It seems that you're in Germany. We have a dedicated site for Germany. The recent application of molecular genetics to problems of developmental biology has provided us with greater insight into the molecular mechanisms by which cells determine their developmental fate. This is particularly evident in the recent progress in understanding of developmental processes in model animal systems such as Drosophila melanogaster and Caenorhabditis elegans. The primary concentration is on descriptions rather than interpretations, as interpretations evolve and change relatively rapidly, whereas the evolution of plant form takes place on a much longer time scale.

Protocol DOI: Scanning Electron Microscopy SEM allows the morphological characterization of the surface features of floral and inflorescence structures in a manner that retains the topography or three-dimensional appearance of the structure. Even at relatively. Even at relatively low magnification levels it is possible to characterize early developmental stages. Using medium to high power magnification at later stages of development, cell surface morphology can be visualized allowing the identification of specific epidermal cell types.

Plant growth and development are regulated by a tightly controlled interplay between cell division, cell expansion and cell differentiation during the entire plant life cycle from seed germination to maturity and seed propagation. With this exploratory multi-omics dataset, development dynamics of photosynthetic tissues can be investigated from different angles. As expected, we found progressive global expression changes between growth stages for all three omics types and often but not always corresponding expression patterns for individual genes on transcript, protein and phosphorylation site level.

Arabidopsis: An Atlas of Morphology and Development

Agar is a mixture of two components: the linear polysaccharide agarose , and a heterogeneous mixture of smaller molecules called agaropectin. These algae are known as agarophytes , and belong to the Rhodophyta red algae phylum. Agar has been used as an ingredient in desserts throughout Asia, and also as a solid substrate to contain culture media for microbiological work. Agar can be used as a laxative , an appetite suppressant, a vegetarian substitute for gelatin , a thickener for soups , in fruit preserves , ice cream , and other desserts, as a clarifying agent in brewing , and for sizing paper and fabrics.

Arabidopsis: An Atlas of Morphology and Development

A fundamental question in biology is how morphogenesis integrates the multitude of processes that act at different scales, ranging from the molecular control of gene expression to cellular coordination in a tissue. Using machine-learning-based digital image analysis, we generated a three-dimensional atlas of ovule development in Arabidopsis thaliana , enabling the quantitative spatio-temporal analysis of cellular and gene expression patterns with cell and tissue resolution. We discovered novel morphological manifestations of ovule polarity, a new mode of cell layer formation, and previously unrecognized subepidermal cell populations that initiate ovule curvature. Our work demonstrates the analytical power of a three-dimensional digital representation when studying the morphogenesis of an organ of complex architecture that eventually consists of cells. How organs attain their species-specific size and shape in a reproducible manner is an important question in biology. Tissue morphogenesis constitutes a multi-scale process that occurs in three dimensions 3D. It necessitates the quantitative 3D analysis of cell size, cell shape, and cellular topology, an approach that has received much less attention Boutros et al.

This atlas documents the morphology and development of Arabidopsis thaliana, a small flowering plant which emerged during the s as a primary model for research in the field of plant biology. It covers embryogenesis, vegetative and root growth, reproduction and host-pathogen interaction.

Metrics details. The formation of flowers is one of the main model systems to elucidate the molecular mechanisms that control developmental processes in plants. Although several studies have explored gene expression during flower development in the model plant Arabidopsis thaliana on a genome-wide scale, a continuous series of expression data from the earliest floral stages until maturation has been lacking. Here, we used a floral induction system to close this information gap and to generate a reference dataset for stage-specific gene expression during flower formation.
