Mechanosensing and anesthesia of single internodal cells of Chara

Plant Signaling & Behavior
The giant (2–3 × 10−2 m long) internodal cells of the aquatic plant, Chara, exhibit a rapid (>100 × 10−6 m s−1) cyclic cytoplasmic streaming which stops in response to mechanical stimuli.

Diffusive Promotion by Velocity Gradient of Cytoplasmic Streaming (CPS) in Nitella Internodal Cells.

PLoS ONE, 2015
Cytoplasmic streaming (CPS) is well known to assist the movement of nutrients, organelles and genetic material by transporting all of the cytoplasmic contents of a cell.

Dynamics and stabilization mechanism of mitochondrial cristae morphofunction associated with turgor-driven cardiolipin biosynthesis under salt stress conditions

Scientific Reports, 2022
Maintaining energy production efficiency is of vital importance to plants growing under changing environments. Cardiolipin localized in the inner mitochondrial membrane plays various important roles in mitochondrial function and its activity, although ...

Cytoskeleton as a generator of characteristic physical properties of plant cells: ‘cell wall,’ ‘large vacuole,’ and ‘cytoplasmic streaming’

Biophysics and Physicobiology
As sessile organisms, plants must constantly adapt to ever-changing environmental conditions. To survive in their habitats, plants have evolved characteristic cellular features that make the cells rigid yet dynamic.

Real-Time Fluorescence Imaging Platform for Screening Arbuscular Mycorrhizal Fungi by Hyphal Transport Kinetics

Microbiology Research
Arbuscular mycorrhizal (AM) fungi form mutualistic symbioses with about 80% of land plants and play a key role in improving host inorganic phosphate (Pi), nitrogen, and water acquisition.

Intracellular signalling by diffusion: Can waves of hydrogen peroxide transmit intracellular information in plant cells?

Frontiers in Plant Science, 2012
Amplitude- and frequency-modulated waves of Ca2+ ions transmit information inside cells. Reactive Oxygen Species, specifically hydrogen peroxide, have been proposed a similar role in plant cells.

Distinct functions of microtubules and actin filaments in the transportation of the male germ unit in pollen

Nature Communications
Flowering plants rely on the polarized growth of pollen tubes to deliver sperm cells (SCs) to the embryo sac for double fertilization. In pollen, the vegetative nucleus (VN) and two SCs form the male germ unit (MGU).

The circular F-actin bundles provide a track for turnaround and bidirectional movement of mitochondria in Arabidopsis root hair. [PDF]

PLoS ONE, 2014
The movement of organelles in root hairs primarily occurs along the actin cytoskeleton. Circulation and "reverse fountain" cytoplasmic streaming constitute the typical forms by which most organelles (such as mitochondria and the Golgi apparatus) in plant
