Abstract Soil stresses impact crop yields, presenting global agricultural challenges. compaction triggers root length reduction and radial expansion driven by the plant hormone ethylene. We report how ethylene controls cell wall properties to promote expansion. demonstrate soil stress, via ethylene, upregulates Auxin Response Factor1 in cortex, which represses Cellulose Synthase ( CESA ) genes. repression drives of cortical cells modifying thickness mechanics their walls, result a “stiff...
Abstract During tissue development and regeneration, cells interpret exert mechanical forces that are challenging to measure in vivo. Therefore, stress inference algorithms have emerged as powerful tools estimate stresses. However, how incorporate dynamics effectively into the remains elusive. Here, we present ForSys, a Python-based software estimates intercellular stresses intracellular pressures using time-lapse microscopy. We validated ForSys silico vivo well-characterized mucociliary...
ABSTRACT Collective cell rotations are widely used during animal organogenesis. Theoretical and in vitro studies have conceptualized rotating cells as identical rigid-point objects that stochastically break symmetry to move monotonously perpetually within an inert environment. However, it is unclear whether this notion can be extrapolated a natural context, where ephemeral heterogeneous cellular cohorts interact with active epithelium. In zebrafish neuromasts, nascent sibling hair invert...
Abstract Biological systems are never at equilibrium but maintain stability despite perennial external disturbance. A prime example is organ regeneration, whereby intrinsically stochastic damage, organs rebuilt via controlled cellular proliferation. Here, we use a mathematical approach to understand how cell decides re-enter and exit mitosis during repair. Using empirical data from regenerating neuromasts in larval zebrafish, identify minimal model based on ordinary differential equations...
Amazonia is well known for its high natural regeneration capacity; this reason, passive restoration normally recommended the recovery of degraded forests. However, highly deforested landscapes in southern require active restoration. Since methods can shape quality and speed early forest recovery, study aimed to verify how pushes sites stably covered with exotic grasses towards recovery. We evaluated succession at sites, i.e., soil plowing, direct seeding pioneer species, seedling stock...
Abstract Background: Amazonia is well known for its high natural regeneration capacity; this reason, passive restoration normally recommended the recovery of degraded forests. However, highly deforested landscapes in southern require active restoration. Since methods can shape quality and speed early forest recovery, study aimed to verify how pushes non-resilient sites towards recovery. Methods: We evaluated succession at sites, i.e. soil plowing, direct seeding pioneer species seedling...
The reaction-diffusion model constitutes one of the most influential mathematical models to study distribution morphogens in tissues. Despite its widespread use, effect finite tissue size on model-predicted spatio-temporal morphogen distributions has not been completely elucidated. In this study, we analytically investigated predicted by a one-dimensional domain, as proxy for biological tissue, and compared it with solution infinite-domain model. We explored reduced parameter, length units...
Transport of cellular cargo by molecular motors requires directionality to ensure proper biological functioning. During sporulation in Bacillus subtilis, chromosome transport is mediated the interaction between membrane-bound DNA translocase SpoIIIE and specific octameric sequences (SRS). Whether SRS regulate recruiting orienting or simply catalyzing its translocation activity still unclear. By using atomic force microscopy single-round fast kinetics assays we determined localization...

Abstract The reaction-diffusion model constitutes one of the most influential mathematical models to study distribution morphogens in tissues. Despite its widespread use, effect finite tissue size on model-predicted spatiotemporal morphogen distributions has not been completely elucidated. In this study, we analytically investigated predicted by a 1D domain, as proxy for biological tissue, and compared it with solution infinite-domain model. We explored reduced parameter, length units...

Mutations in the transcriptional co-activator Eya1 cause branchio-oto-renal syndrome (BOR) humans. BOR has an incidence of 1/40,000 and is characterized by congenital branchial fistulas, malformations inner ear kidney hypoplasia.

Mutations in the transcriptional co-activator Eya1 cause branchio-oto-renal syndrome (BOR) humans and equivalent condition vertebrates. BOR is characterized by congenital branchial fistulas, malformations of inner ear kidney hypoplasia. Here we use mechanosensory lateral line zebrafish to better understand role organogenesis.
