Behavior of Leaf Meristems and Their Modification [PDF]
Frontiers in Plant Science, 2015 A major source of diversity in flowering plant form is the extensive variability of leaf shape and size. Leaf formation is initiated by recruitment of a handful of cells flanking the shoot apical meristem (SAM) to develop into a complex three-dimensional

Going with the wind – Adaptive dynamics of plant secondary meristems
Mechanisms of Development, 2013 Highlights ► We discuss the role of secondary meristems in the adaptation of plant growth forms. ► We highlight the integration of environmental inputs into plant growth regulation. ► Branching and secondary growth shape the plant body.

A Dynamic Model for Stem Cell Homeostasis and Patterning in Arabidopsis Meristems
PLoS ONE, 2010 Plants maintain stem cells in their meristems as a source for new undifferentiated cells throughout their life. Meristems are small groups of cells that provide the microenvironment that allows stem cells to prosper.

Under siege: virus control in plant meristems and progeny
The Plant Cell, 2021 In the arms race between plants and viruses, two frontiers have been utilized for decades to combat viral infections in agriculture. First, many pathogenic viruses are excluded from plant meristems, which allows the regeneration of virus-free plant ...

Meristematic Connectome: A Cellular Coordinator of Plant Responses to Environmental Signals?
Cells, 2021 Mechanical stress in tree roots induces the production of reaction wood (RW) and the formation of new branch roots, both functioning to avoid anchorage failure and limb damage.

Transcriptional landscapes of floral meristems in barley
Science Advances, 2021 High-resolution spatial transcriptomics identifies previously unknown regulators for barley floral meristem development. Organ development in plants predominantly occurs postembryonically through combinatorial activity of meristems; therefore, meristem ...

Quantitative Plant Biology, 2022 Meristems in land plants share conserved functions but develop highly variable structures. Meristems in seed-free plants, including ferns, usually contain one or a few pyramid-/wedge-shaped apical cells (ACs) as initials, which are lacking in seed plants.

Cell Division and Meristem Dynamics in Fern Gametophytes
Plants, 2023 One of the most important questions in all multicellular organisms is how to define and maintain different cell fates during continuous cell division and proliferation. Plant meristems provide a unique research system to address this fundamental question

NAC103 mutation alleviates DNA damage in an Arabidopsis thaliana mutant sensitive to excess boron
Frontiers in Plant Science, 2023 Excess boron (B) is toxic to plants and thereby causes DNA damage and cell death in root meristems. However, the underlying mechanisms which link boron and DNA damage remain unclear.
