DNA methylation is reconfigured at the onset of reproduction in rice shoot apical meristem

Nature Communications, 2020
The shoot apical meristem of flowering plants transitions from forming leaves to floral organs. Here Higo et al. show that DNA methylation of many transposons that are hypermethylated in gametes is established in the SAM before flowering, suggesting it ...

Interplay between Proline Metabolism and ROS in the Fine Tuning of Root-Meristem Size in Arabidopsis

Plants, 2022
We previously reported that proline modulates root meristem size in Arabidopsis by controlling the ratio between cell division and cell differentiation.

Novel genome editing approaches to manipulate apical meristem activity for crop yield

Frontiers in Plant Science
Meristem function underlies organogenesis and yield potential in crop species, and its regulation depends on the crosstalk of genetic and hormonal networks that balance stem-cell niche maintenance and differentiation.

Introduction and multiplication in vitro of garlic culture var. Morado Barranquino

Revista Peruana de Biología, 2013
We determine the effect of modified culture medium using different growth regulators concentrations (auxins / cytokinins) for regeneration and propagation of in vitro garlic plants (Allium sativumL.) var. ‘Morado Barrran-quino’.

Brassinosteroids Modulate Meristem Fate and Differentiation of Unique Inflorescence Morphology in Setaria viridis [PDF]

The Plant Cell, 2017
Inflorescence architecture is a key determinant of yield potential in many crops and is patterned by the organization and developmental fate of axillary meristems. In cereals, flowers and grain are borne from spikelets, which differentiate in the final iteration of axillary meristem branching.

Maize Anther Development Involves Translated Open Reading Frames From 3′ Untranslated Regions

Advanced Science, EarlyView.
This study examined the translation activity across ten stages of maize anther development, integrating transcriptome and small‐peptide data. It linked mutations in translated 3' ORFs to anther sterility, exemplified by Zm00001eb417050_3' ORF (known as APV1). In addition, the data indicated that maize anthers could assimilate CO2 through the stomata in

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

Applications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

Crystal structure of the plant receptor-like kinase TDR in complex with the TDIF peptide

Nature Communications, 2016
The TDF peptide interacts with the leucine-rich repeat receptor-like kinase TDR to regulate meristem differentiation in plants. Here, the authors solve the structure of the extracellular domain of TDR in complex with TDIF and propose a mechanism for TDIF

Shoot meristem maintenance is controlled by a GRAS -gene mediated signal from differentiating cells [PDF]

Genes & Development, 2002
Plant shoot development depends on the perpetuation of a group of undifferentiated cells in the shoot apical meristem (SAM). In the Petunia mutant hairy meristem ( ham ), shoot meristems differentiate ...

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
