Pectin is an abundant cell wall polysaccharide with essential roles in various biological
processes. The structural diversity of pectins, along with the numerous combinations of the …

Charophytes (Streptophyta) represent a diverse assemblage of extant green algae that are
the sister lineage to land plants. About 500–600+ million years ago, a charophyte progenitor …

Plant cells divide their cytoplasmic content by forming a new membrane compartment, the
cell plate, via a rerouting of the secretory pathway toward the division plane aided by a …

Polar callose deposition into the extracellular matrix is tightly controlled in time and space.
Its presence in the cell wall modifies the properties of the surrounding area, which is …

The mechanism of cell division has undergone significant alterations during the evolution
from aquatic streptophyte algae to land plants. Two new structures evolved, the cytokinetic …

Charophytes are the group of green algae whose ancestral lineage gave rise to land plants
in what resulted in a profoundly transformative event in the natural history of the planet …

One of the most transformative events in the history of life on earth was the transition of
plants from water to land approximately 470 million years ago. Within the Charophyte green …

The preprophase band (PPB) is a transient cytokinetic structure that marks the future division
plane at the onset of mitosis. The PPB forms a dense cortical ring of mainly microtubules …

Zygnematophycean algae represent the streptophyte group identified as the closest sister
clade to land plants. Their phylogenetic position and growing genomic resources make …

Phenotypic plasticity allows a plant cell to alter its structure and function in response to
external pressure. This adaptive phenomenon has also been important in the evolution of …
