Differential spatial distribution of miR165/6 determines variability in plant root anatomy [PDF]
, 2017 A clear example of interspecific variation is the number of root cortical layers in plants. The genetic mechanisms underlying this variability are poorly understood, partly due to the lack of a convenient model.

Frontiers in Plant Science, 2016 Root growth and the architecture of the root system in Arabidopsis are largely determined by root meristematic activity. Legume roots show strong developmental plasticity in response to both abiotic and biotic stimuli, including symbiotic rhizobia ...

Re-induction of the cell cycle in the Arabidopsis post-embryonic root meristem is ABA-insensitive, GA-dependent and repressed by KRP6 [PDF]
, 2016 Seeding establishment following seed germination requires activation of the root meristem for primary root growth. We investigated the hormonal and genetic regulation of root meristem activation during Arabidopsis seed germination. In optimal conditions,

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

Cadmium and arsenic-induced-stress differentially modulates Arabidopsis root architecture, peroxisome distribution, enzymatic activities and their nitric oxide content [PDF]
, 2020 In plant cells, cadmium (Cd) and arsenic (As) exert toxicity mainly by inducing oxidative stress through an imbalance between the production of reactive oxygen species (ROS) and reactive nitrogen species (RNS), and their detoxification. Nitric oxide (NO)

Unique Cellular Organization in the Oldest Root Meristem [PDF]
Current Biology, 2016 Roots and shoots of plant bodies develop from meristems-cell populations that self-renew and produce cells that undergo differentiation-located at the apices of axes [1].The oldest preserved root apices in which cellular anatomy can be imaged are found in nodules of permineralized fossil soils called coal balls [2], which formed in the Carboniferous ...

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 ...

Transition zone cells reach G2 phase before initiating elongation in maize root apex
Biology Open, 2017 Root elongation requires cell divisions in the meristematic zone and cell elongation in the elongation zone. The boundary between dividing and elongating cells is called the transition zone.

Overexpression of the WOX5 gene inhibits shoot development
Plant Signaling & Behavior, 2022 WUSCHEL-RELATED HOMEOBOX 5 (WOX5) is a member of the WUSCHEL (WUS) homeodomain transcription factor family. WOX5 is expressed mainly in the quiescent center (QC) and confers stem cell identity in the root apical meristem (RAM).
