Abstract Plants undergo extended morphogenesis. The shoot apical meristem (SAM) allows for reiterative development and the formation of new structures throughout life plant. Intriguingly, SAM produces morphologically different leaves in an age-dependent manner, a phenomenon known as heteroblasty. In Arabidopsis thaliana, small orbicular juvenile phase, but gives rise to large elliptical adult phase. Previous studies have established that developmental decline microRNA156 (miR156) is necessary sufficient trigger this leaf shape switch, although underlying mechanism poorly understood. Here we show gradual increase miR156-targeted SQUAMOSA PROMOTER BINDING PROTEIN-LIKE transcription factors with age promotes cell growth anisotropy abaxial epidermis at base blade, evident by elongated giant cells. Time-lapse imaging genetics further revealed establishment tightly associated longitudinal expansion cells, accompanied prolonged proliferation phase their vicinity. Our results thus provide plausible cellular heteroblasty Arabidopsis, contribute our understanding anisotropic plants.

Abstract Quantitative plant biology is an interdisciplinary field that builds on a long history of biomathematics and biophysics. Today, thanks to high spatiotemporal resolution tools computational modelling, it sets new standard in science. Acquired data, whether molecular, geometric or mechanical, are quantified, statistically assessed integrated at multiple scales across fields. They feed testable predictions that, turn, guide further experimental tests. features such as variability, noise, robustness, delays feedback loops included account for the inner dynamics plants their interactions with environment. Here, we present main this ongoing revolution, through questions around signalling networks, tissue topology, shape plasticity, biomechanics, bioenergetics, ecology engineering. In end, quantitative allows us question better understand our plants. opens door transdisciplinary projects society, notably citizen

At the center of cell biology is our ability to image and its various components, either in isolation or within an organism. Given importance, biological imaging has emerged as a field own, which inherently highly interdisciplinary.

Live collectively involves all techniques aimed at live samples. It rapidly evolving field, with countless dyes being continuously developed. Some these methods reagents are readily amenable plant samples, while others not require specific modifications field. Here, we review some recent advances cells. In particular, discuss solutions that use membrane-bound organelles, cytoskeleton hormones, mechanical properties cells tissues. We only consider per se, but also how construction fluorescent probes pipelines driving biology.

Plants produce a rich diversity of biological forms, and the leaves is especially notable. Mechanisms leaf morphogenesis have been studied in past two decades, with growing focus on interactive roles mechanics recent years. Growth plant organs involves feedback by mechanical stress: growth induces stress, stress affects morphogenesis. Although much attention has given to potential stress-sensing mechanisms cellular responses, principles guiding not well understood. Here we synthesize overarching multilevel multiple stages morphogenesis, encompassing primordium initiation, phyllotaxis venation patterning, establishment complex mature shapes. Moreover, at multiscale levels, from subcellular cytoskeletal molecules single cells tissues organ scale, are articulated.

Abstract The establishment of a functioning neuronal network is crucial step in neural development. During this process, neurons extend neurites—axons and dendrites—to meet other interconnect. Therefore, these neurites need to migrate, grow, branch find the correct path their target by processing sensory cues from environment. These processes rely on many coupled biophysical effects including elasticity, viscosity, growth, active forces, chemical signaling, adhesion cellular transport. Mathematical models offer direct way test hypotheses understand underlying mechanisms responsible for neuron Here, we critically review main neurite growth morphogenesis mathematical viewpoint. We present different guidance morphogenesis, with particular emphasis mechanics mechanisms, simple that can be partially treated analytically.

Abstract Tomato (Solanum lycopersicum) fruit shape is related to microtubule organization and the activity of microtubule-associated proteins (MAPs). However, insights into mechanism formation from a cell biology perspective remain limited. Analysis tissue expression profiles different regulators revealed that functionally distinct classes MAPs, including members plant-specific MICROTUBULE-ASSOCIATED PROTEIN 70 (MAP70) IQ67 DOMAIN (IQD, also named SUN in tomato) families, are differentially expressed during development. SlMAP70-1–3 SlIQD21a highly initiation, which relates dramatic pattern rearrangements throughout this developmental stage tomato fruits. Transgenic lines overexpressing SlMAP70-1 or produced elongated fruits with reduced circularity anisotropy, while their loss-of-function mutants showed opposite phenotype, harboring flatter Fruits were further plants coexpressing both SlIQD21a. We demonstrated SlMAP70s physically interact phenotype likely due stabilization induced by SlMAP70–SlIQD21a interaction. Together, our results identify SlMAP70 as important elongation demonstrate manipulating function early development provides an effective approach alter shape.
