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.

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.

Floral initiation in response to planting date reveals the key role of floral meristem differentiation prior to budding in canola (Brassica napus L.) [PDF]

Frontiers in Plant Science, 2016
In Brassica napus, floral development is a decisive factor in silique formation, and it is influenced by many cultivation practices including planting date.

The impact of asymmetrical gene expression on the development of spike morphology in Triticum aestivum [PDF]

iMetaOmics
Wheat yield is primarily determined by panicle density per unit area, grain count per spike, and grain weight. The proliferation of wheat spikes affects both the number of grains per spike and grain weight. However, the molecular regulatory mechanisms of

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 ...

MERISTEM-DEFECTIVE regulates the balance between stemness and differentiation in the root meristem through RNA splicing control

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.

Old school, new rules: floral meristem development revealed by 3D gene expression atlases and high-resolution transcription factor–chromatin dynamics

Frontiers in Plant Science, 2023
The intricate morphology of the flower is primarily established within floral meristems in which floral organs will be defined and from where the developing flower will emerge.

Paradigm and Framework of WUS-CLV Feedback Loop in Stem Cell Niche for SAM Maintenance and Cell Identity Transition

Agronomy, 2022
Shoot apical meristem (SAM) consists of stem cells that act as a reservoir for the aerial growth. It plays an important role in the differential architectural development in plants.

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
