Control of Arabidopsis apical-basal embryo polarity by antagonistic transcription factors. [PDF]
, 2010 Plants, similarly to animals, form polarized axes during embryogenesis on which cell differentiation and organ patterning programs are orchestrated. During Arabidopsis embryogenesis, establishment of the shoot and root stem cell populations occurs at ...

The CLV-WUS Stem Cell Signaling Pathway: A Roadmap to Crop Yield Optimization
Plants, 2018 The shoot apical meristem at the growing shoot tip acts a stem cell reservoir that provides cells to generate the entire above-ground architecture of higher plants. Many agronomic plant yield traits such as tiller number, flower number, fruit number, and

Cadmium and arsenic affect root development in Oryza sativa L. negatively interacting with auxin [PDF]
, 2018 Cadmium (Cd) and arsenic (As), non essential, but toxic, elements for animals and plants are frequently present in paddy fields. Oryza sativa L., a staple food for at least the half of world population, easily absorbs As and Cd by the root, and in this ...

Response of meristem cells to hyperoxygenation
Biology of the Cell, 1990 Summary— Cycle parameters were estimated in Allium cepa L meristems proliferating under steady state conditions in tap water aerated with either 21 or 100% O2 and containing 7.9 and 39.0 mg/1 of dissolved oxygen, respectively. Cycle time was slightly but consistently reduced under hyperoxygenation, as shown in synchronous cells labelled as binucleate ...

Regulation of Plant Growth and Development: A Review From a Chromatin Remodeling Perspective
Frontiers in Plant Science, 2018 In eukaryotes, genetic material is packaged into a dynamic but stable nucleoprotein structure called chromatin. Post-translational modification of chromatin domains affects the expression of underlying genes and subsequently the identity of cells by ...

Semiparametric modeling of autonomous nonlinear dynamical systems with applications [PDF]
arXiv, 2009 In this paper, we propose a semi-parametric model for autonomous nonlinear dynamical systems and devise an estimation procedure for model fitting. This model incorporates subject-specific effects and can be viewed as a nonlinear semi-parametric mixed effects model. We also propose a computationally efficient model selection procedure.

Control of flower development in Arabidopsis thaliana by APETALA1 and interacting genes [PDF]
, 1993 Mutations in the APETALA1 gene disturb two phases of flower development, flower meristem specification and floral organ specification. These effects become manifest as a partial conversion of flowers into inflorescence shoots and a disruption of sepal ...

Cell-based model of the generation and maintenance of the shape and structure of the multi-layered shoot apical meristem of Arabidopsis thaliana [PDF]
arXiv, 2018 One of the central problems in animal and plant developmental biology is deciphering how chemical and mechanical signals interact within a tissue to produce organs of defined size, shape and function. Cell walls in plants impose a unique constraint on cell expansion since cells are under turgor pressure and do not move relative to one another.

Mutations in the PERIANTHIA gene of Arabidopsis specifically alter floral organ number and initiation pattern [PDF]
, 1996 An open question in developmental biology is how groups of dividing cells can generate specific numbers of segments or organs. We describe the phenotypic effects of mutations in PERIANTHIA, a gene specifically required for floral organ patterning in ...

Regulation and Identity of Florigen: Flowering Locus T Moves Center Stage [PDF]
, 2008 The transition from vegetative to reproductive growth is controlled by day length in many plant species. Day length is perceived in leaves and induces a systemic signal, called florigen, that moves through the phloem to the shoot apex.
