Control of Arabidopsis apical-basal embryo polarity by antagonistic transcription factors. [PDF]

open access: yes, 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 ...

Growth and development of the root apical meristem

open access: yesCurrent Opinion in Plant Biology, 2012
A key question in plant developmental biology is how cell division and cell differentiation are balanced to modulate organ growth and shape organ size. In recent years, several advances have been made in understanding how this balance is achieved during root development.

Pattern formation during de novo assembly of the Arabidopsis shoot meristem [PDF]

open access: yes, 2007
Most multicellular organisms have a capacity to regenerate tissue after wounding. Few, however, have the ability to regenerate an entire new body from adult tissue. Induction of new shoot meristems from cultured root explants is a widely used, but poorly

Activation of embryo during rape (Brassica napus L.) seed germination. I. Structure of embryo and organization of root apical meristem

open access: yesActa Societatis Botanicorum Poloniae, 2015
The Structure of the mature rape embryo was examined on longitudirna microtome sections, and1, its developmental interpretation is given, based on the author's own studies and literature data.

Analysis of chlorophyll fluorescence reveals stage specific patterns of chloroplast-containing cells during Arabidopsis embryogenesis [PDF]

open access: yes, 2010
http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-97602010000100012&lng=es&nrm=isoThe basic body plan of a plant is established early in embryogenesis when cells differentiate, giving rise to the apical and basal regions of the embryo.

Expression of Cell Cycle Genes During Sesbania rostrata Stem Nodule Development

open access: yesMolecular Plant-Microbe Interactions, 1997
Upon infection of Sesbania rostrata with Azorhizobium caulinodans, nodules are formed on roots and stems. Stem nodules develop from abundantly distributed dormant root primordia.

Establishment of embryonic shoot–root axis is involved in auxin and cytokinin response during Arabidopsis somatic embryogenesis

open access: yesFrontiers in Plant Science, 2015
Auxin and cytokinin signaling participates in regulating a large spectrum of developmental and physiological processes in plants. The shoots and roots of plants have specific and sometimes even contrary responses to these hormones.

A Systems Biology Approach to Identify Essential Epigenetic Regulators for Specific Biological Processes in Plants

open access: yesPlants, 2021
Upon sensing developmental or environmental cues, epigenetic regulators transform the chromatin landscape of a network of genes to modulate their expression and dictate adequate cellular and organismal responses.

Hormone interactions at the root apical meristem

open access: yesPlant Molecular Biology, 2008
Plants exhibit an amazing developmental flexibility. Plant embryogenesis results in the establishment of a simple apical-basal axis represented by apical shoot and basal root meristems. Later, during postembryonic growth, shaping of the plant body continues by the formation and activation of numerous adjacent meristems that give rise to lateral shoot ...

MicroRNA MIR396 regulates the switch between stem cells and transit-amplifying cells in arabidopsis roots [PDF]

open access: yes, 2015
To ensure an adequate organ mass, the daughters of stem cells progress through a transit-amplifying phase displaying rapid cell division cycles before differentiating.
