taking Arabidopsis as example. Assuming symplastic without rotation around...
The development of cell pattern in the surface layer shoot apex can be investigated vivo by use a time-lapse confocal images, showing naked meristem 3D successive times. However, how this is originated from apical initials and develops as result growth divisions their descendants, remains unknown. This an open area for computer modelling. A method to generate presented on example paraboloidal dome. In used model originates three that meet at dome summit through under isotropic growth,...
There are two families of lines describing the cell wall pattern in root and shoot apices; periclines anticlines. The these mutually orthogonal steady during apex growth. They approximate orientation walls apices. These preserved growing organ. direction anticlines is regulated at organ level. This paper focuses on question: how maintained? a number rules, which deal with problem new wall. We test three them: Errera rule (the smallest possible area that divides mother into equal portions...

We considered a system of microtubule(s) (MTs) immersed in water reservoir order to investigate its thermodynamic properties and computation (processing) potential. started with the “double frustration” concept for single microtubule next extended our considerations an MT multi-cluster. probed influence physical anomalies compressibility speed sound, where acoustic phonons that are conjugated stress fluctuations produced by changes symmetry, possible carriers information cause ‘calculation’...
The topology of a cellular pattern, which means the spatial arrangement cells, directly corresponds with cell packing, is crucial for tissue and organ functioning. topological features cells that are typically analyzed number their neighbors area. To date, objects most studies have been growing surface tissues plant animal organs. Some these researches also provide verification Lewis's Law concerning linear correlation between neighboring Our aim was to analyze applicability an...
The hitherto unexplained presence of 12 or 13 tubulin dimmers forming parallel protofilament subunits in microtubules (MTs) is supposed to ensure sum checking the system two MTs, each one being a potential computing ‘core’. recently proposed, frustration – originated, double well mapped, exclusively for modelling reasons, onto Ising type Hamiltonian acting rings with an intra-site nearest neighbours interaction. We infer that final state energetically favourable qubit ‘calculation’ at...
Microscopic observations of lateral roots (LRs) in Arabidopsis thaliana reveal that the cross-sectional shape organ changes from its basal to apical region. The founder cells for LRs are elongated along parent root axis, and thus site initiation base resemble an ellipse. circumference part is usually a circle. objective this study was analyse characteristics growth eld possessing various shapes their regions. wild type (Col-0) two transgenic arabidopsis lines were analysed. On basis...
Abstract The model of the magnetic binary alloy which contains interacting itinerant electrons and localized spins was considered. interaction between both kinds assumed in simple local exchange form. complicated many body problem reduced to one particle with help Coherent Potential Approximation ( CPA ). Itinerant electron selfenergy calculated using standard Green's function technique taking into account short range order SRO ) within spin system. Electron's states were strongly affected...
The phenomenon of persistent frustration pollen tubes led us to recognition a new form anharmonic potential, which after simple transformation may yield so called ‘double well potential’. Because possible links with conformational changes taking place in microtubules (MT) human brain neuronal system, start with, we have calculated the shift energy levels double potential respect infinite square well. We conjecture that dynamic instability MTs, has not been elucidated yet, be effect recently...
Abstract The problem of the origin canonical and aberrant DNA mutations contribution protons encoding to genetic stability is an essential topic in molecular biology. Based on empirical results, we reconsidered tautomeric under two-fluid model quantum physics. We assumed that proton-induced pressure environment could change concentration ratio between base pairs, which were found be different at beyond criticality level, respectively. anticipate deviation cellular system from a specific...
