A quantitative and dynamic model for plant stem cell regulation. [PDF]
PLoS ONE, 2008 Plants maintain pools of totipotent stem cells throughout their entire life. These stem cells are embedded within specialized tissues called meristems, which form the growing points of the organism.

It’s Time for a Change: The Role of Gibberellin in Root Meristem Development
Frontiers in Plant Science, 2022 One of the most amazing characteristics of plants is their ability to grow and adapt their development to environmental changes. This fascinating feature is possible thanks to the activity of meristems, tissues that contain lasting self-renewal stem ...

L1 Division and Differentiation Patterns Influence Shoot Apical Meristem Maintenance [PDF]
Plant Physiology, 2006 Abstract Plant development requires regulation of both cell division and differentiation. The class 1 KNOTTED1-like homeobox (KNOX) genes such as knotted1 (kn1) in maize (Zea mays) and SHOOTMERISTEMLESS in Arabidopsis (Arabidopsis thaliana) play a role in maintaining shoot apical meristem indeterminacy, and their misexpression is ...

microRNA165 and 166 modulate response of the Arabidopsis root apical meristem to salt stress
Communications Biology, 2023 In plants, developmental plasticity allows for the modulation of organ growth in response to environmental cues. Being in contact with soil, roots are the first organ that responds to various types of soil abiotic stress such as high salt concentration ...

Plants, 2023 The continuous growth of roots depends on their ability to maintain a balanced ratio between cell production and cell differentiation at the tip. This process is regulated by the hormonal balance of cytokinin and auxin.

The Rate of Cell Differentiation Controls the Arabidopsis Root Meristem Growth Phase [PDF]
Current Biology, 2010 Upon seed germination, apical meristems grow as cell division prevails over differentiation and reach their final size when division and differentiation reach a balance. In the Arabidopsis root meristem, this balance results from the interaction between cytokinin (promoting differentiation) and auxin (promoting division) through a regulatory circuit ...

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.

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 ...

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 ...

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 ...
