Short-range control of cell differentiation in the Arabidopsis root meristem
Nature, 1997 Meristems are distinctive regions of plants that have capacity for continuous growth. Their developmental activity generates the majority of plant organs. It is currently unknown how cell division and cell differentiation are orchestrated in meristems, although genetic studies have demonstrated the relevance of a proper balance between the two ...

Spatial Coordination between Stem Cell Activity and Cell Differentiation in the Root Meristem [PDF]
Developmental Cell, 2013 A critical issue in development is the coordination of the activity of stem cell niches with differentiation of their progeny to ensure coherent organ growth. In the plant root, these processes take place at opposite ends of the meristem and must be coordinated with each other at a distance. Here, we show that in Arabidopsis, the gene SCR presides over

Translatome analyses capture of opposing tissue-specific brassinosteroid signals orchestrating root meristem differentiation. [PDF]
Proc Natl Acad Sci U S A, 2015 Significance Brassinosteroid (BR) differentially regulates the number of stem cell daughters in the root meristem. How its activity coordinates and maintains the meristem size remains unknown. We show that BR signal coordinates root growth by evoking distinct and often opposing responses in specific tissues.

Comparative transcriptomic analysis of maize ear heterosis during the inflorescence meristem differentiation stage. [PDF]
BMC Plant Biol, 2022 Abstract Background: Heterosis is widely used in many crops and is important for global food safety. Maize is one of the most successful crops to take advantage of heterosis. Gene expression patterns have an effect with the development of maize ear. However, the mechanisms of heterosis on transcriptional-level control are only partly understood.

LOST MERISTEMS genes regulate cell differentiation of central zone descendants in Arabidopsis shoot meristems. [PDF]
The Plant journal : for cell and molecular biology, 2010 Meristems of seed plants continuously produce new cells for incorporation into maturing tissues. A tightly controlled balance between cell proliferation in the center and cell differentiation at the periphery of the shoot meristem maintains its integrity.

Cytokinins Determine Arabidopsis Root-Meristem Size by Controlling Cell Differentiation [PDF]
Current Biology, 2007 Plant postembryonic development takes place in the meristems, where stem cells self-renew and produce daughter cells that differentiate and give rise to different organ structures. For the maintenance of meristems, the rate of differentiation of daughter cells must equal the generation of new cells: How this is achieved is a central question in plant ...

Development, 2023 ABSTRACT Plants respond to environmental stresses through controlled stem cell maintenance and meristem activity. One level of gene regulation is RNA alternative splicing. However, the mechanistic link between stress, meristem function and RNA splicing is poorly understood.

The DME demethylase regulates sporophyte gene expression, cell proliferation, differentiation, and meristem resurrection [PDF]
Proceedings of the National Academy of Sciences, 2021 The flowering plant life cycle consists of alternating haploid (gametophyte) and diploid (sporophyte) generations, where the sporophytic generation begins with fertilization of haploid gametes. InArabidopsis, genome-wide DNA demethylation is required for normal development, catalyzed by the DEMETER (DME) DNA demethylase in the gamete companion cells of

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 ...

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 ...
