Comparative Ontogeny of Hermaphrodite and Pistillate Florets in Helianthus annuus L. (Asteraceae)
Notulae Scientia Biologicae, 2012 The inflorescence of Helianthus annuus L. has two types of flowers (or florets) on a single capitulum; central hermaphrodite disc florets and peripheral pistillate ray florets.

Proline affects the size of the root meristematic zone in Arabidopsis [PDF]
, 2015 We reported previously that root elongation in Arabidopsis is promoted by exogenous proline, raising the possibility that this amino acid may modulate root growth.

FTIP-Dependent STM Trafficking Regulates Shoot Meristem Development in Arabidopsis
Cell Reports, 2018 Summary: Organogenesis in higher plants occurs in the shoot meristem, which contains pluripotent stem cells. Here, we show that two multiple C2 domain and transmembrane region proteins, FT INTERACTING PROTEIN 3 (FTIP3) and FTIP4, play an essential role ...

The Arabidopsis thaliana checkpoint kinase WEE1 protects against premature vascular differentiation during replication stress [PDF]
, 2011 A sessile lifestyle forces plants to respond promptly to factors that affect their genomic integrity. Therefore, plants have developed checkpoint mechanisms to arrest cell cycle progression upon the occurrence of DNA stress, allowing the DNA to be ...

Differential CLE peptide perception by plant receptors implicated from structural and functional analyses of TDIF-TDR interactions. [PDF]
PLoS ONE, 2017 Tracheary Element Differentiation Inhibitory Factor (TDIF) belongs to the family of post-translationally modified CLE (CLAVATA3/embryo surrounding region (ESR)-related) peptide hormones that control root growth and define the delicate balance between ...

eLife, 2021 Stem cell homeostasis in plant shoot meristems requires tight coordination between stem cell proliferation and cell differentiation. In Arabidopsis, stem cells express the secreted dodecapeptide CLAVATA3 (CLV3), which signals through the leucine-rich ...

ABA mediates PEG-mediated premature differentiation of root apical meristem in plants [PDF]
Plant Signaling & Behavior, 2014 Root apical meristem (RAM) is central for indeterminate growth of plant roots and in sensing environmental stimuli, such as water status. Recently, we reported that PEG8000-simulated mild and moderate osmotic stress induces premature differentiation of RAM, which is a conserved adaptive mechanism in higher plants to cope with water stress.

Cell Reports, 2015 Telomeres are specialized nucleoprotein caps that protect chromosome ends assuring cell division. Single-cell telomere quantification in animals established a critical role for telomerase in stem cells, yet, in plants, telomere-length quantification has ...

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.
